British telecoms regulator Ofcom has launched consultation into a request by UK Broadband, which is owned by mobile network operator Three UK, to vary its existing spectrum licence. The company currently holds a concession which authorises it to use 168MHz of radio spectrum across two separate 84MHz blocks – 3605MHz-3689MHz (the ‘lower frequency block’) and 3925MHz-4009MHz (‘upper frequency block’). UK Broadband has reportedly requested a ‘number of changes’ to this licence concerning the lower frequency block, including: shifting it down by 5MHz, surrendering its rights to use 4MHz of spectrum in that block, and changing the applicable technical conditions. Ofcom has said it provisional view is that it is minded to agree with the operator’s variation request, but it has invited comments from interested parties on the matter before making a final decision. Submissions to the consultation will be accepted until 8 August 2018.
