IMPORTANT REGULATORY INFORMATION
The ePMP product is certified as an unlicensed device in frequency bands where it is not allowed
to cause interference to licensed services (called primary users of the bands).
Radar avoidance
In countries where radar systems are the primary band users, the regulators have mandated
special requirements to protect these systems from interference caused by unlicensed devices.
Unlicensed devices must detect and avoid co-channel operation with radar systems.
The ePMP provides detect and avoid functionality for countries and frequency bands requiring
protection for radar systems.
Installers and users must meet all local regulatory requirements for radar detection. To meet these
requirements, users must set the correct country code during commissioning of the ePMP
equipment. If this is not done, installers and users may be liable to civil and criminal penalties.
Contact the Cambium helpdesk if more guidance is required.
USA and Canada specific information
The USA Federal Communications Commission (FCC) has asked manufacturers to implement
special features to prevent interference to weather radar systems that operate in the band 5600
MHz to 5650 MHz. These features must be implemented in all products able to operate outdoors in
the band 5470 MHz to 5725 MHz.
Manufacturers must ensure that such radio products cannot be configured to operate outside of
FCC rules; specifically it must not be possible to disable or modify the radar protection functions
that have been demonstrated to the FCC.
In order to comply with these FCC requirements, Cambium supplies variants of the ePMP for
operation in the USA or Canada. These variants are only allowed to operate with license keys and
country codes that comply with FCC/IC rules. In particular, operation of radio channels overlapping
the band 5600-5650 MHz is not allowed and these channels are permanently barred.
In addition, other channels may also need to be barred when operating close to weather radar
installations.
