1, not necessarily ap has fat ap, thin ap points. Fat ap does not need AC, thin ap does not need AC general wireless AP, its role has two: as the central point of the wireless LAN, for other computers equipped with wireless network cards through it to access the wireless LAN; By providing long distance wireless connections to a wired LAN, or long distance cable connections to a small wireless LAN, the purpose of extending the network range is achieved.
2, thin AP can also be used without AC control, only wifi names cannot be managed and cannot be the same. In terms of management, one AC can manage multiple aps, and one AP does not need to be configured separately, reducing the complexity of management.
3, Wireless AP and AC differences WLAN system is generally composed of AC (access controller) and AP (wireless access point), one is the controller, the other is the access point. Wireless AP: that is, "wireless access point", wireless access point is a wireless network access point, commonly known as "hot spot", it is a wireless switch for wireless networks, but also the core of wireless networks.
4, AP client), can be wirelessly connected to other aps to extend the coverage of the network. The concept of AC: it refers to the wireless access control server (AC), access controller (AC) wireless LAN access control equipment, which is responsible for aggregating data from different aps and accessing the Internet, and completing the configuration management of AP equipment, wireless user authentication, management, broadband access, security and other control functions.
