Wireless systems have been growing at an amazing pace, in terms of physical layer capability, application demands, and infrastructure and management cost. The latest boost in physical layer capability comes from MIMO -OFDM technologies. However, our 802.11n based channel measurements show the extent typical indoor MIMO -OFDM channels are often less than ideal, which has implications for building efficient wireless services over such channels. In this talk, I will describe several projects that aim to improve the efficiency of the physical layer transmissions, video delivery, and a large scale WLAN respectively, all motivated by the same observation of imperfect channel.
