Say we have a remote transmitter that is not connected to a wifi router (neither wirelessly nor by cable), but which transmits information using electromagnetic waves. Examples include walkie-talkies, mobile phones, and other devices like Bluetooth.
In this case, can the wifi access point (after being “hacked” or something) be used to receive and retrieve other signals?
Since a wifi router can be hacked, would other signals transmitted near the wifi router face the danger of being compromised and eavesdropped as well?
