Wireless facts on google video

Last week, on video.google.com, I saw a video on testing google's metro wifi network in MountainView when it was first set up (search for testing metro wifi if the URL turns out not to be stable). Among the things that I gleaned from there are the following facts:

• wifi is good for 300 ft + goes thru 1 wall well
• The testing looked for
  
• coverage (using Torius, a commercial company whose antennae were deployed in the injection layer of the network - which is an intermediate WiMax layer)
• capacity (choices were ttcp/iperf nuttcp). iperf was chosen for simplicity + #options
• LiveHttpHeader utility for firefox was also useful

And yesterday I watched a video of Van Jacobson talking about a new networking paradigm he wants to push. As with many of his papers, he has a quite unique way of looking at things. Definitely worth a watch!

Google video is proving surprisingly useful - lots of other "software engineer" type of videos are also out there; including a 2 hour introduction to python by an author of python in a nutshell and python cookbook.
