RegionFrequency
Europe868.42MHz
United States908.42MHz
Australia/New Zealand921.42MHz

Network Topology

Z-Wave uses a source-routed mesh network topology. The mesh network allows devices to send messages through other Z-Wave devices before reaching the destination, allowing the message to “hop” between devices to extend the communication range and overcome RF dead spots.
