An excellent research report that explains the different implementations of 5G technology by various carriers. If you have been confused about what is 'true 5G' versus why carriers are rolling out different 5G technologies, this research report will explain everything. What I found most interesting was that 5G is not some new standard that will obsolete previous 2G, 3G, and 4G technologies. In fact, 5G will need all these technologies to work effectively. 5G will build on the architecture of voice (2G); voice, video, and data (3G); and massive mobile data (4G)—and add massive bandwidth and density, as well as ultra-low latency.
