In the communications industry, more specitically the paging industry, messages are transmitted over the air via radio frequencies to a receiver or pager which is carried by a customer. The maximum distance between the transmitter and the receiver is determined by the amount of transmitter power and the number of trans- mitters. This distance is called the coverage area. A cus- tomer can remain completely mobile within the coverage area and still receive messages from the transmitter(s). However, there will be certain areas within the coverage area that radio frequencies can be blocked or altered (basements, tunnels, etc.) thus a message may not be received. These areas are generally well known by the service provider (Radio Common Carrier) and custom- ers are generally made aware that coverage in these areas is not guaranteed. A customer may also leave the speci- tied coverage area and will not receive any messages.
