Ofcom today announced some new rules for the upcoming 2.3GHz & 3.4Ghz mobile frequency band auction.

Rising demand for high speed mobile data has led to the release of these extra spectrums, which will amount to an almost one third increase in airwaves available to smartphones & tablets.

However, a couple of rules are going to be applied, to ensure competition is available in the marketplace.

The first rule is to limit the amount of 2.3Ghz spectrum that operators can win. This effectively means that BT/EE will not be able to bid for these.

The second rule is to cap the overall amount of mobile spectrum a single operator can hold as a result of the auction, amounting to 37% of all the spectrum expected to be usable in 2020, including the 700Mhz band.

Today, the UK’s four MNOs hold the following amounts of immediately useable spectrum:

  • BT/EE: 255 MHz
  • Vodafone: 176 MHz
  • Three (H3G): 90 MHz (plus 40 MHz – useable in 2020)
  • O2 (Telefonica): 86 MHz
