Tests designed to investigate the possibility of 4G interfering with the Freeview signal are due to take place over the next fortnight near Dudley, West Midlands.
Fears have been raised that the 800MHz band could disrupt Freeview transmissions to around 2 million homes in the UK. The tests, which start today and conducted by Digital Mobile Spectrum Limited, the organisation tasked with cutting down radio interference, are intended to measure the impact, if there is any.
Digital Mobile Spectrum Limited – also known as AT800 – has been given £180m by network operations to ensure 4G networks don't knock out Freeview transmissions, which neighbour them in the radio spectrum.
Areas where interference is likely – or where it is proven to occur – will be provided with filters designed to cut down on the interference.
As part of the tests, residents to the west of Birmingham and those in the Dudley area are being asked to report if they experience interference to their Freeview signals over the next couple of weeks.
