PMP 450i and PTP 450i Configuration and User Guide Contents
RF exposure near the antenna
Radio frequency (RF) fields is present close to the antenna when the transmitter is
on. Always turn off the power to the unit before undertaking maintenance activities
in front of the antenna.
Minimum separation distances
Install the AP or SM so as to provide and maintain the minimum separation
distances from people.
The minimum separation distances for each frequency variants are specified in the
PMP 450i Planning Guide.
Important regulatory information
The PMP 450i 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 region code during
commissioning of the PMP 450i. 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 450i for operation in the USA or Canada. These variants are only allowed to
operate with region codes that comply with FCC/IC rule.
The list of FCC and Canada approved antennas for operation with the
PMP 450i/PTP 450i is provided in Appendix B.
