No more dead spots in buildings: Fraunhofer ISE develops insulating glass transparent to radio waves

We have all been there: The moment we enter a building, we lose our mobile network. The culprits are modern double or triple insulating glass panes with thermal or solar control coatings. A team at Fraunhofer Institute for Solar Energy Systems worked with industrial partners to develop insulating glass that is transparent to radio waves, significantly improving the indoor reception for cell phone services such as LTE, 5G and GPS navigation. The technology will be presented at the BAU trade fair in Munich (April 17–22).
