DOCOMO, AGC and Ericsson Achieve World’s First 5G Communication

NTT DOCOMO, AGC, 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.

5G Communication

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.

In the future, DOCOMO, AGC and Ericsson will continue to refine antenna technology to enable the glass antenna to function compatible 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.
