radios,
including
Distribution
Nodes
and
Client
Nodes.

TerraWIN
Overview
1.2.1
Basic
Deployment
The
TerraWIN
system
consists
of
a
mesh
of
several
sites
,
where
each
site
has
radio
units,
with
each
radio
unit
being
called
a
“
node
”.
The
complete
mesh
is
called
a
“
Network
Segment
”.
•
The
nodes
in
the
sites
of
the
mesh
provide
broadband
coverage
from
the
backhaul
net
‐
work
to
the
area
that
is
to
be
served.
Each
site
usualy
consists
of
4
nodes
(radio
units),
where
each
are
installed
pointing
at
right
angles
to
the
other
(90
degrees),
so
that
all
4
cover
360
degrees
1
.
Each
of
these
nodes
is
called
a
“Distribution
Node”.
•
At
least
one
site
must
be
connected
to
the
backhaul
network.
This
site
is
called
the
POP
Site.
Other
sites
are
usually
not
connected
to
the
backhaul
network.
Wireless
traffic
is
brought
to
the
end
user
from
a
Distribution
Node
to
a
“Client
Node”
‐
an
additional
radio
unit
that
is
installed
at
the
end
customer
site,
which
communicates
with
the
closest
and
most
convenient
Distribution
Node.
1. Some
sites
may
have
fewer
than
4
nodes,
usually
at
the
edge
of
the
service
area.
Such
a
site
need
not
cover
a
full
360
degrees.
Some
sites
may
have
the
radios
installed
at
angles
different
from
90
degrees,
depending
on
the
cir
‐
cumstances.
