DOCOMO, AGC and Ericsson Achieve World's First 5G Communication Using Glass Antenna for 28 GHz

JCN Newswire (English)
NTT DOCOMO, INC., AGC Inc. and Ericsson have achieved what is
believed to be the world's first 5G mobile telecommunications using
an antenna embedded in synthetic fused silica glass to transmit and
receive 28 GHz 5G radio signals for stable, high-speed mobile
communication in buildings, vehicles and trains.
The antenna was used to verify 28 GHz 5G mobile communication with
downlink speeds averaging 1.3 Gbps within a 100-meter range and
reaching a maximum of 3.8 Gbps at 400 MHz. The verification tests,
which used a vehicle fitted with multiple antennas and traveling
about 30 km/h, were conducted in the Sumida area of Tokyo between
April 22 and May 28.
Radio signals in the 28 GHz band are more linear than 4G LTE
signals, so they are not strong enough to adequately penetrate
windows in buildings, vehicles and railway cars. The new glass
antenna can be attached to window surfaces to enable radio waves to
be received and relayed in ideal directions for stable, high-speed
5G communications under challenging indoor and in-vehicle
conditions.
Antennas were used in multiple spots on the test vehicle, including
the windshield, side windows and rear window, enabling data to be
transmitted and received in ideal directions for maximum signal
strength. As a result, stable, high-speed communication was
achieved even in urban areas where signals were blocked or
reflected by obstacles.
The 5G glass antenna's small size and transparent appearance allow
it to be installed unobtrusively in buildings, vehicles, etc.
without impairing the installation object's appearance or design,
or people's line of sight.
Going forward, DOCOMO, AGC and Ericsson will continue to refine
antenna technology to enable the glass antenna to function
compatibly with Massive MIMO, a technology that uses multiple
antennas to transmit and receive data, aiming to achieve faster 5G
communication speeds and expanded 5G use under diverse
conditions.
