A site survey is a physical survey of the customer's premises to identify
the best possible locations to install access points to ensure 100% wireless
coverage, along with maximum performance, within the desired area.
When considering the use of wireless equipment, it is extremely difficult to
predict the propagation of radio waves and detect the presence of
interfering signals without the use of specialized test equipment. Even if
you are using omni-directional antennas, radio waves do not travel the same
distance in all directions. Walls, doors, elevator shafts, people, and other
obstacles offer varying degrees of attenuation, which cause the radio
frequency (RF) radiation pattern to be irregular and unpredictable. As a
result, one should have an RF site survey performed to understand fully the
behavior of radio waves within a facility before installing any wireless
The goal of an RF site survey is to gather enough information and data to
determine the number and placement of access points that will provide the
coverage required. Coverage required usually means the support of a minimum
data rate in a given area. An RF site Survey will also detect the presence
of radio interference coming from other sources that could degrade the
performance of the wireless LAN.
The need and complexity of an RF site survey will vary depending on the size
of the facility and the work that is to be accomplished. A site survey is a
good idea for the use of any wireless device because without a survey, users
could end up with inadequate coverage and suffer from low performance in
some areas. The purchase of wireless equipment is no small expenditure, so
it is best not to leave any portion of the project up to chance.
To ensure the accuracy of the final site survey report that WirelessTEK
delivers, only the latest and most sophisticated equipment is used. Handheld
Spectrum Analyzers are used as a guiding tool to begin the survey.
Afterwards, actual equipment is tested and retested, and then finally the
report is generated with the consulting of the facility manager for current
or future plans.
After the site survey, WirelessTEK will design the network infrastructure
to fit your specific needs. Using the information obtained during the site
survey, Wireless Builders will design a network for your specific
environment that will ensure complete propagation to each of your devices.
Having installed networks in freezers operating at -45° F, no challenge will
Placement of access points is a crucial decision as it can cut the number of
access points you need in your facility, as well as make sure that highly
trafficked areas are covered properly. You would not want to be giving a
presentation in the company board room when the network all of the sudden
goes down or hits a glitch and becomes remarkably slow. With the level of
expertise our technicians have, they will locate these hot spots, and make
sure the coverage provided in these areas takes into account their high
level of priority and importance.
Most areas in your building will actually be served by more than one access
point, so if an access point should go down for any period of time, the
network connection will automatically be transferred to a running access
point, nearly undetected by the user.
WirelessTEK will install your wireless network, test and certify its
operation. At completion, the installation will be documented for future
The installation phase is the most physically demanding phase of the
project. Using the survey report, the installation should be a smooth
process. The access points and antennas will be installed in the facility
using the marked up drawing made after the site survey. Usually, the higher
the access points and antennas are mounted, the better the signal will
Some of the activities that will take place during the installation include
butt are not limited to:
· Mounting of access points
· Installation of NEMA enclosures on case-by-case basis
· Mounting of antennas
· Connection of antennas to access points
· Connection of Backbone LAN to access points
· Connection of power to access points
· Installation and connection of remote power system
· Verification of coverage
· Configuration of access points and hardware to include:
· Proper firmware level
· Radio information (system ID, channel, bit rate)
· IP addresses (provided by customer)
· Verification of backbone connectivity:
· Ping access points
· Ping Hosts
All cabling and power runs should be done and tested prior to the
installation of the access points. After completing the installation,
testing for proper operation and coverage may indicate the need to move
access points and possibly use different settings. Finally, documentation on
all the system hardware and software will be provided to the IT staff as an
aid to be used when supporting the operational system
Before the actual installation, WirelessTEK will prepare all devices to
ensure all units are configured properly and are in working order.
Though Staging seems like an extra step, it is one of the most important
steps in the installation process. This extra step makes sure when the
hardware arrives at your facility, the installed access points are in
working order and will provide the proper coverage to their destinations.
Staging allows WirelessTEK to create a wireless network seamlessly allowing
your network to stay up and running without large delays in uptime.
Depending on the size of your facility and the placement of access points, a
complete wireless network could be set up in under a day.
WirelessTEK can guide your company to a successful system rollout by
providing direction and advice on current and new technologies.
By working closely with your IT department, WirelessTEK can be a valuable
resource for them to keep them informed of the newest technologies. By
making sure the technology you implement has the capability to be updated
and enhanced in the future, you can create a wireless network with the
confidence that it won't become obsolete when our technicians leave your
