Commercial cellular networks emerged from the wired public switched telephone networks (PSTN) in an evolutionary manner. Market pressures fueled upgrades in bandwidth and functionality. Four decades later, these networks maintain historical artifacts from PSTN networks, and the artifacts work against the fundamental needs of today’s wireless systems. Noncellular wireless networks are used beneficially within geographically limited domains (enterprise, at home), but such networks lack the architecture to scale geographically.

In this paper, we step back and re-evaluate existing wireless network architectures, identifying inherent limitations and offering a new set of architectural principles that, we contend, will lead to significantly improved overall system performance and scalability. Based on these principles, we propose the CROSSMobileSM architecture that is enabled by controlled cross-layer information exchange between radio, network, and application layers (both on-device and in-cloud), coupled with information-owner-based privacy and security controls. We discuss how this architecture can provide increased value to equipment and device manufacturers, application and network service providers, and end users. We close by outlining a number of open research questions.
