Hi Luis, 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. Regards Umanath

Hi Dale, 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. Regards Umanath

Thanks for the article. What frequency range does the PSoC3 work on? 2.4GHz ISM band? Does it include the radio? Which kind of radio? Bluetooth? Zigbee? Thanks for the very interesting topic.

Conservative data exchange also 'plays' a very significant role in power conservation.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
