This product is a next-generation Point of Interface (POI) for in-building wireless systems that not only delivers mobile signals from external base stations but also captures and reuses energy that is normally wasted. In conventional systems, over 99.9% of incoming signal power is lost as heat. Using a proprietary GaN semiconductor circuit, this product recovers more than 50% of that energy and converts it into electricity to power the system itself. As the first POI with built-in energy harvesting, it reduces the need for external power, lowers heat, and enables more efficient, compact, and sustainable indoor communication systems.
