Freeview and 4G at 800 MHz coexistence test in south east London

Filed In: PilotPress Releases

A test to help understand the extent to which 4G at 800 MHz may disrupt Freeview is being run in south east London. at800 is asking viewers in the area to report problems with television reception from Monday 15 April. at800 is the organisation tasked with ensuring viewers continue to receive Freeview when 4G mobile services at 800 MHz are launched later this year*.

Approximately 170,000 household and business addresses in parts of Greenwich, Lewisham, Southwark and Tower Hamlets are being contacted directly to alert them to the test. This larger-scale testing follows an initial small-scale test in the West Midlands**.

at800 has a team of professional aerial installers and testing units in the area that will respond to calls from viewers, visit addresses reporting problems and restore Freeview.

Only new 4G services that will roll out at 800 MHz have the potential to cause problems to Freeview reception. 4G enables mobile devices such as smartphones, laptops and tablet PCs to access the internet at super-fast speeds and is expected to bring innovations in business, entertainment, education and public services.

Simon Beresford-Wylie, chief executive of at800, said “These larger tests are essential to help improve our forecast model and the way we’ll tackle potential issues caused by 4G at 800 MHz. We are extremely grateful to viewers in south east London for their help with these important tests.”

If you live in the south east London area and notice problems with your Freeview service from 15 April, please contact at800 by calling 0333 31 31 800. You will be asked for your postcode, the type of interference and the time it occurred. This will allow at800 to restore your service as soon as possible. Freeview is the television that viewers receive through their aerial.

at800 has advised that if you’ve not been contacted directly through the post any interference to your Freeview service is unlikely to be due to the 4G test.  TVs connected to a cable or satellite service are not affected.

Notes

About at800

 at800 is the consumer brand of Digital Mobile Spectrum Limited (DMSL), the organisation responsible for ensuring people continue to receive free-to-air television when 4G mobile services operating at 800 MHz are launched. The organisation is funded by the UK mobile operators with 800 MHz spectrum allocations to provide 4G services – EE, Telefónica UK (O2), Three and Vodafone.

Background

 *4G mobile services at 800 MHz and digital TV operate in adjacent parts of the radio spectrum.  Equipment that receives television signals, such as aerials, amplifiers, and digital tuners, can fail to block 4G at 800 MHz. This can cause loss of sound, blocky images or loss of some or all Freeview channels.  Freeview is the television viewers receive through their aerial.  BT Vision, YouView, TalkTalk and Top Up TV also provide Freeview services. Satellite and cable TV services are unlikely to be affected by 4G at 800 MHz.

at800 will contact those households it predicts may be affected by this issue before 4G at 800 MHz is switched on in their area.  It will also contact businesses, social housing departments, care homes, hospitals, schools and colleges to advise what action needs to be taken.  Special arrangements are being made to support vulnerable people.

Domestic at800 filters are smaller than a pack of cards and when installed correctly block 4G frequencies at 800 MHz, enabling viewers to receive and watch Freeview as normal.

**The first tests were conducted in the Cradley Heath and Rowley Regis areas of the West Midlands between 18 and 30 March 2013 https://at800.tv/press-releases/pilot-in-cradley-heath-and-rowley-regis/
