802.11n is a wireless networking standard that uses multiple antennas to increase data rates. Sometimes referred to as MIMO (multiple input and multiple output), it is an amendment to the IEEE 802.11-2007 wireless-networking standard.
The purpose is to improve network throughput over the two previous standards—802.11a and 802.11g—with a significant increase in the maximum net data rate from 54Mbit/s to 600Mbit/s (slightly higher gross bit rate which is including error-correction codes and slightly lower maximum throughput) with the use of four spatial streams at a channel width of 40MHz. 802.11n standardized support for multiple-input multiple-output, frame aggregation, and security improvements, among other features. It can be used in the 2.4GHz or 5GHz frequency bands.
802.11ac is the newest generation of Wi-Fi signaling in popular use, 802.11ac utilizes dual-band wireless technology, supporting simultaneous connections on both the 2.4GHz and 5GHz Wi-Fi bands. 802.11ac offers backward compatibility to 802.11b/g/n and bandwidth rated up to 1300 Mbps in the 5GHz band plays up to 450Mbps on 2.4GHz.
