Perform Path Planning Studies
Path planning services is an essential part of an outdoor wireless solution
providing an accurate account of items and budgetary costs required for the
project. A Site Audit should be performed to collect GPS, obstruction, and
existing structure data. This data supplies the RadioLinx Application Engineer
pertinent information to provide a summary report for each site and path. The
path planning report is generated indicating a complete radio bill of materials,
antenna types, gain, height, tilt angle and location requirements, calculated fade
margins, and a graphical path profile for each site and network topological terrain
map. The report will also assist system integrators with initial design
specifications for testing and verifying each path link.
The following questions should be answered during path planning studies:
What tools are available to determine link quality?
How is path terrain visualized?
What are the Line-of-Sight (LoS) obstructions?
What types of antennas will be required?
How high will antennas need to be mounted and will an antenna mast or
tower be required?
Are there antenna height restrictions?
5.3.1 Sample Path Study
A Path Study or Terrain Analysis is the initial step in the configuration of an RF
network. It can be used for evaluation before an Onsite Survey is performed and
can be considered as a proof of concept. A path study does not guarantee RF
links. Man made objects such as buildings, towers and highways, trees and other
foliage may not be displayed or calculated with the Path Study Report unless
otherwise identified. These obstructions to RF line-of-site need to be considered
during a site audit. Any obstructions within the RF path should be accounted for
by providing the locations and height. The following information provides the user
with recommended antenna height AGL and path profile of each site from the
base location. Make sure antennas are above buildings, trees, foliage, and other
obstructions.
