Measured performance of a wireless LAN

The performance of a high-speed commercial spread-spectrum wireless LAN that uses the CSMA/CA multiple-access strategy was studied. Using synthetic workloads, packet capture success rather than signal propagation characteristics was measured. Specifically throughput, packet loss rates, range, and patterns of errors within packets were measured. It is concluded that CSMA/CA is quite successful in allocating bandwidth under stress, but that packet capture rate degrades very quickly once the LAN´s effective range is exceeded. Hence, network maintainers should plan the layout of wireless networks at least as carefully as they plan wired networks
