MIMO technology promises higher data rate, higher quality of service and better reliability by exploiting antenna array at both the sides (transmitter and receiver) are mixed such that they either generate multiple parallel, spatial bit-pipes and/or add diversity to decrease the bit-error rate.
The fundamental gain in MIMO is increased data rate. MIMO is better and the only stratergy for achieving both the higher data rate and better quality of service. By spreading the transmitted signal over multiple paths, the MIMO technology increases the chances of signal reception at the receiver. It also increases the range of the operation.
In the fig6 MIMO covers all the three base regions of convential cellular telephony. The transmitter can adjust power and phase of the signal fed to antennae, which allows the best transmission quality.
