The smart?wireless controller is a network device used to centrally control a wireless AP, that is, a wireless network that constitutes an enterprise-level application. The smart wireless controller is the core of a wireless network and is responsible for managing all wireless APs in the wireless network. The management of the AP includes: delivery configuration, modification of related configuration parameters, radio intelligent management, and access security control. Wireless controllers Traditional wireless LANs are unable to meet the needs of advanced users who are relatively large in wireless networks and rely heavily on wireless services because of their limitations. These advanced enterprise users have introduced new feature requirements for a new generation of wireless networks.

An AC is a smart wireless controller that controls and manages a wireless AP. It can be used to view, configure, modify, and upgrade APs. This helps not only manage and maintain the entire network, but also improve the wireless network. Safety and reliability. Not all wireless AP networks require an AC, which is only needed in the thin AP+AC architecture. In other words, fat APs are not needed, and thin APs are needed.

In fact, in the early AP architecture, all wireless APs are connected through switches. Each AP must be independently configured and independent, responsible for communication, authentication, encryption, etc., which makes it difficult to achieve unified management and access. In and security policy settings. In a new wireless controller-based solution, the smart wireless controller is an excellent solution to these problems.

In AP+AC, instead of connecting the wireless AP directly to the AC, the AP is directly connected to the switch, and then the switch is connected to the AC. This makes the networking more flexible and the AP can be placed anywhere.

Here are some of the conventions of some ACs:

1, AC is used with thin AP, and many manufacturers of AC and AP are not interoperable, that is, their own AP with their own AC.

2, Want to know how many APs AC can take, very simple, just look at the number inside the model, such as Fengrunda wireless controller AC100, the number is 100, indicating that you can manage one hundred AP, basically the same for other manufacturers.

The smart wireless controller AC is more advanced than the AP and acts as a manager in the wireless network. The wireless controller AC also acts as a client to perform a series of functions (such as authentication, etc.) in the wired network. However, the wireless controller AC is not a WLAN device specified in the 802.11 protocol family, but is a supplement to the protocol in a specific application, and its price far exceeds that of an ordinary access point (AP) device. Therefore, in a small-scale wireless network using only a small number of APs, it is uneconomical to use an expensive wireless controller AC device.

The industrial-grade smart wireless controller terminal can directly replace the traditional wired transmitter to realize wireless analog quantity acquisition and transmission, and solves the problem that the wired scheme is complicated to construct and the equipment maintenance cost is high. Used in conjunction with sensors, transmitters, PLCs, DCS, frequency converters, smart meters, etc., successful applications include: wireless oil drilling rig rope tension wireless transmission equipment; pump room inverter wireless speed control; wireless boiler room equipment monitoring, steel plant monitoring equipment, grouting equipment wireless control remote control; wireless power transformer oil temperature wireless monitoring; wireless rubber plant vulcanization production process wireless monitoring system.
