Answer
We have released the WRAPxx-N models which support 2x2 MIMO. MIMO is most effective in extending range, overcoming moving obstacles like crowds of people or vehicles. MIMO does a number of things, including implementing space diversity, adding additional bandwidth, increasing forward error correction, adding out of band control, and more. The result is a more sensitive receiver, better reliability, and in some cases higher throughput.
MIMO can take some effort to configure for outdoor environments. You will need to determine the best supported modulation scheme (data rate) by looking at the registration of the links and optimizing the CCQ (compound value of SNR and bit error rates). Once optimized, you should then lock down the rates in point to point.
MIMO really works most effectively when in a point to point link with dual polarity antennas or in a point to multipoint configuration where all the station nodes are also running MIMO. If you mix MIMO and non-MIMO devices, you will see backward compatibility mode driving the overall network speed and performance down.

Vidovation demos portable wireless network video recorder. The microNVR is ideal for many applications combining on-site edge recording with live wireless relay such as in-vehicle video monitoring, light pole mounted video monitoring, solar powered remote video monitoring stations, camera back video recording and relay, and a pocket-carried video recorder.
We put the HauteSpot microNVR and Global Emergency Resources eWRAP to the test. Driving 700 miles from Meridian, Mississippi to Augusta, Georgia, we put a Mobotix megapixel camera attached to a microNVR and eWRAP in a moving van. The microNVR recorded at full frame rate and resolution all of the video from the camera. It also transcoded and pushed video out over the eWRAP using 3G EvDO wireless. The push architecture remained connected throughout the entire trip including through some relatively remote areas. See as short captured video of this test. 70 miles an hour, 700 miles, 10fps, VGA…
