Freeview interference from 4G-at-800 London tests start Monday 15th April 2013

At800, who are tasked with preventing interference to Freeview from the new 4G mobile internet signals, will move this week to the second stage testing.
About 170,000 household and businesses in Southwark, Lewisham, Greenwich and Tower Hamlets have already been mailed to tell them to call the at800 hotline - 0333 3131 800 if they experience problems.
The approximate test area is:
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 will restore Freeview viewing.
Callers to the helpline will be asked for your postcode, the type of interference and the time the interference occurred. This will allow at800 to restore your service as soon as possible.
