摘要： A portable receiving/transmitting unit is adapted to communicate with a master station, the master station being associated with a plurality of base stations, a plurality of pagers and a plurality of individual receiving/transmitting units. The portable receiving/transmitting unit includes, integrated into one unit, structure for receiving a data string encoding a personal message which is broadcasted by the master station together with a unit identifying code through a plurality of pagers; structure for conveying the broadcasted message to the operator of the receiving unit identified by the identifying code; and structure for generating a message and for transmitting it from the portable unit to the receiving base stations together with a unit identifying code.

摘要： Systems, devices, methods, and computer-readable mediums for generating a radio map of an area are disclosed. In one aspect, the device, method, and computer-readable medium perform processes that may include receiving in at least one processor first information associated with at least one wireless device at a first location in the area. The processes may include receiving in the at least one processor second information associated with at least one wireless device at a second location in the area and different from the first location. The first location within said area and the second location within the area are unknown to the at least one processor. The processes may also include generating a radio map of the area using the first information and the second information.

摘要： A wireless local area network (WLAN) radio-frequency identification (RFID) tag system provides location finding in a wireless local area network (WLAN), using a WLAN channel. Interference with the WLAN is prevented by either using a sniffer circuit to determine that no network transmission is in progress, using a modified coding sequence or preamble to cause standard WLAN receivers to ignore the RFID tag transmissions, or transmitting a message using a standard WLAN signal addressed to an address not corresponding to a unit within the WLAN. Location units (LUs) and a master unit (MU) within the WLAN receive the RFID tag transmissions and can determine the location of a tag by triangulation based on differences between the signals received at the location units from the tag. The master unit receives the signal information from the location units and computes the location of the tag. Time-difference-of-Arrival (TDOA), received signal strength indication (RSSI) or other triangulation techniques may be used.
