Xiaomi Mi Router 4A R4AC
Xiaomi Mi Router 4A R4AC
Enjoy a wireless dual band speed of 1167Mbps for a faster and smoother online experience
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.
Smart Connect, once open this function in app, there’s no longer any confusion over which one to connect to
The Mi Router 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.
4 external antennas so that the signal can travel through walls better
4 external omnidirectional antennas, precision tested, and with a carefully designed internal structure and configuration Greatly improves transmission performance, even in complex environments.
Dual cooling fin heat sinks for better system stability
A specially treated metal substrate is combined with nanomaterials boasting exceptional thermal radiation features Offers both excellent heat absorption and heat dissipation capabilities to effectively lower the chip temperature and provide improved system stability.
Integrated signal amplifier, providing a good Wi-Fi signal and wide coverage
2.4GHz and 5GHz wireless chipset integrates PA and LNA.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.
In the age of the smart home, having more connected devices requires a stable network connection
Mi Router 4A has a large 64MB memory Ensures the stability of data transmission and stable connectivity of each access device.
