Expecting 4G interference? Tests now show that you have a one in 300 chance

Remember the scare stories in the papers? Millions of homes will have problems when 4G starts... Even the Ofcom figures suggested 760,000 homes would have problems. The 4G tests suggest the just 90,000 homes will need to fit a filter.

published on UK Free TV

Looking back the the original posting, Ofcom moves to protect Freeview interference from 4G mobile, we can see the Ofcom suggested that:

Of the 16.3 million UK homes with a standard (unamplified, unshared) Freeview reception, 110,000 (0.67%) would be effected.

Of the 5.2 million homes using communal aerials systems, 550,000 (10.6%) will have problems.

Of the 5.6 million homes using amplified Freeview reception, 100,000 (1.8%) will experience problems.

Today, at800 have published the results of the tests in London, Brighton and Hove and York - at800 updates estimate of likely impact of 4G at 800 MHz on Freeview:

"Following tests conducted across the country, at800, the organisation responsible for protecting Freeview when 4G at 800 MHz is rolled out across the UK, has provided a new estimate of the likely scale of the impact. If national rollout reflects the results seen during its tests, at800 expects no more than 90,000 households, with Freeview as their primary TV service, to experience disruption caused by 4G at 800 MHz. Whatever the level of disruption, at800 is ready to restore Freeview to viewers.

at800 has now sent postcards to households in London and the surrounding areas in preparation for the activation of 4G at 800 MHz masts over the coming weeks and months. at800 is also sending postcards to other areas of the UK ahead of masts switching on. at800’s mailing does not mean that 4G services will be available to consumers. For information about the availability of 4G services, people should contact their mobile operators.

In London, in particular, Freeview received from the Crystal Palace transmitter is unlikely to be affected by mast activation because of the strong terrestrial television signal and its relatively large frequency separation from 4G at 800 MHz. However, at800 is sending postcards and running a publicity campaign to ensure anyone who does experience new disruption to their Freeview service knows how to get in touch."

So with 26.50 million TV households in the UK (see Monthly universe summary - BARB) 90,000 represents 0.340% of them - that's a ONE IN THREE HUNDRED chance.

It seems that you are most likely to need a filter if:

a) you are a long way from a high power Freeview transmitter; and

b) you are very close to a 4G mobile phone mast; and

c) you are using a booster.

That's good news for Freeview viewers.

If you have had a postcode from at800 - see Received a postcard from at800?

I am on the fringe of Brougher freeview transmitter.
RTE reception is OK but BBC and ITV very shakey or absent this evening.

Has anyone else in the KT13 area, receiving Freeview from Crystal Palace, reported pixellation and intermittent loss of signal on the COM4 mux (C25) during the past week?
For me the affected channels are QUEST, Drama, BTSport, 5* and 5USA.

Is there testing on a 4G Mast in the KT13 area?

Pete- Do you have a booster of some sort fitted? I've known failing boosters to let BBC channels thro (strongest) and lose PickTV (weakest), Also have you done a signal test using "Manual Tune" on your TV ?

Dave Martin- Do you have a working Aerial Point in your house? Has the Bush been working before? Why did it stop? Where are you (postcode)?

Pembroke Dock

I live in Pembroke Dock SA72 6HL and have started experiencing minor free view interference intermittently. Is this likely to be linked to 4G @ 800mhz? I have not received a postcard from at800.

Jim Stobbart- As far as I'm aware, 4G does not yet operate and thus, cannot cause interference
