A Little Terminology Chapter 1

A
link then, consists of two sites .
In Broadband Wireless terminology, the local and remote sites are some-
times referred to as “near” and “far”, “HQ” and “remote” and so on.
The site which is closer to the network core (often the local site) will be
referred to as
site A , and the opposite side of the link, usually closer to the
end user, as
site B .
This choice is application-neutral and will be used throughout the manual
both to describe the sites and their names as in the examples.
The link is configured and managed using a PC, the
managing computer
connected to site A. (The precise requirements for the managing computer
are set out in chapter 3, Hardware Installation).
RADWIN 1000/2000 supports three connection methods for the managing
computer:
•
Local - a direct peer to peer connection between the Ethernet ports
on the managing computer and the IDU or PoE device. Local con-
nection is always read-write.
•
Network - the managing computer and the site A IDU or PoE
device belong to a LAN and communicate through a router or hub
•
Over-the-air - the managing computer connects to site B via the
air interface
The managing computer may be connected to the link through an IDU or a
PoE device. In what follows, where ever we refer to an IDU it includes PoE
devices unless stated otherwise. Typically, if we need to refer to an IDU as
such, we will use a model name such as IDU-C.
