Wireless T-Mobile CR, AGC test transparent glass antennas, windows that lower signal attenuation Thursday 10 December 2020 | 17:17 CET | News T-Mobile Czech Republic and AGC have successfully completed initial testing of Waveattoach, a new type of antenna for mobile networks. The Waveattoach antenna was designed for easy installation directly on glazed facades. Once installed, it helps to improve the quality of coverage and the capacity of mobile networks, including 5G, especially in historic city centres, where installing conventional antennas on the walls of houses is inappropriate. Since it is made of glass and therefore transparent, the Waveattoach antenna blends discretely into urban landscapes.
