portable device to make telephone calls using a radio link

A mobile phone is a portable device that lets you make telephone calls by sending signals through the air rather than through physical wires. It matters because it allows people to communicate with each other from almost anywhere, without needing to be connected to a fixed telephone line.

Encyclopedic overview

Two decades of evolution of mobile phones, from a 1992 Motorola DynaTAC 8000X to the 2014 iPhone 6 Plus Share of population with a mobile phone

A mobile phone or cell phone is a portable wireless telephone that allows users to make and receive calls over a radio frequency link while moving within a designated telephone service area, unlike fixed-location phones (landline phones). This radio frequency link connects to the switching systems of a mobile phone operator, providing access to the public switched telephone network (PSTN). Modern mobile telephony relies on a cellular network architecture, which is why mobile phones are often referred to as 'cell phones' in North America.
