Security Mode Performance
Since this was the first time I had a fully Ralink-based draft 11n router and client in the lab, I tested throughput in all security modes, in 20 MHz bandwidth mode. Figures 12 and 13 show quite surprising results!
Figure 12: Security mode throughput comparison - uplink
Both plots show essentially no throughput loss in any security mode, WEP and WPA/TKIP included! This is in contrast to every other draft 11n product tested to date, which suffer throughput losses between 50 and 90% when using WEP or WPA/TKIP.
Let's hope this starts a trend that other draft 11n chip and product manufacturers will follow.
