Many supposed WiFi professionals simply install a Wireless Access Point (WAP) near the center of your facility and guess how the coverage will be throughout. Then as complaints of no-access filter in, they just add another WAP to that area then the next, then the next… Add up all that time and expense of equipment and you’ve probably spent more than what is necessary and without full coverage! Here at Techspert, we highly recommend hiring us to perform a comprehensive WiFi Site Survey (WSS).
Site surveys are pertinent because of unpredictable radio frequency propagation and the fact that you cannot just guess the performance outcome of a WiFi network with so many variables affecting it. Taking into account the large proliferation of WiFi infrastructure, interference from nearby WiFi networks (WLANs) is a key factor making a proper site survey necessary.
We start with a scale drawing of your facility. We walk all necessary boundaries of your WiFi coverage requirements and using sophisticated software and a recommended WAP, we analyze the following areas that make up a WiFi network (WLAN):
Our next step is to take a closer look at the interference, both SNR and SIR, to determine the best locations and channels to use for optimizing your WLAN. We use another sophisticated piece of software to visualize the interference.
Armed with all these solved variables, we can very accurately determine how many access points are necessary for full coverage, where to install them, and what channels to configure each for optimal WiFi access.
