3. Site Survey

Introduction
What is Site Survey?
An RF site survey is a MAP to RF contour of RF coverage in a particular
facility. With wireless system it is very difficult to predict the propagation of
radio waves and detect the presence of interfering signals. Walls, doors,
elevator shafts, and other obstacles offer different degree of attenuation. This
will cause the RF coverage pattern be irregular and hard to predict.
Site survey can help us overcome this problem and even provide us a map of
RF coverage of the facility.
Preparation
Below are the steps to complete a simple site survey with simple tools.
1. First you will need to obtain a facility diagram, such as blueprints. This is
for you to mark and take record on.
2. Visually inspect the facility, walk through the facility to verify the accuracy of
the diagram and mark down any large obstacle you see that may affect the RF
signal such as metal shelf, metal desk, etc on the diagram.
3. Identify user's area, when doing so ask a question where is wireless
coverage needed and where does not, and note and take note on the diagram
this is information is needed to determine the number of AP required.
4. Determine the preliminary access point location on the facility diagram base
on the service area needed, obstacles, and power wall jack considerations.
Survey on Site
Step 1: With the diagram with all information you gathered in the preparation
phase. Now you are ready to make the survey.
