Apparatus, method, and system to dynamically deploy wireless infrastructure
CRYSTAL “Cognitive radio you share, trust and access locally” (CRYSTAL) is a virtualized cognitive access point that may provide for combining multiple wireless access applications on a single hardware platform. Radio technologies such as LTE (Long-Term Evolution), WiMax (Worldwide Interoperability for Microwave Access), GSM (Global System for Mobile Communications), and the like can be supported. CRYSTAL platforms can be aggregated and managed as a cloud, which provides a model for access point sharing, control, and management. CRYSTAL may be used for scenarios such as neighborhood spectrum management. CRYSTAL security features allow for home/residential as well as private infrastructure implementations.
