5G: wireline as much as wireless, and not all about constant connectivity

It is more meaningful, in many scenarios, to think of 5G as a new generation of connectivity, or a broader architecture, than just a radio upgrade. Fully virtualized, even sliced, networks; multiple air interfaces; dynamic access to multiple spectrum bands – all these and many more have their roots in the 4G HetNet, but will come to fruition in the next generation. However, that thinking can be extended further, to make the case that 5G will be as much about wireline as wireless, and may not always be much about connectivity. Wireline advances, such as high quality fiber and eCPRI, will be essential to provide backhaul and fronthaul for the dense, virtualized 5G RANs, but the ‘5G is wireline’ argument…
