Specific expertise and training required for professional installers
To ensure that the ePMP 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 an ePMP
system for operation in the 5 GHz band (5150 – 5250 MHz – FCC only, 5250 – 5350 MHz, 5470 – 5725
MHz and 5725 – 5850 MHz).
Avoidance of weather radars
The installer must be familiar with the requirements in FCC KDB 443999. Essentially, the installer
must be able to:

Access the FCC database of weather radar location and channel frequencies.
 Use this information to correctly configure the product (using the GUI) to avoid operation on
channels that must be avoided according to the guidelines that are contained in the KDB and
explained in detail in this user guide.
In ETSI regions, the band 5600 MHz to 5650 MHz is reserved for the use of weather radars.
External antennas
When using a connectorized version of the product (as compared to the version with an integrated
antenna), the conducted transmit power must 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 antenna cable losses.
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
are entered into the GUI.
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 ePMP can be found in section
System planning on page 90 .
Training
The installer needs to have basic competence in radio and IP network installation. The specific
requirements applicable to the ePMP must be gained by reading this user guide and by performing
sample setups at base workshop before live deployments.
