Abstract
A radio frequency identification (RFID) tag is described that has both passive RFID tag features and active RFID tag features. In one example, the tag has a first radio transponder to transmit by backscattering a received signal, a second radio transponder to operate on a multiple access wireless network, and a connection from the first radio transponder and to the second radio transponder to transfer information about communications over the multiple access wireless network from the first radio transponder to the second radio transponder.

19. A method comprising:
-
communicating through a first radio transponder by backscattering a received signal; transferring information received through the first radio transponder about communications over a multiple access wireless network through a second radio transponder from the first radio transponder to the second radio transponder, the second radio transponder operating on a multiple access wireless network; and communicating over the multiple access wireless network through the second radio using the transferred information.
