10 Orange Restricted
Multi-connected worldis driven by mobile services
• 85% of mobile subscriptions will be for mobile broadband by 2020
• IMT-2020 is expected to enable a fully mobile and connected society and must provide significantly enhanced user experience, network performance and operation including energy & cost efficiency
• Enabling the IMT-2020 future requires identification of additional spectrum
Mobile Broadband growth
11 Orange Restricted
New spectrum requiredto answer the growing demand for mobile broadband
4G continues its rise globally• 1.29 bn 4G connections world-wide
(March 2016)• a two-fold increase in one year• In Europe:
- 180 million LTE customers (up 80% year on year), accounting for 17% of the mobile base (March 2016)
- 67 LTE-A networks launched by End May 2016
- Sweden is the European champion, with 44% of its base on 4G
Dramatic mobile traffic growth in 2020 • ITU-R Report M.2290 : increase by 44–80 times compared to the year 2011 • This trend is confirmed by actual mobile market figures, which indicate that previous
forecasts have underestimated the real market development

List of potential candidate bands for study during the preparatory processtowards WRC-19
• 24.25-27.5 GHz, 37-40.5 GHz, 42.5-43.5 GHz, 45.5-47 GHz, 47.2-50.2 GHz, 50.4-52.6 GHz, 66-76 GHz and 81-86 GHz, which have allocations to the mobile service on a primary basis
• 31.8-33.4 GHz, 40.5-42.5 GHz and 47-47.2 GHz, which may require additional allocations to the mobile service on a primary basis.
Studies are expected to be completed by mid-2019
Candidate bands for IMTunder WRC-19 Agenda Item 1.13
17 Orange Restricted
• A number of factors have to be taken into account when considering this band• the extent of current usage e.g. the 24.5-26.5GHz band quite heavily used for
fixed links, also operated by Orange• regional variations (including studies for HAPS in Region 2) • the need to consider protection of space science services (space-to-Earth) in
the 25.5-27 GHz• new MOBILE allocation on a primary basis would be required at WRC-19 for
Regions 1 and 2 for the band 24.25- 25.25 GHz
• The whole range (24.25 - 27.5 GHz) represents an attractive candidate band for 5G/IMT-2020 offering a wide bandwidth of 3.25 GHz
24.25-27.5 GHzmain issues
18 Orange Restricted
• Considering propagation conditions, the 24.25-27.5 GHz band represents an attractive candidate band for 5G/IMT-2020 within the studied range from 24.25 to 86 GHz• in spite of the complexity, due to different factors, including current usage
• The 27.5-29.5 GHz band might be possibly first 5G/IMT-2020 band in some countries outside Region 1 e.g. USA, Korea, Japan• as 5G/IMT-2020 may be able to operate across a significant ‘tuning range’ of
contiguous spectrum, thus deployment in the lower or higher part of the tuning range will depend on the actual availability of spectrum either on regional or national basis
24.25-27.5 GHzpossible tuning range up to 29.5 GHz
We believe that particular attention should be given to the 24.25-27.5GHz band,
due to a possible tuning range up to 29.5 GHz to benefit expected economies
of scale in the provision of globally harmonised 5G/IMT-2020 services
19 Orange Restricted
• There is a limited current usage in the 31.8-33.4 GHz band
• the whole range represents a good potential for identification for IMT and a consecutive refarming
• there was already an extensive support for this range at WRC-15
• new MOBILE allocation on a primary basis for the 31.8-33.4 GHz band would be required at WRC-19
31.8 - 33.4 GHzpossible refarming
The whole range (31.8-33.4 GHz), offering a wide bandwidth of 1.6 GHz
represents an attractive candidate band for 5G/IMT-2020
in spite of the lack of a mobile allocation
20 Orange Restricted
Other candidate bands considered under WRC-19 Agenda Item 1.13
37-40.5 GHz band : is already allocated to mobile and represents an option for 5G/IMT-2020 with a wide bandwidth of 3.5 GHz
40.5-42.5 GHz & 42.5-43.5 GHz bands : represent an interesting option with a wide bandwidth of 2 GHz or 3 GHz if the whole range is identified for IMT
37-40.5 GHz band : is already allocated to mobile and represents an option for 5G/IMT-2020 with a wide bandwidth of 3.5 GHz
45.5 - 47 GHz & 47- 47.2 GHz : represent an interesting option
47.2 - 50.2 GHz: offers quite large amount of spectrum and is of interest for 5G/IMT-2020 but is also studied for non GSO FSS use
50.4 - 52.6 GHz : is of interest for IMT but is also studied for non GSO FSS use
66 - 76 GHz & 81-86 GHz : represent good option offering large amount of spectrum for IMT
Further studies are needed for all candidate bands in CEPT and ITU-R
before any decision on prioritisation could be taken
21 Orange Restricted
Only the bands above 24 GHz are studied under WRC-19 AI 1.13
• 5G/IMT-2020 will also require new coverage spectrum to provide nationwide services in the bands below 6 GHz
• In particular, the 600 MHz band offers potential for future global harmonisation as it has been identified for IMT by WRC-15 in several major markets in Region 2 and 3
• Other bands, below 24 GHz, not listed under AI 1.13 are of interest for mobile industry and some Administrations
• The bands such as: 470-694 MHz, 5.925-8.5 GHz, 10-10.6 GHz and 21.4-22 GHz present a strong potential for 5G/IMT-2020, in particular for propagation reasons
Other possible candidate bandsnot studied under WRC-19 Agenda Item 1.13
It is proposed to further consider at least the 470-694 MHz and the 5.925-8.5 GHz
bands for 5G/IMT-2020 on a regional basis since they cannot be studied
in the framework of WRC-19 preparation

Conclusionon candidate bands under WRC-19 Agenda Item 1.13
We believe that further studies are needed for all candidate bands inCEPT and ITU-R before any decision on prioritisation could be taken
However considering propagation conditions within the studied range from 24.25 to 86 GHz and research achievements (including pre-trials)
• particular attention should be given to the 24.25-27.5GHz band, due to a possible tuning range up to 29.5 GHz
• to benefit economies of scale in the provision of 5G/IMT-2020 services

Analysis of candidate bands studied under WRC-19 AI 1.13
29 Orange Restricted
• 37 - 40.5 GHz• extensive use for fixed links below 39.5 GHz in some CEPT countries
• military use above 39.5 GHz
• FSS in the whole range
• space services in 37-38 GHz and 40-40.5 GHz.
However, the 37-40.5 GHz band is already allocated to mobile and should be further considered as it represents an option for 5G/IMT-2020 with a wide bandwidth of 3.5 GHz
37 – 40.5 GHzan option for 5G/IMT-2020 as already allocated to mobile
30 Orange Restricted
• 40.5 - 42.5 GHz• is used for few fixed links
• is also designated to MWS (Multimedia Wireless Systems) broadcasting, radio-astronomy and the fixed-satellite service
• use for broadcasting is very limited
• is allocated to mobile on a secondary basis thus new MOBILE allocation on a primary basis would be required at WRC-19
There is some potential to identify the whole range for IMT. The 40.5-42.5 GHz band represents an interesting option for 5G/IMT-2020 with a wide bandwidth of 2 GHz, which could be extended to 3 GHz if the whole range (40.5-42.5 GHz and 42.5-43.5 GHz) is identified for IMT.

31 Orange Restricted
• 42.5 - 43.5 GHz• is used mainly for fixed links or MWS • there may be satellite network filings in some countries• removal of the satellite allocation can be proposed, as it was already the case
at WRC-15 (CEPT proposal)• Radio astronomy should be protected, but sharing with the radio astronomy
service may be possible by the use of exclusion or coordination zones around specific observatories
• is already allocated to mobile on a global basis

China)represents an interesting option for 5G/IMT-2020 with 1.5 GHz bandwidth, with the potential for a larger contiguous bandwidth if linked with the following bands
• 47- 47.2 GHz • no mobile allocation in this band thus it would be required at WRC-19• is allocated world-wide to the amateur service; however the actual usage
seems to be very limitedoffers very limited amount of spectrum however may be of interest for IMT if the contiguous spectrum with the bands below and/or above, could be identified

defence satellite systems up to 74 GHz and the possible future fixed links
Represents a good option for 5G/IMT-2020 with a wide bandwidth of 10 GHz
50.4 - 52.6 GHz & 66 - 76 GHzcould offer quite large amount of spectrum for 5G/IMT-2020
