Businesses even claim that using these multi-antenna wireless routers can increase network speeds.
Therefore, the number of antennas has become the focus of manufacturers' marketing. When we talk about multiple antennas, we first come to popularize MIMO technology.
[What is MIMO Technology]
A routing device that supports MIMO technology can divide the data into multiple parts and send it out from different antennas, and then integrate it at the receiving end, which effectively improves the efficiency and helps the signal coverage.
Taking the routing equipment of two antennas as an example, 2x2 MIMO is supported. Just as two people work at the same time, the original work efficiency is doubled, the efficiency of the WiFi signal received by the device is improved, and the communication quality is obviously improved.
Since most of the current smart router devices already support dual-band WiFi, they have 2.4 GHz and 5 GHz frequency bands. Therefore, the general 6-antenna routing device uses 3 antennas at 2.4 GHz and 3 GHz at 5 GHz. 3x3 MIMO effect.
Therefore, high-end router equipment will basically use six, eight, or even more antennas, in order to meet the 2.4G and 5G band WiFi signal quality and improve the wireless speed, and WiFi signal strength is determined by the transmission power intensity, and the number of antennas and No connection.
Major technical indicators affecting wireless networks
The effect of the number of antennas on the signal is not very obvious. The multi-antenna router signal is only about 10%~15% stronger than that of the single-antenna router. Generally, the insensitive people almost cannot feel the difference, and the two antennas and the four antennas Compared to the antenna router, the strength of the wireless signal is almost the same.
