Design and implementations series IX: Smartphone apps, network security, zigbee, and 40/100G ethernet technologies

Welcome to the ninth installment of the Design and Implementation (D&I) Series. The D&I Series was created with a specific goal to facilitate knowledge transfer between scientists and industry-oriented engineers. In contrast to the classic peer-reviewed, academically oriented articles on communication technologies, D&I articles focus primarily on the practical Lessons Learned information that is gained while designing, implementing, and deploying new communications products, services, and solutions.
