With the advent of widespread Internet of Things (IoT) adoption in enterprise applications including manufacturing, agriculture, healthcare, and more—alongside an increasing dependence on smartphones and always-connected computers—the constraints of 4G LTE technology are prompting mobile network operators to embark on an accelerated rollout of 5G communications to keep pace with the network demands of today and the very near future.
This cheat sheet is an introduction to 5G mobile networks, as well as the smartphones, mobile hotspots, and IoT devices that run on them. The article will be updated periodically as new 5G technologies are standardized and as mobile network operators deploy 5G networks worldwide.

WHAT IS 5G?
5G refers to the fifth generation of mobile phone networks. Since the introduction of the first standardized mobile phone network in 1982, succeeding standards have been adopted and deployed approximately every nine years. GSM, the 2nd generation wireless network, was first deployed in 1992, while a variety of competing 3G standards began deployment in 2001. The 4G LTE wireless technology standard was deployed by service providers in 2010. Now, technology companies and mobile network operators are actively deploying 5G cellular networks around the world for new mobile devices. These 5G deployments accompany transitional LTE technologies such as LTE Advanced and LTE Advanced Pro, which are used by network operators to provide faster speeds on mobile devices.
