Functional Description

The HAN module receives power from the host device and has its own

microcontroller, RF circuitry, and permanently attached antenna. The HAN

module transmits and receives RF transmissions from an IHD and a programmable

thermostat.

The HAN module transmits and receives data using 16 channels spaced at 5 MHz

intervals across the 2.4 GHz ISM band. The first channel used is at 2405 MHz, and

the 16th channel is at 2480 MHz. The HAN module transmits to the IHD and

programmable thermostat for a maximum of 10 ms in a 100 ms interval for a 10%

duty cycle. The HAN module employs Offset Quadrature Phase Shift Keying

(OQPSK) without use of a subcarrier.

The HAN module serves as the network coordinator and communicates with other

ZigBee enabled Smart Energy devices such as thermostats and IHDs.
