Fibre-optic full-gigabit router delivers faster connection speeds

Fibre-optic full-gigabit for high-speed broadband over 100 Mbps
The Mi Router 4A Gigabit Edition features one gigabit WAN port and 2 gigabit LAN ports, easily achieving network speeds of 100 Mbps and above. Compared with 100-megabit ports, this allows you better utilise every megabit of bandwidth.

Dual-core CPU for faster connection speeds
Features dual-core quad-threaded processors with a single-core clock speed of up to 880 MHz for powerful performance that easily supports gigabit network ports and gigabit dual-bandWi-Fi data transmission for a smoother online experience.

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.

The 4 precision-tested external omni-directional high-gain antennas have been carefully designed and arranged to maximize transmission performance, even in more complex environments.

Integrated signal amplifier ensures 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 aluminium-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 air flow. This conducts heat away from the internal components to the outside, ensuring the long-term reliable operation of the device.

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.
