Mobile computing allows transmission of data, voice, and video via wireless devices without a fixed connection. It uses technologies like tablets, laptops, phones, and PDAs to access network services anywhere. The history of mobile computing began in 1971 with the first wireless LAN experiment and continued with innovations like the first mobile phone call in 1973 and the first commercial cellular network in 1983. Mobile computing has key features of portability, social interactivity, context sensitivity, connectivity, and individualization, and it enables applications in areas like business, information, entertainment, and location services, bringing advantages of increased productivity and portability while also facing disadvantages like limited range, security issues, battery use, and signal interference.
