You're gonna be waiting a very long time before it's widely available like 4G. 5G has an extremely short range and the signal is easily blocked.I'm holding out making any giant changes until 5G really gets rolled out. If its what they say it will be, we will do everything through the cellular networks and speeds that make fiber or cable unecessary.
Mika Skarp, CEO at Cloud Street says: ""Yes, most certainly 5G will replace Ethernet, but it will do much, much more, and it needs to. Though 5G won’t replace the fibre backhaul any time soon, the shelf-life and cost of fibre, and the lowering cost and dramatically improved flexibility of virtualized RAN make increasingly prohibitive. Software Defined Networks (SDC) and Network Function Virtualization within the 5G world, whether supported by small cells or full size base stations will not only cut the last mile of fibre to the core network, but will also provide for an array of intelligent, adaptive and even application-aware features that will make it a true game-changer in telecommunications for consumers and enterprises alike.
