how does a wireless network work

WLAN is an acronym of the English language which refers to Wireless Local Area Network , an expression that can be translated as Local Area Network Wireless . As the name points out, a WLAN is a local type network whose equipment does not need to be linked through cables to connect.
WLAN is a specific type of LAN : a computer network formed by units located in a geographic space of small dimensions. While the computers (computers) that are part of a LAN connect to each other or to a router with cables, in a WLAN the connection is made using radio frequency waves .

As they are wireless networks , WLANs usually allow users to have ample mobility, since they do not depend on cables or physical elements to remain on the network. The absence of cables also contributes to maintaining an order or an organization in the office or environment in question.

An example of WLAN is the wireless network that is installed in a home using WiFi technology . Suppose there is a computer in a bedroom, another computer in the dining room and a third laptop. All three computers have wireless network cards and are interconnected by a wireless access point (device known as WAP for its acronym in English). In this way, the parent who uses the dining room computer can send a picture to his son, who uses the bedroom computer. At the same time, the two can share files with whoever uses the laptop.
There are two main problems or weaknesses, let's say so, that it has a WLAN:
-Security. This is considered to be much more vulnerable than other networks, so it is necessary to take all possible measures to prevent anyone from accessing it. Hence, for example, what is encryption and the use of different keys and algorithms.
-Speed. In the same way, there is still much better WLAN in this regard. And it is considered that, at present, it has not yet managed to reach the speed that they do offer and have other types of local networks how does a wireless network work.

Faced with these setbacks or weak points of the WLAN, we can highlight its most notable advantages, some of which you have already been able to intuit to some extent:
-In companies it gives the possibility that any employee can obtain information from any part of it from your position and immediately. One circumstance is that, without a doubt, it contributes both to facilitating your work and to what it is to significantly improve your productivity.
-Although it may involve a higher cost at first in many cases, in the long run it is a much more profitable investment.
-WLAN is installed really quickly and easily, so immediately it will be able to use it.
