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

Working with Nomadic HSUs

During the registration process, you assign time slots to each HSU. A total of 64 time slots
are available to each HBS to be distributed among the HSUs in the sector. The relative num-
ber 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 mech-
anism 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 Infor-
mation Rate (MIR) in Mbps or leave it at Best Effort.
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 8.
Working with Nomadic HSUs
Each nomadic HSU is allocated to one of four HBS levels labelled A, B, C and D. Some operat-
ing parameters for each level (such as VLAN, MIR, QoS, time slots, fixed rate, MIMO/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, MIMO/Diversity antenna mode for one config-
ured 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 param-
eters for that level.

Workflow

In this chapter, we assume that you are familiar with the graphical user interface described in
Chapter 4, 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 Geo-
graphic positioning data.
Prior to commencing, you should have a written sector plan along the lines of
