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

NTT DOCOMO, AGC and Ericsson announced today that they 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. 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 antenna embedded in synthetic fused silica glass 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.
