While many 5G demos show technical progress, few wow an audience in the same way Vodafone did at its Future Ready press conference, unveiling the UK’s first live holographic call.

After CTO Scott Petty set the stage with a number of impressive announcements indicating Vodafone is perhaps not the cumbersome beast we have come to expect, an underwhelming skit involving a VR headset and England Women’s football captain Steph Houghton led irritable journalists towards a slumber. But with a drop of the curtain, the demo was unveiled in all its glory. And it was incredibly impressive.

5G will enable remote surgery and 4K gaming experiences, though there is little excitement generated through this announcements nowadays. Using 5G technology to underpin the experience, Houghton, who was located in a Manchester studio at the time, appeared in Vodafone’s Newbury HQ as a 3D hologram. The image was sharp, the lag was unnoticeable and all of a sudden the audience was engaged. It was cheesy, as Houghton showed off her skills and answered some questions from 11 year-old football fan Iris, but it was an excellent demonstration of the power of 5G.

“Vodafone has a history of firsts in UK telecoms – we made the nation’s first mobile phone call, sent the first text and now we’ve conducted the UK’s first holographic phone call using 5G,” said Vodafone UK CEO Nick Jeffrey.

What is worth noting is this is not a world first, KT is developing hologram calling as a flagship 5G service and has conducted a test call between Verizon CEO Lowell McAdam and its own CEO Hwang Chang-gyu. That said, this should not take the shine off an impressive demonstration.

Some might look at such an idea and scoff; what is the opportunity aside from showing off what the network is capable of, surely this isn’t realistic for the real world? But why not?

A decade ago it would have been inconceivable to consider video conferencing as a mass market product. In the early years it was reserved for the board room, due to the price of equipment and the software to make it work. Nowadays, Skype calling is as common as a sausage sandwich. We’re not suggesting hologram calling is going to be commonplace over the next couple of years, but who knows what is possible when the price point of technology starts tumbling down.

CTO Petty referred to the famous Bill Gates quote when discussing the potential for a mass market product; most people overestimate what they can do in one year and underestimate what they can do in ten. The mind runs wild when you consider what could be possible; GP consultations from your living room, distance learning would take on a new spin and some sports events, boxing for instance, could take the live audience from tens of thousands to millions by setting up holographic arenas all over the world. Healthcare, education and entertainment could be completely revolutionised.

It’s been a while since a 5G demonstration has genuinely got a room full of journalists excited; well done Vodafone!
