Achieving a 450 Mbps data rate in 802.11n requires specific features:
Short Guard Interval (GI):Reduces the interval between symbols from 800 ns to 400 ns, increasing throughput.
40 MHz Channels:Doubles the channel width compared to 20 MHz, allowing more data to be transmitted.
3 Spatial Streams:Utilizes multiple antennas to transmit separate data streams simultaneously, significantly boosting data rates.
While frame aggregation and transmit beamforming enhance performance and reliability, they are not prerequisites for achieving the 450 Mbps MCS rate.
