What is the theoretical bandwidth range of the 802.11n standard?

The 802.11n standard, also known as Wi-Fi 4, is designed to deliver significantly higher data rates than its predecessors. This standard employs multiple input multiple output (MIMO) technology and can use multiple channels to enhance bandwidth. The theoretical maximum data rate of 802.11n can reach up to 600 Mbps under optimal conditions, achieved through the use of four spatial streams and a channel bandwidth of 40 MHz.

When considering real-world scenarios, various factors can influence the actual achieved throughput, such as range, interference, and device capabilities. However, the theoretical maximum range of 72 to 600 Mbps effectively captures the capability of this standard, highlighting its improvements over earlier specifications. Other options are based on older standards that do not reflect the enhanced performance provided by 802.11n.
