How Wi-Fi Roaming Really Works

We all want Wi-Fi roaming to be seamless, but that just isn’t always the case. To get a better idea of what happens when a Wi-Fi client roams, I did some testing to see what the packets and protocols really do. The actual handoff from one access point to another is generally fast, but the overall roaming process can add lots of latency to wireless applications. For details, see the tutorial that we posted.

Identifying SNR range boundaries for signal coverage

One of the most important aspects of planning the installation of wireless access points is to identify the SNR (signal-to-noise) value that defines the range boundary for signal coverage. This SNR value will provide the basis for “good” and “bad” signal coverage areas. When performing a RF site survey and testing signal coverage, you need to know the SNR value that defines the boundary so that it’s possible to determine optimum installation locations for access points. You can learn how to do this by reading our corresponding tutorial. Read More...
