Important regulatory information
The 450 Platform Family products are 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).
Application software
Download the latest 450 Platform Family software and install it in the Outdoor Units (ODUs) before
deploying the equipment. Instructions for installing software are provided in
450 Platform Planning and
Installation Guide
.
USA specific information
The USA Federal Communications Commission (FCC) requires 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.
Cambium supplies variants of the 5GHz 450, 450i, 450b, and 450m Series specifically for operation in
the USA to comply with FCC requirements (KDB 905462 D02 UNII DFS Compliance Procedures New
Rules v02). These variants are only allowed to operate with license keys that comply with FCC rules.
To ensure compliance when using PMP 450 Series and PTP 450 Series, follow the recommendation in
Avoidance of weather radars (USA only)
External antennas
When using a connectorized version of the product, 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.
