Something like that will have as fifth generation mobile standards are created. On the “official” side, there are the coming IMT-2020 standards. On the other hand, many “pre-5G” initiatives are in the works.
That means the pre-5G de facto standards will influence the “official” standards to some extent, even as understanding of what might emerge as IMT-2020 will shape pre-5G capabilities.
With the International Telecommunications Union targeting 2020, and major mobile companies, especially in East Asia, targeting pre-5G introductions possibly in 2017, the influences will work both ways.
It might be reasonable to suggest that the core specs largely will be reflected in the pre-5G introductions, or at least the ability to migrate seamlessly.
