The Evolution of Mobile Communications, from 1G to 5G[br]When we describe mobile communications, we refer to the overall technology, speed, frequency and system in numeric generations such as 3G, 4G or 5G. Each generation have unique technologies that define them. This blog explores and explains the differences throughout the evolution of mobile communications and what we can expect from the future generations of these technologies.[br][br]1G[br][br]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.[br]Analogue signals degrade over time and space meaning that voice data can very often lack quality within a call. In comparison, digital is a representation of analogue stored as signals, meaning larger amounts of data can be carried more effectively.[br] |
