Avoiding interference from nearby devices
At initialization, the products monitor the available frequency channels to find a channel
that is clear of interference.
Typical deployment
The PTP 250 bridge consists of a pair of identical units, one deployed at each end of the
link. The radio link operates on a single frequency channel. One unit is configured as a
master and the other as a slave. The master unit takes responsibility for controlling the
link in both directions.
The bridge is aimed at a wide range of applications. One example is an enterprise that
needs to connect together the Local Area Network (LAN) of two or more buildings as
shown in Figure 1-1.

System components
Each end of the link consists of:
• Outdoor Unit (ODU): An integrated (or connectorized) outdoor transceiver unit
containing all the radio and networking electronics.
• PoE power supply: An indoor connection box containing a mains power supply, status
indicators and network connection port.
• Cabling and lightning protection: CAT5e cables, grounding cables, connectors and
a lightning protection unit (LPU).
