Success with 5G Communications Using “Vehicle Glass Mounted Antenna” for 5G Connected Car
— World’s first 28 GHz band compatible antenna achieves 8 Gbps super high-speed communications with high-speed vehicle —
Tokyo, July 25, 2018 — NTT DOCOMO, INC. (DOCOMO) and AGC Inc. (AGC) today achieved the world’s first1 8 Gbps 5G communications with a fast-moving vehicle equipped with “vehicle glass mounted antennas” (On-Glass Antennas) in a field trial conducted in conjunction with Ericsson Japan.
The 5G 28 GHz band compatible On-Glass Antennas used in the field trial were designed and developed by AGC. The antennas are not easily seen from the exterior and can be installed on glass surfaces without affecting the vehicle design.
Radio waves in the 28 GHz band have a large propagation loss and have difficulty propagating over long distances. By installing an On-Glass Antenna on the vehicle, radio waves above 6 GHz can be transmitted and received using the “beam forming function”, which concentrates radio waves in a specific direction, and the “MIMO function”, which improves communication speed by simultaneously transmitting different data from multiple antennas. This allows stable, high-speed communications even for vehicles in operation.
