It achieves this by using advanced modulation techniques (e.g., 256-QAM), wider channel bandwidths (up to 160 MHz), and multiple-input, multiple-output (MIMO) technology. These advancements support speeds exceeding 1 Gbps, making 802.11ac ideal for high-bandwidth applications like HD streaming and online gaming. ________________________________________ Why Other Options Are Incorrect? 1. Increased range: While 802.11ac may slightly improve range due to beamforming, this is not its primary enhancement. 2. Support for legacy devices: Both standards maintain compatibility, but this is not a specific improvement of 802.11ac. 3. Reduced interference: Not a direct focus of 802.11ac. 4. Improved battery efficiency: Benefits exist, but the main improvement is speed.
