At least as Samsung sees matters, if 4G was intertwined with cloud computing, then 5G will be the era of edge computing. The reason is that mobile devices used by humans and machine sensors will have limited computation capability.
As in the past, computing and communications are functional substitutes: Communications can be used to provide access to computing, or computing can be used to avoid use of communications.
So as computational intensity continues to grow, one solution is to offload computation tasks to more powerful devices or servers from actual end user devices or sensors.
In the case of real-time intensive computation tasks, hyper-fast data rate and extremely low latency communications are required. And that means edge computing, in the 5G era.
As with all prior digital generations, better latency performance and higher bandwidth--by at least an order of magnitude--can be expected from 6G. As we will approach zero in terms of air latency, we might have to start thinking about “negative latency,” the ability of the network and computing infrastructure to anticipate problems and prevent them from occurring.
That obviously will be a virtual concept, as the latency performance advantage will not derive in a physical sense from the network but from avoided latency issues. Samsung notes that the interest in multi-access edge in the telecom industry is precisely this ability to support real-time and mission-critical functions with computing at the edge of the network.
