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. Page 2 Legal and Open Source Guide 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. 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 the 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:

Register the installation on http://spectrumbridge.com/udia/home.aspx. Make 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. 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. Page 3 Legal and Open Source Guide 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 prsent appareil est conforme aux CNR d'Industrie Canada applicables aux appareils radio exempts de licence. L'exploitation est autorise aux deux conditions suivantes :

(1) l'appareil ne doit pas produire de brouillage, et

(2) l'utilisateur de l'appareil doit accepter tout brouillage radiolectrique subi, mme si le brouillage est susceptible d'en compromettre le fonctionnement. ISEDC a demand aux fabricants de mettre en uvre des mcanismes spcifiques pour viter dinterfrer avec des systmes radar fonctionnant dans la bande 5600 MHz 5650 MHz. Ces mcanismes doivent tre mis en uvre dans tous les produits capables de fonctionner l'extrieur dans la bande 5470 MHz 5725 MHz. Les fabricants doivent s'assurer que les produits de radiocommunications ne peuvent pas tre configurs pour fonctionner en dehors des rgles ISEDC, en particulier, il ne doit pas tre possible de dsactiver ou modifier les fonctions de protection des radars qui ont t dmontrs ISEDC. Afin de se conformer ces exigences de ISEDC, Cambium fournit des variantes du 450 Platform Family exclusivement pour le Canada. Ces variantes ne permettent pas lquipement de fonctionner en dehors des rgles de ISEDC. En particulier, le fonctionnement des canaux de radio qui chevauchent la bande 5600-5650 MHz est interdite et ces canaux sont dfinitivement exclus. ISEDC Approved Antennas The list of antennas used to obtain ISEDC approvals is provided in section Reference Information of 450 Platform Configuration Guide. Page 4 Antennas externes Legal and Open Source Guide Lorsque vous utilisez une version du produit sans antenne intgre, il peut tre ncessaire de rduire la puissance d'mission pour garantir que la limite rglementaire de puissance isotrope rayonne quivalente

(PIRE) n'est pas dpasse. L'installateur doit avoir une bonne comprhension de la faon de calculer le gain de l'antenne relle et les pertes dans les cbles de connections. La plage de valeurs admissibles pour un gain maximal de l'antenne et des pertes de cbles 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 mene correct afin de s'assurer qu'il ne soit pas possible pour l'installation de dpasser la limite PIRE, lorsque les valeurs appropries pour le gain d'antenne et les pertes de cbles d'alimentation sont entres dans linterface utilisateur.

ICNIRP (International Commission on Non-Ionizing Radiation Protection) guidelines for the general public. See the ICNIRP web site at https://www.icnirp.org/cms/upload/publications/ICNIRPemfgdl.pdf and Guidelines for Limiting Exposure to Time-Varying Electric, Magnetic, and Electromagnetic Fields. Power density exposure limit Install the radios for the 450 Platform Family of wireless solutions so as to provide and maintain the minimum separation distances from all persons. The applicable FCC power density exposure limit for RF energy in the 3, 4.9, 5.4 and 5.8 GHz frequency bands is 10 W/m2 and in 900 MHz frequency band is 6 W/m2. For more information, see Human exposure to radio frequency energy on page 31. The applicable ISEDC power density exposure limit for RF energy in unlicensed bands is 0.02619 * (f^(0.6834)), where f is the lowest frequency of the supported band. For licensed bands, the power density exposure limit is 0.6455 * (f^(0.5)), where f is the lowest frequency of the supported band. Page 31 Calculation of power density Legal and Open Source Guide The following calculation is based on the ANSI IEEE C95.1-1991 method, as that provides a worst-case analysis. Details of the assessment to EN50383:2002 can be provided, if required. Peak power density in the far field of a radio frequency point source is calculated as follows:

These are conservative distances that include compliance margins. At these and greater separation distances, the power density from the RF field is below generally accepted limits for the general population. 450 Platform Family ODU adheres to all applicable EIRP limits for transmit power when operating in MIMO mode. Separation distances and compliance margins include compensation for both transmitters. Explanation of terms used in the following tables:

The regulations require that the power used for the calculations is the maximum power in the transmit burst subject to allowance for source-based time-averaging. At 5.4 GHz and EU 5.8 GHz, the products are generally limited to a fixed EIRP which can be achieved with the Integrated Antenna. The calculations above assume that the maximum EIRP allowed by the regulations is being transmitted. Remarque Gain de l'antenne en dBi = 10 * log(G). Les rglements exigent que la puissance utilise pour les calculs soit la puissance maximale de la rafale de transmission soumis une rduction pour prendre en compte le rapport cyclique pour les signaux moduls dans le temps. Pour une opration dans la CEE dans les bandes 5,4 GHz et 5,8 GHz, les produits sont gnralement limits une PIRE qui peut tre atteinte avec l'antenne intgre. Les calculs ci-dessus supposent que la PIRE maximale autorise par la rglementation est atteinte. Note If there are no EIRP limits in the country of deployment, use the distance calculations for FCC 5.8 GHz for all frequency bands. At FCC 5.8 GHz, for antennas between 0.6m (2ft) and 1.8m (6ft), alter the distance proportionally to the antenna gain. Remarque Si aucune limite de PIRE existe pour le pays de dploiement, utilisez les calculs de distance pour FCC 5,8 GHz pour toutes les bandes de frquence. Pour la band FCC 5,8 GHz et les antennes entre 0,6 m (2 pieds) et 1,8 m (6 pieds), modifier la distance proportionnellement au gain de l'antenne.
