Wireless dual-band 1167 Mbps for faster and smoother internet connections

The dual concurrent bands, 2.4 GHz and 5 GHz do not create interference and offer wireless connection speeds of up to 1167 Mbps. The 2.4-GHz band transmits over greater distances for better coverage and better performance through walls; the 5-GHz band uses 802.11ac technology to reduce interference and boost connection speeds, for a smoother experience when watching HD videos and playing online games.

Dual-band integration with one Wi-Fi name eliminates confusion

The Mi Router 4A supports dual-band integration, combining the 2.4-GHz and 5-GHz bands under one Wi-Fi name. No more having to worry about which Wi-Fi to connect to 2.4-GHz band offers better transmission through walls, while the 5-GHz band delivers higher speeds. The dual-band device automatically selects the optimal frequency.

An integrated signal amplifier ensures a good Wi-Fi signal over a wide coverage area

The 2.4-GHz and 5-GHz wireless chips each feature an integrated power amplifier (PA) and low noise amplifier (LNA). The PA effectively enhances signal transmission power, while the LNA improves signal reception sensitivity. This allows the signal to be transmitted over greater distances, better pass through walls, and cover a wider area.

Large 128-MB memory supports stable connections for up to 128 devices
Smart Home Era Ensure a stable connection for each and every connected device

The smart error correction algorithm improves weak signals for greater stability and efficiency.

The 5-GHz frequency band supports low-density parity code (LDPC) code to correct errors. This reduces interference during data transmission and significantly increases Wi-Fi signal coverage for more efficient data transmission.

Powerful cooling to guarantee safe operation at all times

The chassis employs broad-surface aluminum-magnesium alloy heat sinks and high-conductivity thermal paste and large vents on the bottom to effectively improve the cooling efficiency of the whole unit. The rear panel has added cooling vents to facilitate airflow. This conducts heat away from the internal components to the outside, ensuring the long-term reliable operation of the device.

The eco-friendly casing protects the environment

The outer casing and packaging of the Mi Router 4A Gigabit Edition are made of recyclable and environmentally friendly materials, reducing damage to the environment, so that we can protect our precious planet.

Rigorous testing in pursuit of excellence in quality

Power supply stability test:≥ 220,000 times(Four scenarios and 20 prototypes’ cumulative times powered on and off)
Testing in a challenging environment: ≥ 1000 hours(Six scenarios and four prototypes’ cumulative tests)
Hardware structural reliability testing:≥6 times(Drop test: marble floor, height 1 meter)
