Business requirements– Enhance, within the buildings, the existing macro radio coverage– Complement the existing radio coverage by providing access to mobile network

infrastructures via ADSL connectivity (where no macro coverage is available, or to gain benefit from the ADSL access for mobile TV services for instance)

– Those requirements are applicable to both business market and mass marketCurrent Solutions

– Technical solution based on micro repeaters, optical/RF repeaters, cat5/6 cables, BTS or Node R implemented depending on business requirements and associated

– Deployment of Femto solutions FUT on SME market on going, commercial launch expected mid 2010

– Implementation of I-Wlan like solutions to access TV services POC performed early 2010Possible commercial launch by the end of 2010 (Studies on-going)

Tools - integration required for commercial launch– Wanda (Indoor design tool) tested for 2G/3G indoor design and used for Wifi deployment– Actix / Nemo for survey

Needs– Repeaters compatible with UMTS 900 implementation– Femto solution providing a satisfactory level of service within the various customer

Orange Moldova

Is the current catalogue of solutions adequate ?We are under investigation about low cost indoor solutions like micro repeater for different scenarios:

> 2G> 3G> 2G/3G

Local constraints:

RAN - GSM/DCS/UMTS

Spectrum distribution:- GSM900 - two bands: 17+ 42 channels- DCS1800 - one band: 89 channels- UMTS2100 - one band: three carriers

Cell type:- Single GSM900- Single DCS1800- Concentric Multiband GSM900/1800- UMTS2100: R99/HSPA


Orange Moldova

Is the current catalogue of solutions adequate ?- Distributed Antenna Systems (DAS) ->OMD: it is expensive solution and could not used

for all MKT requests - 2G or 3G Repeater -> OMD: priority1 , it is necessary to investigate optimal

configuration (2G, 3G or 2G/3G) , OMD restriction 900 MHz spectrum distribution-(GSM900 - two bands: 17+ 42 channels, DCS1800 - one band: 89 channels,

UMTS2100 - one band: three carriers). No CSC for 2G repeaters. - Pico-cells -> OMD: FT group has not validated any Huawei 3G Picocell solution? Any

plans to do so? We could be interested in this. - IP Access 2G “nano-cell” -> OMD: What about 3G? - Unlicensed Mobile Access (UMA) -> OMD: No interest - Huawei “Flybox” – bringing indoor WiFi + fixed voice from the available outdoor

HSxPA -> OMD: we have this already solution but sales are very low due to relatively expensive user device for Moldovan market (without subsidy)

- WLAN Router + ADSL -> OMD: to be investigated but marketing is not very keen since this is offered by our competitors

- I-WLAN a life saver for wireless indoor high speed ? -> OMD: under investigation (conf call with Bridgewater) but expected to have limited scope in Moldova

- SME Access Points - high power 3G femto. -> OMD: expensive solution for small networks , business case for OMD under analysis.

- 3G Femtocell-> OMD: expensive solution for small networks , business case for OMD under analysis


Orange Moldova

NB: For DAS, this is currently mainly passive DAS, there are no group-recommended RF/Fibre solutions although these have of course been used by individual MCOs. Is RF/Fibe now important to MCOs ->OMD: we are interested in 3G side for applications in very high data traffic areas where users are highly concentrated (such as student residences) where no other solution is applicable. Is there anything else that you think we should be working on ? -> OMD : To have a possibility to deploy indoor solution not only on large networks but also on small networks ( ex. Femto CSC- no buisnes case for small networks deployment) To pay as you grow.Could you indicate your priorities / opinions ? ->OMD: Our priorities is to have an available alternative, low cost indoor solution ( coverage, capacity or both)ex. 2G. 3G and 2G/3G indoor repeater.

Orange Romania

Tools– TEMS Pocket/TEMS Investigation used for coverage assessment and fine tuning after installation of

indoor systems– At this point we do not use specific tools for the indoor design process– Quality indicators for donor cells are carefully monitored for severe degradations that can be linked to

an installed repeater

Local Initiatives– 130 DAS shared with VDF, on a reciprocity basis– New small repeaters deployment procedure.

Repeaters deployment process is fully outsourced and managed via ticketing tool (Remedy ARS) Based on the information from complaints, radio team will issue an repeaters request HBT (half band ticket); if positive (after survey) SLA repeaters installation is 10 working daysVery successful; fast responsiveness to customer complaints; Corporate Department extremely satisfied

2010 Needs– Micro repeaters – 1,000 2G, 40 3G (Residential, SME, Corporate)– Medium/High Power – 60 2G, 10 2G/3G (Public, SME, Corporate)– Preparation for deployment of large active indoor coverage systems using FO distribution


Orange Romania

Femtocells

– Femtocell is considered an low cost indoor coverage solution SoHO/SME and Corporate Customers.– The Business Case is based on Open ISP approach trying to solve coverage issues (repeaters

substitution/alternative and indoor coverage improvement programs)– Validation was performed for Huawei uBro 1.5 in Romania (on field) and in France (on lab). The

validation was ended in Jan.– Currently we are running the FUT with 25 business customers using SME AP (100 mW power) on the

collocated carrier used for voice in macro (F1-R99 macro, F2- HSDPA, F1-femto). – Technical conclusions showed that special care should be taken to avoid interference between macro

and femto and also the internet line quality needs to be in line for the QoS of femtocell service.

Our next plans are related to close the negotiations with Huawei and plan T2 for the femtocellvery soon.

Topics for discussion

Usage of GSM1800 vs. GSM900 frequency bands for in-building installations

Optical repeater systems:

– size of building/project when considering optical system

– who owns the site (operator / third party / vendor)

– who plans and builds and maintain the site (operator / third party / vendor)

– vendor of equipment (Andrew/Powerwave/..)

Low cost solution for small installations


In-Building Steerco – meeting #1MCO Status Report – Orange UK

Alessandro Bovone Access Network Design – Radio Systems Manager


Orange UK

Current Solutions– In OUK at the present we have some live solutions for our customer:

UMA solution for residential.Pico-BTS solution by RadioFrame/NSN for SME / Corporate.Special projects :

On-train repeater solution for Virgin and Pendolino train shared with others UK operators.Single passive antenna with attenuation (usually in Orange Shops)Distributed antenna systems (commonly in corporate offices and hotels)Active antenna systems, used in places like Excel & Heathrow T5

– How many ?UMA solution is based on E// HSBC at Rel4 SW level. OUK has deployed 2 symmetric systems in Bristol and Liverpool to support respectively UK south traffic and UK centre/north traffic. At the present OUK has upgraded the 2 HBSC to cope with the traffic growth forecast until June/July 2010 (240k simultaneously registered subs by end of 2010). At the present we are carrying circa 70k simultaneously registered subs.Pico-BTS: at the present deployed 120 pico-BTS deployed to serve SME and corporate customer.Special projects: hundreds lots.

Tools– No specific tools are in use for design or survey or performance analysis of in-building solution in OUK.

For UMA raw counters from HBSC are collected and KPI produced for internal use.For pico-BTS the same counters and KPI for macro network are in use as the solution uses NSN BSC.


Orange UK

Local Initiatives– In January OUK marketing has re-launched UMA platform and since then we have seen

increase of customer using UMA from less than 20k up to 70k (ongoing).

– HW upgrade for capacity reason of E// UMA platform carried out in March (completed successfully).

– Additional HW upgrade for capacity reason for E// platform to cope with 2010 traffic growth forecast. (ongoing)

– Assessment of Low power repeater from different vendor such Nexitivity, RF Window (completed for the moment, expected to assess Nexitivity new product).

– NEC 3G Femto validation (just started design phase, possible trial in UK in Sept/Oct 2010 and launch planned for Apr 2011).

– Assessment/audit of ALU 3G femto solution with Group (ongoing).

– How to deal with E// end of life: may upgrade of E// UMA platform to Rel5 because end of support reached by Rel4 but in 2 years time end of life for the platform. (ongoing)

– National roaming on UMA. For now, testing and validation for now testing and validation will be limited to Cable & Wireless (C&W) MVNO and TMUK.


Orange UK

Local Initiatives– Emergency calling: OUK regulatory (OfCom) in response of EU is currently looking to

revise the General Condition 4 requirements in this area and that the new wording is worded more strongly than the old one as per abstract here below :Omissis… 5. Member States shall ensure that undertakings concerned make caller location information available free of charge to the authority handling emergency calls as soon as the call reaches that authority. This shall apply to all calls to the single European emergency call number "112". Member States may extend this obligation to cover calls to national emergency numbers. Competent regulatory authorities shall lay down criteria for the accuracy and reliability of the caller location information provided. (ongoing).

– Service monitoring and reporting for UMA: due to the gaps in service management for UMA before the re-launch, there isn't really a good service reporting function in place for UMA – for PAYG in particular – We are working to get a robust set of stats in place as soon as possible which will be generic to the system should we move to a new platform. (ongoing).


Orange UK

Future Needs– 2G pico-BTS or 2G femto-BTS.– 3G Low power repeater as Nextivity to support at least 3 carriers.– 3G femto solution.– HW/SW upgrade UMA platform or new UMA platform.– UMA soft client.

Is the current catalogue of solutions adequate?– No – low cost mass market solutions required

Summary of In-Building SolutionsWLAN Router + ADSL


Potential data-only solution for users with ADSL/WLANI-WLAN is a standard defined by 3GPP (Release 6).

– It provides a secured and controlled access to mobile operator’s data services through any WLAN access or even any IP access point.

– I-WLAN allows the reuse of existing Orange mobile data services’ platforms.

I-WLAN is still under studyCommercial trial is under study in FranceThe rationale of this technology is to decrease network costsThe main issue with this technology is that it is not yet adopted by device vendors

It is very good candidate for the offload of mobile networks.

Summary of In-Building Solutions - Conclusion


In-Building Steerco – meeting #1Femto and UMA position

Bertrand WAELSFrance Telecom NCPI/NAD/RAN


Femtocell at a glance. A hot topic definitely.Now and tomorrow… While UMA is stalling but not dead.

Femto Competition is fierce– Vodafone launched Alcatel Lucent based solution in UK for mass market– SFR launched NEC based solution in FR for mass market and now SME also– France Telecom so far the only one using “open mode”

No massive Femto adoption by mobile operators beyond the hype … so far– Entry cost is a barrier when addressing slow ramp up ( 2m€ with services)– Interference management state of the art is driving to dedicated carrier deployment– Technology was in learning phase – integration of chipsets– Standardization was not completed – open IuH

Tomorrow could be the ramp up of Femto– Sharing between operator is feasible – further studies to quantify the benefit– New chipsets and new interference management techniques announced– Experience on products – now on 2nd generation, end of year 3rd generation– IuH standard completed : opening architecture to third parties and paving the way for massive

deployments and competition.

UMA has not gained world wide traction– Few operators only. OPL and OSP stopping the service. OFR stalling– OUK experiencing huge customer base increase because of indoor coverage need.– There are opportunities with UMA on hotspots, UMA soft client.


Several actions on Femto are ongoing across FT Group that increase our experience and knowledge

Huawei and NEC Femto are currently in validation–Huawei

T6 green light on a preliminary version (UBRO 1.5) for business segment but not suitable for massive deployment.New version and equipment (UBRO 2.0 patch) will be validated upon availability June 2010( T6 end August )FUT running in Romania

–NECT6 green light on first generation ( APG2) with a bunch of restrictions ( no mobility, HSDPA capped at 1.6 mb/s /cell, … )FUT running in France since summer 2008 : numerous (un)stability issues) .Recovery plan ongoing with NEC on the APG2 and close follow up of APG3 delivery by NEC (T6 planned June 2010)

Since December 2009, Intensification of exchanges with non selected suppliers about their Femto solutions : industry is very active. Various solutions are on the market.

–Workshop with Alcatel-Lucent in December and March. Audit in April.–Meetings with Starent ( Cisco ) , Spider Cloud ( startup), Qualcomm ( chipsets ), ..

Group RFI is ongoing to formalize information collection about market and enablers of our competitors.–18 companies : 6 integrators, 12 access points suppliers–Enterprise & consumer deployment questions.–Sent 31MAR / answers 19APR / analysis 27MAY

Audit of Alcatel Lucent solution done in Nuremberg ( April 28-29)

“ non committed QoS, no monitoring, self install”Customers call upon issue or bad experience

CONSUMER SEGMENT

Tested and produced by FT“ committed QoS, monitored, installed by

Orange”Orange proactively detects malfunction,

dedicated broadband lineBUSINESS SEGMENT

Femto technical challenges depend on type of deployment. Further tests with SoHo are needed to conclude about large-scale deployment.

Closed mode - protect the Femto and QoS Open mode – reduce interference risk

(customer) pre-defined set of customers allowed to camp on the FemtoA limited dead zone area created at the coverage

boundary “shadow effect”Secure QoS level for authorised users – private

coverage

All customers allowed to camp on the cell.Mitigate the localised interference effect between

Femto and outdoor Number of users not manageable - raises the risk

of overload

Self installation – lowest cost but QoS risk in & out

Managed installation – mitigate uncertainties

Customer free to choose location : risk of increasing interference by “through the window effect”No installation cost

operator controls where the Femto is installed and allows multi-Femto installations with mobility

operator tests the coverageequipment is self-configuring

Until now, not tested high density deployment with many access points in a concentrated area. Preventing from experience of a “consumer alike deployment”


Based on studies and field experience, several Femto cell key learnings to date

End to end integration is essential to QoS– Open ISP mode ( not experienced) to be carefully addressed about commitment to our customer.– IP collection architecture to be compatible with Femto to Gateway connection.

Better to deploy several access point operating at lower power in same location : tailor the coverage.Inter Access Points mobility is required in such case.

– To manage indoor inter AP interferences– To give seamless customer experience in mobility.

Outdoor interferences are limited but real– Limited to few meters “in the street”– Can lead to drop call a “macro 3G user” if no successful handover to outdoor 2G layer.

Deployment on dedicated carrier is advised by all suppliers.– Luxuous spectrum usage not possible in most of our operations – Appropriate carriers allocations to be defined in each country.

Problems investigation can be very tricky – bullet proof procedures to establish when launching the service.

– Few counters available in massive deployments ( granularity )– Many factors influencing the experience : interferences, ADSL quality, enterprise network

integration, location of the AP, traffic load on the AP, …Femtos to be used for what they are designed for.

– Regular Femto which are Low capacity are not suited for high traffic area .So called “managed installation” is high cost but improve customer experience

– Mandatory when committing on QoS ( entreprises )– Dedicated ADSL line is securing bandwidth availability.– Good knowledge of Femto localizations help trouble shooting.

Femtos are adaptatives to their environment– Open ISP is possible – with caution– Auto configuration is available.


Femto interference: managed today with limitations, industry could improve within 18 months in the final product.

Interference is the blurred result of several competing signal levels in a given point at a given time on the same frequency (carrier). It can happen when Femto leaks outside home.Mechanisms exist to handover to the less interfered signalclosed-user group mode (private access) is increasing the probability of generating areas of interference. Open mode allows customers switching to best signal to escape interference.

If 3 carriersallowed ideal case would be allocating one carrier for Femto but too

expensive. A carrier is very expensive. some countries have 2 carriers onlyand need it for regular outdoor traffic of macro network.Not recommended: using same carriers for Femto and for outdoor macro network - not possible today. easiest to manage spectrum resource . Suppliers are exploring this scenariorecommended is sharing one carrier to preserve other for regularmacro outdoor traffic. Preserves performance on one carrier. Optimize capacity . Also applicable when having two carriers only

All suppliers are implementing interference management algorithmsbut nobody has so far demonstrated real carrier sharing in high density deployments.

End 2010 should be the arrival of increased capacity and advanced interference management (not demonstrated) thanks to new chipsets for integration in the Femtos.


New position about Femto application beyond SME applications. Actions are launched to confirm the need and the feasibility

Share one carrier with outdoor macro network and preserve one “pure” carrier for other outdoor macro application. Never dedicate one carrier to Femto.Launch further actions on the field– A high density deployment experimental area to verify interference mitigation algorithms

on full scale (on the field) – sponsorship required. (estimated cost : 210 k€ )– Launch a FUT for Soho to get feedback on customer experience and correlate technical

findings with it. ( not estimated yet) Deploy a country per country quantified ( #customers, price, revenues) Femto strategy based on local assets (broadband, Wi-Fi, smartphones penetration) and 3G indoor coveragesituation.

SMBs and SoHos markets – Prioritize first in candidate countries with a market size that guarantees a ROI to be

calculatedConsumer market : – complete an 3G indoor coverage survey on Orange footprint (selected countries) for voice

and data, as well as Consumer appetite– large-scale field trial for Consumer is mandatory before any launch decision (technology

and marketing learnings and validation)

UMA is used in France, UK and Poland(*). Some developments ongoing to extend handset availability. WiFi is preferred for Data offload. New UMA networks shouldn’t be deployed.

Ericsson equipment installed in OFR and OUK are end of support Eo2013– Negotiations ongoing with Ericsson to extend again the commitment– Hardware extensions are still possible

(*) Poland is using UMA but not promoting neither operating the system anymoreLimited choice of handsets with UMA.Currently we do not recommend new deployments of UMA in other countries.

Convergences between NEC Femto and Kineto UMA are proposed by NEC and Kineto but do not seem very effective in cost savings in regards with induced complexity.UMA Soft Client is currently developed by Kineto to allow UMA installation into any smartphone“outside the chipset” : flexibility for operator

– Until now only voice client developed on Android– Other devices under development– To NOT confuse with a “customer downloadable client” like Skype or others. We speak

about a operator customisation.

For very high throughputs and volumes, UMA is limited by its specification/ architecture.– WiFi is the preferred technology for huge data traffic ( offload). It is currently studied by NAD.
