A site survey is important. Before installing WLAN access points, Figure
illustrates
things that should be investigated about the customer facility. A good site
survey will help determine the following:
- Feasibility of the desired coverage
- Radio frequency interference
- Wired connectivity limitations
A site survey will allow the customer to properly install the WLAN and
have consistent, reliable wireless access. A WLAN site survey engineer should
be knowledgeable on both the wireless and wired equipment.
A site survey
will help the customer determine how many APs will be needed throughout the
facility to provide the desired coverage. It will also determine the placement
of those APs and detail the necessary information for installation. A site
survey will also determine the feasibility of the desired coverage in the face
of obstacles such as wired connectivity limitations, radio hazards, and
application requirements. This will allow the WLAN to be properly installed and
for the customer to have consistent, reliable wireless access.
The
process of performing a site survey includes the following steps:
- Gather tools and configuration.
- Research and investigate industry specific concerns.
- Gather the recommended equipment list, or site survey kit.
- Implement the site survey.
- Document the site survey.
