Hardware update – new boards
We are testing three types of radio boards. All three are based on the TI cc2520 802.15.4 transceiver. The difference is the type of antenna used. The approximate range in the open (at 5 dBm power output) is more than 100 meters for the PCB and chip antenna versions and almost 200 meters for the whip antenna board.
Cost comparison : Whip antenna > Chip antenna > PCB antenna
Size comparison: Whip antenna > PCB antenna > Chip antenna
Range comparison: Whip > PCB antenna > Chip antenna
