A system (10) and method delivers geolocation or other signals (26, 28) to a communication unit (24) located within an area (20) (e.g., a building) where an obstruction exists between the signal transmitter (12, 18) and the communication unit (24). The system (10) uses an infrastructure transceiver apparatus (14, 16, 22) to receive (204, 304, 604) the signals (26, 28) and retransmit (208, 310, 610) them within the area (20). A communication unit (24) calculates responsive data, such as its approximate position, from the retransmitted signals and reports (406, 704) the responsive data to a host system via the infrastructure transceiver apparatus (14, 16, 22).

[ What is claimed is:] [12.] A communication system comprising:multiple navigation satellites for sending geolocation signals;a repeater base station located in a proximity to an obstructed area within which the geolocation signals are significantly attenuated, wherein the repeater base station is coupled to an antenna which receives the geolocation signals from the multiple navigation satellites and to a signal distribution means dispersed throughout the obstructed area, the repeater base station retransmits the geolocation signals within the obstructed area using the signal distribution means, and the repeater base station reports an approximate position of a communication unit located within the obstructed area to a host system, wherein the approximate position is calculated from the geolocation signals; andthe communication unit located within the obstructed area, for receiving the geolocation signals which are retransmitted by the repeater base station.
