Which technology allows mobile devices to access the Internet without wires?

Cellular technology is designed specifically for mobile devices to access the Internet without the need for physical wires. It operates by using radio waves to connect devices to a network of base stations, which are linked to the broader Internet infrastructure. This allows users to remain connected while on the move, providing flexibility and convenience for tasks such as browsing, streaming, and communicating.

Cellular networks consist of various generations, such as 4G and 5G, which offer different levels of speed and performance, catering to the growing demand for mobile data. This makes cellular the most appropriate choice for enabling wireless Internet access on mobile devices compared to the other options listed, which primarily involve wired connections.

Technologies such as DSL, cable, and fiber-optic rely on physical cables for connection, rendering them unsuitable for mobile device usage in a wireless context.
