Radio Node - A PC, notebook computer, etc. containing a
Wireless LAN ISA, MCA card or PCMCIA Adapter.
End Node - A Radio Node that is at the end of the RF
Network Tree.
Understanding the Radio Network
Advanced Radio Local Area Network (ARLAN) is designed
like an upside-down tree, with a Root Unit at the top, and
repeaters and Radio nodes branching down and out from
the Root as shown in the figure below.
Wireless Access Points can serve as a Root Unit or Re-
peater, providing wireless data communications between
the Ethernet based network and other end nodes, or within
the radio network itself.
In the example shown,
the Root Unit does not
register, but will accept
Registration from those
nodes within Radio
Range (The Repeater)
The Repeater registers to
the Root Unit and will
accept registrations from
the End Nodes within
radio range.
The Repeater will pass
along the End Nodes’
registrations to its parent,
the Root Unit.
