What
is
Hub
Site
Synchronization
(HSS)
When
several
radios
are
collocated
at
a
common
hub
site,
interference
may
occur
from
one
unit
to
another.
RADWIN
ODUs
support
the
collocation
of
more
than
two
units
at
a
central
site.
Like
any
other
RF
deployment,
the
wireless
operation
is
highly
dependent
on
factors
such
as
available
frequencies,
the
physical
spacing
between
radios,
other
third
party
interfering
radios,
and
whether
other
RADWIN
radios
are
installed.
RADWIN
HSS
The
RADWIN
HSS
method
uses
carries
pulses
sent
to
each
ODU,
which
synchronize
their
transmission
with
each
other.
The
pulse
synchronization
ensures
that
transmission
occurs
at
the
same
time
for
all
collocated
units.
This
also
results
in
all
of
the
hub
site
units
receiving
data
at
the
same
time,
eliminating
the
possibility
of
interference
that
could
result
if
some
units
transmit
while
other
units
at
the
same
location
receive.
illustrates
interference
caused
by
non
‐
synchronized
collocated
units.
Note
HSS
does
not
eliminate
the
need
for
careful
RF
planning
to
ensure
the
design
will
work
as
planned.
