The term evolution/evolved (E) is everywhere in communications, and simply put I don't understand why. The answer I am looking for is one that will help me know what meaning I should associate with the term evolution, why was it chosen? Does it describe a physical property? When I see "E" or "evolved/evolution" I should know it means.
Currently my understanding has been shaped and formed from this resource: http://www.3gpp.org/technologies/keywords-acronyms/100-the-evolved-packet-core
This has shaped my understanding to be: evolution/evolved is its literal definition, one where something has grown or changed over time. In the context of communications it represents that the technology is no longer based on CS (circuit switching) and packet switching (PS) but now based on IP (internet protocol)
My goal is to gain further insights into the core workings of mobile/IoT networks and I am looking for a more detailed definition of the term "evolution/evolved" and why it is used in a lot of acronyms and what does it mean or what should I know when I see it.
