This document discusses the opportunity for ATCA in femtocell gateways. It notes that mobile broadband is driving major network growth, but capacity is not keeping pace. Femtocells and LTE can improve spectrum reuse by delivering smarter, faster, and cheaper mobile broadband through small cell access points. ATCA is well-suited for femtocell gateways due to its reliability, scalability, and ability to support both 3G and LTE standards. The document promotes ATCA solutions for femtocell gateways and their ability to aggregate data streams from many femtocell access points.
