Another method for providing cellular communication services is to deploy IEEE 802.11 standards-based high-speed wireless network, that is, so-called wireless local area network (WLAN) or Wi-Fi. When a number of access points are needed to cover an outdoor place, they are often called wireless mesh network. However, the deployment of wireless mesh network will impose strict requirements on the government when it expands the city network to the outside network and protects the security of the city network. Although the wireless medium has many unique advantages, what makes IT managers feel secure is that there is not much difference between the core WLAN security measure and the measure for constructing strict cable network. Therefore, through adopting suitable WLAN security measure, IT administrators can keep enterprise-level privacy.

Wafer network access service management system is a complete, practical and efficient tool for access management, network operation and maintenance, as well as business analysis, which provides comprehensive solution for network security, service billing, and business analysis, and such solution has been widely used in day-to-day network access management and related network operation and maintenance. Wafer wireless access control program needs no additional user management and control hardware, but only needs the bypass deployment software to provide access self-service functions for end users, and it can provide the following functions: IP address allocation strategy management, user management, access authentication management, statistics on users' network usage, as well as interconnection with other integrated accounting system.
