False advertising?

We went out for a Valentine’s Day lunch today. Very enjoyable Turkish BBQ food.

Near where we parked was this faded sign - with a wire running through it. I’m sure though that the “wireless” being advertised was for radios. So perhaps not false advertising after all.

This evening I was speaking with a couple of people about working from home and how all of this was made possible by the modern wireless - Wi-Fi.
