[Wireless intercom...]

...with wires.

Wireless intercom, with wires.
I saw this intercom yesterday, but didn't get a chance to take a picture till today. It says wireless intercom, but there's a wire on the top and it runs all the way to the inside of one of the canteen stalls.

Wireless intercom, indeed.

The wire is a power line. Voice transmission could still be wireless. In the worst case scenario, you would save a data/voice line. In most cases, the distance from the device to the nearest power source constitutes a small of fraction of the total length between device and base.
