What is WLAN?

1. What is WLAN?
A: WLAN is an acronym for Wireless Local Area Network. It refers to the application of wireless communication technology to interconnect computer devices to form a network system that can communicate with each other and share resources. The essence of the wireless LAN is that it no longer uses a communication cable to connect the computer to the network. Instead, it is connected wirelessly, so that the construction of the network and the mobility of the terminal are more flexible.

2. What is the speed of WLAN?
A: China Mobile WLAN adopts the 802.11b standard, which can provide 11Mbps speed, which is 200 times higher than fixed dial-up Internet access (56K). It can perform WWW browsing, send and receive emails, enjoy online movies, download files, and do business.

3, how to understand the unique limitation of WLAN?
A: During the commercial trial period, there is no restriction on uniqueness, that is, multiple users can access the same account and password at the same time. Therefore, users can share an account number and password with their loved ones and friends, but at the same time, they should pay attention to the storage of passwords to prevent them from being stolen by others.

4. What are the similarities and differences between WLAN and GPRS?
Both WLAN and GPRS are wireless Internet access methods provided by China Mobile, which together form the China Mobile’s “along with e-line” service, providing users with the “Internet-portable, world-minded” experience of wireless Internet access.

China Mobile currently provides GPRS network coverage in more than 240 cities. In indoor, outdoor, stationary or high-speed sports, it can achieve wireless Internet access through GPRS. The speed of Internet access is generally 20-30Kb; China Mobile operates in 31 provincial capital cities across the country. Airports, high-level hotels, convention centers, exhibition halls and other hot spots in cities, capitals, and municipalities directly under the Central Government, as well as in developed cities, have covered WLAN networks in more than 800 locations and will continue to expand. These network coverages are generally indoors, and the WLAN Internet access rate is 11M, which is much higher than GPRS, but it has limited coverage.

By providing users with WLAN services and GPRS services, China Mobile allows users to have suitable choices in different environments.

5. What terminal devices are required to use WLAN?
A: The average user needs to have a laptop/PDA and a wireless network card. If there is a built-in WLAN card in the notebook, you do not need to configure an additional network card. When the user chooses to use SIM authentication, a SIM card is also required.
