The door of a microwave typically doesn't form an RF-tight seal. Instead there's a groove that forms a resonant trap at the microwave's operating frequency. So it'll probably block 2.4-GHz ISM-band stuff like Bluetooth (I don't actually know how wide the trap band is compared to a BT or wifi channel), but outside that band all bets are off. |
