The objective of this project is to define, specify, develop and demonstrate a multiservice communication system (data, voice and image) based on mobile infrared terminals for indoor industrial applications suitable for SME factories and broad-site plants. The project takes into account the need to interwork with the following environments: ESPRIT CNMA, MAP, TOP, and ISDN.
The system particularly addresses the need for mobility and for reliable communication in the presence of severe electromagnetic interference, as encountered in electrical power plants, sub-stations and other factories. It provides wireless infrared communication inside limited size cells, together with a backbone network linking all subsystems. Low-cost limit-feature terminals as well as high-performance, multiservice mobile terminals have been specified.
The project started with an assessment of user's requirements for large plants as well as small and medium enterprises. The results are grouped into requirements for the network, terminals, and gateways and environmental conditions. In addition, a state-of-the-art survey indicates the main problem areas in terms of technologies and techniques.
Based on these results, a communication system has been defined that includes asynchronous and synchronous data streams as well as isochronous ones. ISDN is chosen as the basis for the system architecture. The protocols used fit as closely as possible to those of ISDN, and corresponding services can be implemented. The main aspects of the project are the infrared technology and the communication system. For the latter, results from project 2146 (DAMS) have been considered. Two types of terminals have been developed: a mobile ISDN voice terminal, and a ISDN-VME-board to connect terminals to the FCP network.
In a pilot site demonstrator a mobile vision robot and also the host system in the control room are equipped with one ISDN-VME-board to establish a wireless link between them by means of diffused infrared light. In addition, voice communication between a phone connected to the host system via the ISDN-VME-board and a mobile ISDN voice terminal can be done.
