On Friday I was having a frustrating experience with our wifi system, a nifty setup from Extricom. Ping round-trips were varying widly but always going back from a 1 s to a sub-10 ms elapsed time. I ran ping for a bit, pushed the data through R and was extremely surprised by the results. Since this particular setup uses a controller that allows seamless hand-over from one access point to another, I suppose that my bits are being transmitted by different access points at least every second. A pleasant graph nonetheless. [caption id="attachment_82" align="alignnone" width="509" caption="Latency (ms) of sequential 1-second pings"] [/caption]
