Scope
of
this
Chapter
This
chapter
describes
what
is
hub
site
synchronization,
why
it
is
needed,

the

9.2
What
is
Hub
Site
Synchronization
(HSS)?
When
several
radio
units
are
co
‐
located
at
a
common
site,
interference
may
occur
from
one
unit
to
another.
This
interference,
if
it
occurs,
happens
when
at
a
given
moment
in
time
one
unit
is
transmitting,
but
the
other
is
receiving:
the
receiving
unit
may
detect
the
transmitting
signals
of
its
immediate
neighbor
instead
of
(or
in
addition
to)
signals
from
where
it
should.
illustrates
interference
caused
by
non
‐
synchronized
co
‐
located
units:
If
Unit1
is
receiving
at
a
given
moment
from
Unit1A,
and
at
that
same
moment
Unit2
is
transmitting
to
Unit2A,
Unit1
might
receive
signals
directly
from
Unit2.
