SCADA for the Rest of Us: Unlicensed Bands Supporting Long-Range Communications
The authors are on the cusp of the next big wave in Internet and wireless technology for the mass market: the emergence of ubiquitous smart environments capable of automated sensing and interaction with the physical world around one.. A critical ingredient for this future is the deployment and availability of wireless control network infrastructure and services. Most discussions of the future smart environment focus on large systems managed by large corporate or public entities: Smart power grids, smart freshwater and wastewater management, and so on. The distributed communications and control mechanisms that automate these infrastructure systems are called SCADA (for "Supervisory Control and Data Acquisition"). Most work on SCADA has correspondingly considered the focused networks that support a single large system or application.
