Site planning
This section describes factors to be considered when choosing sites for PMP or PTP radios, power supplies, CMM4
(if applicable) and UGPS (if applicable).
Site selection for PMP/PTP radios
When selecting a site for the ODU, consider the following factors:
•
Height and location to ensure that people are kept away from the antenna; see Calculated distances and power
compliance margins on page 4-24 .
•
Height and location to achieve the best radio path.
•
Indoor location where power supply LED indicators accessible and cable length should not exceed maximum
recommended length; see
Power supply site selection
•
Ability to meet the requirements specified in Grounding and lightning protection on page 3-8.
•
Aesthetics and planning permission issues.
•
Cable lengths; see ODU interfaces on page 2-26 .
•
The effect of strong winds on the installation; see ODU wind loading on page 3-11 .
Calculated distances and power compliance margin
The calculated minimum separation distances, recommended distances and resulting margins for each frequency
band and antenna combination. 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.
PMP/PTP 450 platform equipment adheres to all applicable EIRP limits for transmit power when operating in MIMO
mode. Separation distances and compliance margins include compensation for both transmitters.
Site planning
Power supply site selection
When selecting a site for the ODU power supply, consider the following factors:
•
Indoor location with no possibility of condensation, flooding or high humidity.
