Maximum Number of Children: The total number of children that can be associated with a single Network device. The
current profile limit is 20; comprising of up to 6 Routers and 14 End Devices.
Mesh Network: An interconnection of nodes where nodes are permitted to transmit data directly to any other node.
Neighbor Table: A table used by the Coordinator and Router(s) to keep track of other devices operating in the same
coverage area.
Network Address: The unique 16-bit address assigned to a device upon joining a PAN. This address is used for
routing messages between devices and can be different each time a device is powered on. The Network Coordinator
will always
have a Network Address of 0x0000. Note that addresses are not assigned in numerical order.
Operating Channel: The specific frequency selected for data communications. The operating channel is determined
by the Coordinator on power-up.
Orphan Device: A device which has lost communication contact with or information about its Parent device.
PAN: Personal Area Network. Includes a Network Coordinator and one or more Routers/End Devices. The Network
formation is determined by the Maximum Network Depth, Maximum Number of Routers, and Maximum Number of
Children.
PAN ID: Similar to a Network ID. Devices which are operating with different PAN ID’s will not be associated to the
same network.
Parent/Child: When a device joins the Network, it becomes a child of the device with which it is associated. Similarly,
the device with which it associated becomes its parent device. Network devices can have multiple children, but only
one parent. End Devices cannot be parents and are always children of the Coordinator or a Router. The Coordinator
does not have a parent device.
POS: Personal Operating Space. The area within reception range of a specific device.
Profile: A collection of device descriptions, which together form a coorperative application. Devices utilizing different
profiles will only support very basic inter-communications. The ZB2430 uses a private profile as specified by
Aerocomm.
RFD: Reduced Function Device. The End Device is an example of an RFD.
Route Discovery: An operation using RREQ and RREP’s in which a ZigBee Coordinator or Router discovers a route to
a device outside its POS.
Route Reply (RREP): A ZigBee command used to reply to a Route Request command.
