What is going on with the wireless network card Do you not have to pay the network fee Where is ther

The so-called wireless network is a wireless local area network (WLAN) composed of radio waves as the medium of information transmission, which is very similar to the purpose of the wired network, the biggest difference is the difference in the transmission medium, the use of radio technology to replace the network cable, can be backed up with the wired network, but the speed is too slow.

The wireless network card is a device for terminal wireless network, and it is a wireless terminal device for Internet access through wireless connection network under the wireless coverage of wireless LAN. Specifically, the wireless network card is a device that enables your computer to use wireless Internet access, but with a wireless network card, you also need a wireless network that can be connected, if you have a wireless router or wireless AP coverage at home or location, you can connect to the wireless network through the wireless network card to connect to the Internet in a wireless way.

Use of wireless network cards.

A wireless network card alone cannot connect to a wireless network, and a wireless AP must also be used, which is equivalent to a hub for a wired network. The wireless network can only be connected if the wireless AP can be covered by the appropriate settings.

Wireless Internet access relies on wireless network cards, of course, supporting wireless routing (wireless cat).

The wireless network card is equivalent to the receiver, and the wireless router (wireless modem) is equivalent to the transmitter. In fact, it is still necessary to connect the wired Internet line to the wireless modem, and then convert the signal into a wireless signal and transmit it out, which is received by the wireless network card.

Generally, the wireless router can drag 2 4 wireless network cards, and the working distance is within 50 meters, and the communication quality is very poor. Strictly speaking, this wireless solution is just a wireless network, and the working environment must be next to the wired network.

The price of a set ranges from 300 to 800.

The other is pure wireless, which requires communication equipment, such as satellite receivers, or mobile phones that can access the Internet, etc., these things are connected to the computer through a special data line, and they receive signals from satellite or wireless network services, but the speed is not very good, and the communication cost is super expensive. And satellite receivers and mobile phones are also expensive, usually ranging from 3000 to 5000, the advantage is that even if you are in the wilderness, you can also access the Internet (of course, you must have a computer).

Both of these solutions can be used on laptops and desktops, of course, desktops are inconvenient to move in the first place, and wireless doesn't make much sense.

Expensive, generally by the minute.
