Solution Overview
Service centers of government agencies in wireless city projects have the following characteristics:
- Administration service halls of government agencies are open areas with few concrete walls, and have obstacles such as bearing columns and working desks.
- The user density is not high.
- Office networks have certain per-user bandwidth requirements.
Generally, to meet WLAN requirements in such scenarios, indoor APs with built-in omnidirectional antennas are mount on ceiling or walls. The number of required APs is adjusted based on the field strength, user density, and bandwidth requirements in different areas.
Table 1 lists AP models used in service centers of government agencies.
