Ofcom aims to tackle 4G interference on digital TV services

Ofcom has outlined plans to prevent digital TV signals being interrupted by next-generation mobile services in the coming years.

From 2013, 4G coverage will be rolled out across the UK, with the technology set to make use of the 800MHz frequency band that will be auctioned off in 2012.

The proximity of the 800MHz spectrum to the frequencies currently used to deliver digital terrestrial TV (DTT) services has prompted Ofcom to publish the guidance.

According to the regulator, up to three per cent of DTT viewing equipment - namely TVs and set-top boxes - could be affected by interference if no steps are taken.

In some instances, consumers will be able to rectify the problem by fitting a filter to their aerial designed to block the unwanted frequency that interrupts normal reception.

However, in less than 0.1 per cent of cases, this will fail to solve the issue.

Ofcom is currently addressing the best course of action to take in this situation and is set to publish a further consultation on the matter in autumn.

The 4G auction will be the largest ever single sale of additional mobile spectrum to take place in the UK.
