Overview

Thewirelessnodes are based ondirect‐sequencespread spectrum(DSSS)communicationinthe 2.4‐2.5GHz
band,compliantwithIEEE802.15.4‐2006.

AllnodeshaveauniqueMACaddress,equivalenttoauniqueserialnumber.

Alldeviceshaveanon/offswitch.

Allnodesretaintheirconfigurationproperties
acrossapowerfailure.
