How was the mobile wireless communication technology evolved?

Mobile wireless communication system has gone through several evolution stages in the past few decades after the introduction of the first generation mobile network in early 1980s . Due to huge demand for more connections worldwide, mobile communication standards advanced rapidly to support more users.

The very first generation of commercial cellular network was introduced in the late 70’s with fully implemented standards being established throughout the 80’s . The radio signals used by 1G are analogue, meaning the voice of a call is modulated to a higher frequency rather than being encoded to digital signals.

In few past decades , the mobile wireless evolution progressed from Zero Generation (0G) to First Generation (1G), Second Generation (2G), Third Generation (3G), and now Fourth Generation (4G) systems are being deployed with the aim Quality of Service (QoS), efficiency and performance.

Modification in mobile features is responsible for the evolution of mobile communication generation such as 1G, 2G, 3G, 4G, and 5G technologies which are further integrated using GSM, GPRS technologies.
