In time for MWC the International Telecommunication Union, a UN agency, agreed on the specifications for 5G: speeds must be up to 20 gigabits per second, enough to download a movie in a few blinks of an eye.
At the show, makers of networking gear, such as Samsung, announced products for the first 5G networks.
These are expected to launch in 2018, mostly in South Korea and in Japan, where the new wireless technology is expected to be shown off during the Tokyo Olympic Games in 2020.
Much still needs to be invented to make 5G a reality.
Mobile carriers will, for instance, have to rejig their networks to make them more like a “computing cloud”.
The idea is that network operators, just like providers of computing power, should be able to cook up new telecoms services within seconds.
One technique is called “slicing”, meaning phone networks can be divided up to serve different purposes, such as providing superfast connectivity for self-driving cars or reliably hooking up connected devices as part of the Internet of Things.
Mobile innovation is not doomed to be hidden in the network.
But you will have to look more closely to spot it.
In Barcelona fingerprint readers appeared in smartphones costing less than $100.
If these move to even cheaper devices, it would be a boon to people in developing countries who could easily authenticate themselves online.
Another development was that 360-degree cameras are becoming smaller and cheaper.
The matchbox-sized Giroptic iO, which attaches to a smartphone, costs $260.
Expect another dimension of selfies, which some already call “surroundies”, and, inevitably, new sorts of selfie sticks.
