What makes 5G network better than 4G ? Will 5G replace 4G ?

What are the differences between 5G network and 4G network ? Will 5G replace 4G ? Will users be able to use both networks ?

The main advantage of 5G network is a higher speed. 5G is expected to be almost 100 times faster than 4G. It will depend on more factors like technology, coverage etc. 5G network will not replace 4G soon, because it is just being built. There are also not many devices with 5G support available yet.
