Project mention: Ask HN: Does your microwave interfere with Bluetooth? Mine does | news.ycombinator.com | 2023-10-05

The 2.4GHz spectrum is shared between Bluetooth and WiFi 802.11b/g. A few years ago, I was doing some work using an Ubertooth-One scanner (https://greatscottgadgets.com/ubertoothone/). It was showing the traffic on different channels.
My wife stuck a burrito to warm up in the microwave a room away (30-40 ft). This was with a brand-name model, so presumably properly shielded, etc.
Nope. The entire spectrum just went white with noise on all channels.
Once the microwave cycle ended, it still took a good 15-30 seconds before the airwaves calmed down and went back to normal traffic.
