AT-WNP300N - IEEE802.11b/g/n 1T2R Wireless Fast PCI adapter - User Manual
Appendix B: Radio Bands
Allied Telesis’s AT-WNP300N IEEE802.11b/g/n 1T2R Wireless Fast PCI 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.
