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 (OSI Layer 1) interference, allowing network engineers to analyze, diagnose, and locate the sources and no onsite wireless site survey is complete without this service. Most WLAN management tools can only measure OSI Layer 2-7 and do not measure or analyze RF interference problems.
Without a spectrum analyzer, a consultant might report that performance is slow, but cannot report that slow performance is caused by WiFi interference, measure the effects of RF interference on specific channels of a network, or identify the type and location of sources of interference.
Our tools can not only detect interference but apply classification signatures that quickly identify the type of interferer present. We can also provide full OSI Layer 1 interference mapping to help determine which frequency bands are clear before implementing a solution such as video monitoring.
Because it was designed for use in a shared spectrum, 802.11 technology checks to see if the airwaves are sufficiently clear before transmitting messages. This means that if the airwaves are crowded with other radio signals, an 802.11 device may have trouble communicating, resulting in slow network performance and dropped connections. Intentional or non-intentional RF jammers and certain types of video cameras can completely prevent WLANs from communicating.
Before choosing a wireless vendor to perform a wireless site survey or troubleshooting, make sure they are using an enterprise-class RF spectrum analyzer. For more information, please call us today at 800-769-1132 or contact us here.
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 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.

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.
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.
