Wifi Antenna is the "signal messenger" of wireless network, and its core function is to realize the efficient Transmission of wireless signals, and to build a bridge between equipment and network by transmitting and receiving electromagnetic waves. When transmitting, it converts the electrical signals generated by the equipment into electromagnetic waves that propagate outward; When receiving, accurately capture the electromagnetic waves in the space and restore them to electrical signals to ensure the stable interaction of data. As an important device of network communication, the switch is responsible for the fast forwarding of data frames in the local area network. It can identify the MAC address of the connected device, establish the corresponding relationship between the port and the device through the learning and memory mechanism, and accurately transmit the data to the designated port according to the target address. With its high-speed data processing ability and rich port configuration, switches are widely used in enterprise office, data center, home network and other scenes, and are the basic equipment for building a stable and efficient network environment. From the perspective of usage scenarios and functional differences, WiFi antennas have multiple classifications: Computer WiFi antenna: born to meet the needs of computer portability and diversified use. The built-in antenna of notebook computer is compact in design, giving consideration to thin and light body and signal reception; The external antenna of USB interface can flexibly adjust its position, enhance the stability of network connection in weak signal environment, and make desktop computers enjoy wireless convenience easily. Router WiFi antenna: As the "signal intensifier" of the router, the Router Antenna expands the coverage by radiating omni-directionally or directionally. Omni-Directional Antenna provides signal coverage without dead angle for small and medium-sized space in the form of annular radiation; Directional antenna, with its concentrated signal beam, is suitable for point-to-point long-distance transmission and plays a key role in villas, large office places and other scenes. Outdoor WiFi antenna: It is often used in rural network coverage, wireless deployment of scenic spots and other scenarios to achieve large-area signal coverage. Indoor WiFi antenna: wall-mounted and ceiling-mounted, which can not only be hidden in the ceiling or wall, but also optimize the signal distribution according to the indoor space structure to ensure the network quality in every corner.
