IEEE 802.11n-2009 is an amendment to the IEEE 802.11-2007 wireless networking standard to improve network throughput over previous standards, such as 802.11b and 802.11g, with a significant increase in the maximum raw OSI physical layer (PHY) data rate from 54 Mbit/s to a maximum of 600 Mbit/s with the use of four spatial streams at a channel width of 40 MHz.[1][2]

Since 2007, the Wi-Fi Alliance has been certifying interoperability of "draft-N" products based on what was draft 2.0 of IEEE 802.11n specification.[3] The Alliance has upgraded its suite of compatibility tests for some enhancements finalized after Draft 2.0. Furthermore, its has affirmed that all draft-n certified products remain compatible with the products conforming to the final standards.[4]


300M 其实就是802.11n  目前该草案基本结束，有的厂家在草案阶段就已经发布产品。
