You've probably already heard about 5G, the new cellular technology that's poised to bring massive change to both mobile and fixed wireless data networks. What you may be wondering is how 5G differs from 4G, the current cellular network standard, and what benefits the new technology will bring both enterprises and individual users. To bring you up to speed on 5G's structure and capabilities, and how it improves on 4G technology, here's a quick update.

What is 5G?

As the latest step forward in cellular network evolution, 5G will see untold thousands of small antennas deployed onto cell towers, utility poles, lampposts, buildings and other public and private structures. The technology, which is designed to supplement rather than replace current 4G networks, promises to accelerate cellular data transfer speeds from 100 Mbps to 10 Gbps and beyond, a massive boost that will make next-generation wireless competitive with even the fastest fiber-optic wired networks.

Overall, 5G should significantly improve the bandwidth, capacity and reliability of cellular broadband far more than previous generational shifts. Major carriers are already formulating their 5G strategies. In the US, the top four carriers—AT&T, Sprint, T-Mobile and Verizon—will begin rolling out 5G networks in 2019 and 2020.

On the mobile phone front, Verizon and Samsung have partnered to make a 5G smartphone they plan to begin marketing in the first half of 2019. Apple, however, won't roll out its 5G phone until 2020. Inside homes and offices, 5G technology is expected to provide serious competition to cable- and telephone-based Internet service providers (ISP).
