The most over-hyped tech ever, or an era-defining innovation?
* Correction: Sony Xperia XZ Premium rather than Z5
Opinion is divided on 5G at MWC 2017, with super-fast phones hinting at 5G speeds despite the big telecoms operators insisting that 5G networks are still years away.
What, exactly, is 5G for? Why do we need it? How will we use it? And how is it going to improve our lives? As usual with new tech, 5G is part-sales pitch, part-revelation, and part-stab in the dark. The Olympics will play a huge part; when Pyongchang 2018 and Tokyo 2020 roll around, the world will see what 5G looks like as super-fast Wi-Fi hits trains, and even enables real-time AR and VR streaming. Eventually it will super-charge home broadband and enable real-time 8K video calling apps. The connected world is about to get super-charged.
