(Telecompaper) UK communications regulator Ofcom has decided to use the 700 MHz frequency band for mobile broadband services following a consultation earlier this year. The regulator currently considers it likely that it will hold an auction up to 2 years before the spectrum begins to become available, which is expected at the start of 2022 or possibly as early as 2020. Using the 700 MHz band for mobile data will allow MNOs to meet meet increasing demand for mobile data with fewer base stations. The 700 MHz band is currently used for DTT and wireless microphones in the programme making and special events sector. Ofcom expects the great majority of homes to only have to retune their existing TV equipment, with a very small minority (around 0.5%) possibly needing to change their aerials in 2019 at the earliest.
