The article incorrectly states that the product offers 3 spatial streams. This is in fact incorrect. The Motorola product , along with ALL other vendor's products on the market today, supports only 2 spatial streams. Each spatial stream gives you 150Mbps of throughput, so having 2 streams gives you 300 Mbps, and 3 streams will give you 450 Mbps. There is no silicon vendors selling radio chipsets with 3 patial streams. Similarly, there is no client vendors supporting more than 2 spatial streams and 2x2 MIMO.
