Just 15 homes from an area of 22,000 properties were affected by 4G signals in the first TV interference tests carried out in the West Midlands.
The company responsible for the tests, at800, started the tests in March and revealed that it had predicted 120 households would be hit by the issue, but as it turns out the number was far lower.
Of the more than 100 calls logged by at800, only 15 instances of problems with TV reception could be attributed to 4G at 800MHz. The rest of the calls were general queries for more information, or about issues unrelated to 4G interference, the firm told V3. For the 15 households affected, the organisation then fitted the necessary filters to block out the interference and this appears to have solved the issue.
The results should help the organisation better understand the likely impact of the issue around the rest of the UK.
“This was a useful, small-scale test. We’ll now improve our forecast model and look at the approach we use to tackle the issues we’ve seen,” said at800 chief executive Simon Beresford-Wylie
“Further extensive evaluation will occur during April and May as masts are switched on for tests across larger urban areas.”
The next set of tests will take place in a larger urban area in the coming months, although no specifics of the area have yet been announced.
The at800 group has been formed to ensure that as many as two million potential homes do not lose digital TV signal in the 700MHz band as 800MHz 4G services come online later this year from the likes of O2 and Vodafone.
Any homes affected will be given filters that cost anywhere between £20 and £150 per time. This has meant operators have put aside funding to the tune of £180m to tackle the issue.
