Will a wireless router with multiple antennas work better?

(Summary description): Shenzhen Aerospace Communication Antenna Manufacturer Antenna Knowledge. A strange consumption habit exists in the daily consumption behavior of most consumers. When the price is almost the same, consumers tend to choose products with "large quantity". In addition, the phenomenon of following the trend is also very serious. Many facts have not been verified by themselves, and they have taken the initiative, "I will buy whichever product is bought by more people." The most representative group are the fans of "God Car Party" and "Heavy Doors". Similarly, most consumers who buy wireless routers have also fallen into the misunderstanding of "multiple wireless signals with antennas", and blindly followed the trend, and even became "the party with only the number of antennas". Is the factor affecting wireless signals really the number of antennas? Eliminate misunderstandings, the more antennas in wireless routing, the better? Why do wireless routers have multiple antennas? Just as aunts go shopping for groceries in the supermarket, "increase the quantity without increasing the price" is the sign that attracts their attention the most. "More", "big" and "cheap" deeply affect people's desire to buy. The same is true for consumers of wireless routers. The "god logic" that "built-in antennas must be inferior to external antennas" has always had a decisive impact on consumers' consumption concepts. In order to win the favor of consumers, some wireless router manufacturers even deliberately changed the internal antenna design to the external antenna design. This is like car manufacturers curry favor with Chinese consumers, adding a "butt" to the originally beautiful hatchback and turning it into a sedan as "horrible". Eliminate misunderstandings, the more antennas in wireless routing, the better? Are so many antennas really useful? When we open the wireless router product page of the e-commerce website, we can find that among the top ten wireless router products in terms of sales, wireless routers with three or more antennas occupy more than half of the positions. This phenomenon reflects that when consumers buy wireless routers, multi-antenna (more than two) wireless routers are very popular among consumers. Of course, multiple antennas have their advantages, but if there are more than three antennas in practical applications, it is generally meaningless in home scenarios. www.hangyu-sz.com Eliminate misunderstandings, the more antennas in wireless routing, the better? The home environment is complex, and the signal cannot be transmitted directly The use environment in the general family is more complicated. Both household appliances and walls block wireless signals, so that there is almost no direct signal from the transmitter to the receiver. The wireless signals reflected and transmitted by various items in the home form a phenomenon of "multipath transmission", and the data transmitted to the receiving end by different routes will be delayed, so we intuitively feel that the network has become "stuck". Eliminate misunderstandings, the more antennas in wireless routing, the better? MIMO technology "save the world" Then there is the "MIMO" technology that saves the world. Using MIMO transmission technology requires the support of multiple antennas. The router can divide the data into multiple parts and send them 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, which doubles the original work efficiency, increases the wireless speed and significantly improves the communication quality.
