Manual Site Surveys

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 signals 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?

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.

Onsite Site Surveys / 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.

Our surveys start with temporarily mounting the same access points and antennas that will be permanently installed. We then use professional-grade software to test not only for signal strength, but Signal-to-Noise ratio (SNR) to test the signal's viability, interference and data rates. Our thorough approach is the most accurate solution available.
