1. is installed in the supporting wireless network card Cato, and then Cato is connected to the computer to install the Cato driver. After successful installation, you can log on to the network with the account and password of the wireless network card.

2, installed on the corresponding telecom smart phone. Open the settings, enjoy the mobile network * * *-portable WLAN hotspot, open this hotspot, and then set the password. Let mobile devices connect to this hotspot to surf the Internet.

The differences between wireless network cards and wireless network cards and wifi are as follows:

1, with different meanings:

Wireless network card is actually a kind of terminal wireless network equipment, which needs to surf the Internet through wireless connection network under the wireless coverage of wireless local area network. Wi-Fi is the trademark of the manufacturer of Wi-Fi alliance as a product brand certification, and it is a wireless LAN technology created in the IEEE 802. 1 1 standard. A wireless network card refers to a wireless WAN card connected to a wireless WAN.

2. Different functions:

The function and function of wireless network card is equivalent to cable modem, which is also commonly known as "cat". It can use USIM or SIM card to connect to the Internet anywhere with wireless phone signal coverage. The wireless network card functions like a wireless modem.

The function of wireless network wifi is actually to convert wired network signals into wireless signals, just as it was introduced at the beginning, using wireless routers to receive related computers, mobile phones, tablets and so on that support its technology. If the mobile phone has Wi-Fi function, it can surf the Internet without using the mobile Unicom network when there is Wi-Fi wireless signal, thus saving the traffic fee.

The function of a wireless network is to access the wireless terminal equipment of the Internet through a wireless connection network under the wireless coverage of a wireless local area network. Generally speaking, a wireless network card is a device that can surf the Internet without connecting a network cable.

? The dispute between WAPI and WIFI

WAPI (wireless local area network authentication and

Privacy Infrastructure) wireless LAN authentication and security infrastructure is a security protocol and a mandatory standard for wireless LAN security in China.

WAPI standard released in 2003 (full name is WLAN authentication and security infrastructure), as a WLAN security technical standard with independent intellectual property rights independently developed by China, is two different protocols from Wi-Fi, and the biggest difference is the difference in security encryption technology. For the sake of Internet security, China has always strongly suggested WAPI as an independent international standard.

China originally intended to enforce the WAPI standard from June 1 2004, but it was resisted by American companies such as Intel and even the American government. Until June, 2009, WAPI was unanimously agreed by the United States, Britain, France and other countries 10 for the first time, and it was upgraded to an international standard in the form of an independent text.

What happened is as follows:

At the end of 2003, the General Administration of Quality Supervision, Inspection and Quarantine and the National Standardization Administration announced that the WAPI standard would be enforced from June 1 2004. This move was immediately resisted by American companies such as Intel and even the American government, and threatened to stop wireless business in China, claiming to join hands with WAPI.

Western companies prefer to adopt their own standards rather than standards.

On April 22, 2004, after negotiations between China and the United States, Wu Yi, then Vice Premier of the State Council, China, said that China agreed to the request of the United States and would not enforce the WAPI standard. In July, China formally submitted the WAPI proposal to the International Organization for Standards. However, the WAPI standard met with unprecedented resistance in China, and it was forced to run aground as an international standard.

Who would have thought that this wait was five years, and it was not until June 2009 that things took a major turn for the better. The WAPI Industry Alliance of China publicly confirmed that at the ISO/IEC JTC1SC6 meeting in 20 10, WAPI won the unanimous consent of the United States, Britain, France and other countries for the first time, and will be promoted as an international standard in the form of an independent text.

Some experts regard this incident as

For the first time, the United States began to fulfill the landmark event of "promoting WAPI to become an international standard".

According to the latest policy of 20 10 of the Ministry of Industry and Information Technology, any mobile phone with WAPI function can access the network and obtain a network access license. The principle is that this kind of mobile phone can use WAPI access when there is a WAPI network, and can access the wireless network through Wi-Fi when the WAPI cannot be searched, but the pure Wi-Fi mobile phone still cannot be listed.
