Hi,

What is the difference between multiple input multiple output (MIMO)
system and
Adaptive antenna system (AAS) ?

I find the WiMAX uses MIMO and AAS . But, the definition appears to be
the same.

Both the systems are exploiting more than one antenna to improve the
coverage and the system capacity.

I wonder why different naming convention for the same system !!
Is there any significant features/differences in MIMO and AAS ?

Thx in advans,
