 Let's talk about what WLAN means first . WLAN is short for Wireless Local Area Network, also sometimes called Wireless LAN, and refers to a network of computers a few tens or hundreds of meters away, which uses high-frequency radio signals to transmit and receive data.

The WLAN network can also connect several computers to a central information system, a printer or a scanner. This provides mobility in networks (Internet) which also helps to avoid the use of heavy cables and difficult to interconnect.

Basically WLAN allows peer to peer and / or point-to-point data communications, such as LAN to LAN, WLAN to LAN or even WLAN to WLAN within a relatively small area.

Conventional LANs typically use twisted pair, coaxial cables, or in some cases optical fibers. WLAN gets rid of these physical connections and uses electromagnetic wave signals instead of transmitting and receiving data within the network. Potentially, the transmission is not as fast as that provided by a conventional LAN, but for most users, that slower transfer speed is not a limitation.

Now that we have seen what WLAN means, let's see what WI-FI is.

WI-FI is short for Wireless Fidelity. The term is currently a brand name used to brand products that belong to a category of WLAN devices. Devices or hardware marked with the WI-FI mark are based on the standards established by IEEE 802.11. In most cases, WI-FI is considered by most to be synonymous with the standard itself.

An association of companies around the world called "The WI-FI Alliance" endorses WLAN technology and the products involved with it. This alliance also certifies various equipment and devices if they conform to interoperability standards. It should be mentioned that there are numerous devices that actually conform to the standards but are not certified by this association and therefore do not use the WI-FI logo. The reason for this is the cost and hassle of the certification procedure.

A WI-FI (ready) device means that it is ready for use on a WLAN. Such devices range from desktop computers, laptops, notebooks, smartphones, and other small devices wlan connection.

 

 

Conclution

Although many use the terms Wireless LAN (WLAN) and Wi-Fi interchangeably, the reality is that there is a fundamental difference between Wi-Fi and WLAN: a Wi-Fi is actually a certain type of WLAN that uses the specifications of the wireless 802.11 protocol family

In summary, what is WLAN? It is a type of network equipment in a relatively small area that rules out the use of physical means of interconnection. What is WI-FI? It is a trademark name for brand devices that comply with the IEEE 802.11 standards. Devices in a WLAN essentially use WI-FI branded products. A WI-FI ready device simply means that it is ready for network operation within a WLAN.
