Why you need a WiFi Survey
WiFi Site Surveys that deliver optimum performance
Types of WiFi Survey
A Passive Survey involves an RF engineer visiting a site and using a specialist application to assess an environment. The survey application passively captures RF data from all access points in a given area and records this information for real-time or subsequent analysis. It allows the surveyor to plot heat-maps giving a visual representation of where coverage spans and if there are potential sources of interference. Some of the main design elements a passive survey can help validate are signal strength (RSSI), interference (noise), signal-to-noise ratio (SNR) and co-channel interference.
A Health Check Survey is a proactive way of ensuring that your WiFi network is working as expected and allows us to identify potential issues prior to them becoming a problem and impacting business continuity. Health check surveys require one of our engineers to attend your site and perform a walk through while taking active, passive and spectrum readings of the wireless environment. Following a Health Check Survey, we will be able to provide you with an detailed visual representation of the quality of your WiFi network.
As standard practise, Velocefi will carry out these checks during a WiFi site survey to measure and detect any adverse levels of unwanted RF interference that could affect the results and subsequent design of a surveyed network.
Interferers can come from inside a buildings structure and also bleed into a building from outside resulting in high noise floors which can affect the SNR (Signal to Noise Ratio) to its detrement.
Some common types of Interferers like Bluetooth, Microwave ovens and PIR detectors have their own signature which can be matched using the softwares signature overlays. Locating an interferer spike detected that is not immeadietly visible and obvious, can be further detected narrowing the frequency sweep and using a directional antenna to zero in on its location.
