WiFi has always used the microwave frequency range, and badly designed microwave ovens (that don’t fully isolate the waves inside) have always been a problem for WiFi. The use of 2.4 GHz in ovens is one of the primary reasons it’s an unlicensed frequency range. The interference is one of the reasons 5 GHz was added as another frequency to use for WiFi.
- anotherhue 6y agoCommercial ovens, medical diathermy, and a few shenanigans from GE are why 2.4 is open. [1] I don't believe it is correct to say 5G was added due to interference, the development time ines suggest it was more for throughput. 1: https://www.indiegogo.com/projects/why-2-4ghz-chasing-wireless-history https://www.indiegogo.com/projects/why-2-4ghz-chasing-wirele...
- kevin_thibedeau 6y ago5GHz wireless phones were deployed to deal with a crowded 2.4GHz band flooded by baby monitors and other BW hogs. This was all before wifi became ubiquitous. Funny enough the rare digital spread spectrum 900MHz phones that came out just before the higher frequencies took over were great because of limited use by that time plus minimal interference from walls and analog phones.
