1. A system for providing location information to a wireless device, the system comprising:
- first, second and third wireless location transmitters, wherein each wireless location transmitter is positioned at a different fixed location, wherein each wireless location transmitter has a respective location in a coordinate-based location system, wherein each wireless location transmitter is programmed with data indicative of its respective location in the coordinate-based location system, and wherein each wireless location transmitter transmits its respective coordinate-based location to a wireless device; and
means for remotely changing the respective locations programmed in any of the wireless location transmitters and for remotely enabling and disabling any of the wireless location transmitters.

Abstract
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.

12. A system for propagating GPS signals inside a building, the system comprising:
-
a first wireless location transmitter for wirelessly transmitting a GPS location of the first location transmitter to a wireless device, wherein the GPS location of the first location transmitter is programmed into the first location transmitter, and wherein the first location transmitter is disposed within the building; a second wireless location transmitter for wirelessly transmitting a GPS location of the second location transmitter to the wireless device, wherein the GPS location of the second location transmitter is programmed into the second location transmitter, and wherein the second location transmitter is also disposed within the building; a third wireless location transmitter for wirelessly transmitting a GPS location of the third location transmitter to the wireless device, wherein the GPS location of the third location transmitter is programmed into the third location transmitter, and wherein the third location transmitter is also disposed within the building; and means for remotely changing the respective locations programmed in any of the wireless location transmitters and for remotely enabling and disabling any of the wireless location transmitters. - View Dependent Claims (13, 14, 15)

16. A method for determining a location of a wireless device in a coordinate-based location system, the method comprising:
-
wirelessly receiving from a first location transmitter a first packet that includes a location of the first location transmitter and a time that the first packet was transmitted by the first location transmitter, wherein the first location transmitter is located within an enclosure; wirelessly receiving from a second location transmitter a second packet that includes a location of the second location transmitter and a time that the second packet was transmitted by the second location transmitter; wirelessly receiving from a third location transmitter a third packet that includes a location of the third location transmitter and a time that the third packet was transmitted by the third location transmitter; and using the locations received from the first, second and third location transmitters to compute a location of the wireless device. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
