It's a laptop or a wireless network card to access the Internet, wifi.
How to build a wifi.
Generally, the basic equipment of building a wireless network is a wireless network card and an AP, so that the network resources can be shared in wireless mode with the existing wired architecture, and the cost and complexity of the installation are far lower than that of the traditional wired network. If it is only a peer-to-peer network of several computers, you can also do without AP, and only need to equip each computer with a wireless network card. AP is the abbreviation of AccessPoint, which is generally translated as "wireless access node", or "bridge".
It mainly acts as a bridge between wireless workstations and wired LANs in the first access control layer MAC. With APs, wireless workstations can be quickly and easily connected to the network, just like the hub of a typical wired network. Especially for the use of broadband, wifi is more advantageous, wired broadband network (ADSL, cell LAN, etc.) to the home, connect to an AP, and then install a wireless network card in the computer.
It is enough for an average family to have an AP, and even after the user's neighbor is authorized, there is no need to add ports, and the Internet can be accessed in a shared way.
Work long distances.
Don't look at the working distance of wireless wifi is not large, in the case of complete network construction, the real working distance can reach more than 100 meters, and it solves the problem of error correction and bit error of data when moving at high speed, and the switching between wifi equipment and equipment, equipment and base station and security authentication have been well solved.
The current application of wifi.
Since the WiFi band is a free band around the world without any telecommunications operating license, WLAN wireless devices provide a wireless air interface that can be used worldwide at an extremely low cost and with extremely high data bandwidth. Users can quickly browse the web in the WiFi coverage area, and answer and make calls anytime, anywhere**. Other WLAN-based broadband data applications, such as streaming** and online games, are worth looking forward to.
With the wifi function, we can make long-distance (including international calls), browse the web, send and receive emails, send and receive emails, and digital** delivery, etc., without worrying about slow speeds and high costs.
WiFi is becoming more and more widely used on handheld devices, and smartphones are one of them. Different from the Bluetooth technology applied to mobile phones earlier, WiFi has a larger coverage and higher transmission rate, so WiFi mobile phones have become a fashion trend in the mobile communication industry.
Nowadays, the coverage of wifi is becoming more and more extensive in China, and areas such as high-end hotels, luxury residential areas, airports and cafes have wifi interfaces. When we go to travel and work, we can use our handheld devices to surf the Internet in these places.

Many friends on the Internet are asking about China Mobile, Unicom, and Telecom, which mobile phone card has a stable and fast network speed? In fact, the three of them are still divided into different levels. Although China Mobile is very good, it is not the first, because in the early days, Telecom has monopolized the service advantage of broadband, from the post and telecommunications after the separation of all broadband resources to Telecom, even Unicom is later in the south to open up some situation before embarking on the road of broadband. >>>More
