Are civil aviation aircraft transmitting blocking signals?
Discussion
Hello everyone,
This particular question has come up in my mind again as I use mainly WiFi at home.
Of course, my wireless broadband drops out now and again but as I live under the Heathrow flight path in Chiswick, I have found that I can pretty much guarantee that once I start to hear the engines and they come within a certain distance,that my connection goes.
Always comes back almost instantly once the aircraft has passed and because things like this (broadband dropping out) annoys me, I have vaguely looked up which aircraft/airline it may be.
Seems to be the same half a dozen airlines and not all major carriers. Of course, I am not going to publish a list, just in case.
has anyone had this experience? i know the reasons why? It should be this way but is it the same for lots of people or is my brain just working overtime?

I'm sure any signal blockers are illegal, but they may interfere with certain frequencies.
You could try swapping onto a different wifi channel and see if that helps
I have done the channel swap thing to optimise reception at home..... brick walls and kitchen (electrical equipment etc) near to where the modem is sitting. It was particularly more severe this 'summer' and I had most of the signal going towards the garden, so I could watch the Grand Prix after work on a Sunday evening....I always seem to end up working on a GP Sunday-that is when I notice the drop out most severely. Oh and first thing in the morning, just as the intercontinental flights are starting to arrive.You could try swapping onto a different wifi channel and see if that helps
WiFi equipment is by nature very broadband for each receiver and therefore susceptible to interference from microwave signals in the next frequency band (or further). It would not take a very strong signal to block or corrupt the WiFi received data.
So maybe the airlines concerned are using microwave radio altimeters in their aircraft.....
