Sub 1Ghz RF Communication

Sub 1GHz radio communication is set up between 2 or more participants in a network, through e.g. standardized (ZigBee), open source (Simpliciti) or proprietary protocols. CC430 SoCs on both ends are offering all the flexibility needed through the integration of high performance RF transceiver and MSP430 ULP microcontroller on one chip.
