发明名称 System and method for wireless distribution of location-based information in an enclosure
摘要 A system for providing coordinate-based location information may include first, second and third wireless location transmitters. The wireless location transmitters may be located at fixed positions within an enclosure, such as a building. The wireless locations transmitters may each be programmed with a respective coordinate-based location, which the wireless location transmitters can in turn wirelessly transmit to a wireless device. The wireless device can then use the three respective coordinated-based locations of the wireless location transmitters to determine a coordinate-based location for the wireless device.
