A smart building is an instrumented structure in which applications are cognizant of the contextual status of the environment, occupants, energy requirements, service needs, security, and safety.
Aruba has a number of partnerships with IoT vendors that offer smart building solutions that connect to and leverage the Aruba infrastructure.
