But more announcements regarding 5G advancements will surely come, because even though it will take many years before the first networks become commercially available the race between vendors and countries is very much on. For a vendor like Samsung -- whose mobile network equipment isn't as well known as its devices -- it is important to show technological prowess and that the company is in it for the long haul.
"Samsung is still small, but did really well last year compared to the market. It has the ambition to grow and part of that is wanting to be seen," said Sylvain Fabre, research director at Gartner.
Others have also announced 5G plans, including the European Commission. In February, vice president Neelie Kroes announced a €50 million (US$65 million) investment in research to deliver 5G mobile technology by 2020, with the aim of putting Europe back in the lead of the global mobile industry.
NTT DoCoMo's experiment, meanwhile, was sponsored by Japan's Ministry of Internal Affairs and Communications.
