Caution
This device complies with Part 15 of the FCC Rules. Operation is subject to the
following two conditions:
lThis device may not cause harmful interference, and
lThis device must accept any interference received, including interference
that may cause undesired operation
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).

About This User Guide 15
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 5 GHz 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.
Avoidance of weather radars (USA only)
To comply with FCC rules (KDB 443999: Interim Plans to Approve UNII Devices Operating in the 5470 -
5725 MHz Band with Radar Detection and DFS Capabilities), units which are installed within 35 km (22
miles) of a Terminal Doppler Weather Radar (TDWR) system (or have a line of sight propagation path to
such a system) must be configured to avoid any frequency within +30 MHz or –30MHz of the frequency of
the TDWR device. This requirement applies even if the master is outside the 35 km (22 miles) radius but
communicates with outdoor clients which may be within the 35 km (22 miles) radius of the TDWRs. If
interference is not eliminated, a distance limitation based on line-of-sight from TDWR will need to be used.
Devices with bandwidths greater than 20 MHz may require greater frequency separation.
When planning a link in the USA, visit http://spectrumbridge.com/udia/home.aspx, enter the location of
the planned link and search for TDWR radars. If a TDWR system is located within 35 km (22 miles) or has
line of sight propagation to the PTP device, perform the following tasks:
lRegister the installation on http://spectrumbridge.com/udia/home.aspx.
lMake a list of channel center frequencies that must be barred, that is, those falling within +30MHz
or –30MHz of the frequency of the TDWR radars.
The 450 Platform Family AP must be configured to not operate on the affected channels.

About This User Guide 16
Canada specific information
Caution
This device complies with ISEDC ’s license- exempt RSSs. Operation is subject to the
following two conditions:
(1) This device may not cause interference; and
(2) This device must accept any interference, including interference that may cause undesired
operation of the device.
ISEDC 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 ISEDC
rules; specifically it must not be possible to disable or modify the radar protection functions that have
been demonstrated to ISEDC .
In order to comply with these ISEDC requirements, Cambium supplies variants of the 450 Platform Family
for operation in Canada. These variants are only allowed to operate with license keys that comply with
ISEDC rules. In particular, operation of radio channels overlapping the band 5600MHz to 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.
Other variants of the 450 Platform Family are available for use in the rest of the world, but these variants
are not supplied to Canada except under strict controls, when they are needed for export and deployment
outside Canada.
Renseignements specifiques au Canada
Attention
Le présent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio
exempts de licence. L'exploitation est autorisée aux deux conditions suivantes :
(1) l'appareil ne doit pas produire de brouillage, et
(2) l'utilisateur de l'appareil doit accepter tout brouillage radioélectrique subi, même si le
brouillage est susceptible d'en compromettre le fonctionnement.
ISEDC a demandé aux fabricants de mettre en œuvre des mécanismes spécifiques pour éviter d’interférer
avec des systèmes radar fonctionnant dans la bande 5600 MHz à 5650 MHz. Ces mécanismes doivent être
mis en œuvre dans tous les produits capables de fonctionner à l'extérieur dans la bande 5470 MHz à 5725
MHz.
Les fabricants doivent s'assurer que les produits de radiocommunications ne peuvent pas être configurés
pour fonctionner en dehors des règles ISEDC, en particulier, il ne doit pas être possible de désactiver ou
modifier les fonctions de protection des radars qui ont été démontrés à ISEDC.
Afin de se conformer à ces exigences de ISEDC, Cambium fournit des variantes du 450 Platform Family
exclusivement pour le Canada. Ces variantes ne permettent pas à l’équipement de fonctionner en dehors

About This User Guide 17
des règles de ISEDC. En particulier, le fonctionnement des canaux de radio qui chevauchent la bande
5600-5650 MHz est interdite et ces canaux sont définitivement exclus.
ISEDC Approved Antennas
The list of antennas used to obtain ISEDC approvals is provided in section Reference Information of 450
Platform Configuration Guide.
Antennas externes
Lorsque vous utilisez une version du produit sans antenne intégrée, il peut être nécessaire de réduire la
puissance d'émission pour garantir que la limite réglementaire de puissance isotrope rayonnée équivalente
(PIRE) n'est pas dépassée. L'installateur doit avoir une bonne compréhension de la façon de calculer le
gain de l'antenne réelle et les pertes dans les câbles de connections.
La plage de valeurs admissibles pour un gain maximal de l'antenne et des pertes de câbles de connections
sont inclus dans ce guide d'utilisation avec un exemple de calcul. L'interface utilisateur du produit applique
automatiquement la limite de puissance menée correct afin de s'assurer qu'il ne soit pas possible pour
l'installation de dépasser la limite PIRE, lorsque les valeurs appropriées pour le gain d'antenne et les pertes
de câbles d'alimentation sont entrées dans l’interface utilisateur.
Antennes approuvées par ISEDC
La liste des antennas approveés pour l’operation au Canada est founie dans le 450 Platform Configuration
Guide.
