Wireless Research Featured in Technology Review

The "taking the Why out of Wi-Fi" research (see post below) landed on the front of the Technlogy Review page this week. Check out the story here

Taking the Why out of Wireless


"People expect WiFi to work, but there is also a general understanding that it’s just kind of flakey,” said Stefan Savage, one of the UCSD computer science professors who led development of an automated, enterprise-scale WiFi troubleshooting system for UCSD’s computer science building. The system is described in a paper presented last week in Kyoto, Japan at ACM SIGCOMM, one of the world’s premier networking conferences.


“If you have a wireless problem in our building, our system automatically analyzes the behavior of your connection – each wireless protocol, each wired network service and the many interactions between them. In the end, we can say ‘it’s because of this that your wireless is slow or has stopped working’ – and we can tell you immediately,” said Savage.

"Our system is the ultimate laboratory for testing new wireless gadgets and new approaches to building wireless systems. We just started looking at WiFi-based Voice-Over-IP (VOIP) phones," Savage said.
