Femtocells provide an essential solution for improving mobile broadband coverage, capacity and reducing churn. They leverage a user's fixed broadband to provide indoor cellular coverage through a small home base station. Femtocell solutions involve femtocell access points and gateways to extend coverage from the macro network and offload traffic using the user's broadband backhaul. Trillium provides protocol software and reference applications to power femtocell solutions for both 3G and LTE networks.
