802.11n device
PTP250 uses 802.11n encoding and radio transmission. In areas where the PTP 250
co-exists with 802.11a and 802.11n devices, the PTP 250 detects the 802.11a and
802.11n radio signals and chooses a clear channel away from any interference.
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.
