at800.tv Predict Just 90k UK Homes to Lose TV Due to 4G Interference

Following a number of trials at800.tv (DMSL), which is funded by £180m from mobile network operators, has predicted that just 90,000 homes in the United Kingdom will see their Digital Terrestrial TV (DTTV) services being disrupted by the new generation of 4G based Mobile Broadband services in the 800MHz band.

The prediction, which is well below Ofcom’s original estimate of 900,000 households (i.e. those where terrestrial TV services are used as the “primary viewing” method), follows several recent reports in which at800.tv noted that its trials had shown significantly fewer reception problems than first predicted (here).

In other words less than 1% of UK households are likely to need a special filter to remove the interference from 4G, which will no doubt come as good news to country’s various mobile operators and TV broadcasters. On the other hand the filter manufactures may be feeling somewhat less pleased.

at800.tv Statement

at800 has now sent postcards to households in London and the surrounding areas in preparation for the activation of 4G at 800 MHz masts over the coming weeks and months. at800 is also sending postcards to other areas of the UK ahead of masts switching on. at800’s mailing does not mean that 4G services will be available to consumers. For information about the availability of 4G services, people should contact their mobile operators.

In London, in particular, Freeview received from the Crystal Palace transmitter is unlikely to be affected by mast activation because of the strong terrestrial television signal and its relatively large frequency separation from 4G at 800 MHz. However, at800 is sending postcards and running a publicity campaign to ensure anyone who does experience new disruption to their Freeview service knows how to get in touch.

The first 800MHz based 4G services are due to come online this summer and others will follow later in the year. at800.tv, which will supply special filters and services to those affected by the launch, said, “Whatever the level of disruption, at800 is ready to restore Freeview to viewers“.
