The reason microwave ovens disrupt WiFi is that they both use the same unlicensed 2.4GHz spectrum. The reason that spectrum is unlicensed is that it is absorbed by water, so does not travel far.
- Microwave ovens can only leak electro-magnetic radiation if the shielding isn't enough. When does this happens? With old microwave ovens over the age of ~8 years.
- Theoretically the leaking of this radiation would probably only disrupt 802.11b. 802.11g uses OFDM (Orthogonal frequency-division multiplexing) which is rather strong so my guess would be a microwave operating at a center frequency of 2450 MHz with a sideband of 0Hz wouldn't cause a lot of damage to 802.11g.
Did the testing one month ago for 802.11b and 802.11g and I wasn't able to produce any disruptions. But the microwave ovens I tested where 6 years or newer. Apparently a colleague of mine did eventually succeed in disrupting 802.11b by using a really really old microwave used by a granny living next door.
Bluetooth, metals, water and human interference cause the worst problems. Bluetooth just shatters anything in the 2.4GHz frequency. It's selfish, doesn't cares what other devices do and wants to use a pseudo-random part of the spectrum for short bursts of time (shifts frequency 1600 times a second). Hence it causes major collisions in the RF spectrum. Luckily the little fucker is limited in power and range.glasnt wrote:I didn't realise magical nuking machines interrupted wireless. I only thought it was bluetooth-remote controlled surround sound systems. We had that issue once, but it's ok, because the PCs were LAN connected, and the Macs were having the issue.
The GeoCities joke is awesome by the way.
