Abstract
An apparatus, a system, and a method for communication between multiple base stations and radio frequency (RF) transponders (RF Tags) is disclosed. A first radio frequency (RF) base station for communicating RF signals with an RF tag communicates external trigger signals with at least a second RF base station, which causes the second RF base station to begin transmission.
