RF exposure near the antenna
Radio frequency (RF) fields will be present close to the antenna when the transmitter is on. Always turn off the
power to the PMP 450 unit before undertaking maintenance activities in front of the antenna.
Minimum separation distances
Install the AP/SM so as to provide and maintain the minimum separation distances from all persons.
The minimum separation distances for each frequency variant are specified in Calculated distances and power
compliance margins on page 4-11.
Important regulatory information
The PMP 450 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.
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 PMP 450. 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 radar systems that operate in the 5250-5350 and 5470-5725 MHz bands. These features must
be implemented in all products able to operate outdoors in the UNII band. The use of the 5600 – 5650 MHz band is
prohibited, even with detect-and-avoid functionality implemented.
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 PMP 450 for operation in the
USA or Canada. These variants are only allowed to operate with Country Codes that comply with FCC/IC rule.
