Dual-band Wi-Fi technology with a speed of 1167 Mbps enhances internet speed and performance for a smoother browsing experience.The dual-band feature at 2.4 GHz and 5 GHz enables interference avoidance, providing WiFi speeds of up to 1167 Mbit/s. The 2.4GHz band offers extended coverage and better performance through walls, while the 5 GHz band relies on 802.11ac technology for faster communications and reduced interference, enhancing the experience of high-definition video streaming and online gaming.

Merging the two bands into a single WiFi name reduces confusion.The Mi Router 4A combines the 2.4GHz and 5GHz bands into one seamless WiFi network, eliminating the need to worry about choosing a specific network. The 2.4GHz band offers better penetration through walls, while the 5GHz band provides higher speeds. This dual-band router automatically selects the most suitable frequency for optimal performance.Logging into the web admin interface is essential to enable this feature.

Four high-performance multi-directional external antennas have been strategically planted and rigorously tested to enhance transmission performance, even in challenging environments.

The built-in signal booster helps maintain a strong WiFi signal over a large area.Wi-Fi chips operating at 2.4 GHz and 5 GHz include integrated Power Amplifiers (PAs) and Low Noise Amplifiers (LNAs) to enhance signal transmission and receiver sensitivity. This improves signal range, wall penetration, and overall performance.

The extensive storage capacity of 128 megabytes ensures reliable connections for up to 128 devices.*Enable a reliable connection for all connected devices in the age of smart homes.

The intelligent error correction algorithm enhances weak signals to increase stability and efficiency.The 5 GHz frequency band uses LDPC codes for error correction, reducing interference and enhancing Wi-Fi signal coverage for more efficient data transmission.
