NTT DOCOMO, INC. and Ericsson (NASDAQ:ERIC) announced today that
in a joint 5G technologies trial, the companies achieved a
cumulative 20Gbps of data throughput in an outdoor environment
using the 15GHz frequency band with two simultaneously connected
mobile devices of a downlink bit rate of over 10Gbps each, on
February 21. The data speed satisfies one of the key requirements
for future 5G commercial services.
The companies also succeeded in a separate trial on February 21,
data throughput exceeding 10Gbps at a distance of approximately 70
meters from the base station, or about 7 times farther than the
distance achieved in a past trial. Moreover, the data transmission
exceeding 9Gbps at a distance of about 120 meters from the base
station was also succeeded.
5G will use high-frequency bands, which are inclined to
experience attenuation in speed and capacity as they travel over
long distances.
The trial, which took place at the DOCOMO R&D Center in the
city of Yokosuka, Japan, utilized a specification defined jointly
by DOCOMO and Ericsson, and an Ericsson 5G Radio Prototype and user
devices, in place of mobile phones, from Ericsson.
The data speeds were achieved thanks to multi-beam
multiple-input multiple-output (MIMO) technology, which increases
data speeds by multiplexing radio waves simultaneously. Also, by
utilizing a beam-forming technique that incorporates beams, each
one consisting of 64 antenna elements to converge highly
directional long-distance signals on a single target, the
cumulative 20Gbps throughput was successfully transmitted.
