Whilst the premise of network slicing is straightforward the nuts-and-bolts is anything but. In supporting 5G applications, carriers need to deliver a customised 5G service with all the advantages of network slicing, small cells and coverage. With such complexities, is it possible to keep it simple? As massive IoT, virtual reality and augmented reality puts pressure on the network, what impact will network slicing have on infrastructure requirements? Will there be even more need for infrastructure in the future, and in the quest for tailored and intelligent connectivity, could the rise in private networks be a disrupter or a new opportunity for carriers?
