Modern society is increasingly depending on wireless communications and applications utilizing it i.e. instant messaging, web browsing, multimedia streaming and IoT solutions. At the same time governmental energy saving regulations are tightening. In order to respond to these the construction industry has developed new constructions methods such as low-E windows and aluminium coated insulators. Unfortunately these cause modern buildings to attenuate communications signals dramatically. StealthCase Oy is founded to design construction supplies in a way that mobile communication signals pass through wall unattenuated.
