IN THE computing clouds, startups can set up new servers or acquire data storage with only a credit card and a few clicks of a mouse. Now imagine a world in which they could as quickly weave their own wireless network, perhaps to give users of a fleet of self-driving cars more bandwidth or to connect wireless sensors.
As improbable as it sounds, this is the logical endpoint of a development that is picking up speed in the telecoms world. Networks are becoming as flexible as computing clouds: they are being turned into software and can be dialled up and down as needed. Such “cloudification”, as it is known, will probably create as much upheaval in the telecoms industry as it has done in information technology (IT).
IT and telecoms differ in important respects. One is largely unregulated, the other overseen closely by government. Computing capacity is theoretically unlimited, unlike radio spectrum, which is hard to use efficiently. And telecoms networks are more deeply linked to the physical world. “You cannot turn radio towers into software,” says Bengt Nordstrom of Northstream, a consultancy.
The data centres of big cloud-computing providers are packed…Continue reading
