What is 5G ?
5G is the 5th generation mobile network. It will deliver new levels of performance and efficiency that will empower new user experiences and connect new industrie, it will achieve three main goals:
1) Speed (ultra-high speed radio access): 5G will provide download speeds of up to 20 Gbps. If you’re wondering “Why would anyone ever need that much speed?” It’s important to remember that bandwidth is shared by all the users on a cell tower. Today, if a few users are streaming a video at the airport or watching replays of a touchdown in a stadium, chances are that the download is choppy with lots of buffering, and the experience isn’t so great. With 5G, you could theoretically download a 40 gigabyte (GB) 4K Ultra-High-Definition (UHD) movie in less than a minute
2) Responsiveness (ultra-low latency): 5G networks will be used to control autonomous cars and high precision, mission-critical industrial devices in real-time. High reliability and availability at all times is a necessity for these use cases. For this to happen safely, end-to-end latency — the time it takes for data or commands to travel across the network — has to be extremely low. Latency in 5G networks will be five times faster than today’s networks — less than 1ms
3) Scale (massive connectivity): By 2020, Gartner conservatively forecasts that there will be more than 21 billion connected devices in the Internet of Things (IoT). Some estimates predict more than 50 billion connected IoT devices by 2020. These devices will have widely varying network requirements — from environmental sensors for agricultural applications installed in remote areas that might send a few bits of data every few days or weeks, to extremely high-precision, low-latency devices in nanobiotechnology, autonomous cars, and mission-critical industrial environments that rely on real-time communication for potentially lifesaving functions. 5G networks will need to handle the massive scale and challenging connectivity requirements for all these diverse devices, sensors, and applications
