Looks like we will all have to retune our TVs again in the not to distant future. 
The United Kingdom’s telecoms regulator has today confirmed that the 700MHz (694-790MHz) radio spectrum band, which is currently used for Digital Terrestrial TV (DTTV) services, will be re-purposed for Mobile Broadband (4G / 5G) operators to use by Q2 2020; 18 months earlier than originally planned.Ofcom’s move, which will see existing television and wireless microphone services being gradually migrated into the neighbouring 600MHz band over a period of three years (starting in Q3/Q4 2017 – see the regulator’s roll-out MAP at the bottom of this article), has been in the works for the past couple of years.
In keeping with that the regulator has also confirmed that 20MHz of “centre gap” spectrum in the 700MHz band will be similarly allocated for use by mobile data, albeit specifically mobile downlink (SDL) type services. The rest can be used by the more traditional 4G based mobile services, such as those offered via Three UK, O2, Vodafone and EE (BT).
