What’s the difference between 802.11n and 802.11ac?
Currently there are three commonly used wireless networking standards, which transmit data at very different maximum speeds.
Each is based on the designation for certifying network standards. The most common wireless networking standard, 802.11n,
can transmit information up to 450Mbps; 802.11a also supports up to 54Mbps, but in the 5GHz frequency; and 802.11ac draft
specification can connect at up to 1.3Gbps (3x3, 256 QAM). See the following chart for more detailed information.
