The story is a bit complex, but it’s apparently a first: Nortel, Kyocera Wireless, and Runcom worked together to create the lab conditions to place a call using MIMO-equipped WiMax equipment. It’s all prototype gear, but it involved three different firms working together to produce the call, which included voice and streaming video. Nortel is heavily pushing MIMO-based WiMax; current WiMax standards don’t require MIMO, but there’s an expectation that it will be a significant part of wide-scale rollouts within a few years. MIMO buys you frequency reuse and greater range with relatively few penalties compared to simple omnidirectional antennas.
