Radio frequency communication devices having backscatter and non-backscatter communication modes and hardware re-use
Abstract:
Backscatter communication offers the potential for significant energy savings compared to conventional wireless links such as Bluetooth, Zigbee, WiFi, etc. However, backscatter communication requires the presence of a carrier source in the environment at an appropriate frequency. If such a carrier source is not available in the environment, backscatter communication may not be practical. Examples are presented for a radio frequency communication device having the option to use either backscatter communication, or non-backscatter communication, with the re-use of at least portions of the hardware components between the backscatter and non-backscatter communication modes.
