Abstract
A mobile wireless system includes a transmitter such as a satellite that broadcasts wireless signals such as boundaries for specific areas to a mobile receiving device. Mobile receiving device may include an antenna and a mobile receiving device. A locating receiver is used to generate locating signals so that a determination may be made to the location of the mobile receiving device. When the mobile receiving device approaches the boundary of the designated marketing area, a warning is generated.
