Craig Mathias of the Farpoint Group runs down the state of MIMO and its future: MIMO’s current technology appears in products from four vendors, two of which are following a multiple antenna strategy that the other two (and their chip supplier Airgo) say flatly isn’t MIMO. Airgo, Linksys, and Belkin would argue that spatial multiplexing, or sending data over the same frequencies through different paths is MIMO while the others use beamforming and phase array techniques.
Mathias recommends MIMO unhesitatingly after performing tests with Belkin’s Pre-N gear and a variety of 802.11g adapters and gateways. He points out rightly that for distance and throughput, MIMO beats cheaper 802.11g devices because of the complexity—and might be cheaper depending on how many 802.11g devices you’d have to put together to reach the same results.
