AGC, Ericsson and Domoco have achieved what is believed to be the world’s first 5G mobile telecommunications using antennas embedded in glass to transmit and receive 28 GHz radio signals. Tests using a vehicle fitted with multiple glass antennas and travelling at speeds of around 30 km/h were successfully completed in April.
5G radio signals in the 28 GHz band are seriously weakened when they pass through car windows to the interior. In addition, radio waves from urban 5G base stations reach the vehicle from various directions. The new AGC glass antennas were therefore used in multiple positions on the test vehicle including the windshield, side windows and rear window. The tests confirmed that these antennas switch seamlessly as the car moves, enabling 5G data to be transmitted and received in ideal directions with maximum signal strength and stability.
These AGC 5G glass antennas are very small and transparent, allowing them to be fitted discreetly, without spoiling the vehicle’s appearance or the passengers’ line of vision. Watch the test being carried out:
