The solution that makes 5g efficient – New Technology

       

Ericsson 5g-venture company’s main research projects. It is also the country’s most important, because Ericsson is one of the country’s biggest employer by far the most employees who work with research and development.

A fiasco 5g project would also strike hard against Swedish exports in the long term. The telecom giant is the country’s largest exporter.

For both Ericsson and Sweden, it is therefore extremely important that the Swedish mobile giant also succeed with the next mobile generation, the fifth in the order, 5g.

The competition is cutthroat . Chinese main opponent Huawei is now investing SEK 5 billion at 5g research over five years. There is a lot of money at such an early stage. 5g standard will be completed only in 2020. Exactly how much Ericsson invests do not want to reveal.

How is it going for Ericsson 5g-research? New Technology visited Kista to get an update and got to see the new 5g prototype, the first of its new radio interface, dubbed NX after Star Trek’s starship. The new base station weighs 18 kilos and can fit in a suitcase. The idea was that new technology would be the first newspaper in the world that would get a demonstration of the new miracle. But something failed.

– But we know that everything works. This particular box will be soon sent away to be tested in the mobile network of one of our customers, says Mats Norin, portfolio manager at Unit Radio at Ericsson.

So far, Ericsson has only produced a handful of similar prototypes . The first is already skeppad of NTT Docomo in Japan, where it will be tested in the spring.

A lot has happened since Ericsson’s researchers for the first time described the 5g of New Technology. It was the spring of 2013, then it was the tender specifications which were presented:

One hundred times higher data rate than the 4G network, a thousand times higher data volumes, one-tenth as long response times, ten times longer battery life, a hundred times more people online gadgets and better reliability.

– With the new 5g prototype we can demonstrate that we meet the requirements, assures Håkan Andersson, head of 5g Radio at Ericsson.

In the first 5g- Ericsson experiments used the same principle for the connectivity of the mobile phones in 4G networks, where mobile phone hooked up to a single base station. Only when the cell phone was moved closer to another base station was handed over the data signal to the new base over so-called “handover”.

But in the new 5g prototype Ericsson uses a completely new solution. There is talk in the industry about a paradigm shift, as 5g handsets will be connected to several base stations at the same time.

– The cell phone in 5g network is completely decoupled from the base station. It will no longer know from which base station the data signal comes, says Mats Norin.

There are several reasons why Ericsson chose to use the new solution. Partly because it 5g becomes more important to have a connection in reserve. Partly because it thus possible to increase the speed further. (See more explanation in the graphic at right.)

The remaining challenge is the business model for 5g, says Mats Norin.

– Technically, we have good track. But who will provide the new 5g services? And who pays?

What is Ericsson’s main competitors in 5g he does not hesitate nor over. It’s Huawei and Nokia. And he is equally convinced of the importance of being the first 5g?

– Absolutely, it’s very important, says Mats Norin.
