| S Jul 9, 2021 at 6:53 | comment | added | [continued] which also made that interference partially or almost totally dissapear (2 screens, one connected via hdmi-dvi cable, other displayport-dvi). Now I am waiting their call as we agreed that after office hours I will stop the pc and they have to check some graphs from the cell tower to see if interference is really gone when pc is stopped, t'ill second day. They did not offered me any cable, only asking politely to use a better quality cables :) (guess if not, they or whoever can fine me). | ||
| S Jul 9, 2021 at 6:53 | comment | added | yeah, I was also skeptical with them (2 people), they came to my home (not an aviator or smth :)) ) they showed me a badge wich looked legit. I googled his name and found that he is indeed working with commreg, also found an video interview with him, made from national tv channel which double confirmed. We tested by shutting down the pc, the interference dissapeared from their spectrum analyzer, then powering on again and disconnecting cables from video card [continued] | ||
| Jul 8, 2021 at 20:13 | comment | added | Andrew Morton | @google Oh, and do not use any phone number they supply you with: get it from the internet (before that person touches anything). A genuine employee will accept the delay, and might be grateful for a nice glass of fruit juice (you could lace it with truth serum! ... on second thoughts, don't do that.) | |
| Jul 8, 2021 at 20:04 | comment | added | Andrew Morton | @google Did you confirm the identity of the visitor with their supposed employer? Are you in any position that could be useful to a bad actor, e.g. you work in the aviation, power industries, some form of medium-to-high tech? Local "comm regulators" do not go round giving out free cables, unless someone knows otherwise. | |
| Jul 8, 2021 at 19:51 | comment | added | Andrew Morton | You could have switched off the equipment alleged to have been causing a problem while watching whatever indicator showed the interference, making sure that the operator was not touching the "portable spectrum analyser" at the same time. Discreetly, you should have also had someone else call the police: it is unlikely that OFCOM or whoever would have knocked on the door without without notifying you first. | |

| Jul 8, 2021 at 17:07 | comment | added | I also got a visit from local comm regulator asking to replace the hdmi cable at pc, which interferes with a gsm tower nearby (250 meters) also found this: independent.ie/business/technology/… | ||

| Mar 21, 2020 at 17:48 | comment | added | hobbs | @Damon the thing you're trying to imply (but not quite saying) is false. The power output of the cell tower isn't relevant here. The power received at the cell tower by an interference source, as compared to the power it receives from a handset, is. It's not about milliwatts vs kilowatts, it's about nearby milliwatts vs. a distant maybe 1 watt, in an inverse-square situation. | |
| Mar 21, 2020 at 15:02 | comment | added | Marcus Müller | @Damon you're overestimating cell phone tower power, I'd presume. Think about it – if all city cell towers would be consuming 3kW continously, and there's one for every ~500 people, what that would cost in energy! | |
| Mar 21, 2020 at 13:15 | comment | added | Damon | HDMI = 300mW total (of which most is consumed by the TV set for receiving the signal, and maybe, possibly, 5-10% are in the air when the leaky cable is an "antenna"). Whereas cell phone tower = 3-5kW. So... | |

| Mar 20, 2020 at 15:47 | comment | added | evildemonic | Googling your title brings up a few anecdotes of others having an HDMI cable knocking out wireless networks. I have a hard time believing there is a sufficient amount of power to interfere with the tower, but I don't know enough about it. | |
