Proxy Solutions works with a receiver and tags. If the tag comes near the receiver, one or more actions will happen.

You can choose to place the receiver on the vehicle or somewhere in the warehouse.

With he first possibility the tags are placed somewhere in the warehouse, like for example at a busy cross road. When the receiver/the vehicle comes close to the cross road/the tag, an action is caused by the receiver. For example a honk, this lets other vehicles /employers know a vehicle is approaching.

With the second possibility the receiver is mounted somewhere in the warehouse and the tags are placed on the vehicles/employees. Now they know when a vehicle is approaching via a lamp or sound signal.
