If you believe that communication networks of the future--serving both consumers and businesses-- will be built on cloud (edge and core), low latency and ultra-high bandwidth, then it is clear why 5G and other next-generation networks matter.
By definition, 5G will feature latencies in the low single digit milliseconds (150 milliseconds is how long it takes to blink your eyes; 50 milliseconds long has been the standard for switching from a primary to backup connection without users detecting the change), with bandwidths measured in gigabits per second.
We often think about 5G as of value primarily for consumer use of smartphones. It has equally-important implications for enterprise communications. If one assumes the standard for enterprise inside-the-building communications has been cabled Ethernet networks, in the future the default will be untethered connections of several types.
By 2025, estimate researchers at Nokia Bell Labs, 30 percent of enterprise premises links will use 5G. About 29 percent of connections will use Wi-Gig, while 17 percent of connections might use 3G or 4G. Only about 22 percent of connections will use Wi-Fi.
It might come as a bit of a shock to many observers that the future of enterprise local networking is untethered, but that is what Nokia Bell Labs researchers now believe.
Of equal importance, perhaps, is the role expected to be played by mobile platforms (5G, 4G). Mobility platforms (public or private) might represent nearly half of enterprise data volume by 2025.
Wi-Fi still will matter, but perhaps less than you might expect, representing 22 percent of data volume.
