ZigBee nodes can only send data requests to other nodes on the same network. A single ZigBee network is called a Personal Area Network (PAN).
This section describes PAN IDs, extended PAN IDs, and channels, all concepts which define a single ZigBee network. Application examples are given which show how to adjust these settings in a ZigBee environment.
