Customer Support Chapter 1
A link then, consists of two sites .
• In Broadband Wireless terminology, the local and remote sites are sometimes referred
to as “near” and “far”, “HQ” and “remote” and so on.
The RADWIN 2000 D+ class radios achieve their 700Mbps throughput by drawing on
new technology developed for the RADWIN 5000 Point to Multipoint series. Therefore
the sites are not symmetrical. The local site referred to earlier, uses a base station radio
as the link Master ODU and the remote site uses a subscriber unit as the link Slave ODU.
The Master ODU radio is labelled RT ‐ A(HBS) and the Slave ODU labelled RT ‐ B(HSU). RT
stands for Radio Terminal.
The RT ‐ A(HBS)/RT ‐ B(HSU) and master/slave terminology will be used throughout the
manual both to describe the two link sites without further comment.
The link is normally configured and managed using a PC, the managing computer
connected to the Master ODU. (The precise requirements for the managing computer
are set out in Minimum System Requirements ). It may also be connected to the Slave
ODU either directly or over ‐ the ‐ air.
We will occasionally need to distinguish between the site to which the managing
computer is connected, and the second site, when they are not specifically RT ‐ A(HBS) or
RT ‐ B(HSU). The former will be called the managing site and the latter, the over ‐ the ‐ air
site . Which is which, is always determined by the location of the managing computer.
• Downlink traffic is data transfer from anRT ‐ A(HBS) to an RT ‐ B(HSU).
• Uplink traffic is data transfer from an RT ‐ B(HSU) to an RT ‐ A(HBS).
• RADWIN 2000 D+ 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 PoE device.
• Network ‐ the managing computer and the site A IDU or PoE device belong to a LAN
and communicate through a router or switch
• Over ‐ the ‐ air ‐ the managing computer connects to site B via the air interface
• The managing computer is connected to the link through a PoE device.
• Universal bands refer to RADWIN Universal bands.
