Xiaomi Mi 4A

details: AC1200 Dual Band Wireless Router
hardware type: Wireless Router
date added: 2021-02-27
updated: 2021-03-01
With 300Mbps over the 2.4GHz band and 867Mbps over the the crystal clear 5GHz band, the max wireless speed is up to 1167Mbps. The 2.4GHz band offers transmission over greater distances, with better coverage and better penetration through walls; The 5GHz band adopts 802.11ac technology. Less interference and higher speeds for a smoother experience watching HD videos and playing multiplayer online games.

The Mi 4A supports Smart Connect, offering 2.4GHz and 5GHz bands under one Wi-Fi name. No more confusion over which Wi-Fi network to connect to 2.4GHz offers better performance through walls, while 5GHz provides higher speeds. The optimal frequency band is automatically selected by a dual-band terminal.

The PA (power amplifier) effectively strengthens the signal transmission power, while the LNA (low noise amplifier) can improve the sensitivity of the signal receiver. Allows the signal to be transmitted over greater distances, with better penetration through walls, and wider coverage.

The 5GHz band supports the LDPC (low-density parity-check code) error correction algorithm to enhance anti-jamming capabilities during data transmission. This significantly enhances Wi-Fi signal coverage for improved efficiency in data transmission.

Effectively manage your family's time online by setting the amount of time a device may be online, and the websites that can be accessed. Combined with the intelligent speed limit function, the speed of each access device can be limited to avoid network congestion caused by individual devices.

When an unknown device uses the Wi-Fi signal without permission, the Mi WiFi app can send out a notification to inform the user that a new device has connected. If a suspicious device tries to join the network, depending on the security level, the device will be automatically blocked from connecting, or you will be prompted to block the device with one push of a button.
