For
efficient
handover
of
conversations
between
base
stations,
deploy
repeaters
with
sufficient
overlap
of
radio
coverage.
Coverage
overlap
occurs
when
the
radio
fields
of
base
station
and
repeaters
overlap
each
other.
Base
station
and
repeaters
must
be
placed
in
such
a
way
that
the
radio
coverage
from
one
base
station
to
a
repeater
overlaps
by
30
to
45
feet/10
‐
15
meters.
Overlaps
are
necessary
to
give
the
handset
time
to
do
a
handover
to
a
base
station
or
repeater
from
which
it
receives
a
better
signal
quality.

Coverage
overlap
‐
If
the
overlap
area
is
not
enough
‐
less
than
30
–
45
feet/10
‐
15
meters
there
is
a
risk
of
the
connection
being
dropped
while
moving
from
one
coverage
area
to
another.
However,
too
much
overlap
results
in
a
wasted
coverage
area.
‐
Base
stations
and
repeaters
are
omni
‐
directional,
which
means
that
the
RF
signal
is
propagated
vertically
and
horizontally
from
the
base
stations
and
repeaters.
Depending
on
building
materials
the
base
station
or
repeater
coverage
area
will
typically
extend
to
more
than
one
floor
of
a
structure.
‐
The
handset
will
not
necessarily
switch
over
to
the
base
station
or
repeater
from
which
the
strongest
signal
is
received.
The
handset
will
remain
connected
to
a
base
station
or
repeater
as
long
as
the
quality
of
the
received
signal
is
acceptable.
‐
Different
weather
conditions
can
influence
radio
coverage.
For
example,
a
wet
roof
or
wall
can
act
as
a
shield.
Also,
new
leaves
on
trees
in
the
spring
might
affect
the
radio
coverage
of
base
stations
and
repeaters.
‐
If
the
construction
materials
of
the
building
contain
metal,
signal
reflection
may
occur.
When
signal
reflections
occur,
the
signal
may
be
affected
even
when
the
handset
is
very
close
to
the
base
station.
You
should
document
these
areas
with
the
help
of
the
customer.
If
you
are
aware
of
metal
in
the
building
construction,
you
have
to
carry
out
a
very
thorough
site
survey.
‐
The
repeater
does
not
add
channels,
it
only
adds
additional
coverage
area.
