Recognition and classification of wireless network cards

Wireless network card: The wireless network card is a device for the terminal wireless network. It is a terminal that uses wireless signals for data transmission without wired connection. There are three types of wireless network cards: wireless network card receivers, wireless network card transmitters, and wireless network transmitters and receivers.

1. Wireless network card receiver: It is only responsible for receiving WIFI signals, connecting routers or wireless signals transmitted by other wireless devices for wireless connection.
2. Wireless network card transmitter: It is only responsible for transmitting WIFI signals. For example, the WIFI signals generated by the WIFI function of routing are transmitted through this hardware.
3. Wireless transmitter and receiver: It has the above two functions at the same time. This is the wireless network card of the notebook, which can transmit and receive WIFI signals at the same time.
