Claim:
1. A radio frequency identification (RFID) tag, label or inlay comprising: a chip; at least a first antenna and a second antenna coupled to the chip for receiving incoming signals and sending outgoing signals; a physical or virtual antenna control switch coupled to the chip configured to select either the first antenna or the second antenna, wherein the chip includes control logic that is part of a processor of the chip that is operatively coupled to an adjustable modulator configured to change circularity of the outgoing signals such that the outgoing signals are left or right hand circularly polarized; the control logic including logic configured to adjust the adjustable modulator to set a data rate of the outgoing signals, such that the outgoing signals are at least in part based on a data rate of the incoming signals and when the incoming signals consist of a high data rate and are detected, the outgoing signals are sent at a higher data rate and wherein the control logic is configured to perform the operations of 1) determining whether to send the outgoing signals, 2) controlling characteristics of the outgoing signals, 3) using a decision tree, decision table, decision matrix, flow chart, or algorithm for determining control of the outgoing signals, 4) controlling the physical or virtual antenna control switch to select either the first antenna or the second antenna for sending the outgoing signals, and wherein each of the operations is based at least in part on, 1) a non-informational characteristic of the incoming signals received by the RFID tag, label or inlay, and 2) environment information received by an environment sensor of the RFID tag, label or inlay, and wherein one of the non-informational characteristic of the incoming signals or the environmental information received by the environment sensor selectively couples either the first antenna or second antenna to the chip.
