AsiaSat wants to make sure that harmonization of frequencies for electronic newsgathering adequately protects the fixed satellite and broadcasting-satellite services, it told ITU-R subgroups dealing with the issue. The potential tuning ranges under consideration for regional or worldwide harmonization…

include the 3,400-3,600 MHz, 4,400-5,000 MHz and 21.20-24.50 GHz bands, AsiaSat said. The 3,400-3,600 MHz band has been used for the fixed satellite service for 40 years, AsiaSat said. The 4,500-4,800 MHz band is the downlink band defined in regulatory and technical requirements for certain fixed satellite networks, AsiaSat said. The 2012 World Radiocommunication Conference will “decide on spectrum use of the 21.4 to 22 GHz band for the broadcasting-satellite service and the associated feeder link bands” in Europe, Africa, the former Soviet states and Asia. AsiaSat is also concerned about other frequencies that have the potential for ENG harmonization. The 5,850-6,725 MHz band is used as an uplink with the 3,400-4,200 MHz downlink band by almost all countries, AsiaSat said. The 6,725-7,025 MHz band is used for uplink with the 4,500-4,800 MHz downlink band, it said. Important government networks often use the 7,900-8,400 MHz uplink band and the corresponding 7,250-7,750 MHz downlink band, it said. The 7,025-7,075 MHz band is used for uplinks, sometimes to feed broadcasting satellite networks, AsiaSat said. It’s also worried about the 10.95- 13.25 GHz band, used by the fixed satellite service. An ITU- R working party coordinating studies for the possible worldwide/regional harmonization of spectrum for electronic newsgathering at the 2012 World Radiocommunication Conference “must show conclusively that existing or future deployment of [fixed satellite service] transmitting earth stations is not unduly limited,” AsiaSat said.
