much faster data download and upload speeds, wider coverage and more stable connections.
Imagine being able to download a high-definition film in a minute or so.
Most countries are unlikely to launch 5G services before 2020, but Qatar's Ooredoo says it has already launch a commercial service, while South Korea is aiming to launch next year, with its three largest network operators agreeing to kick off at the same time. China is also racing to launch services in 2019.
5G is much better at handling thousands of devices simultaneously, from mobiles to equipment sensors, video cameras to smart street lights.
Lack of signal and low data speeds in rural areas is a common complaint in the UK and many other countries. But 5G won't necessarily address this issue as it will operate on high-frequency bands - to start with at least - that have a lot of capacity but cover shorter distances. 5G will primarily be an urban service for densely populated areas.
Imagine swarms of drones co-operating to carry out search and rescue missions, fire assessments and traffic monitoring, all communicating wirelessly with each other and ground base stations over 5G networks.
Similarly, many think 5G will be crucial for autonomous vehicles to communicate with each other and read live map and traffic data. More prosaically, mobile gamers should notice less delay - or latency - when pressing a button on a controller and seeing the effect on screen. Mobile videos should be near instantaneous and glitch-free.

@Yaw: you mean, it will be very expensive? @Goodie: I think some telecom networks have upgraded to even 4G. Maybe, it is the "poor Nigerians" that is is struggling with 2G. Anything from 3G, 4G, and 5G is a luxury technology meant for the "RICH"
