PAN
© 2007 Digi International, Inc.
A node that has the unique function of forming a network. The
coordinator is responsible for establishing the operating channel and
PAN ID for an entire network. Once established, the coordinator can
form a network by allowing routers and end devices to join to it.
Once the network is formed, the coordinator functions like a router
(it can participate in routing packets and be a source or destination
for data packets).
Refer to the XBee Series 2 coordinator section for more information.
A node that creates/maintains network information and uses this
information to determine the best route for a data packet. A router
must join a network before it can allow other routers and end
devices to join to it.
A router can participate in routing packets and is intended to be a
mains-powered node.
Refer to the XBee Series 2 router section for more information.
End devices must always interact with their parent to receive or
transmit data. (See ‘joining definition.) They are intended to sleep
periodically and therefore have no routing capacity.
An end device can be a source or destination for data packets but
cannot route packets. End devices can be battery-powered and offer
low-power operation.
Personal Area Network - A data communication network that
includes a coordinator and one or more routers/end devices.
-- Several end devices can operate in one PAN
-- Can be a data packet source and destination
-- All messages are relayed through a coordinator or router
-- Lower power modes
-- One coordinator per PAN
-- Establishes/Organizes PAN
-- Can route data packets to/from other nodes
-- Can be a data packet source and destination
-- Mains-powered
-- Several routers can operate in one PAN
-- Can route data packets to/from other nodes
-- Can be a data packet source and destination
-- Mains-powered
