Abstract
A system, method and apparatus, provide for the utilization of the MIMO technique with single-antenna communication devices that maximize high-speed broadband communication. The apparatus includes a wireless communication interface (WCI) device configured to exchange wireless signals with a base station through a multiple input multiple output (MIMO) air interface and to exchange a corresponding set of wireless signals with an access terminal through a wideband air interface having a greater bandwidth than the bandwidth of the MIMO air interface. The system includes a plurality of WCI devices communicating with the base station and exchanging corresponding signals with the access terminal.
