5G has the potential to be 100 times faster than 4G, with a top theoretical speed around 20 Gbps and current, real-world speeds from 50 Mbps to 3 Gbps.
So, with 5G, you can download the entire movie in just 10 seconds, a task that takes about seven minutes on 4G. However, this speed also depends on the location and device.
Latency or 'lag time' is the time it takes a packet of information to travel between two points. 4G's lag times is about 50 ms (millisecond) while for 5G, it is 1 ms.
Low latency could have a huge impact in VR games, remote surgeries and translation services. Self-driving cars may use 5G to let a cloud-based AI make real-time navigational decisions.
With 5G, your normal internet will run at very high speed and on a single click, the largest file will be downloaded in a pinch.
4G can be used for high speed applications, mobile TV, wearable devices while 5G can be used for high resolution video streaming, remote control of vehicles, robots and medical procedures.
