4.1.4 SPATIAL STEAMS AND SPEEDS

The Table Below (source WiFi Alliance) shows spatial streams and expected link data rates for each type of

802.11 wireless technology.

Note: If you view the Status window of your Wireless Client on your PC, upon initial connection to a wireless

network, you will see receive capabilities, then you will settle on transmit capabilities (1 or more transmit spatial

streams), appearing as link data rate from PC to wireless access point. Some 802.11n wireless adapters support 2

receive spatial streams, and only 1 transmit spatial stream, so max transmit data rate for 20MHz wide channel =

72.2Mbps link data rate with Short Guard Interval (SGI).

So, in the example case with a Wireless adapter that supports 2 receives and 1 transmit, if you view the Windows

Wireless Client application, you will first see 144.4Mbps (2 receive spatial streams), then 72.2Mbps (1 transmit

spatial stream). See below the table below, last row 20Mbps channel width with SGI enabled, 1 stream vs 2

streams.
