Last updated:October 2019

Editor's note

Similar to Oz's mysterious wizard, many basic explanations of fifth-generation wireless -- or 5G -- fail to see the technology behind the curtain. Like all wizards and technologies, 5G has its own complications and disadvantages. The newest generation of cellular network technology lacks consistent deployment guidelines, differs greatly from its predecessors and is one of several disruptive technologies that currently dominate the networking industry.

This guide delves into the nitty-gritty details of 5G, explained in a comprehensive way that provides insight into the technology behind the metaphorical curtain. Learn more about 5G's history, 5G challenges and how other technologies -- such as edge computing and Wi-Fi 6 -- could play with 5G.
