When is the last time you performed a wireless site survey? Most companies do not check their wireless network regularly. Often, wireless access points will be configured, deployed, and forgotten until a user enters a support ticket. Wireless systems can also be installed incorrectly from the beginning, without proper evaluation of the environment. The typical “evaluation” we see when purchasing a new wireless solution is a Predictive Site Survey, where a network engineer will import floor plans into a tool and draw walls on the map to give them an idea of what their coverage area will look like when the solution is deployed.
These predictive surveys do a great job at telling you where to place the AP’s, but they lack the real-world data to create the best channel plan to minimize interference with your building neighbors (for example). A wireless site survey from Zunesis is more comprehensive. There are many variables in a wireless deployment; even something as small as a microwave oven can cause interference when in use.
