Do WiFi antennas really work?

The router's Wifi antenna extends the signal range of the device by transmitting and receiving electromagnetic waves, while the PC's WiFi (2.4G/ 5.8G) antenna sends the received signal to the receiver, and then outputs it from the receiver. Without an antenna, the receiver's ability to receive signals will be poor, the internet speed will be slow, and the signal receiving range will be small. Therefore, routers, mobile phones, computers, projectors, set-top boxes, base stations, cameras and other products all need to install indoor 2.4G/5.8 G antennas. With the widespread popularity of the Internet, outdoor WiFi antennas have also ushered in development opportunities. In areas where the signal is relatively weak, outdoor 2G/3G/GSM/4G/5G Antenna can display their talents, significantly enhance the wireless signal and provide users with a better network experience.
