The ZM3102N Z-Wave Module is a fully integrated RF communication module that uses the unlicensed Short-RangeDevice （SRD） frequency band of 868.0-868.6MHz in Europe， 902MHz-928MHz in US， 919.5MHz-920.0 MHz in Hong Kong， 921MHz-929 MHz in New Zealand， and 915MHz-928 MHz in Australia. The ZM3102N is dedicated for wireless control and monitoring of residential products like lighting and appliance control， energy management， access control， security and building automation. Together with the patented Z-Wave Protocol the ZM3102N Z-Wave Module delivers a complete highly reliable RF communication solution. The Z-Wave Protocol uses Frame Acknowledgement， Retransmission， Collision Avoidance， Frame Checksum Check and sophisticated Routing to assure reliable full home coverage.
