【摘要或目錄】：ABSTRACT
Tremendous consumer interest in multimedia
applications is fueling the need for successively
higher data rates in wireless networks.
Data rates in wireless wide area networks are
limited by the need to address wide coverage,
vehicular mobility, and the limitations of
licensed spectrum. Thus, data rates in WWANs
continue to lag advances in wireless local area
networks by orders of magnitude. There are
valuable lessons to be learned from the design
of WLANs that provide data rates in excess of
hundreds of megabits per second. Several technologies
will be instrumental in enabling future
high-performance WWANs, including multiple
transmit and receive antennas, OFDM, closed
loop transmission control, and low-latency MAC
operation. We describe a MIMO WLAN design
and prototype that exploits these attributes to
provide data rates in excess of 200 Mb/s above
the MAC
