| [* black] Used in conjunction with antenna system, the updated 802.11ac WiFi is designed to have multi-station WLAN throughput of at least 1 gigabit per second and a single link throughput of at least 500 megabits per second (500 Mbit/s). | |
| [* black] Compared to 802.11n the new 802.11ac has up to four times the RF bandwidth (up to 160MHz), twice the MIMO spatial streams (up to 8), and four times the modulation (up to 256 QAM). |
