It also shows improvements such as 4X efficiency for multi-devices, 2X WiFi speed, 7X battery life for client devices, and an 80% increase in WiFi range, with speeds up to 5400Mbps.

• OFDMA (Orthogonal Frequency Division Multiple Access): Improves network efficiency, especially in high-density environments, by allowing multiple devices to share a single channel simultaneously.
• MU-MIMO (Multi-User, Multiple-Input, Multiple-Output): Enables the router to communicate with multiple devices simultaneously, increasing overall network capacity and speed.
• 160 MHz Channels: Provides wider bandwidth for compatible devices, resulting in significantly faster wireless speeds.
• Target Wake Time (TWT): Reduces power consumption for connected devices by scheduling when they need to transmit or receive data.

6.2 Gaming Features

The TUF-AX5400 is optimized for gaming performance.

• Dedicated Gaming Port: Connect your gaming PC or console to the dedicated LAN port to automatically prioritize its network traffic, ensuring lower latency and stable connections during gameplay.
• Mobile Game Mode: Activate this mode via the ASUS Router app to prioritize mobile gaming traffic, reducing lag for smartphone and tablet games.
• Open NAT (Network Address Translation): Simplifies port forwarding for online gaming, allowing for easier setup of game servers and improved connectivity for multiplayer games. This feature can be configured in the router's web interface.

6.3 AiMesh Support

Create a seamless whole-home mesh WiFi system with AiMesh-compatible routers.
