Today we carried out our second set of field tests. This time using our new Ubiquity Nanostation2 wifi routers. In the morning Chris, Mark and John started with a radio site survey, then did a single wifi link of about 460 meters, and had a quick check of the video streaming software (mjpgstreamer) in one direction and a two-way voip call.
Curious cows. A hazard that distinguishes our field testing from our lab based testing.
Today we did our first set of antenna tests as part of the JISC funded Portable VoWLAN project. We went out into the wilds of Old Wolverton and set up a pair of Linksys WRT 54GL routers at a distance of 100 meters in the morning and then a distance of 1.3 kilometers in the afternoon, to compare the performance of a range of antenna.
We used the iperf program to identify the (tcp) bandwidth and (udp) jitter values from a 60 second test. Here’s a quick summary of the findings…
