Wireless LAN Controller  What are they? + Basic Features ▷ 2020

Is not a no one’s secret that wireless networks they are becoming more and more a necessity for the human being, because thanks to them a great variety of technological functions and activities that are very important for the advancement of humanity.

In the case of Wireless LAN or also known as WLAN, It can be used the WLC or as it is also known Wireless LAN Controller, which is intended to be able centralize the control of Access Points or Access Points (APs). In this way they will not 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 is WLC, how does it work and what are its basic functionalities 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?

The WLC or Wireless LAN Controller has as main objective power centralize all control of access points, in this way it will be avoiding delegating a control for each of these points. Thus, 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 for Wireless Access Points “CAPWAP”.

All this will make LWAPS I sent 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 in a large WLAN network, and you won’t be creating multiple separate networks for them.

Furthermore, the main function of traditional wireless LAN drivers is to keep 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 teach you below:

These wireless LAN drivers are able to fulfill various types of functions and not only take care of the configuration of the access points.

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 they fulfill the WLC, and that many of the users believe that it is the only one that they can carry out. However, they also have the possibility to carry out some other important functions in the network system. In this case your objective is to centralize the control of the APs, and in that way do not delegate control to each of the APs. In this way the APs will no longer work 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 repeat each of operations on all APs on 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 allows sending and receiving alarms when any type of problem has been detected in the network. In order to ensure a homogeneous operation in the network, are included Software updates from AP operation, ensuring that everyone can have the same version.

Traffic aggregation and processing for wireless devices such as smartphones and tablets

It should be mentioned that this is one of the functions that are not performed all the time in the WLC, for 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 traffic, Either for encrypt it or separate it so that it is sent to different networks or to be filtering to prioritize it according to 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 radioelectric spectrum. All this causes a more efficient use of it in a specific local area.

Therefore, the mechanisms are grouped here so that each AP use a different portion of the electrical spectrum. In this case the mechanisms aimed at optimize traffic sharing between APs and wireless devices, they can detect interference and even geographically position devices using radio triangulation.

Non-WiFi features

Many of Controllers usually include functions that have nothing to do with what it is WiFi technology, as is the functionality of server for printers, the network hard disk or even the traditional fixed local network switch itself. Today WiFi networks have been strongly positioned in the market, and this is mainly due to the Cloud model what 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 as software at any point on the network that have IP connectivity with the Ap.
