Is it illegal to interfere with mobile phone signals?

Mentally unbalanced downstairs neighbour has been pursuing a campaign of abuse for a year or so.  He successfully jammed my wifi signal so that I have to use use cables.  Now I find my mobile data is being constantly interrupted to the extent that some pages cannot be loaded at all.  And yes this all began before CV-19 increased demand.
Can anyone advise what my rights are?  If as I suspect it is the neighbour blocking the signal, can I pursue this with the council or communications agency or other?
Thanks for any advice.

    What evidence do you have that your neighbour is in some way blocking both your Wi-Fi and mobile signals?

    Nothing definitive as that would need specialist instruments.  The phone and laptop work fine in other wifi hotspots and when tethered at a local park using mobile data.  I'm 98% sure it's him blocking things.

    Again, why are you 98% sure it is your neighbour? You can't just throw wild claims like that.
    Try changing the channel on your router. Mobile data, it could be a number of things causing that. Do any of your friends or family on different networks get the same issue when in your house?

    Criminal offences

    Use of jammers

    It is a crime to use any apparatus, including jammers,   for the purposes of deliberately interfering with wireless telegraphy (radio communications) in the UK. The maximum penalty is two years’ imprisonment and/or an unlimited fine. See section 68 of the Wireless Telegraphy Act 2006

  • Thanks Andy_L that's pretty clear.  Don't suppose the Police will be too interested just now but perhaps in a few months time.

    I just use tethered data with the phone linked by wifi (or used to anyway).

    If you report this to the police they will probably also conclude that there's a mentally unbalanced person living in your building pursuing a campaign of abuse against one of their neighbours.

    Think it is harder to jam a wifi signal. The transmitter is local to you. For him to do it, it his signal will have to overcome the absorption of the wall and still be a significant strength to block yours, so he does need a very stong signal. There is a greater change of him conducting a deauthentication attack rather than blocking a signal, as it is much easier and cheaper.

    It may be something else, wireless weather station,? microwave oven,? also its offcom you report it to,  although I know of someone who did report it (the remote unlock on his and the neighbours  cars didn't work  within100 yards his house and  they came out (there was a charge £100 if memory serves) & it turned out it was his own super dooper wireless weather station!   ........they were very good about it.

    Oh.
    So there was me thinking that it was a bit odd that your Wifi and Mobile data were both playing up - but now you say that your wifi is just through mobile data. Seems you are just having issues with your mobile network, contact your provider.
  • Not overly sure it’s your neighbour, but blocking signals is illegal (I think)
