Problems solved by technology

[0006] However, MIMO technology has some significant disadvantages mainly due to its relatively high cost
Furthermore, like other technologies for WIMAX, WIFI, WPAN, and cellular communications, MIMO does not provide a system and method for dealing with dynamic changes in required bandwidth, nor does it provide an efficient way to make accurate directional transmission and reception become possible
