Summary of Test Results
We've covered a lot of ground, so I've pulled together the table below to bring it all together.
|Summary of True MIMO Test Results|
|The Pitch||The Result||Comment|
|Speed vs. Range compared to standard 11g||Superior to any other technology that I've tested to date.|
|Interoperability with Belkin Pre-N||No problems. Belkin and Linksys both use same Airgo reference designs|
|Performance with mixed True MIMO / 11g STAs||11g STAs suffer significantly reduced throughput for Broadcom-based STA tested.|
|Performance with mixed True MIMO / Super-G STAs||Super-G STAs throughput significantly reduced for uplink.|
Better throughput for downlink, but still less than True MIMO STAs
|Performance with mixed True MIMO / 11b STAs||Similar to Super-G case.|
Significantly reduced 11b throughput for uplink, better for downlink
|Improved performance when client used with 11g APs||Throughput approximately doubles in some test locations.|
|Improved performance when AP used with 11g STAs||Throughput approximately doubles in some test locations.|
|Key: = Excellent = Mixed results = Poor|
The thing I find curious about these results is that it says that True MIMO works best in a pure True MIMO WLAN (as one would expect), and next best in unmixed, but non-True MIMO WLANs. The mixed WLAN results are, well, mixed, which seems to force buyers into an interesting position if they are buying True MIMO gear to upgrade an existing WLAN.
