5.2 GHz band edge channel power reduction
Equivalent isotropic radiated power (EIRP) is restricted in edge channels when the PTP 650 is
operated the 5.2 GHz band with the USA or Canada country license. The amount of EIRP reduction
has been determined during regulatory testing and cannot be changed by professional installers or
end users. Units intended for the USA and Canada market are locked for use in the USA or Canada
and cannot be operated under the regulations for other regulatory domains.
The PTP 650 takes into account the antenna gain and cable loss configured by the professional
installer in the web-based interface to limit the EIRP to ensure regulatory compliance. No
additional action is required by the installer to reduce transmitter power in band edge channels.
The maximum EIRP in band edge channels for the USA and Canada 5.2 GHz band is listed in Table
71.
