What is the maximum speed of 802.11ac?

54Mb/sec
600Mbps
866MBps
1.3Gb/sec

The correct answer is: 1.3Gb/sec

The maximum speed of the 802.11ac wireless standard is indeed 1.3Gb/sec, which translates to 1300 Mbps. This standard, also known as Wi-Fi 5, was designed to significantly improve upon its predecessor, 802.11n, by utilizing wider channels (up to 160 MHz), multiple spatial streams (up to 8), and advanced techniques such as beamforming and multi-user MIMO. These enhancements allow for higher throughput and better overall performance in environments with multiple devices. The figure of 1.3Gb/sec reflects the capability of 802.11ac in optimal conditions, leveraging all available channels and spatial streams. Though theoretical, this maximum speed can be influenced by factors such as distance from the access point, interference, and the number of connected devices. Understanding these capabilities helps in appropriately deploying networks that can handle high data demands effectively.
