DoCoMo, Japan's largest mobile operator, and
Nokia, the world's third biggest telecom equipment maker, said
they will be demonstrating their early technical progress on 5G
radio equipment at the Mobile World Congress show here this
week.
The companies said they have achieved super-fast data
transmission speeds of higher than 2 gigabits per second in a
joint indoor trial using Nokia Networks' radio technology
operating in the 70 gigahertz spectrum band.
By contrast, current 4G network specifications promise download
speeds of up to 300 megabits per second. Although practical
commercial speeds are typically far lower than that, 4G has
fueled strong demand for watching TV and video on phones.
They plan an outdoor 70 GHz trial later this year.
This band of airwaves is on a range of spectrum from 10 to 100
gigahertz that the International Telecommunications Union is
expected to free up by 2019 for use in fifth generation mobile
networks.
"This development underscores (DoCoMo's) readiness to deliver a
state-of-the-art 5G network in 2020 and beyond," the companies
said in a joint statement.
