In Summer 2013, mobile phone operators rolled out new fourth-generation (4G) networks to provide customers with high speed wireless broadband.
Where these services are broadcast on certain airwaves (the 800MHz band), they may interfere with Freeview reception*. A company, at800, was set up by the mobile operators to provide filters and other assistance to households where TV reception may be affected.
For more information, visit at800 or call them on 0333 31 31 800
(Freephone 0808 13 13 800).
*Existing 4G services from EE do not affect Freeview services as these operate in a different band.
The number of Freeview channels available at your address depends on the transmitter you receive your signal from. Check which channels are available to you at your address, using our predictive coverage checker.
The Freeview coverage checker gives a good indication of whether you’ll be able to receive Freeview. However, do bear in mind that it is a prediction based on an area 100 square metres around your address. There might be some addresses in that area which cannot receive Freeview, because of the exact location of the property and other elements of your local geography, such as tall buildings, trees or hills.
How does the Freeview coverage checker predict whether I am in coverage?
Broadcasters are always working to improve the TV transmission network and this sometimes means that engineering work needs to take place.
You can find out whether your TV service is being affected by work being carried out by the BBC on its network and transmitters through the BBC website.
The Digital UK website carries information on planned engineering works being carried out for all terrestrial TV services.
Is 4G affecting my Freeview signal?
Some boxes are programmed to let you know if they detect a channel or service that was not there before.
You must choose to either store this channel or to disregard it. To find out how to do this, consult the manual or try the manufacturer’s website.
How to retune – watch the video
Before the launch of any new channel there is usually information on the Freeview website detailing when it will take place.
If you wish to receive the new channel, we advise that on the launch day you should carry out a ‘retune’ or ‘rescan’ for channels on your digital box or digital TV to receive any new channels. You may find that your box does this automatically for you.
Retuning regularly is a good way to make sure that you are receiving all the great channels that Freeview offers.
Some boxes have a particular function which allows manufacturers to send software upgrades to their products. The downloads are usually sent to add new features to your box or to fix bugs in the software. You can check to see if a download was sent to your box by accessing the Digital TV Group (DTG) website.
Unfortunately DTG are only administrators of the airtime and cannot assist with technical enquiries from the public. If you do have any problems you will need to contact your manufacturer.
What’s a ‘software upgrade’ or ‘software update’?
Digital boxes are like PCs in that the software they contain is constantly evolving. Just as you can download software updates over the Internet to upgrade software on a PC and fix ‘bugs’, you can do the same with a digital box – except it is broadcast over the air alongside the digital TV signals in an ‘over-air-download’.
Most of the latest boxes will alert you of when there will be a broadcast update with a message on your TV screen and all you need to do is follow the instructions on your TV or it may even automatically update your digital box.
You can find the schedule of over-air downloads planned for specific manufacturers for this week on the Digital TV Group website.
