HomePlug announced that their next gen powerline specification, so called HomePlug AV2, will have MIMO (Multiple-Inputs Multiple-Outputs) which "offers significant increases in link throughput and range without requiring additional spectrum or transmit power."
HAN Fan likes the idea of better coverage for powerline based home networks, so HomePlug MIMO is a win.
HAN Fan thinks it might be a big win for HomePlug member and HomePlug AV contributor, Sigma Designs. They announced MIMO for their HomePlug AV chip in June 2010. Surely HomePlug AV2's MIMO is based on Sigma's?
