With the spread of Wi-Fi (Wireless Local Area Network), the Internet became mobile from the 2000s onward. Wi-Fi enables wireless access to the Internet in homes, businesses, and public buildings.

The launch of the first iPhone in 2007 further revolutionized the Internet: Now users could be online anytime, anywhere.

Modern smartphones offer fast Internet access via LTE or 5G, high-performance cameras, and unlimited access to information and communication. This fundamentally changed the way people work, learn, and spend their leisure time.
