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, saving you time and money.
Radio Frequency propagation is a science. Formulas can measure how much a signal will attenuate (through free space path loss) in open space depending on wavelength, frequency and distance.
We can also measure how various construction material such as concrete block, drywall, windows, elevators, etc. affect the signal. For example, brick walls may mostly absorb a signal while metal may mostly reflect a signal. The below graphic illustrates the affect of an RF signal as it passes through material with a high extinction coefficient (absorption).
Our investment in sophisticated modeling software allows us to start with your site floor plans and assign "RF properties" to each object. We then place access points within the model with assigned frequencies, power levels, antennas, etc. From there we can see how the RF signals will propagate throughout the facility in terms of signal strength, signal-to-noise ratio, interference, data rates, and more.
As we change properties or locations of each access point, we can see how each change affects the rest of the model. This allows us to quickly and easily perform "what if" scenarios in real-time, identifying with a high level of accuracy the number of access points needed, along with their recommended placement and configuration.
Even when performing pre-implementation onsite manual wireless site surveys, we always start with a virtual site survey. The most difficult part of designing a wireless networking is the initial placement of access points. Instead of guessing, we take a purposeful and scientific approach.
Over the years, weve discovered this process saves you time and money, and provides for the best designs and implementations. For more information, please call us today at 1-800-769-1132 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.
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.
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.
