All things pertaining to wireless and RF links

I am looking for a cost effective wireless anti theft solution for tablets placed on the tables. If the tablets are moved more than 15-20 meters from the table, an alarm should set of.

We will be deploying a tablet on each table in the restaurants and want to ensure none of the tablets get stolen by the staff or customers.

Suggestions? BLE? Something else.

PS: The tabs can be switched off since I can't prevent that so something needs to be stuck to the tablet which always keeps emitting some signals and a receiver which continuously receives the signals and sounds an alarm if signal is missed.
