With the rapid proliferation of broadband wireless services, it is ofparamount importance to understand how fast data can be sent through a wirelesslocal area network (WLAN). Thanks to a large body of research following theseminal work of Bianchi, WLAN throughput under saturated traffic condition hasbeen well understood. By contrast, prior investigations on throughputperformance under unsaturated traffic condition was largely based onphenomenological observations, which lead to a common misconception that WLANcan support a traffic load as high as saturation throughput, if not higher,under non-saturation condition. In this paper, we show through rigorousanalysis that this misconception may result in unacceptable quality of service:mean packet delay and delay jitter may approach infinity even when the trafficload is far below the saturation throughput. Hence, saturation throughput isnot a sound measure of WLAN capacity under non-saturation condition. To bridgethe gap, we define safe-bounded-mean-delay (SBMD) throughput andsafe-bounded-delay-jitter (SBDJ) throughput that reflect the actual networkcapacity users can enjoy when they require finite mean delay and delay jitter,respectively.  Our earlier work proved that in a WLAN with multi-packet reception (MPR)capability, saturation throughput scales super-linearly with the MPR capabilityof the network. This paper extends the investigation to the non-saturation caseand shows that super-linear scaling also holds for SBMD and SBDJ throughputs.Our results here complete the demonstration of MPR as a powerfulcapacity-enhancement technique for WLAN under both saturation andnon-saturation conditions.
