• Spatial stream: unique simultaneous data stream

• Each spatial stream has a PHY rate of 150 Mb: 1x1 = 150 Mb, 2x2 = 300

Mb, 3x3 = 450 Mb

• Exam

(

at 5 GHz and 3 s

pp()p

streams (3x3) at 2.4 GHz. So, it has a 450 Mb PHY rate at 5 GHz and a

450 Mb PHY rate at 2.4 GHz for a total PHY rate of 900 Mb, thus the

name “N900”.

• Beamforming: control the output characteristics of each transmitter so that

the overall signal is optimized to reach a given receiver in a given

direction.
