Abstract
The Metricom Ricochet wide-area wireless network has recently
been deployed in the San Francisco Bay Area as a wireless Internet
access service. As with most commercial systems, little information is
available about the actual run-time performance of the system. This
paper describes the Ricochet system, and measures its performance in
the commercial system as well as in a locally deployed system. We present
measurements and analysis of TCP and UDP traffic throughput, UDP jitter, and interactive
latencies. Finally, we measure the interference of the Ricochet Metricom with the
AT&T WaveLAN device.
