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,
resources,
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.
Register
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.
Although
you
configure
an
SU
PRO/AIR
from
its
Web
Interface,
you
must
register
it
using
the
RADWIN
Manager.
Resource
Type
During
the
registration
process,
you
determine
the
resource
type
for
each
HSU
a
.
This
can
be
Best
Effort
(BE),
where
traffic
is
passed
according
to
available
bandwidth,
or
Committed
Information
Rate
(CIR),
where
a
guaranteed
bandwidth
is
allotted
to
the
HSU.
MIR
For
each
registered
HSU,
you
can
set
separately,
the
uplink
and
downlink
Maximum
Information
Rate
(MIR)
in
Mbps
or
leave
it
as
Unlimited
.
Connection
Table
You
may
also
manage
an
HSU
Connection
table
to
enable
and
disable
connectivity
between
HSUs
in
a
sector.
Nomadic
HSUs
may
be

or

and
across

Disable
To
disable
an
HSU
you
must
deregister
it.
(A
suspend
mechanism
is
also
available,
to
suspend
service
on
an
HSU
for
a
limited
period.)
