Super-G vs. Broadcom 11g - Streaming
Super-G vs. Broadcom 11g testing consisted of taking the previous scenarios and repeating them with the Atheros-based NETGEAR pair now set to Super-G mode.
The full implementation of Super-G has both static and dynamic modes. Among the differences are that static mode devices will only talk to other Super-G devices and channel bonding is always kicked in.
Dynamic mode in an AP lets 802.11b, 11g, and Super-G STAs all associate and transfer data and switches in channel bonding only when bandwidth demands require it.
Although NETGEAR's WG511T and WGT624 have been shipping with only static Super-G capability, NETGEAR recently posted BETA dynamic Super-G code. I tried both and found little difference when running the streaming and throughput scripts, so opted to use the more recent dynamic Super-G for my testing.
First up were the streaming vs. streaming tests.
Once again the throughput plot isn't very informative, so I've only shown it in Figure 18 for the 10 foot test. At 0.051%, Lost Data in the 11g stream is a little higher than the 0.041% shown in Figure 10, but, once again, doesn't represent significant performance degradation.
Figures 20 and 21 show Lost Data at 30 feet and 50 feet, coming in at 0.038% in both cases.
