Wireless Communications: Principles and Practice
Wireless Communications: Principles and Practice

Many fields of the industrial automation can be already served by wireless technologies. Due to the different requirements regarding the reliability, latency, number of nodes, node density and range to communication systems there is no uniform standard for wireless communication covering all domains of automation. It is to be expected in the future on a strongly increasing number of radio technologies and protocol stacks on different platforms and operating systems. Similarly it behaves within the classical wired field of the industrial automation. The number of Fieldbus standards for the different areas of applications is in the meantime only difficult to overlook. Uniform integration interfaces neither exist on the side of the radio technologies nor on that of classical control systems. This means direct additional complexity both for developers of wireless solutions and operators of industrial plants. This problem addresses the contribution and argues with the integration of wireless technologies into decentralized control systems. For relaying between both systems the architecture and the structure of a Convergence Middleware are presented, which abstracts the technology-specific details and makes a uniform integration interface available for wireless industrial communication systems.
