Operators to test 4G impact on Freeview in west London areas


UK operator JV at800 has expanded its test of whether 4G mobile services interfere with Freeview TV when run on the same spectrum band to Brentford and Isleworth

Operator joint venture at800 is to test whether 4G mobile services will interfere with Freeview TV signals in West London boroughs Brentford and Isleworth.

at800 was set up by EE, Vodafone, Three and O2 to make sure 4G services using 800MHz frequencies do not interfere with Freeview TV, which also uses the band, when the superfast mobile internet service is launched later this year.

The test begins on April 29, before which households will be sent filters which they can use to block 4G at 800MHz in the event of interference.

at800 chief executive Simon Beresford-Wylie said: “This test will help us assess any problems viewers may have with fitting filters and whether receiving one in advance improves awareness and understanding of the potential issue. We will have professional testing units and aerial installers in the area to help get Freeview services back to normal if they are affected by our test.”

Tests carried out earlier this year in the West Midlands show 4G services had a lower than expected effect on Freeview customers, with only 15 households out of 22,000 surveyed reporting interference.

The JV is also currently testing 4G interference on Freeview in approximately 170,000 households and businesses in parts of Greenwich, Lewisham, Southwark and Tower Hamlets.
