Important regulatory information

Specific expertise and training for professional installers

To ensure that the PTP 550 is installed and configured in compliance with the requirements of
Industry Canada and the FCC, installers must have the radio engineering skills and training
described in this section. This is particularly important when installing and configuring a PTP
550 system for operation in the 5.1 GHz and 5.4 GHz UNII bands.

External antennas

When using a connectorized version of the product (as compared to the version with an
integrated antenna), 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 ranges 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.

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 de 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.

Ethernet networking skills

The installer must have the ability to configure IP addressing on a PC and to set up and control
products using a web browser interface.

Lightning protection

To protect outdoor radio installations from the impact of lightning strikes, the installer must be
familiar with the normal procedures for site selection, bonding and grounding. Installation
guidelines for the PTP 550 can be found in
Chapter 2: System hardware
and
Chapter 5:
Installation.
