Wireless networking is now considered a must have in nearly all industries. It’s no surprise I get a lot of comments from clients who believe they are experiencing wireless trouble in some form or fashion. They aren’t sure if it’s related to wireless controller configuration, AP placement, coverage gaps, interference, or even client machine problems. Even though Wi-Fi is nearly as prevalent as indoor plumbing, it doesn’t mean it’s always deployed properly, is reliable enough, or fast enough to address our clients needs. When something is not quite right with WIFI performance, what do I do? I’ll tell you what I do! I suggest a wireless survey and wireless assessment. Surveys are the best tool a wireless engineer has available to assist them with visualizing an invisible medium like RF. Actively scanning the frequency ranges often used for Wi-Fi as the physical location is walked is the de-facto way to record concrete data on signal, strength, interference, and a whole range of other valuable information. It’s really the only way to understand exactly what’s happening between a laptop client and the access points that dot a location.
