No WLAN engineer's tool box is complete without spectrum and protocol analyzers. Here's why.We’ve come a long way since Netstumber and Kismet were the all-purpose tools for identifying, and in some cases surveying and troubleshooting, Wi-Fi networks. These days, network engineers and administrators have a wide range of options, from freeware to very expensive enterprise tools. What’s in your Wi-Fi tool box? What needs to be there?
In my opinion, you need two categories of products for everyday use: spectrum analyzers and protocol analyzers. That’s because Wi-Fi operates at two layers in the OSI model, the physical layer and the data layer. Specific tools are required to interact with each of these layers.
The physical layer takes information from the upper layers in the OSI model and transforms data into bits. These bits are transmitted differently depending on the medium and modulation used...
