Report ITU-R M.2078 (2006) presents the results of the calculation ofspectrum requirements for RAT Group 1 (pre-IMT, IMT-2000 and itsenhancements)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 behigher in order to account for packaging the spectrum (integer multiples of 40 MHz for RATG1)
How much additional spectrum is needed ?

http://www.ngmn.org/uploads/media/Spectrum_Requirements_for_the_Next_Generation_of_Mobile_Networks.pdf
Extrapolating from the ITUs forecast, in 2007 the NGMN Alliance determinedwhat the net spectrum requirement would be, based on existing allocations, ineach of the three ITU regions1:
Additional demand between 500-1000 MHz by 2020 depending on region

ITU
ITU is the leading United Nations agency for information and communication technologies.As the global focal point for governments and the private sector, ITU's role in helping the
world communicate spans 3 core sectors: Radiocommunication, Standardization and
Development. ITU is based in Geneva, Switzerland, and its membership includes 191
Member States and more than 700 Sector Members and Associates.
Radio Assembly (RA)
The Radio Assembly meets prior to each World Radio Conference to review the structure
of the ITU-R and to make decisions on any issues that have not been resolved by the ITU-
R Study Group(s) during the Study Period (between WRCs)
World Radio Conference (WRC)
World Radio Conferences review the global Radio Regulations (RRs). RRs define which
services and systems can use specified spectrum bands.

Different Technologies influence Spectrum
IMT-2000 enhancements (e.g. LTE) and IMT-Advanced will bring
Additional channel bandwidths (1,6 / 2,5 / 10 / 15 / 20 / 40 / 100 MHz)
Resulting in variable bandwidths of (1,4 / 3,2 / 5 / 10 / 15 / 20 / 40 / 100 MHz) New modulation schemes (e.g. OFDMA)
MIMO antenna systems (e.g. 8x for BS and 4x for UE)
Relaying / multi-hop networks
For IMT-2000 different radio
interfaces / modulations are usedaround the world:
W-CDMA (e.g. Europe)
CDMA2000 (e.g. America)
TD-SCDMA (e.g. China)
OFDMA (e.g. USA)
resulting in regional differences in
spectrum allocation and licensing
Spectrum assignment will depend on technological and regional conditions

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 450470 MHz
72 MHz in the band 790862 MHz in Region 1 (EU, Africa) and 3 (Asia). Region 2
(Americas) and 9 Asian countries allocated 108 MHz in the band 698806 MHz.100 MHz 2.32.4 GHz band
200 MHz 3.43.6 GHz band: no global allocation, but accepted by many countries withsome 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)

Agenda Item 1.5 "to consider worldwide/regional harmonization ofspectrum 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 ofsharing studies between the mobile service and other services in theband 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 towardsWRC-15 to review the spectrumavailability for IMT: New studies (ITU-RM.2034) on the spectrum requirements
and additional allocations to the mobileservice for broadband systems includingIMT.This request is based on the calculatedincrease in mobile traffic (mainly data),which exceeds M.2072 (WRC-07) figuresby a factor of >5 already today.

WRC-12 resolutions
Various resolution have been approved by WRC-12
2 resolutions relating to IMT/mobile have been approved:
Res. COM 5/10: Use of the frequency band 694-790 MHz by the mobile, except
aeronautical mobile, service in Region 1 and related studies
to allocate the frequency band 694-790 MHz in Region 1 to the mobile, except
aeronautical mobile, service on a co-primary basis with other services to which
this band is allocated on a primary basis and to identify it for IMT; that the allocation is effective immediately after WRC 15;
Res. COM 6/8: Studies on frequency-related matters on International Mobile
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 forharmonization;
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;

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 ResolutionCOM6/8 (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;

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 iscurrently still used by broadcasting
applications
US was first to auction spectrum in
these bands (03/2008)

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.

WRC-07 was a major milestone for the
spectrum assignment for IMT systems
Spectrum requirements for IMT / IMT-Advancedhave been defined
Two IMT-Advanced radio interface technologies
have been approved
WRC-12 agreed on two new agenda items - tostudy Digital Dividend 2 and analyse existingIMT spectrum most possibly leading to new
conclusions / allocations at WRC-15
Multi-regional operators have to manage theirspectrum very carefully, depending on theregional markets
