Many sections of society, including different industries and cities, have evinced much interest in 5G networks, SO there is a pressing need to understand 5G capabilities and push 5G availability. 5G is about connecting everything in the future, which will weave 5G much more tightly into the fabric of our society and keep it running, in contrast to earlier generations of the technology, which focused on mobile broadband use case. The very high targets of 5G networks necessitate new technologies and new deployment models for implementation in live networks. It is expected that 5G com- bined with cloud and artificial intelligence can fundamentally impact society in terms of improving efficiency, productivity, and safety. 5G will first come with greatly improved mobile broadband capabilities operating together with LTE, and then move to provide wider selection of new use cases addressing new market segments with stand-alone 5G operation.
