The upgrade of WiFi 6 wireless routers is underway, and you can open the e-commerce website to see that the hot products are basically a water WiFi 6 route. And many new products, are built-in antennas, the shape can be more and more integrated into the home environment.
When buying a wireless router, many consumers keep their eyes on the antenna and think that the wireless signal is closely related to the wireless antenna. The more antennas the better, the longer the antenna, the better, the external antenna is better than the built-in... Hurry up, who spread these misinformation, but they are really worried about them.
In the face of compatriots with big "braids" high up, the wireless router with built-in antenna is going to cry. The focus of people's attention is always the most braids, in fact, we have a lot of built-in antennas! The appearance is not as high as ours, the design is not as beautiful as us, why is it still us who lose?
To correct people's misconceptions, we must first start with the reasons that affect the wireless signal strength. Why design multiple antennas? This is because of the use of MIMO launch technology, and it is precisely because of this technology that our wireless transmission is getting faster and faster.
Principles of MIMO technology
With MIMO transmission technology, multiple antennas are required to support, and the router can divide the data into multiple copies sent from different antennas and integrate them at the receiving end. Taking 2x2MIMO as an example, it is like two people working at the same time, doubling the original work efficiency, increasing the wireless speed and significantly improving the quality of communication. In this way, the intuitive feeling to the user is that the more antennas, the better the wireless signal and transmission. In fact, it is MIMO's "more in, more out" that makes multiple antennas play a powerful role.
Wireless transmission power affects signal strength
In addition to the transmission technology, the decisive factor for the quality of the wireless router signal is actually the transmission power of the wireless router. All countries have regulations on the transmission power of wireless routers, generally not exceeding 100mW, that is, 20dBm (2.4GHz band). So we can see that in fact, according to national standards, the signal strength of the transmitter is fixed. In summary, the signal strength has nothing to do with the external and built-in of the wireless antenna, and there is no more prejudice!
