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?

Jack Luxon: I'm not sure that Ofcom Sitefinder will mention 4G base stations.

The main page states:

"The last Sitefinder update was done in May 2012, although some operators ceased providing updates from as early as 2005. This is largely a result of the Information Commissioner's decision in 2007 ordering Ofcom to make the raw data used to populate the Sitefinder database publically available, causing some operators to stop voluntarily providing the information. It should also be noted that participating operators have provided their respective datasets at different intervals and some of which may be more recent than others."

Dave Lindsay: which means that the data shown here on UK free TV is the same as you will find on site finder...

I am suffering severe disruption to the Freeview service and suspect 4G interference. Should I try a filter and if so where would I obtain one?

R Pearce: Given that there are "0 mobile phone masts within 1.5km of your location", this suggest your chances of 4G interference are miniscule.

I would have a look at Freeview reception has changed? | Freeview Interference | - 11 years of independent, free digital TV advice instead.

since 4g came on a few months ago in
my area North Glasgow, I have had nothing but trouble. Numerous calls resulted in engineers coming out and fitting filter. No success so filters were removed. Aerial not at fault, new and checked. What happens now? Do we just have to live with this?

G. Murphy: If you supply a postcode, you can see for yourself if there are any 4G transmitters near you. If there are not, then fitting a filter would make no difference to the problem, and if there are ones nearby, then its possible that its nothing to do with 4G anyway (which is highly likely).

Also explain what the nature the problem is - is the signal breaking up, and what is the signal strength - high or low?

my postcode of; PA28 6PW covers addresses that are over a mile apart, and differ in elevation by over 100 feet.
before digital, i used to receive "channel 5",from darvel, when no one in campbeltown could get it.
once digital came in i used darvel to get many stations, including "yesterday", but then "history", on channel 19. also sky news on 82, and RT on 83. once campbeltown went digital, i lost those channels most of the time, but on occasions could get sky news on 82. in the last week, signal levels have been erratic. sometimes so low as to get neither sound nor picture. sometimes frozen picture with sound, and at times no picture but sound! it is not weather effect, because one dry windless day there was zero signal on any channel for over an hour before it came back. one day there was a low signal, but adequate reception, two days later there was a stronger signal, but less good reception!
i feed three sets, one of which indicates "black hill" as the transmitter, but darvel is a slave to black hill.
any thoughts?

MikeB: BBC drops off at 9:45pm, leaving screen with "No video signal." ITV and several other commercial channels are not interrupted. I have been away over Christmas/New Year, but suspect this loss of signal could date from December (BBC recordings are incomplete). I have Freeview. I live in North Birmingham. Any thoughts?
