Wi-Fi

Wi-Fi – a wireless networking technology that allows computers, smartphones, and other devices to communicate with each other and connect to the Internet without the use of physical wires. The term “Wi-Fi” is not an acronym, but a trademark for the IEEE 802.11x standard.

Scientific Basics of Wi-Fi

For Wi-Fi to work, radio waves are used. A device, usually a router, transmits these waves and Wi-Fi enabled devices receive them. These waves are then converted into data, enabling the wireless exchange of information.

Wi-Fi and Ethernet

Although both Wi-Fi and Ethernet serve the same basic purpose of connecting devices to the Internet, they do so in different ways.

Wi-Fi and Ethernet are both used to connect devices to the Internet.

Mobility. Wi-Fi allows freedom of movement, while Ethernet requires a physical connection. Mobility.

Speed. Traditionally, Ethernet provided faster speeds. However, the development of Wi-Fi technology has significantly narrowed this gap. Speed.

Security. Wired connections such as Ethernet are generally considered more secure than wireless connections, although Wi-Fi security has been enhanced by protocols such as WPA3.

Benefits of Wi-Fi

Convenience. Connect to the Internet from virtually anywhere within Wi-Fi range.

Multiple connections. Number of devices can simultaneously connect to the same Wi-Fi network. Multiple connections

Economy. Reduces the need for physical cabling and infrastructure. Fewer devices can simultaneously connect to the same Wi-Fi network.

Scalability. It is easy to expand the network by adding new access points.

Real Wi-Fi applications

Wi-Fi has enabled the transformation of various industries.

Home.From streaming movies to controlling smart devices, Wi-Fi is at the heart of the modern smart home.

Enterprises. In offices, Wi-Fi is used to ensure seamless connectivity, increasing collaboration and productivity.

Public places. Airports, cafes and parks offer Wi-Fi in public spaces, providing connectivity on the go. Public places.
