Ofcom has set the window for selling off more bandwidth to network operators.

80 MHz is up for grabs in the 700 MHz band, while 120 MHz will be available to bid on in the 3.6-3.8 GHz band.

The 700 MHz band provides "good-quality mobile coverage, both indoors and across very wide areas – including the countryside," while the 3.6-3.8 GHz band is “part of the primary band for 5G and are capable of carrying lots of data-hungry connections in concentrated areas."

The auction will be separated into two phases; the principal phase will see the companies bid for airwaves on traditional lots to determine how much of the spectrum each wins.

The second "assignment" phase bidding will see specific frequencies allocated.

Ofcom added that companies bidding in the 3.6-3.8 GHz spectrum can negotiate amongst themselves during the assignment phase.
