The Maximum Number of Children specifies the total number of Children that can be connected directly to a parent
device on the current Network. The Home Lighting and Control profile specifies the maximum number of children the
Coordinator and Routers can have associated with them to be 20. Of those 20 Children, a maximum of 6 Routers can
be router-capable devices while the remainder shall be End Devices.

The IEEE 802.15.4 standard from which the ZigBee protocol was derived specifies two types of addressing modes:
• 16-bit Network Address
• 64-bit MAC Address

The Network Address is a unique address on the network. The Coordinator always has a Network Address of 0x0000
and it will assign a Network Address to each radio within its range. Routers will then assign Network Addresses to
radios within their range which have not previously been assigned an address. Because the 16-bit address is unique
to each radio on the network, an addressed packet can be sent from any radio on the network to any other radio
located anywhere on the network.
