1. Provides two frequency bands of 2.4 GHz and 5 GHz without interference, and the dual-band concurrent wireless connection rate can reach up to 1167 Mbps. The 2.4GHz band transmits farther, has better coverage, and better wall penetration performance. The 5GHz band uses 802.11ac technology with less interference and high speed. It is more smooth to watch high-definition video and play large online games.
2. Dual-frequency, a WiFi name, no longer tangled. The optimal frequency band is selected autonomously by the dual frequency terminal.
3. 4 external omnidirectional high-gain antennas, good signal through the wall.
4. Combine the specially treated metal substrate with the nano-material with high radiation characteristics, so that it has excellent soaking and heat dissipation capability, effectively reducing the chip temperature and improving system stability.
5. The PA and LNA are integrated inside the 2.4 GHz and 5 GHz wireless chips. The signal transmission distance is farther, the wall is better, and the coverage is wider.
6. In the era of smart home, more devices need to be stably connected. The Xiaomi router 4A uses 64MB of large memory and can stably connect 64 terminal devices.
7. When you set up Xiaomi smart home equipment to enter the network with Mijia APP, you do not need to manually enter the password, it is more convenient to access the network. When using the Xiaomi WiFi APP to modify the Wi-Fi password, the Xiaomi router 4A automatically synchronizes to the Xiaomi smart home device in the home, that is, after the router changes the password, there is no need to set the smart home device one by one.
8. IPv6 has a larger address space, making the Internet of Everything possible.
9. Intelligent error correction algorithm to improve weak signals and make transmission more stable and efficient.
10. Others pay for the Internet, exchange free bandwidth for revenue, and help you make money. The host and guest networks are isolated to ensure security.
11. Effectively protect your family health by setting the device networkable time and the range of URLs allowed to access. Combined with the intelligent speed limit function, you can limit the Internet access speed of each access device to avoid network congestion caused by individual devices.
12. Someone slams the net, notifies the phone in real time, and pulls the button black. Internet settings are quick and easy, and are easy for parents to use.
13. Xiaomi WiFi APP contains a variety of practical functions such as one-button speed measurement, Wi-Fi optimization, anti-mite network, etc., easy to manage the router and its access devices, remote control at any time and any place.
