Abstract:
1. A method of managing transmissions in a wireless system having a wireless active radio frequency identification (RFID) tag device and a wireless access device, the method comprising: obtaining location-specific global positioning system (GPS) data at the wireless access device; generating, at the wireless access device, a locale message that conveys the GPS data; the wireless active RFID tag device receiving the locale message from the wireless access device, the locale message conveying the GPS data that indicates a location of the wireless access device; extracting, at the wireless active RFID tag device, the location-specific GPS data from the locale message; processing the GPS data with the wireless active RFID tag device; selecting, at the wireless active RFID tag device, one of a plurality of geographically-dependent wireless data communication schemes, wherein the selecting step is based on and determined by the GPS data and selects a wireless data communication scheme that is compliant with requirements of a geographic operating region of the wireless access device, and wherein the wireless data communication scheme specifies an operating frequency or frequency range and an operating power limit for the wireless active RFID tag device; and operating the wireless active RFID tag device in accordance with the selected wireless data communication scheme.
