About This User Guide
Other variants of the PTP 650 are available for use in the rest of the world, but these variants are
not supplied to the USA or Canada except under strict controls, when they are needed for export
and deployment outside the USA or Canada.
Specific expertise and training required for professional
installers
To ensure that the PTP 650 is installed and configured in compliance with the requirements of
Industry Canada and the FCC, installers must have the radio engineering skills and training
described in this section. This is particularly important when installing and configuring a PTP 650
system for operation in the 5.4 GHz UNII band.
Avoidance of weather radars
The installer must be familiar with the requirements in FCC KDB 443999. Essentially, the installer
must be able to:
•
Access the FCC data base of weather radar location and channel frequencies.
•
Use this information to correctly configure the product (using the GUI) to avoid operation on
channels that should be barred according to the guidelines that are contained in the KDB and
explained in detail in this user guide.
External antennas
When using a connectorized version of the product (as compared to the version with an integrated
antenna), the conducted transmit power may need to be reduced to ensure the regulatory limit on
transmitter EIRP is not exceeded. The installer must have an understanding of how to compute
the effective antenna gain from the actual antenna gain and the feeder cable losses.
The range of permissible values for maximum antenna gain and feeder cable losses are included
in this user guide together with a sample calculation. The product GUI automatically applies the
correct conducted power limit to ensure that it is not possible for the installation to exceed the
EIRP limit, when the appropriate values for antenna gain and feeder cable losses are entered into
the GUI.
Ethernet networking skills
The installer must have the ability to configure IP addressing on a PC and to set up and control
products using a web browser interface.
