Is not a no secret that wireless networks they become more and more a necessity for the human being, because thanks to them they can carry out a wide variety of functions and technological activities that are very important for the advancement of humanity.
In the case of wireless LAN network or also known as , It can be used the WLC or as it is also known Wireless LAN Controllerwhich is intended to be able centralize control of Access Points or Access Points (APs). This way they won’t have to grant a separate control to each of them.
So that you can understand all this much better, here we are going to explain what WLC is, how it works and what its basic functionalities are in the network. To do this, follow in detail everything that we will teach you below.
What is a wireless network manager and what is this enterprise wireless network component for?
WLCs or Wireless LAN Controllers Its main objective is to be able centralize all access point control, this way it will be avoiding delegating a control for each of these points. Therefore, the AP will no longer work automatically but will become what is called a lightweight AP “LWAP”, For this, it will have the collaboration of the control and provisioning protocol to “CAPWAP” Wireless Access Points.
All this will make LWAPS send all the data towards the WLC. All this functionality will make it possible to do roaming, define wireless networks “WLANx – SSIDs” and authentication. For this, there is a design of WLC and LWAP combined into a large WLAN network, and you won’t be creating several separate networks for them.
Furthermore, the main function of traditional wireless LAN controllers is to maintain the configuration of wireless access points. But they can also have many other functionalities.
According to this, the WLCs are capable of performing many other functions such as the ones that we will show you below:
What are the main functions of a wireless LAN controller?
These wireless lan drivers They are capable of fulfilling several types of functions and not only taking care of access point settings.
That is why here we are going to show you what are the main functions of these LAN controllers:
Access point configuration
This is the main function that WLCsand that many of the users believe that it is the only one that can carry out. However, they also have the possibility of carrying out some other important functions in the network system. In this case your The objective is to centralize the control of the APsand in that way not delegating control to each of the APs. In this way, the APs will no longer function autonomously but will now become a lightweight LWAP AP.
Management and operation
These two tasks allow deploy and operate the wireless local network in a much easier way, so there will be no need to have to repeat each one of them. operations on all APs in the local network. Therefore, this allows configure, monitor and diagnose any type of problem that is generated in the network.
Another of its functions is that It allows sending and receiving alarms when any type of problem has been detected in the network. In order to secure a homogeneous operation in the networkare included Software updates of operation of the APsensuring that everyone can count on the same version.
Traffic aggregation and processing
It is worth mentioning that this is one of the functions that is not carried out all the time in the wlcfor this it will depend on the network architecture used. if all the traffic from wireless devices is routed through the controllerthen you can raise things with that trafficEither for encrypt it or separate it to be sent to different networks or to be filtered to prioritize it according to the established quality policies.
Local wireless features
In the case of the radio characteristics of wireless technology make advisable what is the use of coordination and protection mechanisms in the radio spectrum. All this causes a more efficient use of it in a certain local area.
Therefore, here are grouped the mechanisms so that each AP use a different portion of electrical spectrum. In this case the mechanisms aimed at Optimize traffic sharing between AP and wireless devicesthey can detect interference and even geographically position devices using radio triangulation.
Non-WiFi Features
many of Controllers they usually include functions that have nothing to do with what it is Wi-Fi technologyas is the functionality of server for printers, the network hard disk or even the traditional fixed local network switch itself. Today Wi-Fi networks have positioned themselves strongly in the market, and this is mainly due to the cloud model which is also known as cloud.
Thus the local WLC disappears and some of its functions are transferred to the cloud, thus being implemented centrally. In this way the traditional WLC has become a specific management element for WiFi, so it can be deployed in the form of software at any point in the network that have IP connectivity with the APs.
