EE is aiming to cover 95% of UK landmass with 4G by 2020.

UK carrier EE has switched on the low-frequency 800MHz spectrum (Band 20) at 700 sites across the country, bringing 4G connectivity to 5,000 square kilometers of "not spots" overnight.

The carrier has relied on 1800MHz and 2600MHz thus far, and is now leveraging the 800MHz frequency for covering rural areas. High-frequency bands are ideal for urban centers as they have the ability to transmit more data, but the low-frequency 800MHz spectrum is less susceptible to interference and can cover a wider area, making it a better alternative in rural locations:

Today, EE has also switched on its low frequency 800MHz spectrum on 700 sites across the country, filling in 5,000 square kilometres of 4G not spots overnight and improving indoor signal in 500,000 homes. Parts of Shropshire, Somerset, Snowdonia, Oban, Glasgow, Berkshire and Derbyshire are among those getting 4G for the first time thanks to the switch on. Another 3,000 sites will be equipped with the low frequency spectrum before the end of 2017.

Customers will need a 4G Calling-capable phone to use the new low frequency signal. 4G Calling is available on monthly SIM and handset plans, on the majority of EE's device range. EE is committing today to launch its first 4G Calling smartphone under £100 in 2017 to provide an affordable choice for customers who simply want outstanding call quality and reliability, but may not need all of the features of the latest 4G smartphones.

With EE well on its way to blanket the UK in 4G, it is asking other carriers to get "Clear on Coverage".
