T-Cell Czech Republic exams clear glass antennas and home windows

PRAGUE – T-Mobile Czech Republic and AGC have successfully completed the first tests of WAVEATTOCH, a new type of antenna for cellular networks. The WAVEATTOCH antenna was developed for easy installation directly on glazed facades. Once installed, it helps improve the quality of coverage and capacity of cellular networks, including 5G, especially in historic city centers, where installing traditional antennas on the walls of houses is inappropriate. Since the WAVEATTOCH antenna is made of glass and is therefore transparent, it fits discreetly into urban landscapes.

Meeting the capacity requirements of existing cellular networks and future 5G technologies, especially in densely populated areas, is a major challenge for operators. Installing traditional antennas on walls is not only time-consuming and costly, it is often impossible due to rules protecting cultural heritage in historic city centers. To this end, T-Mobile has teamed up with AGC to test its unique and innovative glass antenna.

The antennas were tested in conjunction with another unique AGC solution: WAVETHRU, a thermal insulating window glass whose surface has been processed to allow radio signals to penetrate and circulate in buildings more efficiently. WAVETHRU drastically reduces the signal attenuation through the glass by a factor of 10 to 100 (depending on the frequency band of the signal) while maintaining the most important thermal insulation properties. The solution has potential applications not only in the construction industry but also in other situations where thermal insulation glass with a metal coating is used and connectivity is required? for example in modern railroad cars.

The test was carried out earlier this year and involved placing WAVEATTOCH glass antennas at a height of approximately 10 meters on the windows of T-Mobile’s headquarters in Roztyly, Prague. At the same time, the existing double-glazed windows were replaced by double-glazing that was processed with the WAVETHRU surface treatment in order to restore high-quality communication in the building. The tests covered the band of 1,800 MHz and 2,100 MHz and in particular supported the 4G network for voice and data services. The 2×2 MIMO panel antennas used during the test are completely transparent and have a thin frame. At first glance, they are easy to miss from the outside.

The initial results showed that the two innovative solutions tested are feasible and functional concepts that could help mobile operators and cities meet the growing demand for high-speed mobile internet access. The test confirmed that WAVETHRU improved signal quality and signal levels in the selected locations.
