14. … for TS2008 Slide 14 Spatial Multiplexing MIMO MIMO = Multiple Input Multiple Output A high rate signal is split into multiple lower rate streams and each stream is transmitted from a different transmit antenna in the same frequency channel. Streams merged into one signal TX Lower rate streams High rate signal RX

15. … for TS2008 Slide 15 Benefits of MIMO-OFDM MIMO achieves significant increases in capacity, range and reliability without additional bandwidth or transmit power Increased range and reliability: The Ethernet data stream is split into two lower rate chains. These chains can be transmitted in lower rates, achieving longer ranges and higher reliability Increased capacity and improved spectral efficiency Each radio (chain) carries the full OFDM channel capacity Both radios use the same 20MHz channel Thus doubled capacity per the same channel bandwidth Improved availability The streams arrive at the receivers in different quality. MIMO chooses the best stream available Paths in poor quality are thus eliminated and availability increased
