A site survey is
required for proper implementation of a wireless network. No one can
tell exactly how wireless equipment will operate in every
circumstance without a survey. This includes both in-building
wireless LANs and bridges between buildings.
This is especially
true within a building where there are hidden obstacles in the walls
or other existing wireless applications, and is equally true for
outdoor wireless links where obstacles such as trees and power lines
are involved.
Wireless surveys
analyze the conditions required to provide an optimal radio link.
The complexity of the survey depends on the nature and details of
the proposed network. These details include the physical area of the
network, factors within the building, and for outdoor bridges the
number of sites involved, the terrain and the distance between
sites.
Does the Site Qualify?
SuperUser starts
the process by discussing whether the site qualifies. Our engineers
will determine whether a wireless network is feasible, and how
complex the survey needs to be. We will discuss issues of security,
outside interference, building structure, and in the case of
long-distance outdoor wireless bridges, whether there is true line
of sight.
The Site Survey
The complexity of
the site survey required depends on which wireless solution is
proposed. A simple solution in a building is a predominantly open
space with few structural walls, or an outdoor point-to-point
wireless bridge under six miles where there is true line-of-sight
between the two locations. These require a basic site survey.
A multiple-site
indoor wireless LAN, or an indoor wireless LAN with multiple
rooms/floors and/or solid walls and unusual construction will both
require a more complex site survey. Similarly with a point-to-point
wireless bridge in excess of six miles or without true
line-of-sight.
Who should perform the Site
Survey?
A team of engineers
with expertise in LANs, Radio Frequency analysis and Antenna
Placement should perform the site survey. While many organizations
have LAN expertise, RF expertise is not so widely available.
SuperUser Solutions has a team of RF engineers and installers who
are qualified to perform complex site surveys. To assure a
successful design and implementation, it is critical that engineers
with RF expertise participate in the wireless site.
