Our Methodology
Anyone can claim
they do wireless site surveys, including those that walk
around using free utilities that check for basic signal
strength, without any training or understanding of how
wireless works. That may be fine if you only need
basic Internet connectivity, but if your network supports
mission-critical applications, you need a professional-grade
solution.
Our
methodologies are what differentiate us from our
competition. We start with the belief that combining
the best tools and training with years of experience leads
to the best wireless solutions available. Our formula for
success includes the following:
Expert
Certified Personnel
We start with
a commitment to having the best trained personnel possible.
We only employ or contract with Certified Wireless Network
Professionals (CWNP).
We are proud to be a member of the prestigious CWNE
roundtable, an exclusive committee of wireless experts
dedicated to developing the highest level and most respect
vendor-neutral certification in the wireless industry, as
well as writing technical whitepapers.
Predictive
Modeling
Predictive
models, also known as virtual site surveys allow us to
efficiently and accurately identify the number of access
points required, as well as their initial placement and
configuration. Modeling is ideal for creating "what
if" scenarios that show us the effects of changes in real
time. Our designs always start with a model which we
then validate.
RF Spectrum Analysis
Because
wireless networks operate in unlicensed frequencies,
potential interference from numerous devices such
as microwaves, cordless phones, Bluetooth devices, video
cameras, etc. can have a significant negative impact. RF spectrum analyzers are the only devices that can identify
physical-layer interference, and no onsite wireless site
survey is complete without this service.

Detailed Deliverables
Our reports
spell out the facts, and leave no doubt in the customer's
mind as to what the wireless network does or will look like.

Onsite Site Surveys\
Manual Validation
 When the
highest degree of accuracy is required for your
mission-critical applications, there is no substitute for a
professional-grade manual site survey.
Only
by thoroughly sampling for not only signal strength,
but signal-to-noise ratio, interference, along with
data rates and throughput can problems be
identified, such as dead spots, co-channel
interference from internal and external access
points, and not having enough capacity per access
point.
Without gathering the correct information and then
knowing - through extensive training and experience
- how to make the necessary adjustments or
recommendations, a wireless network design that can
reliably support latency-sensitive, mission-critical
applications is nearly impossible to achieve.
Having too many access points can be as detrimental
as having too few due to co-channel interference.
A strong signal strength means little if the noise
floor is so high the wireless devices cannot
reliably communicate, making testing a signal's
viability through SNR (signal-to-noise ratio)
critical. Even if coverage is adequate,
certain areas may overwhelm the capacity of a single
access point.
Our
pre-installation wireless site surveys
start with temporarily mounting the same access points and
antennas that will be permanently installed, as determined
through a predictive
model. Without using the same hardware that will
be permanently installed, designs can easily be based upon
false conclusions leading to unreliability.
No
site survey is complete without an
RF Spectrum
Analysis. Only RF spectrum analyzers can
identify physical layer (OSI Layer 1) sources of
interference, such as cordless phones, Bluetooth,
microwaves, etc.
Just
about everyone with a wireless card and Netstumbler
claims they can perform a wireless site survey.
Before choosing a vendor, make an educated decision
and find out what kind of tools, experience and
training will be used. Do they have a
methodology or organized approach, and what
references
can they provide?
