Nokia RoofTop™ Wireless Routing Installation Guide 7
Site Analysis
3.
Determine the RF paths between the antenna at the site and the
antennas at adjacent sites. For a directional link with a single antenna,
there is only one RF path. For an omnidirectional antenna, determine
all RF paths. The RF path can be determined by knowing the relative
bearing from the current site to adjacent sites.
4.
The feasibility of an RF link can be estimated based on:
• Distances between the potential sites
• The line of sight for the RF paths
• Antenna RF gains
• Cable losses
5.
After one or more sites have been installed and are operational, test
each new site before completing the installation.
6.
After determining the feasibility of the RF link, consider the
following:
• Hardware and tools necessary to complete the installation
• Wireless router installation location
• The RF cable routing between the wireless router and the antenna
• Power for the wireless router
• Ethernet cable routing
• Antenna grounding and lightning arrestor requirements
