AT-WNU300N - IEEE802.11b/g/n 2T2R Wireless Fast USB adapter - Installation Guide

Appendix B: Radio Bands

Allied Telesis’s AT-WNU300N IEEE802.11b/g/n 2T2R Wireless Fast USB

adapter is capable of operating in the 2.4GHz (IEEE 802.11b/g/n).

IEEE 802.11 n standard provides a major improvement in the speed at which

data can be transferred over a wireless network. The amount of data being

passed over most networks is increasing with many more large files, including

photos, video clips (and videos), etc. being transferred.

IEEE 802.11 n standard uses Multiple Input Multiple Output (MIMO)

exploiting multipath propagation; that increases the data rate by using a

technique known as spatial division multiplexing. The data is split into a

number of spatial streams and these are transmitted through separate

antennas to corresponding antennas at the receiver. Increasing the spatial

streams you get a greater utilization of the available bandwidth.
