Call for Input: Making more spectrum in the 1.4 GHz band available for mobile services

The 1492-1517 MHz frequency block within the 1.4 GHz band has been identified for mobile use, and we are now considering how to make it available. The adjacent block of spectrum in the 1.5 GHz band is currently used to operate emergency communication satellite terminals on ships at and near ports, and aircraft at and above airports. Use of 1492-1517 MHz for mobile services is likely to cause interference to the receivers in these satellite terminals.

Ofcom is seeking views on the technical analysis we have conducted to estimate the likely extent of such interference, and on our initial views on the measures we could take to mitigate the interference risk. Additionally, we are also seeking stakeholders’ views on the format of a potential auction, as well as the most appropriate lot sizes.

The responses received in response to this call for input will help inform the development of any future proposals for how the 1492-1517 MHz spectrum should be made available.
