what is wlan network

 The most modern communication networks do not need cables. In fact, we are using more and more computers connected through wireless networks, which we colloquially call WiFi . Therefore, when we hear someone talk about the Wlan, it is normal that we wonder if it is the same thing. Let's see what Wlan is and if it is the same as a WiFi network or there are differences.  

What is Wlan by definition

Wlan stands for a local area network that connects computers without the need for cables. To do this, it uses radio frequency and sends a signal from one point to another, which has a receiver capable of interpreting the information. The frequencies can be different, so different networks can be configured in the same place.  

Is it the same as a WiFi network?

Although there are no drawbacks in referring to it as the same, there are differences between what is Wlan and WiFi . Actually, the Wlan is the network itself. A broad concept that can be transferred to various applications.

In the case of WiFi, it is a brand, responsible for regulating the current standard for equipment that handles wireless networks. At the moment the set of standards is encoded as 802.11. Devices that want to connect via the Wlan must adapt to these to function properly. In practice we can define both concepts as one. Therefore, referring to the Wlan network as WiFi is accepted. Especially since this is the only technology that uses Wlan networks for wireless communications . And also because the public is more familiar with the second term than with the first.  

A technology that improves day by day

A few years ago, when the Wlan appeared, it was considered an unsafe network . There were also problems with the speed of the network, which was well below what can be achieved via cable. However, both one element and the other have been updated. For example, in the case of security, data encryption protocols make it increasingly secure to use Wlan, even when sending sensitive information between networked computers. In other words, we are witnessing very rapid progress when it comes to protecting data and preventing it from being intercepted by sending it over radio waves. There are also advances in speed. Today transfer rates are achieved much faster than before. Although in this case it must be recognized thatcable technology has also accelerated use of wlan.  

Essential for the Internet of Things

Thanks to the development of wireless networks, connected devices are increasingly present . The idea is to turn homes into data entry and reception points, controlling all the devices in it and storing information. With this, you can later create more specific profiles with which to develop new products. For example, improvements for public purchases, without implying an invasion of privacy. As with other methods.
