What is the maximum theoretical bandwidth for the 802.11ac standard?

The maximum theoretical bandwidth for the 802.11ac standard is indeed in the range of 1.3 to 2.3 Gbps. This standard, which operates in the 5 GHz frequency band, introduced Multi-User Multiple Input Multiple Output (MU-MIMO) technology, which allows simultaneous communication with multiple devices and significantly improves network performance.

Additionally, 802.11ac supports wider channels (up to 160 MHz), higher order modulation (up to 256-QAM), and the ability to use multiple spatial streams, all of which collectively contribute to the increased data rates. The advancements in this standard represent a substantial upgrade over previous Wi-Fi technologies, leading to much higher bandwidth capabilities, especially in environments with multiple users and devices.

Other ranges provided do not accurately reflect the capabilities established by the 802.11ac standard. For instance, values much lower than the correct range describe older standards or different wireless protocols. The comprehensive capabilities of 802.11ac make it suitable for high-bandwidth applications, including video streaming and online gaming.
