Carriers around the world are preparing to move on from 4G LTE to 5G, the next era of mobile networking that promises ultra-fast data speeds and low latency between device and network. Consumers in the US can expect to start seeing 5G networks light up in 2019. All four major providers — Verizon, AT&T, T-Mobile, and Sprint — have promised to make 5G a reality in the new year. Even before those networks are switched on, smartphones from Samsung, LG, and other 5G-capable devices have already been announced.

The evolution and standardization of 5G has been a long process, but the technology could lead to major advancements in numerous areas like the smart home, media consumption, augmented reality, self-driving cars, telemedicine, and more.
