Small cell shipments will exceed macrocells in 2016, and total shipments will reach nearly 15 million units through 2019 according to ABI Research. However, the research company said mobile operators must act to address the increased security risk that these macro small cells will bring. The company warned that while small cells are inevitable parts of future mobile networks, IP-based backhaul and location risks leave the network exposed to various possible attacks. Small cells are compelling targets for attacks against subscribers and operators. Ranging in severity, security threats include data privacy threats, service fraud, denial of service, and operation malfunctioning. Report
