ITU’s mission is to enable the

growth andsustained development of telecommunications and

information networks, and to facilitate

universal accessso people everywhere can benefit

from the global information society.

World Radio Conferences, WRChttp://www.itu.int/ITU-R/index.asp?category=conferences&rlink=wrc&lang=en

WRC performs a complete and detailed review of the Radio Regulations RR (RR), and its Rules of Procedure (RoP)

WRC updates RR & RoP considering technological developments on Spectrum Radio and sector realities and challenges, to respond early and appropriately to these changes.

WRC have the authority to modify the RR by addenda, modifications or deletions they deem pertinent. These modifications are made by consensus, and only if necessary, would vote (one vote per administration).

WRC Duties

1. Consider any radiocommunication matter of worldwide character

2. Develop instructions to the Radio Regulations Board and the Radiocommunication Bureau, and review their activities

3. Determine issues considered by Radiocommunication Assembly and Study Groups as part of the preparatory work for WRC future

4 . Set agenda of next WRC, and subsequent draft.

WRC Calendar

WRCs performs every 3 (or 4) years; normally is held at Geneva, Switzerland, with a typical duration of 4 weeksLast WRC: Geneva, Switzerland February 2012 (WRC-12)Next WRC: - Geneva, Switzerland October 2015 (WRC-15)http://www.itu.int/en/ITU-R/conferences/wrc/2015 - Geneva, Switzerland 2018 (WRC-18)Inter WRC preparatory meetings (CPM) are held, typically two: 1st : the week after the WRC; 2nd : ~ 6 months before next WRC.

MS Spectrum DemandITU-R WP5D reported a range for IMT spectrum requirements of 1 340 MHz to 1 960 MHz for year 2020, for lower user density settings and higher user density settings, respectivelyQuestions on some parameters and assumptions used in the methods for calculating the spectrum requirements for MS resulting in an a never-ending exponential growth:

Super high data rates assumed: 30 Mbit/s to 100 Mbit/s/1 Gbit/sExcessive user density values assumed and not aligned with realistic demographic dataIncorrect assumptions about mobility in home and office environmentsUnclear relation between data traffic levels and spectrum requirements

MS and DTT Sharing StudiesFor the assessment of interference from the broadcasting service into the mobile service Recommendation ITU-R P.1546 will be used.For the assessment of co-channel interference from base stations into broadcasting, the prediction method in Recommendation ITU-R P.1546 will be used.For the uplink of the mobile service the modified Hata model as contained in ITU-R Report SM.2028 will be used together with all other parameters provided by WP5D.

Applications ancillary to broadcasting PMSECertain PMSE applications such as wireless microphones use the white spaces of the broadcasting service in the UHF bandPMSE applications are secondary services in many countries through footnote 5.296 for the land mobile service

Solution a: In the VHF range: 174-230 MHzSolution b: increased use in the UHF range: 470-694 MHz (white spaces)Solution c: Potential use of the centre part of the 700 MHz duplex gapSolution d: Potential use of the centre part of the 800 MHz duplex gapSolution e: Potential ranges between 1 200-1 650 MHzSolution f: Potential use of the centre part of the 1 800 MHz duplex gap
