The ZigBee network structure and ultimate size are specified by Stack profiles. The Stack profiles define the maximum number of Layers, maximum number of Children per Parent, & maximum number of Routers that can be Children. These parameters are set during code compilation and cannot be altered after compilation. The ZB2430 uses the restricitions specified by the Home Lighting & Controls profile.

The ZigBee Coordinator determines the maximum number of children any device within its network is allowed. Of these children, a maximum number can be router-capable devices; while the remainder shall be reserved for end devices. Each device has an associated depth which indicates the minimum number of hops a transmitted packet must travel to reach the ZigBee Coordinator (see Figure 3: "Network Depth" on page 15).

The Coordinator has a depth of zero and its Children have a depth of 1. Maximum Network Depth specifies the maximum number of hops (Routers) that a node can be away from the Coordinator. The Home Lighting & Controls profile limits the maximum network depth to 5.
