WLAN & LAN: What Is The Difference

Difference Between WLAN and LAN, there is a fundamental difference that you probably already know: WLAN works wirelessly, while LAN is based on cable data transmission. Including this basic feature, we talk about what is behind the two terms.
How does the WLAN work?
WLAN stands for wireless local area network. A wireless network where communication between computers is done through the radio. A problem related to the use of WLAN is low security , since the cryptographic standard is not enough at present. If you choose a WLAN and want to be sure to surf a secure network, you need additional security measures. The WLAN is composed of network nodes, each of which forms a radio cell. Communication between network nodes is possible as long as the radio cells overlap.
The range of a radio cell is about 300 meters outdoors. Inside buildings, although electromagnetic radiation is capable of penetrating windows and walls, it does not exceed 30 meters. Repeaters can be used to increase coverage. The data transfer rate depends on the standard used and varies between 2 Mb / s and 600 Mb / s. However, radio interference makes this rate difficult to achieve. Reality shows much lower data ranging between 0.9 and 74 Mb / s.
How does the LAN work?
LAN is the acronym for Local Area Network and, as the English word suggests, it is a network computer system in a small space, such as a four-wall office. The LAN is characterized by a high data rate and a low error rate. Another advantage is the lower risk of hacker attacks compared to WLAN.
