Working With Nomadic Hsus; Workflow - Radwin 5000 HPMP User Manual

Working with Nomadic HSUs
As soon as the HSUs are configured to your satisfaction, you must register them on the HBS.
Registration of an HSU enables service traffic between the HSU and the HBS. The HBS keeps
track of registered HSUs by maintaining a table of their MAC addresses. Registered fixed HSUs
set an internal flag so that they cannot register simultaneously to more than one HBS.
During the registration process, you assign time slots to each HSU. A total of 63 time slots are
available to each HBS in each of the uplink and downlink directions, to be distributed among
the HSUs in the sector. The relative number of time slots determines the relative amount of
service each HSU will receive. Each HSU receives at least two time slots. To disable an HSU
you must deregister it. (A suspend mechanism is also available, to suspend service on an HSU
for a limited period.)
For each registered HSU, you can set separately, the uplink and downlink Maximum
Information Rate (MIR) in Mbps or leave it as Unlimited.
You may also manage an HSU Connection table to enable and disable connectivity between
HSUs in a sector.
HSUs may be fixed or nomadic. The latter may be move around within and across sectors.
Mobile HSUs (HMUs) may also move around within and across sectors. They are covered in
Chapter 11.
Working with Nomadic HSUs
Each nomadic HSU is allocated to one of four HBS levels labelled A, B, C and D. Some
operating parameters for each level (such as VLAN, MIR, QoS, time slots, fixed rate, Spatial
Multiplexing/Diversity antenna mode) can be different for each level allowing for broad
prioritization of service between different types of nomadic units. This requires that each
nomadic HSU be assigned a level to join a sector.
A nomadic HSU may only send and receive service traffic while stationary. A nomadic HSU
detects that it is time to seek the another HBS upon sync loss. Upon entering and stopping in
a new sector, it may take several seconds to establish sync with the sector HBS.
Changing any of VLAN, MIR, QoS, fixed rate, Spatial Multiplexing/Diversity antenna mode for
one configured HSU at a given level, changes all other HSUs at that level. If you add a new
HSU to a sector (by direct connection) at a given level, at sync time, it will acquire the existing
parameters for that level.

Workflow

In this chapter, we assume that you are familiar with the graphical user interface described in
Chapter 5, including Geographic location. We will concentrate here on sector radio setup
workflow. To this end, the installation will be carried out against a blank white background. At
the end of the process we will complete the sector by opening the map to reflect our
Geographic positioning data.
Prior to commencing, you should have a written sector plan along the lines of Table
