Abstract

See full text

In certain embodiments, an RFID tag comprises a memory module and one or more processing units. The memory module stores a subscriber identification number shared by the tag and one or more other tags for accessing a WWAN. Each tag is operable to access the WWAN using the subscriber identification number at a corresponding unique timeslot, the corresponding unique timeslot for a tag being distinct from the timeslots at which the other tags can access the WWAN using the subscriber identification number. The one or more processing units access the WWAN using the subscriber identification number to initiate a tag session at the corresponding unique timeslot for the tag. The corresponding unique timeslot for the tag is distinct from timeslots at which the other tags may access the WWAN using the subscriber identification number. The one or more processing units are operable to communicate tag information during the tag session at the corresponding unique timeslot for the tag.
