DOCOMO reports success with 5G test using vehicle glass-mounted antenna on connected car

摘要

Japanese mobile operator NTT DOCOMO, Ericsson Japan and glass solution provider AGC have claimed a 'world first' in a 5G test using a 28GHz band antenna on a 5G connected car. The trials achieved 8Gbps 5G communications with a fast-moving car equipped with vehicle glass-mounted antennas ('On-Glass Antennas'). In a press release, DOCOMO said the field trial used On-Glass Antennas designed and developed by AGC, which can be installed on glass surfaces without affecting the vehicle design. The release read: 'Radio waves in the 28GHz 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 6GHz 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.'
