5. APT AWG 700 MHz Band Plan Development
Process and timeline
! March 2008 - Spectrum Working Group initiated study of the UHF Digital Dividend, with the aim of
developing a harmonized band plan
§ Direct result of WRC-07 decision to identify spectrum for IMT
! September 2010 - Finalized work on the new 700 MHz band plan(s)
§ APT Report 14: Harmonized Frequency Arrangements for the Band 698-806 MHz
§ Consensus Agreement
! September 2011 - Finalized work on 2nd Report providing guidance on mobile user equipment out-
of-band emission levels to facilitate co-existence with adjacent band broadcast TV services
§ APT Report 24: Implementation Issues Associated with Use of the Band 698 – 806 MHz by Mobile Services
! Process was deliberate
§ Developed over 2.5 year period with considerable technical study by industry and governments
§ Gathered views of APT members through information survey
§ Prepared interim report with candidate band plan proposals – up to eight
§ Focused technical studies on candidate band plans
§ Set up technical correspondence group to work between meetings and analyze proposals
§ Held technical seminars to further vet studies
! High degree of cooperation among industry stakeholders (governments, vendors, operators,
associations) was key 5

Report 14: Harmonized Frequency Arrangements for the Band 698-806 MHz*
! FDD band plan
§ 2 x 45 MHz from 703-748 / 758-803 MHz – likely to require dual duplexer implementation
§ Conventional duplex – minimizes harmonic interference into GNSS/GPS
§ Internal guardband from 698-703 MHz and 803-806 MHz – facilitates co-existence with other services

7. APT Work is Complete
Report 24: Implementation Issues Associated with Use of the Band 698 – 806 MHz
by Mobile Services*
! APT Report 24 provides guidance on UE out-of-band emission levels:
§ “Considering technical and economic factors associated with UE equipment, it was concluded that the
average out of band emissions of IMT UE, measured over the bandwidth of the applicable television
channel in the country of deployment, must not exceed -34 dBm/MHz below 694 MHz “
! No guidance in Report 24 on the UE out-of-band emission levels from 694 MHz to 698 MHz.
Instead, APT deferred any decision on this to the 3GPP standards development due to the
technological advances in filter technology.

8. ITU-R Work on APT 700 MHz Band Plan is Complete
! Band allocated to the mobile service many years ago
§ See Article 5 of the ITU Radio Regulations for Region 3
! APT AWG 700 MHz band plan(s) were liaised from APT to the ITU-R
! ITU-R incorporated the new frequency arrangements into the most recent version of ITU-R
Recommendation M.1036-4:
§ “Frequency arrangements for implementation of the terrestrial component of International Mobile
Telecommunications (IMT) in the bands identified for IMT in the Radio Regulations.”
§ M.1036-4 formally approved in March 2012

Band 28 (FDD 703-748 / 758 - 803 MHz)
! All CR’s (change requests) were agreed and work completed at RAN4 #63 meeting in Czech
Republic May 21-25, 2012

June 2012). Technical aspects:
§ The 36.101 CR is in R4-123624
§ For co-existence with DTV service in 694-698 MHz adjacent bands, specified out-of-band emission level of
- 26.2 dBm/6 MHz across 694-698 MHz and introduction of Network Signaled (NS) value
§ Equivalent value to that recommended by APT at 694 MHz in dBm/MHz (-34 dBm/MHz)
§ Japan national issues – will resolve internally
§ Self-band protection is defined at -32 dBm/MHz

18. Observations and Recommendations
! APT 700 MHz FDD band plan represents best opportunity for Asia Pac regional spectrum
harmonization
! Harmonized band plans deliver economies of scale which drive down device cost
! Opportunities for multi-regional harmonization
! APT 700 MHz FDD (full 2 x 45 MHz) potential for largest addressable market
! Design maximizes amount of usable spectrum for mobile services (2x45MHz) and is the most
efficient use of scarce and valuable spectrum resources
! Momentum on APT 700 MHz FDD band plan is strong and increasing
! Operation of APT 700 MHz FDD (Band 28) together with extended-850 MHz (Band 27), 850 MHz
(Band 5), 900 MHz (Band 8) provides a highly efficient use of spectrum resources below 1 GHz

19. Policy Support Needed From Governments
! Provide a roadmap with clear timelines for UHF Digital Dividend spectrum availability so that
interested stakeholders have the certainty needed to plan networks and investments
! Make policy decision to allocate 698-806 MHz spectrum to the mobile service at the national level
! Make policy decision to harmonize frequency usage with the APT 700 MHz 2 x 45 MHz band plan
! Accelerate transition from analog to digital broadcast TV services in 700 MHz band which will free
up the spectrum for its highest value use – mobile broadband
! Let industry stakeholders know how we can best support you in developing the regulatory and
spectrum policy frameworks
