The end of analogue TV and a completed switch to digital has freed frequency spectrum that can be used for other services now that TV services make more economical use of what was purely TV transmission bandwidth.  More programmes can be fitted in less space which has made room for ‘Fourth Generation’ (4G) mobile services related to fast, mobile broadband.

4G will involve much higher power base stations and mobile devices.  The mobile device could be a smart phone, tablet or a plug-in dongle.  The first roll-out is planned to cover Britain’s major conurbation areas so there is not likely to be rural benefit in early stages.

The base station signals required for the new services have the potential to with interfere with some existing TV reception.  TV aerials were traditionally manufactured just to cover a certain part of the TV spectrum related to local transmitters.  However to enable a smooth switchover most of the aerials installed in recent times cover the whole of the spectrum and therefore capable of receiving LTE, giving rise to potential interference.

Where a communal system is in place such as in blocks of flats or commercial buildings the problems could be more complex requiring trained, competent engineers and it is more than likely the owner of the system will have to cure the problem at their own expense.

We are able to diagnose and resolve issues with the new 4G service interference.
