7KH1HW6WUHDP
point-to-point solution is a wireless communication link.
Typically each side of the link is comprised of an Outdoor Unit (ODU) and
antenna and an Indoor Unit (IDU) or PoE device as shown in
figure 1-4
below.
The link is managed by the SNMP-based Link Manager application.
The IDU and the ODU are connected by a CAT5e cable that carries the ser-
vice traffic and power.

The Radio Outdoor Unit (ODU)
The ODU is the radio transceiver of th
H1HW6WUHDP[
system. It supports
two radios for MIMO operation. It is available with an integrated antenna
(
Integrated Antenna ODU
) or with connectors for an external antenna
(
Connectorized ODU
).
The ODU may be mounted on a pole or a wall, and connects to the IDU or
PoE device using a CAT5e cable.
