TECHNOLOGY REVIEW:
The fifth generation of mobile communications technology will see the end of the “cell” as the fundamental building block of communication networks.
Today we get some interesting speculation from Federico Boccardi at Alcatel-Lucent’s Bell Labs and a number of pals. These guys have focused on the technologies that are most likely to have a disruptive impact on the next generation of communications tech. And they’ve pinpointed emerging technologies that will force us to rethink the nature of networks and the way devices use them.
The first disruptive technology these guys have fingered will change the idea that radio networks must be made up of “cells” centred on a base station. In current networks, a phone connects to the network by establishing an uplink and a downlink with the local base station.
That looks likely to change. For example, an increasingly likely possibility is that 5G networks will rely on a number of different frequency bands that carry information at different rates and have wildly different propagation characteristics.
So a device might use one band as an uplink at a high rate and another band to downlink at a low rate or vice versa. In other words, the network will change according to a device’s data demands at that instant.
At the same time, new classes of devices are emerging that communicate only with other devices: sensors sending data to a server, for example. These devices will have the ability to decide when and how to send the data most efficiently. That changes the network from a cell-centric one to a device-centric one.
I think out of force of habit, we'll still call it a "cell phone."
