Wifi Dual Band 4G PCB Antenna for Model

           What is the difference between the number of WIFI antennas?

   1. The difference between dual band Wifi Antenna for PC and single antenna is whether it is dual transmission and dual reception or single transmission and single reception. The LAN speed of the former is 300m, while that of the latter is generally 150m. When using a dual-antenna Wifi Antenna for Router , don't make the two Wfi Antenna outdoor parallel. Form a 135-degree angle, that is, one antenna is perpendicular to the desktop, and the other antenna forms a 45-degree angle with the desktop.
   2. Single-antenna routing, dual-antenna Wifi Antenna Indoor routing, three-wire routing and four-wire routing are different, but they have little impact on the actual use process, including signal coverage and signal strength. There is no point in having multiple antennas and high speed. Except for the rare single antenna, the remaining "multi-antennas" are only "media" or "tools" for realizing mimo technology. The difference lies in the different architectures used: common dual-antenna products mainly use 1t2r or 2t2r, while triple-antenna products use 2t3r or 3t3r.
   Theoretically, increasing the number of antennas will reduce the blind spots of signal coverage, but we have confirmed through a large number of evaluations that this difference can be completely ignored in ordinary home environments. In addition, just as the built-in antenna does not output external signals, the three antennas
   The situation that the coverage area of two antennas is not as good as that of two antennas is by no means an example. In the final analysis, product quality is also an important factor. As for signal strength and "wall penetration", it depends on the transmission power. The Ministry of Industry and Information Technology stipulates that it shall not be higher than 20dbm (i.e. 100mw). "The more antennas, the stronger the signal" will be defeated. The conclusion is that as long as the routing adopts good mimo technology, there is no need to care about the number of antennas.
   The number of wifi antennas does not determine the wifi signal.
