Description

technical field [0001] The invention relates to a local area network access device and its method, in particular to a code division multiple access (CDMA)-based mobile wireless local area network access device and its method. The invention belongs to the technical field of wireless network communication interfaces. Background technique [0002] Wireless Local Area Network (WLAN, Wireless Local Area Network), as an important part of the wireless communication network, has become a model of great success in the field of communication technology in recent years; especially the wireless local area network based on the IEEE 802.11 protocol suite has become a wireless The mainstream in the field of LAN has been widely used and has basically become synonymous with wireless LAN. At present, the application modes of wireless LAN can be divided into two categories: one is the wireless local area network built by enterprises or individuals, and the other is the operable public wireless...

AI Technical Summary

Problems solved by technology

Generally speaking, although WLAN can provide high-speed data services, WLAN lacks authentication and billing mechanisms for users, and the coverage of WLAN is small, and it is generally located in hotspot areas. In addition, it also has the following disadvantages: 1) The public wireless LAN architecture is complex and inconvenient to deploy; professionally trained personnel are required for architecture deployment, which is inconvenient for the promotion of public wireless LAN

2) The existing public wireless LAN still relies on the wireless expansion of the wired network. It is inevitable to lay network cables in the architecture, which will cause damage to the original building decoration, which also hinders the promotion in public hot spots

3) The existing public wireless local area network can only be used to provide wireless broadband data services to people in a static or quasi-stationary state

4) Lack of an effective charging model
