Imo, the main issue is that most businesses don't know how valuable 5gn services are. For example, I had a job not so long ago where the computer systems were hideous and slow, partly internet wise but also due to a heap of data being physically stored on the computer itself. Adapting a cloud system for all the data would increase productivity dramatically through the day leading to increased profits for the company itself. As soon as more businesses can see the long term benefits instead of the short term cost, 5gn should take off client wise.
