In modern times, offices have grown significantly in size to support the work of a large number of employees. In order to maintain smooth operations, proper communication procedures and data-sharing facilities need to be implemented.

This may seem impossible to achieve in a large office but thanks to WLAN, it is a very easy thing to implement. So, let’s see what WLAN controllers are and which protocol is used for the centralized management of WLAN.

What is a WLAN Controller?

A WLAN controller is a device that creates a network to connect devices with each other using radio transmissions rather than wires. The devices in your office connect to the network created by WLAN and then data is shared in packets using this network.

These devices also control which devices are connected to the network by monitoring the access points of WLAN’s network.

Does the Size of a WLAN Controller Matter?

WLAN controllers can be found in various sizes. Depending on the size of the company, the WLAN size will also be different. Larger companies need a lot of devices to connect to the same network. Larger-sized WLAN controllers are suited to connect a large number of devices on the same network while smaller ones are not able to do the same.

So, it is important that you check how many devices you want connected to the network and purchase the most suitable WLAN controller for your company.

What are Wireless Protocols and Which Protocol Is Used for Centralized Management of WLAN?

While the WLAN network is a great way to connect various devices across a network radius, it also opens up the possibility of unwanted devices getting connected and getting access to the data that is being sent over the network.

To ensure that the network of WLAN remains secure from such external invasions as well as, reliable and efficient in use, wireless protocols are used behind the scenes during the network’s active hours. The standard protocol that is used in WLAN networks is known as CAPWAP or Control and Provisioning of Wireless Access Points.

The CAPWAP protocol uses two key components to achieve its purpose of securing the network. These components are mentioned below:

  • Access Points: These provide connectivity to wireless devices on the network. They facilitate wireless communication and data relays between devices and the network.
  • Wireless LAN Controller: This component is responsible for managing and controlling the access points. It provides configuration, firmware updates, security policies, and other management functions to the connected devices.

Conclusion

Wireless connectivity is a major part of all types of companies big or small. A WLAN facilitates this by providing a network that allows for seamless and smooth communication and transfer of data across multiple devices.

With the support of a WLAN Protocol, you can keep data secured from outside threats ensuring that the data reaches the intended device.
