GSM Friendly in details

We live in a connected world. However, onboard networks systems can be expensive. This why Saint-Gobain Sekurit Transport has developed a solution so end-users can stay connected during the journey. 

The wave and signal attenuation through standard glazing is around 3 Db, but the thermal improved coated glass works as a shield, and signal reception is heavily impacted (-30DB).

In order to keep comfort while improving connectivity, we have developed GSM friendly to improve the signal behavior through the coated glazing.

Thanks to a brand-new laser processing machine, we are able to partially erase the coating (only 5% of the coating is erased). The thickness removed from the surface is 30 microns, the same thickness of a hair! The comfort properties are kept and the signal behavior is improved (signal attenuation -5 to 8 Db)

For operators, the costs of infrastructure and use of the onboard network are reduced.

GSM Friendly technology can be used with all coated glass solutions.
