MIMO technology changes how information for multiple users is mapped to signals so that performance for everyone is increased. It's been a hot topic for quite a while now and a lot of brainpower went into it. Performancewise MIMO, the major updatee in 802.11n, should produce a 10 fold increase in maximum thoroughput and 8 fold increase in average thoroughput over 802.11g while increasing the range. How is that not innovation? I supposed you don't think all the work that goes into silicon processing to make transistors 10nm smaller is innovation either?
