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 indicates, a WLAN is a local type network whose computers do not need to be linked by cables to connect.
WLAN is a specific type of LAN : a computer network made up of units located in a small geographic space. While computers (computers) that are part of a LAN are connected to each other or to a wired router, in a WLAN the connection is made using radio frequency waves .
As they are wireless networks , WLANs often allow users to have wide mobility, since they do not depend on cables or physical elements to stay on the network. The absence of cables also contributes to maintaining order or 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 through a wireless access point (a device known as WAP for its acronym in English). In this way, the parent who uses the computer in the dining room can send a photograph to his son, who uses the computer in the bedroom. At the same time, the two of you can share files with whoever uses the laptop.
There are two main problems or weaknesses, let's put it like this, that a WLAN has:
-Security. It is considered that this is much more vulnerable than other networks, so it is necessary to take all possible measures in order to prevent anyone from accessing it. Hence, for example, what is chosen is encryption and the use of different keys and algorithms.
-Speed. In the same way, there is still much better for WLANs 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.
Faced with these setbacks or weaknesses of the WLAN, we can highlight its most notable advantages, some of which you have already been able to intuit to a certain 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 that, without a doubt, contributes both to making your work easier and to significantly improving your productivity wireless lan card.
-Although it may involve a higher cost at first in many cases, in the long run it is a much more profitable investment.
-The WLAN is installed really quickly and easily, so that you will be able to make use of it immediately.
-Precisely also the changes that have to be made are very easy to undertake.
