Experimental Demonstration of Time-Reversal MISO and MIMO Arrays with IEEE 802.11g Devices through a Ventilation Duct Channel

A practical demonstration of IEEE 802.11g transmissions using time-reversal antenna arrays in MISO and MIMO configurations is presented in this work. Throughput measurements indicate significant channel improvement through the use of time-reversal array coefficients and illustrate the viability of increased access point (AP) capacity and co-channel interference reduction in multi-user scenarios.
