Benefit of the chosen bands
The PTP 600 operates in bands that offer the dual benefits of high data throughput and
good radio propagation characteristics. The wide band of spectrum available is
subdivided into several channels such that multiple systems can operate in the vicinity
without causing interference to one another.
Similarity to 802.11a devices
The PTP 600 Series products are not 802.11a devices. Although similar, they use
different encoding and radio transmission systems from 802.11a. In areas where
802.11a systems are operating, the PTP 600 Series will detect the 802.11a radio
signals and choose a clear channel away from any interference.
Avoiding interference from nearby devices
At initialization, the PTP 600 Series
monitors the available frequency channels to find
a channel that is clear of interference. In operation, the PTP 600 Series
continuously
monitors the spectrum to ensure it is operating on the cleanest channel.
Typical deployment
The PTP 600 Series Bridge consists of an identical pair of units deployed one at each
end of the link. The radio link operates on a single frequency channel in each direction
using Time Division Duplex (TDD). One unit is deployed as a master and the other as a
slave. The master unit takes responsibility for controlling the link in both directions.
The PTP 600 Series Bridge is aimed at a wide range of applications. An example
application is an enterprise that has a requirement to connect together the Local Area
Network (LAN) of two or more buildings as shown in
