What advantage does 802.11ac offer over previous wireless standards?

The advantage of 802.11ac over previous wireless standards lies in its ability to provide higher data rates and improved performance in dense environments. This is achieved through several key technical enhancements.

First, 802.11ac utilizes wider channel bandwidths, primarily 80 MHz and 160 MHz, compared to the 20 MHz and 40 MHz channels used in earlier standards like 802.11n. This wider bandwidth allows for more data to be transmitted simultaneously, significantly increasing the maximum throughput. The use of Multi-User Multiple Input Multiple Output (MU-MIMO) technology also allows multiple users to be served at the same time, which is particularly beneficial in environments with many devices, such as offices or public spaces.

Additionally, 802.11ac employs advanced modulation techniques, specifically 256-QAM (Quadrature Amplitude Modulation), which further enhances the amount of data that can be sent over the airwaves. This combination of increased bandwidth, multiple simultaneous transmissions, and advanced modulation results in much higher effective data rates and a better overall user experience, especially in scenarios where multiple clients are connected to the network.

Thus, the capability of 802.11ac to deliver higher data rates and better handle network traffic in dense environments makes it
