As we all know, the antenna is an an important part of the industrial wireless router. Is it true that the more antennas of the industrial wireless router, the better the signal of the router? In fact, the number of industrial wireless router antennas is not the main factor that determines the strength of the signal. Why, then what are the factors that determine the signal strength of industrial wireless routers% 3f
First of all, we all know that the earlier generation of industrial wireless routers will definitely not have more than one antenna. It can be seen from this that 802. 11n has obviously become a watershed, and since then, the antenna is no longer only a solitary one, so what is going on? Here we will mention a 11n protocol before it can get specific applications It is also a very important technology in the field of wireless communication - MIMO (Multiple-Input Multiple-Output, multiple input multiple output).
Some people say, why did I buy a new industrial wireless router with 3 antennas that supports the 802.11ac protocol, but the signal strength, coverage and even the speed did not go up? The antenna is not enough? In fact, in this case, we have to check the one you use Accept that the terminal does not support the AC protocol. Untuk contoh, if you are using an earlier iPhone 3, this phone can only support 11a/b/g and not even 11n, so even if you dismantle and add a few antennas to this product, it is useless, you only need to install an AC network card Or just change the terminal.
