Top 3 takes on 5G at the MWC18


MWC18 booth


MWC18 served 5G with a sprinkle of VR and IoT


It was again the time of the year to get your best suit on and head towards the booths shining brighter than diamonds. In other words, last week was the Mobile World Congress in the lovely Barcelona.


5G, 5G and then some more 5G


The show was all about 5G. We learnt what it does to help us, what it feels like and what it looks like.

5G can help save lives. This very practical benefit of 5G was showcased in a Nokia demo about an accident happening in the city traffic. The accident is immediately detected by AI. Using network slicing and AI to guide it, most capacity is instantly and automatically directed to communication to those needed to help, away from casual browsing. This means prioritizing saving lives over Netflix and Instagram, a true benefit of flexibility.



This is what do network slicing, self-optimizing networks and the like really mean. Combined with AI, they mean efficiency and speed with the capability to adapt to changing situations. The network structure is not a rigid structure, but instead an adaptable entity meeting the requirements that are given on that moment.


What does low latency feel like?

Now we know that it feels good, thanks to a demo by Ericsson showcasing remote controlling an excavator. First, the latency was set to 50ms, a typical 4G value. There was visible delay in the response, and the overall feel was unpleasantly sluggish. 5ms, a 5G latency, felt like actually being in control of the machine, then and there.


What does low latency look like?

It looks really good, showed the demo by Docomo. The controller donned a VR suit to guide a robot to paint some calligraphy on a canvas.


It apparently looks amazing, when used to enable VR. The ubiquitous VR demos were packed all through the show, with such long lines that our team had to forgo the entire experience.


15 000 steps per day

The new insights on 5G give us some food for thought, but what about the body, then? Our guys managed 15 000 steps per day (confirmed by their Polar Spartans) roaming the halls, gaining sore feet and fresh ideas. Nourishment was found at the restaurant My Way in the form of some delicious tapas.

Hannu and Petri met also some very serious businessmen at the Business Finland booth.

Bye Barcelona, see you next year!
