Report ITU-R M.2078 (2006) presents the results of the calculation of spectrum requirements for RAT Group 1 (pre-IMT, IMT-2000 and its enhancements) and RAT Group 2 (IMT-Advanced) in 2010, 2015 and 2020.
Remark: RAT Group 3: Existing radio LANs and their enhancements
RAT Group 4: Digital mobile broadcasting systems and their enhancements
NOTE: When more than one network is present in a country, the total spectrum requirement may be
higher in order to account for packaging the spectrum (integer multiples of 40 MHz for RATG1)
How much additional spectrum is needed ?

3 major results in relation to Spectrum for IMT
17.04.2012 Slide 10
Under AI 1.4 globally harmonized spectrum was identified for use by IMT. In addition
to the existing 2G / 3G spectrum, various additional bands were allocated resulting in
392 MHz (EU, Africa, Asia) / 428 MHz (Americas, CHN, KOR, IND, JPN, NZL, a.o.):
20 MHz in the band 450−470 MHz
72 MHz in the band 790−862 MHz in Region 1 (EU, Africa) and 3 (Asia). Region 2
(Americas) and 9 Asian countries allocated 108 MHz in the band 698−806 MHz.
100 MHz 2.3−2.4 GHz band
200 MHz 3.4−3.6 GHz band: no global allocation, but accepted by many countries with
some obligations (e.g. cross-border deployment and power limitations)
Remark: This spectrum will not be available immediately, but become available following further
collaborative work on international, regional and national level (e.g. digital dividend in EU >2012-15)

WRC-12 RESOLUTION [COM6/7] (WRC-07)
Agenda Item 1.5
• "to consider worldwide/regional harmonization of spectrum for electronic news gathering
(ENG), taking into account the results of ITU-R studies“ [COM6/5] (WRC-07)
Agenda Item 1.17
• to consider results of sharing studies between the mobile service and other services in the
band 790-862 MHz in Regions 1 and 3, in accordance with Resolution [COM4/13] (WRC-
07), to ensure the adequate protection of services to which this frequency band is
allocated, and take appropriate action;
Agenda Item 8.2
• to recommend items for inclusion in the agenda for the next WRC [COM6/22] (WRC-07)
Agenda WRC-12
Remark AI 8.2 should include a new AI towards WRC-15 to review the spectrum availability for IMT: New studies (ITU-R M.2034) on the spectrum requirements and additional allocations to the mobile service for broadband systems including IMT. This request is based on the calculated increase in mobile traffic (mainly data), which exceeds M.2072 (WRC-07) figures by a factor of >5 already today.

Telecommunications and other terrestrial mobile broadband applications
• to study additional spectrum requirements, taking into account …………
• to study potential candidate frequency bands, taking into account the results of
the studies under resolves 1, protection of existing services and the need for
harmonization;
• studies referred to in resolves 2 include sharing and compatibility studies with
services already having allocations in the potential candidate bands and in
adjacent bands, as appropriate, taking into account the current and planned
use of these bands by the existing services, as well as the applicable studies
already performed in ITU-R;
17.04.2012 Slide 14
WRC-15 agenda
WRC-15 agenda is based on RESOLUTION [COM6/6] (WRC-12)
• 18 new agenda items have been approved
• Amongst them, 2 agenda items in relation to IMT/mobile have been approved:
• Agenda Item 1.1 on additional spectrum for IMT: to consider additional
spectrum allocations to the mobile service on a primary basis and identification
of additional frequency bands for International Mobile Telecommunications
(IMT) and related regulatory provisions, to facilitate the development of
terrestrial mobile broadband applications, in accordance with Resolution
COM6/8 (WRC 12);
• Agenda item 1.2 on UHF spectrum: to examine the results of ITU R studies, in
accordance with Resolution COM5/10 (WRC 12), on the use of the frequency
band 69x(4) -790 MHz by the mobile, except aeronautical mobile, service in
Region 1 and take the appropriate measures;

ITU-R “JTG 4-5-6-7” and supporting fora
A joint task group (JTG 4-5-6-7) has been established to work on AI 1.1 and AI 1.2 • Four ITU-R study groups are involved in this work
• ToR have been approved [document CPM15-1/TEMP/5_rev]
• The affected SG/WP (e.g. WP5D) have been given tough deadlines for their contributions
• Technical and operational characteristics, protection requirements as well as spectrum
requirements are to be submitted to the JTG for AI 1.1 (31.07.13) and AI 1.2 (31.12.12)
• Thomas Ewers (BNetzA) has been confirmed as chairman
• Announcement of the establishment of JTG 4-5-6-7 [ITU-R CACE/564]
• Two meeting per year resulting in overall 6 meetings
• #1: 23.-27.7. (week after WP5D) #2: 21.-28.11. (week after WP5x block meetings & SG5)
Working Party 5D will be in charge of carrying out studies on
• the spectrum requirements for the mobile service, including suitable frequency ranges and
candidate bands (AI 1.1 and 1.2); a collaboration with Working Party 5A is expected;
• channeling arrangements for mobile, adapted to the frequency band <790 MHz and on
coexistence between the different channeling arrangements which have been implemented in
Region 1 above 790 MHz, as well as the possibility of further harmonization (AI 1.2)
ECC/CEPT • ECC CPG (04/2012) decided how to support JTG 4-5-6-7 from European perspective:
• CPG “PT D” is tasked with the responsibility (chaired by Didier Chauveau)
• Work of PT D will be supported by other CEPT for a (e.g. PT1)
• 1st meeting of PT D is scheduled adjacent to next PT1 meeting (wk 38, Norway)

Important spectrum issues UHF-Band
17.04.2012 Slide 18
Importance of UHF bands for IMT
Benefits
• To cover rural areas with IMT, spectrum in the bands 900, 1800/1900, 2100/2600 MHz
alone is only limited suited:
• 2100/2600: urban / capacity / carrier-bandwidth demand >20 MHz
• 900/1800: currently used by 2G and 3G in the future
• DD (800): better propagation conditions / larger cell-sizes / better indoor-coverage
• UHF band is now globally allocated for IMT
scale of economy for hardware / devices / roaming etc.
WRC-07 identified UHF spectrum for IMT - Current situation
• In various countries this spectrum is
currently still used by broadcasting
applications
• US was first to auction spectrum in
these bands (03/2008)
• Europe: DE, SWE, ES, ITA, FRA,
Switzerland, Portugal
Next to follow in Europe: AUT, UK
• Asia: ???

How to get spectrum for LTE / 4G ? LTE capability in the German spectrum landscape
17.04.2012 Slide 27
1. Purchase spectrum
• Auction: most expensive, best income for regulator
• Beauty contest: application with no guarantee of acceptance
Possible drawback: Roll-Out obligations (e.g. rural areas)
2. Spectrum Refarming
• Re-using existing spectrum with new technologies
• In most European countries spectrum refarming is possible (legacy issues ?)
• Possible bands: 900 / 1800 MHz UMTS/LTE or 2100 MHz LTE
Problem: legacy spectrum is not equally distributed amongst existing MNOs
3. Free-Up additional spectrum
• Try to find spectrum which is not (efficiently) used (e.g. <790 MHz or 3.6-3.8 GHz)
Problem: long lasting process via ITU WRC and current user will not be happy
4. National Roaming
• Use the existing network of one of your competitors and pay for the access
Problem: very expensive unless not mandated by regulator (e.g. France, Spain)
5. Network Sharing
6. Buy an appropriate competitor ;-)

WRC-12 agreed on two new agenda items - to
study “Digital Dividend 2” and analyse existing
IMT spectrum – most possibly leading to new
conclusions / allocations at WRC-15
Multi-regional operators have to manage their
spectrum very carefully, depending on the
regional markets
Conclusions

UHF Bandplan in US (698 – 806 MHz)
Region 2: UHF in the US
• 17.03.10: FCC published “Connecting America” (376 pages) to connect 100 Mio.
housholds with 100 Mbit/s til 2020 by also using 500 MHz spectrum
17.04.2012 Slide 41
Options for rest of region 2 except of US (e.g. Canada, LatAm)
UHF in rest of region 2
2x 50 MHz
• LatAm is in an early stage of the Digital Dividend / National consultations
ongoing
• Telefónica is supporting a full-FDD bandplan similar to region 3
17.04.2012 Slide 42
UHF in region 3
Decision(s) in Asia
• 698-806 MHz:
• AWG (APT Wireless Group) has agreed “harmonised 2x 45 MHz FDD bandplan”
plus optional TDD-only bandplan: (APT REPORT No. APT/AWF/REP-14 Edition: September 2010)
• China DD becomes available in 2015 no decision about TDD/FDD yet
• 790-862 MHz: The rest of region 3 will have to agree on 790-862 MHz arrangement
Certain likelihood for adopting the CEPT bandplan
