Będzie więcej niskich częstotliwości dla mobilnego internetu

Alokację większych zasobów częstotliwości radiowych w paśmie 694-790 MHz dla mobilnych systemów dostępowych zaleciła zakończona w ubiegłym tygodniu konferencja radiokomunikacyjna ITU (World Radio Conference 2012).

Głosami reprezentantów krajów afrykańskich i arabskich przegłosowane zostało zalecenie, przeciw któremu protestują nadawcy telewizyjni w krajach europejskich, którzy obawiają się uszczuplenia zasobów radiowych przeznaczonych do nadawania naziemnej telewizji cyfrowej po ostatecznym wygaszeniu nadawania analogowego w Europie. Plenum WRC ich argumenty jednak nie przekonały.

Alokację pasma 694-790 MHz dla systemów komunikacyjnych z rodziny IMT wpisano w agendę kolejnej konferencji WRC w 2015 r. I nie wcześniej zostaną podjęte kroki do formalnego otwarcia nowego zakresu dla operatorów telekomunikacyjnych.

GSM Association

, organizacja operatorów komórkowych, podkreśla, że o ile dzisiaj w technologiach z rodziny IMT działa 1,7 mld terminali mobilnych, o tyle w 2015 r. będzie ich ponad 3,6 mld, co oznacza znaczny wzrost popytu na pasmo radiowe. Branża telekomunikacyjna podkreśla efektywność pasma na niskich częstotliwościach: koszt budowy sieci 3G/4G w zakresie 700 MHz ma być trzykrotnie niższy w porównaniu z wykorzystaniem popularnego dla 3G zakresu 2,1 GHz.

RESOLUTION COM5/10 (WRC-12)

Use of the frequency band 694-790 MHz by the mobile, except aeronautical mobile, service in Region 1 and related studies

The World Radiocommunication Conference (Geneva, 2012),

considering

:

a) that IMT systems are intended to provide telecommunication services on a worldwide scale, regardless of location, network or terminal used;

b) that some administrations are planning to use the band 694-862 MHz, or part of that band, for IMT;

c) that the frequency band 470-806/862 MHz is allocated to the broadcasting service on a primary basis in all three Regions and used predominantly by this service, and that the GE06 Agreement applies in all Region 1 countries, except Mongolia, and in the Islamic Republic of Iran in Region 3;

d) that the band 645-862 MHz is allocated on a primary basis to the aeronautical radionavigation service in the countries listed in No. 5.312;

e) that cellular mobile systems in the three Regions in the bands below 1 GHz operate using various channelling arrangements;

f) that where cost considerations warrant the installation of fewer base stations, such as in rural and/or sparsely populated areas, bands below 1 GHz are generally suitable for implementing mobile systems including IMT;

g) that bands below 1 GHz are important, especially for some developing countries and countries with large areas where economic solutions for low population density areas are necessary,

noting

a) that, as a result of the transition from analogue to digital terrestrial television broadcasting, some countries are planning to make, or are making, the band 694-862 MHz, or parts of that band, available for applications in the mobile service;

b) that the transition from analogue to digital television shall end on 17 June 2015 at 0001 hours UTC according to Article 12.6 of the GE06 Agreement;

c) that the transition from analogue to digital television is expected to result in situations where parts or all of the band 470-806/862 MHz will be used extensively for both analogue and digital terrestrial transmissions, and that the demand for spectrum during the transition period may be even greater than the stand-alone usage of analogue broadcasting systems;

d) that Recommendation ITU-R M.819 describes the objectives to be met by IMT in order to meet the needs of developing countries, and in order to assist them to "bridge the gap" between their communication capabilities and those of developed countries;

e) that Recommendation ITU-R M.1645 also describes the coverage objectives of IMT;

f) that WRC-12 has approved Resolution COM6/8 (WRC-12) which includes studies to be carried out by ITU-R in time for WRC-15,

recognizing

a) that there is a need, in many developing countries and countries with large areas of low population density, for the cost-effective implementation of IMT, and that the propagation characteristics of frequency bands below 1 GHz identified in Nos. 5.286AA and 5.317A result in larger cells;

b) that some countries also plan to use the band 470-862 MHz for HDTV and other higher definition modes;

c) that in Region 1, in accordance with No. 5.296, a number of countries have deployments of applications ancillary to broadcasting operating on a secondary basis, which provide tools for the daily content production for the broadcast service;

d) that the GE06 Agreement contains provisions for the terrestrial broadcasting service and other primary terrestrial services, a Plan for digital television, and a list of stations of other primary terrestrial services;

e) that the time-frame and transition period for the analogue to digital television switchover may not be the same for all countries;

f) that there is a need for countries to assess the consequences of a new allocation for the mobile service below 790 MHz on the equitable access to spectrum in the GE06 Plan,
