To configure a local network, you need to understand the concepts of WLAN and WiFi, what is the difference and similarity between them. Thanks to wireless coverage, it was possible to open up Internet access to a large number of users. It is difficult to do this with a cable connection for technical reasons.The term WLAN stands for Wireless Local Area Network. This technology is designed to transmit data packets over radio signals, thus eliminating the need for a cable connection.
What is Wireless LAN
Previously, all LANs were cabled. They were used to connect desktop personal computers (within the same home or office) and exchange data between them.
Later, wireless networks were developed that use a radio channel for information transmission that meets the IEEE 802.11 standard. It is called WiFi, or Wireless Fidelity. Because of its ease of pronunciation, the abbreviation WiFi is used more often than WLAN to refer to this technology.
What do WLAN and Wi-Fi have in common?
Wireless Fidelity is a brand name used to refer to devices that connect to a wireless network. More often than not, the term WiFi is seen as synonymous with WLAN.
Companies from all over the world have formed an alliance that supports wireless technology and related devices. This association issues certificates for products provided that they comply with international compatibility standards. However, on the market you can find devices that fit this criterion, but at the same time are deprived of WiFi certificates and logos due to the high cost and complexity of the registration procedure.
Features of the wireless LAN in the phone
The Wi-Fi module is installed on any smartphones, but not all gadget owners use the capabilities of the wireless connection to the fullest. With this technology, Android or iOS devices can be connected to hotspots for free not only at home, but also in public places.
Thanks to WiFi technology, it became possible to save money on the mobile Internet. Operating systems for smartphones are strongly tied to the World Wide Web, as they need regular updates and data downloads. Transferring information over 3G and 4G mobile networks is more expensive because the network has restrictions on the amount of information downloaded.
Pros of a wireless LAN
The advantages of a wireless LAN are as follows:
The main advantage of WLAN is convenience for administrators and users. Simple and inexpensive wireless setup allows users to exchange information while in coverage.
The area covered by the signal can be expanded by installing additional routers (routers, APs) and antennas.
Physical barriers do not prevent radio wave propagation. Users get access to the Internet while on the move, on different floors or in other buildings.
WLAN technology eliminates a lot of wires in a room.
The data transfer speed can exceed 100 Mbps (depending on the router model). The radius of the coverage area can be 150 m excluding additional access points.
The connection speed is the same for all users.
WLAN devices from different manufacturers differ in price and performance.
