Executive Summary Spectrum is viewed as a key asset for the development of mobile broadband (MBB) and Cellular

Internet of Things (C-IoT). Both high and low frequency bands play a key role for boosting the

adoption of LTE (Long Term Evolution) across the world. In 2012 3GPP has successfully included

APT700 band – corresponding to TV channels from 52 to 69 – (3GPP R11 band 28 for FDD mode

and 3GPP R11 band 44 for TDD mode) into the list of LTE frequencies as per APT (Asia-Pacific

Telecommunity, a cross-governments organization among APAC countries to deal with spectrum

policies) and ITU official agreements in 2010/11.

The following world map summarizes the decision to use APT700MHz and US700.

Fig1: APT700 versus US700 Adoption (Status @2016)

Low band APT700MHz LTE deployment is highly recommended to deliver broadband experience

in rural areas and provide exceptional good wall penetration for a powerful indoor coverage.

Indeed APT700MHz is classified as a low band (spectrum below 1GHz). It offers broad coverage,

compared to high bands such as 1800MHz and 2600MHz, allowing a significant CAPEX reduction.

In addition APT700 brings additional capacity within the low bands category and makes it a golden



spectrum. Finally in city area APT700 has a very good wall penetration to provide consistent indoor

coverage to greatly benefit the end-users experience.

APT700MHz is already gaining momentum for LTE services, and large scale deployments have

started since 2014. Currently there are 26 commercial LTE networks using band 28 across 14

countries. Large countries such as Australia, Brazil, Japan and Philippines have already

successfully kicked-off LTE services in using band 28. In addition more than 10 LTE operators

have implemented inter-bands carrier aggregation in using band 28.

In 2013, Huawei was among the first vendors to conduct APT700MHz field trials with operators to

show the band’s excellent characteristics for indoor coverage and rural coverage. As of today

Huawei commercial LTE RAN equipment kit is fully deployed in 11 LTE projects in using band 28.

Several hundreds of commercial LTE devices support band 28 across all types of form factors. It

provides a strong commitment to LTE operators for being confident to rollout APT700 band.

This document mainly addresses the FDD mode of APT700 (3GPP band 28). Industry support for

the APT700 FDD band plan is already strong. Indeed whereas APT700 provides both FDD and

TDD arrangements; it is the FDD mode that has gained global support from wireless industry

players and regulators in Asia, South America and recently Europe & Middle East markets. All

together it represents a market size exceeding 4 billion people! The FDD configuration is

standardised in 3GPP R11 (band 28) based on 2 x 45MHz arrangement, with 10MHz guard band

between downlink and uplink. APT700 FDD band plan is exactly defined as 703-748MHz for the

uplink, 10MHz guard band and 758-803MHz for the downlink. Sometimes APT700 FDD mode is

referred as APT700 lower duplexer and APT700 upper duplexer (see the following figure).

Especially it is important to notice that both Asia and South America use the whole APT700 band

(2x45MHz) whereas Europe & Middle East Africa region considers APT700 lower duplexer only in

order to match previous DD800 allocation.

Recently 3GPP has approved “an extension” to band 28 which is band 68 (698-728MHz /

753-783MHz). It is part of 3GPP R13. It is a swift of 5MHz from APT700 lower duplexer and it is

mainly relevant for Region 1.

Tab1: APT700 Standardization Documents

In 3GPP R12, R13 and on-going R14 there are already several carrier aggregation (CA) scenarios

being approved. However depending on countries regulations for the allocation of LTE spectrum

https://www.citel.oas.org/en/SiteAssets/PCCII/Final-Reports/P2!R-2710r1_e.pdf



(APT700 and other bands) as well as operators spectrum strategy, 3GPP will have to extend the

number of LTE-Advanced inter-band carrier aggregation scenarios in using band 28. 3GPP TS

36.104 lists all carrier aggregation scenarios being approved for each 3GPP release.

The list of LTE-Advanced carrier aggregation scenarios already approved by 3GPP and involving

band 28 is given into the following table (06-2016 status).

1. APT700 Development Highlights

1.1 APT700 Industry Updates

APT700 has been widely recognized as a “Digital Dividend” spectrum for LTE services. All regions

around the world (with few exception of America) have decided or have an intention to adopt this

band as an LTE spectrum. The potential market size for APT700 covers more than 4 billion people.

49 countries and territories allocated, committed to, or recommend APT700 FDD (band 28) for LTE

system deployments (GSA Report titled “4G MARKET and TECHNOLOGY UPDATE”,

28-07-2016):

LAC region: Argentina, Brazil, Chile, Colombia, Costa Rica, Curaçao, Dominican Republic,

Ecuador, Honduras ,Mexico, Panama, Peru, Suriname, Venezuela. Some of these countries have

already completed the Digital Switch-Over or are in the process for doing it such as Brazil which is

currently implementing the digital switch-over to free APT700 as follows:

Early pilot deadline set in 11-2015 to free APT700 band for mobile operators in Rio Verde

Followed by 5 major cities in 2016 – Brasilia (04-2016), Sao Paolo (05-2016), Belo

Horizonte (06-2016), Goiania (08-2016) and Rio de Janeiro (11-2016)

During 2017 a further 15 cities/regions are scheduled to switch off analogue services

between 06-2017 and 11-2017 that year,

And in 2018 – between 07-2018 and 11-2018 – another 16 named cities plus all other

regions make the switchover according to the ministry’s schedule, with the final analogue

shutdown scheduled for 25-11-2018

APAC/Oceania: Afghanistan, Australia, Bangladesh, Bhutan, Brunei, Cambodia, Fiji, India,

Indonesia, Japan, Laos, Malaysia, Myanmar, Nepal, New Zealand, Pakistan, Papua New Guinea,

Singapore, South Korea, St. Maarten, Taiwan, Thailand, Tonga, Vanuatu, Vietnam

Japan operators deploy APT700 Upper Duplexer for LTE services since 2015. Note that in Japan

there are DTV systems up to 710MHz and therefore the complete APT700 band cannot be

allocated to mobile operators at the time being.

Australia and New Zealand operators have started to use APT700 since 2014 and have gradually

expanded it across both countries.



Telecom Spark New Zealand has been one of the first operators to begin a LTE pre-commercial

rollout in using APT700 spectrum in June 2014, alongside partner Huawei Technologies. And this

non-commercial trial, involving selected customers, provided valuable first-hand experience to

qualify the future network building. Then Telecom Spark (formerly Telecom New Zealand)

launched a wireless broadband service for people in rural areas of the country using 700MHz for its

4G LTE services since October 2014. The new service marketed as a fixed broadband alternative

for home and business use rather than a true mobile product, and the Spark says it provided

speeds up to 10 times faster than those available via the government-backed Rural Broadband

Initiative (RBI) which uses 3G technology to reach outlying areas.

Currently a wide range of LTE terminals (smartphone, routers, tablets) supporting APT700 band is

available is New Zealand.

Globe Telecom Philippines accelerated the deployment of LTE radio sites using the 700 MHz band

in July 2016, and it targets several hundreds of LTE 700 MHz cell sites by the end of 2016.

According to Globe, the LTE 700 MHz cell sites cover major business districts and

highly-urbanized and populated areas in the country, as subscribers using LTE-powered devices

are steadily increasing in these areas.

MEA: UAE confirmed the adoption of the APT700 Lower Duplexer (2 x 30MHz).

In Middle East region in 05-2013 UAE TRA has released a white paper titled “Channel Planning &

Availability for Mobile Broadband in the UAE” in favor of the adoption of both DD800MHz band and

Lower APT700 Duplexer band in Africa, Europe and Middle East countries. As per UAE TRA’s

white paper the following 2 key information have been highlighted:

1. “Many Arab countries showed support for the UAE 700MHz channel plan during the

March 2013 Arab Spectrum Management Group Meeting held in Dubai” (e.g. use of both

DD800MHz band and Lower APT700 Duplexer band)

2. The Lower APT700 Duplexer band (703-733MHz / 758-788MHz) to free for the use of

mobile communications in UAE by the end of 2013

APT700 Lower Duplexer is also the preferred frequency arrangement for 700 MHz allocations in

Europe and throughout ITU Region 1 in Africa.

Europe: Notwithstanding the EU Council position (see below), several actions are underway or

planned in Austria, Finland, Iceland, Slovenia, Sweden and UK to free the Lower APT700 Duplexer

for mobile communications. France and Germany have already auctioned APT700 Band 28.



The number of commitments in Europe should be even much higher. On May 26, 2016 the EU

Council adopted a general approach on a draft decision aimed at boosting broadband services.

The 700 MHz band would be made available for wireless broadband in Europe by 2020. According

to the Council position, EU countries must reassign the 700 MHz band (694-790MHz) to wireless

broadband services under harmonised technical conditions by 30 June 2020. If they are unable to

do this they may decide, for duly justified reasons, to delay the availability of the band by up to two

years. Member states must adopt a 'national roadmap' by 30 June 2018, setting out how they will

implement the decision. These roadmaps are to be made public.

Also, a large border coordination agreement between Belgium, France, Germany, Ireland,

Luxembourg, the Netherlands, the United Kingdom, to manage the TV carriers in the 700MHz

band has been approved. Thus, all these countries will be able to speed up the 700MHz

deployment e.g. in some regions in France, the deployment has already started.

Note that APT700 Lower Duplexer is fully consistent with 3GPP band 20 (DD800) which is

currently used in some Africa countries, several European and Middle East countries. It brings

significant benefits to mobile operators in region 1:

Expectation to get a large devices eco-system using APT700 due to the huge market size

in terms of population and number of operators

Easy international roaming

Less cross-border interference

APT700 global adoption is steadily gaining momentum over the past few years and its

development has been quite fast in recent times. This represents a big opportunity for spectrum

harmonization.

Let’s put it in that way: “APT700 has the potential to become a band as powerful as 900MHz

which provides a huge advantage for mobile operators since more than 20 years”.

Moreover APT700 Upper Duplexer and APT700 Lower Duplexer are fully consistent among each

other. Therefore in medium term APT700 FDD mode can be viewed as a global band which can be

favour the international roaming for LTE services among all regions (except very few countries in

America).

As of today APT700 band 28 is licensed to mobile operators in several countries, including:

Argentina, Australia, Bhutan, Brazil, Chile, Ecuador, Fiji, France*, Germany*, Japan, Mexico

(on-going allocation), New Zealand, Panama, Papua New Guinea, Philippines, South Korea

(particular case in South Korea about PPDR services which is deployed by 2 operators “Korea

Telecom & SK Telecom” and this service uses a part of the band 28: 2*10MHz ), Suriname, Taiwan



and Vanuatu.

*) Compatible with the lower duplexer arrangement of APT700 (703-733 / 758-788MHz)

Fig4: World Map Adoption for APT700 Band by LTE Operators (Status @08-2016)

There are currently 26 operators in 15 countries which have successfully deployed LTE in using

APT700 band 28 (see world map above). These countries have already defined and implemented

a Digital TV Switch-Over time-schedule roadmap. The following table provides some examples of

such a DSO migration which have been coordinated by local TRAs.

1.2 APT700 Auctions Status and Forecasts

Currently APAC, LATAM and Central America regions have expressed great interests for

allocating APT700 to operators. Several TRAs (Telecom Regulator Authorities) have already

announced official results for the allocation of 3GPP band 28 to mobile operators e.g.:

Japan: In June 2012 Japan MIC has successfully allocated APT-700MHz (FDD mode) to

NTT Docomo, eAccess and KDDI. Each of them has won a bandwidth of 10MHz for this

band. These 3 Japanese operators have already started to use APT700 for commercial

services since 2015.

Australia: In May 2013 Australia local regulator ACMA has carried out APT700 spectrum

auction (band 28). Both Optus and Telstra have successfully secured a block of APT700.

Telstra have been granted a block of 20MHz and Optus has received a block of 10MHz.

Commercial LTE services using APT700 are offered since 2014 in Australia.

Taiwan (China): In October 2013 Taiwan has awarded APT700 band to Asia Pacific

Telecom (APT), Far EasTone (FET), Taiwan Mobile (TWM) and a Greenfield operator

Ambit (belonging to Foxconn Group). All operators have already commercially deployed

APT700 band for LTE.

New Zealand: In October 2013 New Zealand Ministry has allocated APT700 (band 28) to

1.3 Huawei APT700 Activities

Huawei has been involved into the APT700 band standardization since the early APT activities in

2010. Huawei has already supplied commercial LTE eNodeBs to support APT700 band (FDD

mode) in 11 commercial projects.

Huawei RF solution is based on its latest RRU equipment (named as Huawei Blade RRU). Huawei

Blade RRU reduces the base station installation time and saves the eNodeB energy consumption,

based on advanced power amplifier and power supply technology (around 20%-30% lower power

consumption than the industry average). Therefore Huawei is fully ready to support operators

looking to implement LTE using APT700 band.

The eNodeB configuration for adding APT700 is quite straight forward as depicted into the

following table.

wideband antenna or add a new antenna (depending on legacy site configuration)

There are 2 pre-conditions for re-using legacy antenna: 1. Assuming MIMO2x2

configuration there is a need to have 2 available ports

2. Legacy wideband antenna needs to support APT700

Tab5: Huawei APT700 Support for LTE eNodeB (Already Commercially Deployed)



As an end-to-end solution technology leader, Huawei does not only provide network equipment

only. Indeed Huawei will offer commercial LTE terminals supporting APT700 since 2014.

In February 2014 the Global 700M Alliance was founded with the active support of Huawei to

promote the adoption of APT700. With persistent efforts of the Global 700M Alliance, the APT700

frequency band (Band28) is assigned or scheduled for assignment in more than 50 countries and

regions by June 2016.

Up to now, 26 operators have deployed pre-commercial and commercial networks on APT700

across 14 countries and regions. The roll out of new services, such as high definition video and

voice (VoLTE) services, on the LTE 700 MHz band is quickly gaining popularity. Operators have

chosen to fully unlock the true potential of wide coverage and deep indoor penetration capabilities

in using this frequency band. In addition it gives an excellent opportunity for operators to expand

their business into vertical industries, e.g. using 3GPP R13 NB-IoT for Cellular Internet of Things.

The maturation of the 700MHz industry chain will accelerate the deployment of APT700 networks

around the world, which facilitates the rapid ICT transformation and enables a larger proportion of

the world population to enjoy the benefits of mobile broadband development.

2 APT700M Ecosystem Status

2.1 APT700 Network Equipment Readiness

LTE has been deployed since 2009. According to GSA, there are 521 networks running in variety

of spectrums around the world as at June. 2016. APT700 is adopted in 3GPP R11. Since LTE is no

longer a new concept, 700MHz is just a variation to a new RF module for the network.

All the major RAN infrastructure vendors (Huawei, Ericsson, Nokia, Samsung, and ZTE) have

announced support for Band 28; as part of their radio units’ portfolio. All of them have already

announced commercial LTE deployments using APT700 band 28 since 2014.

2.2 More and More LTE Devices Supporting APT700

The APT700 FDD band plan (Band 28) represents a major opportunity for the global spectrum



harmonization of LTE systems. It is obvious that it can pave the way for ensuring the greatest

economies of scale for devices and providing additional capacity for mobile broadband, and last

but not the least for supporting the international roaming.

Hence, the popularity of APT 700MHz band plan has grown and has been accepted by most of

countries in the Asia-Pacific, South America and Central America regions since 2010/2012.

Recently in 2015 countries in region 1 (Africa & Middle East, Europe) have officially decided to

support APT700 Lower Duplexer (see ECC/DEC/ (15)01 & EC Decision (EU) 2016/687 for Europe

/ ITU WRC 2012: mobile allocation and IMT identification).

Chipsets suppliers have released commercial products since 2013 and first commercial terminals

were released in 2014. Today there are ~400 commercial LTE/LTE-Advanced terminals being able

to support APT700 band 28. The main stream chipset manufacturers have supported Band 28

(Huawei Hisilicon, Qualcomm) since 2013 as per the following table.

Chipset Manufacturer APT700 (Band28) Support

Huawei Hisilicon 2013Q3

Intel 2014H2

Qualcomm 2013Q3

Tab6: Chipsets Suppliers Support of APT700 Band 28

Accordingly, device manufacturers have supported Band 28 since 2014.

In addition some operators have already extended their network capabilities in supporting

LTE-Advanced carrier aggregation (CA) in aggregating Band 28 and other 3GPP bands. Several

CA scenarios have already been approved as per the following table. Several commercial devices

are already available to support the rollout of these commercial CA scenarios.

Tab7: LTE-Advanced CA Scenarios & Projects Based on APT700 (Status @06-2016)

3 APT700 Advantages Analysis

There are various options for LTE operating spectrum. It includes 2600MHz, 2100MHz, 1800MHz,

850MHz, 800MHz and 700MHz. Indeed operators use APT700 band 28 since 2014.

APT700 has several inherent advantages (vaste market adoption, large choice of LTE terminals,

candidate for worldwide roaming (excluding few countries such as Bolivia, Canada, USA), easy

deployment, very good coverage, powerful wall penetration / indoor coverage) which make this



band highly attractive for mobile operators looking for delivering competitive LTE services.

In addition, in several countries, the regulation is based on the neutrality of the uses of the

spectrum and services. This approach provides to the operator full flexibility to optimise the

timeline to deploy a new technology which improve the services to the end user.

3.1 Less Propagation Loss than other Bands

The propagation loss attributed to different bands and the spectral coverage distances differ, even

using the same MAPL (Maximum Allowed Path Loss). Given these differences, link performance

and network dimensioning also vary among different spectrum bands. Therefore, the selected

operating bands have a significant impact on the coverage distance and customer experience

(especially in-building). To efficiently construct a nationwide LTE network with a lower cost,

operators must choose (at least) a band which provides large cell radius for countryside coverage

and powerful indoor/wall penetration capability.

It is obvious that higher frequency bands (>1GHz) have larger propagation loss and low bands

such as APT700 represent a competitive advantage to operators if being used for LTE services

rollout.

Let’s compare APT700 with several other LTE bands. Here one adopts Hata model, which is

divided into Okumura-Hata model and Cost231-Hata model, to calculate the propagation loss.

Okumura-Hata model is suitable for spectrum between 150MHz ~ 1500MHz, while Cost231-Hata

model is used for spectrum above 1500MHz.

The propagation loss among different frequency bands has been calculated and it is shown in

figure Fig5.



Sources: 3GPP, Huawei MI 2014

Fig5: Propagation Loss Comparison among Different Bands (from APT700 to 2.6GHz)

Obviously, for each spectrum, the Rx level is decreasing when the distance is increasing.

Meanwhile, the lower band has a better Rx level than other higher bands when they have the same

distance to cover.

So, 700MHz, compared to 800MHz, 900MHz, 1800MHz, 2100MHz, and 2600MHz, has the best

Rx level. Several operators have fully taken into considerations this argument when deploying LTE

in less populated areas.

3.2 Better Spectrum Efficiency

At 4km, for outdoor coverage, for the same throughput, for the same macro site design, for the

same EIRP and for one macro site case, one needs a bandwidth of:

10MHz for 700MHz

20MHz for 1400MHz

100MHz for 3500MHz



3.3 Better Indoor Coverage & Wall Penetration than other Bands

The indoor RSRP is decreasing while the inter site distance is increasing from dense urban to rural

areas. It is acknowledged that when the RSRP<-124dBm, only outdoor coverage can be assured,

and therefore the end users inside of buildings cannot get quality signal! As shown in the following

figure, when inter- site distance is 600m, the indoor RSRP of 2600MHz is lower than -124dBm,

which means that the site deployed on 2600MHz only provides outdoor coverage since the indoor

signal is too poor. Under the same conditions, sites deployed on 700MHz can still provide good

enough signal for both outdoor and indoor end users. 700MHz has the best indoor penetration

capability among all bands being used for LTE services as of today (with the exception of

450MHz).

Sources: 3GPP, Huawei MI 2014

Fig6. Indoor RSRP Comparison among Several Bands

3.4 Larger Cell Radius than other Bands

A comparison of the coverage radius of a single site utilizing 700MHz, 900MHz, 1.8GHz, and

2.6GHz is shown in figure Fig5, based on typical link budget parameters and configuration.

It is obvious that a single site coverage area using 700MHz band is almost 3 times larger than

2.6GHz and twice than 1.8GHz.So lower frequency bands such as APT700 bring a significant

coverage benefit to operators.

In other words, to cover the same area, the number of LTE sites deployed with 2.6GHz is 3 times



more than the ones being necessary if using 700MHz (assuming the same spectrum bandwidth for

each band).

If operators utilize multiple bands for their LTE network deployment, there is no doubt that 700MHz

represents a competitive choice for nationwide coverage in order to reduce the sites number, save

the network deployment costs and speed up the deployment progress.

3.5 End user’s Benefits in Using APT700

LTE APT700 network, firstly and obviously, as per previous chapters, provides a better coverage

and better indoor/wall penetration. From an end users’ point of view, LTE network deployed on

APT700 can provide them a better mobile broadband experience. With the macro site, the

subscribers can obtain quality data services anywhere, no matter they are outside or inside

building, and no matter they are in the city center or in a remote rural area.

Firstly due to its propagation capabilities APT700 can deliver consistent cell edge coverage at any

location for highly sensible VoLTE services. APT700 can fulfil all mandatory coverage

requirements and provide operators with a competitive option to provide the very best VoLTE

experience for their subscribers.

Secondly new services such as NB-IoT will be commercially launched in coming months

(estimation of 20+ commercial NB-IoT networks by 2017 as per GSA report on 06-2016). The use

of low bands (<1GHz) should be a primary goal for operators when offering NB-IoT solution and

APT700 is an obvious candidate band. Note that the NB-IoT chipset is fully addressing the APT700

option along with other low bands below 1GHz.

Third at the national level APT700 provides a powerful solution to scale LTE services across the

whole country in order to deliver MBB and IoT capabilities at any location. It is obvious that all

countries -- having already reached a near countrywide LTE coverage – take advantage of

frequency bands below 1GHz. APT700 can help to achieve this goal.

Fourth, APT700 is certainly one of the most competitive low bands associating both coverage

performance and relevant capacity. Please refer to the following chart as per today LTE rollouts in

using low bands (<1GHz).



Sources: Huawei MI 2016

Fig7. LTE Projects Number in Low Bands (<1GHz) vs. Bandwidth (Status @08-2016)

Fifth APT700 is fully capable to be aggregated with other LTE bands in order to support

LTE-Advanced carrier aggregation (CA) throughputs. 3GPPP has already approved several CA

scenarios in using Band 28 and there are commercial references up and running in past 2 years.

Sixth with the progress of global migration of terrestrial TV broadcasting from analogue to digital,

the popularity of the APT 700MHz band plan has grown and has been accepted by many countries

in the Asia-Pacific, South America and the Middle-East regions and even recently in Europe and

Africa. As a result, the global adoption of APT700 band can easily support the international

roaming for LTE devices allowing end-users to connect their preferred MBB network all around the

world.

3.6 Large Economy of Scale for APT700M

Due to the strong adoption of mobile devices including smart phones, tablets as well as laptops,

mobile-data traffic continues to rapidly grow. It is expected a 12 times increase by 2018 (to

compare to 2010 level), driven mainly by video demands. Figure Fig7 clearly shows this trend.

Fig8. Annual Mobile Data Traffics Growth in 2010 – 2018 Period (in Exabytes)

Undoubtedly, only LTE can meet this dramatic increasing data demands. According to GSA,

currently 521 LTE networks are commercially launched globally, and this number will rise to 560 by

the end of 2016.

There were 1.45 billion LTE subscriptions by 2016Q2.In addition 6,504 LTE commercial devices

were available in October 2016 (GSA Report “Status of LTE Eco-system”, 10-10-2016). It includes

all frequency bands and carriers bandwidth variants, powered by around 502 terminals suppliers,

as per GSA’s statistics. Among that total number of LTE terminals ~500 of them support APT700

Band 28.

With large countries such as Australia, Brazil, Japan or Mexico and now Europe working on

APT700 band for commercial LTE services it is expected that the number of LTE terminals

supporting APT700 will greatly increase in coming months. This should be even boosted with new

allocations of APT700 band 28 in several countries in 2017.

4 Interference Analysis between APT700 and

Legacy Systems

APT700 has to co-exist with other neighboring radio systems (from 3GPP or from other industries).

Several scenarios need to be considered:

APT700 and TV broadcasting services (below 694MHz): In 2011 APT has already

published a report to address possible solutions to avoid such interferences. For more

details please refer to the following APT document (APT/AWF/REP-24, [09-2011]):

http://www.apt.int/sites/default/files/Upload-files/AWG/APT-AWG-REP-24_APT_Report_6

98-806_Band_Implementation_UHF.pdf and ECC/DEC/(15)01 & EC Decision (EU)

2016/687

APT700 and other 3GPP systems working on E-850MHz band: Normally there is a

guard band of (at least) 4MHz (803-807MHz).

Lower Duplexer APT700 and DD800MHz (band 20): Normally there is a guard band of

3MHz (788-791MHz).

APT700 and public safety systems: There are on-going studies to assign radio

spectrum for public safety services next to APT700 band 28 and band 68. Therefore it is

necessary to address possible solutions for removing interference with commercial

http://www.apt.int/sites/default/files/Upload-files/AWG/APT-AWG-REP-24_APT_Report_698-806_Band_Implementation_UHF.pdf

http://www.apt.int/sites/default/files/Upload-files/AWG/APT-AWG-REP-24_APT_Report_698-806_Band_Implementation_UHF.pdf



APT700 networks when defining these options for public safety systems (on-going works).

APT700 and US700: There will be few cases where 2 neighboring countries will use

different 700MHz bands (e.g. Mexico and USA, Bolivia and its neighboring LATAM

countries). An early study conducted by Mexico Cofetel (published in 09-2012) has

analyzed possible solutions to avoid interferences at the border between Mexico and USA

when using different 700MHz plans. Please refer to the following link for more details:

http://www.cft.gob.mx:8080/portal/wp-content/uploads/2012/10/06-ANEXO-Convivencia-f

rontera1.pdf

Since the spectrums used for DTV, iDEN, DD800 and 850MHz is adjacent to APT700 frequency

bands, when operators plan to deploy LTE @APT700, the interference issue must be carefully

taken into consideration and handled properly.

Fig10. Co-existence of APT700 and Other Systems (Cellular and TV Broadcasting)

There are 6 interference scenarios to be analyzed. For each scenario, the main interferences

including spurious interference and blocking interference are analyzed.

Scenarios Interference Case

Scenario 1 DTV transmitter below 694MHz -> APT700 BS UL (Note: different countries and areas may deploy DTV spectrum > 694MHz, in

considering DTV spectrum < 694MHz)

Scenario 2 APT700 BS DL -> DTV Receiver

Scenario 3 APT700 LTE Device (UL) -> DTV Receiver

Scenario 4 DTV Transmitter below 694MHz -> APT700 LTE Device (UL)

Scenario 5 APT700 BS DL -> iDEN UL

Scenario 6 APT700 BS DL -> 850MHz UL

Tab8: APT700 & Other Bands Interference Scenarios List

http://www.cft.gob.mx:8080/portal/wp-content/uploads/2012/10/06-ANEXO-Convivencia-frontera1.pdf



In addition there is a need to address following 2 interference cases:

APT700 and US700 bands interference: e.g. USA and Mexico, Bolivia and its neighboring

countries (Region 2)

APT700 and DD800: e.g. countries in Region 1

The 3GPP standard is already complied to all requests to protect broadcasting services from APT,

Middle East, American and Europe countries. Thus, the same 3GPP terminal could be used over

all countries which are adopted the band 28.

4.1 APT700 Interference Mitigation Analysis with DTV Services

The band below APT700 is mostly dedicated to TV broadcasting in the four global variants (ATSC,

DVB-T(2), DTMB and ISDB-T). These are then supported by UHF channels with a country specific

raster (difference between neighboring channels in a frequency band) of 6, 7 or 8MHz.

The D-TV transmitters could interfere with the LTE FDD base station receivers, particularly given

the very high power that D-TV transmitters can emit.

Here one considers the worst case which is DTV channel neighboring to APT700 uplink to analyze

the interference as the following figure shows.

Fig11. Interference between DTV Channel and APT700 Uplink



Scenario 1: DTV transmitter below 694MHz -> APT700 BS Uplink

Main assumptions being considered are as follows (some of them from Japan interference study

between APT700 and DTV):

The power of the DTV transmitter: 3kW (64.8dBm)

DTV channel, effective BW 5.6MHz

Spurious level: -50dBc

Propagation model: Free space

APT700 BW: 5MHz

Two scenarios are taken into consideration based on the distance between DTV transmitter and

APT700 eNodeB: co-existence and co-site. When co-existence, 2 sub-cases are proposed, one is

DTV transmitter with 100 meters antenna height setup, and the other one is with 20 meters

antenna height setup. The minimum path losses between DTV TX port and LTE BTS RX port being

considered in those 2 scenarios are listed in the following table.

Site Distance: 100~3000 meters between DTV Transmitter and APT700 Base Station when Co-existence

Path loss (dB)

DTV & eNodeB co-existence (height of TV antenna: 100m) >73

DTV & eNodeB co-existence (height of TV antenna: 20m) >47 (higher

interference!)

DTV & eNodeB co-site 90

Tab9: APT700 & DTV Interference (from Japan interference study between APT700 and DTV)

1) Spurious Interference

The spurious emission of the DTV transmitter is:

64.8dBm / 5.6MHz - 50dBc – 10 * log(5.6) = 7.3dBm / MHz

According to background noise calculation (assume NF=2dB), the accepted spurious interference

of APT700 BTS Rx by DTV Tx is -118dBm/MHz when its noise rises 1dB.

Tab10: APT700 & DTV Interference Scenarios (Scenarios from Japan interference Study)

Obviously, in order to assure APT700 uplink sensitivity, additional filter needs to be installed in the

DTV side. Note that some parameters used for this analysis might not be the same as the real

situation. For instance, the spurious emission level of DTV transmitter might be better than -50dBc,

so the additional isolation being required could be less.

2) Blocking Interference

According to Huawei typical APT700 RF module test results, the accepted blocking interference by

DTV DL is 0dBm / 5MHz.

Scenarios

DTV & eNodeB co-site, 3KW 64.8 0 90 -25.2

Tab11: APT700 & DTV Interference (Scenarios from Japan interference Study)

Form the table above, when DTV transmitter tower co-exists with APT700 BTS, and the height of

DTV transmitter tower is 20 meters, in this case, additional 17.8dB isolation is required.

The out-band interference to APT700 receiver is decreasing when the spectrum used for DTV is

becoming far away from APT700 band.



Scenario 2: APT700 BS Downlink -> DTV Receiver

Based on the accepted spurious emission and blocking interference of Japan’s DTV receiver, the

spurious emission from the TX port of APT700 base station should not affect DTV receiver, but the

blocking interference by BTS can influence DTV receiver, hence additional filter needs to be

installed in DTV receiver. Whether the filter needs to be installed on the DTV receiver, it depends

on the anti-blocking performance of the DTV receiver.

Scenario 3: APT700 LTE Device (Uplink) -> DTV Receiver

This analysis refers field tests of interference between LTE APT 700 MHz and Digital TV (DTV)

systems released by ANATEL (Brazilian Telecommunications Agency). The conclusion is as

follows.

In the case of interference caused by terminal uplink into DTV receiver with passive indoor antenna,

test results show that filters can solve interference problems considering a combination of factors,

such as:

a) DTV reception signal close to the threshold at neighboring TV channel or at channel in which

image frequency coincides with LTE frequency

b) LTE device with maximum output power (at LTE cell edge)

c) The distance between the mobile terminal and the receiving antenna may be necessary due to

unwanted emissions from the terminal and/or emissions in the frequency range of LTE terminal.

The relaxation of any of the conditions above reduces the chances of occurrence of such

interference.

In case of DTV receiver with external antenna, it has better DTV reception signal and reduce the

potential interference from LTE uplink.

Scenario 4: DTV Transmitter below 694 MHz -> APT700 LTE Uplink (UE)

This analysis refers field tests of interference between LTE APT700 and Digital TV (DTV) systems

released by ANATEL (Brazilian Telecommunications Agency). The assessment was based on



changes of throughput, modulation and error correction code. There is interference only in case of

high values, which is out of regular practical conditions. In the case of DTV interference towards

LTE device, the mitigation technique is just the separation from interfering source.

4.2 APT700 Interference Mitigation Analysis with iDEN Systems

The spectrum used for iDEN system is close to APT700 DL as the following figure shows, so here

we analyze interferences from APT700 downlink to iDEN uplink.

Fig12. Need for Interference Mitigation from APT700 Downlink to iDEN Uplink

Scenario 5: APT700 BS Downlink -> iDEN Uplink


Assumptions are as follows:

iDEN antenna gain: 17dBi

LTE700M antenna gain: 17dBi

The down tilt of iDEN antenna: 4°

The down tilt of LTE700M antenna: 4°

The gain reduction when iDEN antenna tilt set to 4°: 3dB

The gain reduction when LTE700M antenna tilt set to 4°: 3dB

The feeder loss of the iDEN system: 1dB

The feeder loss of the LTE700M system: 1dB

LTE APT700 BW: 5MHz, 40W TOC

Propagation model: Free space

Two scenarios are taken into consideration based on the distance between the iDEN site and

APT700 base station: co-existence and co-site.



a) Co-existence

The isolation level between LTE700M TX port and iDEN RX port varies with the distance as the

following table shows when iDEN site co-exists with APT700 base station.

Source: Huawei calculation based on propagation model of free space

Tab12: Isolation Level between APT700 and iDEN System (Co-existence Scenario)

The output power of APT700 base station is 46dBm (40W), based on Huawei typical APT700 RF

module tests.

The spurious level of iDEN uplink is -68dBm/25kHz.

The sensitivity requirement of iDEN system is -115dBm/25kHz.

Also the isolation required is -68-(-115) = 47dB

According to Tab12, when the distance is more than 200 meters, the path loss can assure the

isolation requirement between iDEN site and APT700 base station.



b) Co-site

When APT700 base station is co-sited with iDEN site, there are 2 types of antenna installation

methods, parallel and serial (vertical) installation. The way they are installed and the

corresponding isolation level being achieved are listed in following tables.

Tab14: Vertical Antenna Installation (APT700 & iDEN)

As it is introduced in the previous section, the isolation requirement is 47dB, so when the iDEN

antenna is installed in parallel with the antenna of APT700 base station, if the distance between

these 2 antennas is more than 2 meters, there is no need for any additional filter.

When these 2 antennas are installed serially, no additional filter is needed.




The requirement of out-band blocking index of iDEN is -20dBm, and LTE700M output power is

46dBm / 5MHz, so the total isolation requirement is 46-(-20) = 66dB

Tab15: Isolation between APT700 & iDEN Systems

According to the Tab15, when the distance between APT700 base station and iDEN site is more

than 1500m, no additional filter is required. Otherwise, additional filter with proper isolation level is

needed.

When APT700 base station is co-sited with iDEN radio equipment, and if these 2 antennas are

installed serially with 3 meters distance, then there is no need to setup additional filter. Otherwise

additional filter with proper isolation level is required.

4.3 APT700 Interference Mitigation with 850MHz System

The following chart indicates the co-existence between APT700 and 850MHz bands.



Fig13. APT700 & 850MHz Bands Co-existence

Here E-850MHz is not considered. If there is a need to address E-850MHz then the interference

study should be handled case by case.

Scenario 6: APT700 BS Downlink -> 850MHz Uplink


Assumptions:

APT700: 2*40W (46dBm), Downlink Block of 793～803MHz

850MHz: Uplink Block of 824～829MHz

The down tilt of 850MHz site antenna: 4°

The down tilt of LTE700M antenna: 4°

Note: The isolation between LTE700M TX port and 850M RX port refers to the previous section of

“APT700 Interference Mitigation Analysis with iDEN Systems”.

The accepted spurious emission of 850MHz is -118dBm / MHz when its noise rises 1dB.

Considering the transmit power of APT700 (46dBm / 5MHz), based on Huawei typical APT700 RF

module tests, the spurious level of 850M UL is -91dBm/MHz, as well as 2dB feeder loss, so

eventually, around 25dB spurious emission needs to be handled.

When APT700 site needs to co-exist with 850MHz site with 100 meters distance, the spatial

isolation can achieve 40dB, which already meets the isolation requirement.

When APT700 site is co-sited with 850MHz BTS site, according to antenna isolation table, both

parallel and serial installation of two antennas can assure the interference suppression

requirement.

Hence, there is no need to install additional filter on APT700 site.




For Huawei typical 850MHz RF Unit, the tested accepted blocking interference of 850MHz is

16dBm@803MHz, considering the transmitter power of APT700 (46dBm) and the feeder loss

(2dB), the isolation requirement is 28dB.

Based on above conditions, when APT700 site needs to co-exist with 850MHz site with 100m

distance, the spatial isolation can achieve 40dB, which already meets the isolation requirement.

When APT700 site is co-sited with 850MHz BTS, according to antenna isolation table, both parallel

and serial installation of 2 antennas can assure the interference suppression requirement.

Hence, there is no need to install additional filter on 850M site.

4.4 APT700 Interference Analysis with DD800 Systems

It is important to notice that both frequency bands have neighboring downlink and they need to

comply with the same technical set of parameters. Thus, basically, there is no interference

between both frequency bands.

Nevertheless, if one wants to use both frequency bands with the same antenna (the same operator

has both neighboring spectrum blocks), then there are some inter-modulation requirements and

some combinations to mitigate interferences internally within the MNO network. Thus, it is more an

implementation related issue.

Here the suggestion is to analyze case by case for different deployment of spectrum blocks for the

same operator (between APT700 lower duplexer and DD800) and antenna site setup.

4.5 APT700 Interference Analysis with US700 Systems

This case is limited to few neighboring countries allocating APT700 in one side of the border and

US700 on the other side of the border. They are:

Mexico and USA

Bolivia and its neighboring countries



Mexico has conducted a study about the interference mitigation between US700 and APT700

bands. It is available via:

co_230912.pdf

5 Conclusions

With the increasing capacity and coverage needs to address the MBB/LTE development, APT700

band is well positioned to enhance the LTE adoption. Since early 2010 under the leadership of the

APT organization and with the combined standardization effort of ITU and 3GPP, APT700 has

become a major spectrum band for LTE services. Key standardization milestones are:

In 2010 APT has officially introduced its 700MHz band plan to ITU and it has been ratified

for Regions 2 and 3 in 2011.

In 2012 3GPP has officially included APT700 (band 28 for FDD mode and band 44 for TDD

mode) into 3GPP R11.

During WRC-12 ITU has allocated for mobile service and has identified for IMT the

694-790MHz band (APT700 Lower Duplexer band 28 + band 68) in Region 1. That means

all regions around the world (with the exception of about 3 America countries) has adopted

APT700 band plan. It represents a market exceeding 4 Billion people.

3GPP has defined 2 options for APT700 introducing FDD mode (Band 28) and TDD mode

(Band 44).

As of today most of countries are committed to support APT700 FDD mode. This document mainly

discusses the APT700 Band 28 which provide a bandwidth of 2x45MHz for countries in Regions 2

and 3 (in Region 1 it is set to 2x30MHz as APT700 Lower Duplexer and band 68 it is 698-728 UP &

753-783MHz DL. The 698-703 & 753-758MHz can be used for specific services PPDR. The

733-736 & 788-791MHz can be used for specific services e.g. PPDR…).

The APT700 band plan allows greater spectrum planning flexibility, giving the possibility to adjust

channel sizes to necessities of particular market and country by allocating blocks ranging from

2x5MHz up to 2x20MHz.

It is important to notice that 14 countries have already allocating APT700 blocks to operators and a

http://www.coleago.co.uk/fileadmin/user_upload/Downloads/APT_Band_Plan_Adopted_by_Mexico_230912.pdf

http://www.coleago.co.uk/fileadmin/user_upload/Downloads/APT_Band_Plan_Adopted_by_Mexico_230912.pdf



large proportion of these operators (30+%) has been granted a block of 2x15MHz at least.

Currently 26 operators have already enhanced their LTE networks in adding APT700 band. For

example major operators in Australia, Brazil, Chile, France and Japan already use APT700 Band

28 for commercial services. In coming 12 to 18 months it is expected that APT700 will be auctioned

in several additional countries.

APT700 brings key benefits to operators including:

LTE700MHz can strengthen indoor city coverage / wall penetration and push MBB

coverage to rural areas in a cost-efficiently manner. A LTE 700MHz base station has at

least 2-3 times better coverage then a base station using LTE1800MHz base station

coverage area, and can greatly optimize the CAPEX/OPEX of mobile operators.

APT700MHz band plan will improve the mass market and the availability of a large chose

of terminals.

Improve the roaming.

Easy deployment because the 700MHz is complied to the capillarity of networks already

deployed for the 900MHz or 1800MHz or 2100MHz frequency bands.

APT700MHz is powerful for enhancing cell edge coverage for in-building scenarios. It can

greatly benefit all LTE services types such as video and VoLTE.

On average and based on current APT700 allocations in several countries it can provide

blocks of 10MHz to 15MHz to operators. It is a significant advantage to develop MBB.

APT700 can be easily combined with other bands to provide LTE-Advanced carrier

aggregation services. It is already in used by 10+ operators (worldwide).

APT700 is a perfect option to leverage new services such as NB-IoT due to its significant

propagation advantages.

APT700 ecosystem as a whole has already reached a significant market size. All major chipset

vendors have already released products supporting APT700 frequency band since 2013, and

there are ~500 LTE commercial terminals supporting APT700 as of today. In addition APT700 can

be aggregated to other band to boost the end-users throughput. Commercial terminals supporting

CA scenarios in using APT700 are commercially available since 2015.

Finally the wireless industry has over passed possible interference issues between APT700 and

other legacy systems (whatever they are, cellular or TV broadcasting services). There is a

consistent set of proposals and guidances from standardization bodies, regulators, operators and

vendors to mitigate interferences to or from APT700 band. Such rules have been already applied in

several countries where APT700 band is used for commercial LTE services. Of course it is

assumed here that local TRAs with relevant Government offices have successfully implemented a

digital switchover roadmap to free the APT700 spectrum for mobile communications.

The 700 MHz band would be made available for wireless broadband in Europe by 2020. According to the Council position, EU countries must reassign the 700 MHz band (694-790 MHz) to wireless broadband services under harmonised technical conditions by 30 June 2020. If they are unable to do this they may decide, for duly justified reasons, to delay the availability of the band by up to two years. Member states must adopt a 'national roadmap' by 30 June 2018, setting out
