Mobile phone group Vodafone has conducted a successful trial connecting next-generation 5G smartphones to its network for the first time as it prepares to launch 5G in some European cities later this year, it said on Wednesday.
Vodafone said it had made an ultra-high-resolution 4K video call during trials in Madrid and Barcelona, at speeds 10 times faster than current 4G technology, reports Reuters.
Worldwide commercial launch of 5G is expected in 2020, and some countries led by the United States, China and South Korea have already announced or carried out deployments on a small scale.
The technology is likely to be used first for private or industrial networks, with national roll-outs for consumers some way behind.
