PMP 450 Planning Guide
Site planning
This section describes factors to be taken into account when choosing sites for the AP or SM, power supplies,
CMM4 (if applicable) and GPS antenna (if applicable).
AP or SM site selection
When selecting a site for the AP or SM, 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 3-14.
• Height and location to achieve the best radio path.
• Ability to meet the requirements specified in Grounding and lightning protection on page 1-108.
• Aesthetics and planning permission issues.
• Cable lengths; see Maximum cable lengths on page 1-67.
• The effect of strong winds on the installation; see Wind loading on page 1-68.
Power supply site selection
When selecting a site for the AP or SM power supply, consider the following factors:
• Indoor location with no possibility of condensation.
• Availability of a mains electricity supply.
• Accessibility for viewing status indicator LED and connecting Ethernet cables.
• Cable lengths; see Maximum cable lengths on page 1-67.
Maximum cable lengths
When installing PMP 450 Series APs or SMs, the maximum permitted length of the shielded copper Ethernet
interface cable is 330 feet (100m) from AP/SM to their associated power supplies or CMM4.
When receiving synchronization signalling from a UGPS module, see table below for maximum
synchronization cable lengths.
