In reply to peter mckenzie.

Agree Peter, many details and steps are being worked out and ratified before the commercial roll-out of 5G. The 3G and 4G modeled Cisco VNI speeds are based on actual speeds and not theoretical speeds that are being realized in the testing environment. Every new cellular radio technology (e.g.: 3G and 4G) had been introduced to us a decade apart, and the technology lifespan is almost two decades since their commercial deployment. I would conservatively estimate that it may take a decade for us to experience the full capabilities of 5G (keeping spectrum availability, standards ratification etc. in mind).
