The launch of 4G mobile broadband services in the 800MHz radio spectrum band could affect more TV viewers than originally thought.
Last year, Ofcom revealed that next-generation services are likely to cause interference for around three per cent of UK homes - approximately 760,000 households.
In order to provide solutions - such as special filters, new aerials and different TV platforms - the government set aside a £180 million fund.
However, Communications Minister Ed Vaizey has confirmed that the launch of 4G could create viewing problems for as many as two million households.
As reported by the Daily Mail, he said 945,000 homes which use signal amplifiers to boost their TV reception could be affected.
Mr Vaizey added that another 953,000, which are currently reliant on communal aerials, could also experience signal problems.
