The radio can be interfaced to PSoC3 via SPI. We do have our transceivers (CYRF7936) which work on 2.4Ghz ISM band and could be useful for short range connectivity with sleep currents below 1uA.
Over the longer range, one can use GSM or wi-fi connectivity to link PSoC3 to the internet for data upload. There is one custom component in PSoC design software Creator for interfacing with WLAN board from Redpine Signals.Alternatively for GSM, one can interface over UART from PSOC3 with off the shelf chip such as SIM300.
Yes conservative data exchange and ad-hoc sharing of computational load while processing/transmitting data over large area could be very beneficial in power critical applications.
Blog Make a Frequency Plan Tom Burke 17 comments When designing a printed circuit board, you should develop a frequency plan, something that can be easily overlooked. A frequency plan should be one of your first steps ...
