During the development and validation phase it has become obvious that further development and validation of wireless technologies in industries is essential to meet industrial requirements and to have maximum chances of industrial exploitation. This affects mainly to the increase of the localisation accuracy of the wireless localisation system, and to the investigation of effective measures to increase the robustness of wireless technologies, also concerning coexistence.
Original Objectives
 Achievements and Results Work Package 3 has dealt with wireless communication technologies for VAN project. Due to the specific industrial environmental and dynamic requirements for automation, the standard office implementation of wireless communication cannot cover all scenarios since they are optimised for office communication technologies only. Therefore, an investigation, identification, and implementation of feasible technologies and standards to provide a base for wireless technologies for industrial environment have been performed. The first task in WP3 focused on a survey of existing wireless technologies and industry specific requirements. It described the fundamentals of wireless industrial communication from a VAN point of view. In the context of Task 3.2 suitable wireless technologies for VAN have been defined. The goal was to cover all requirements of the different applications with only a few wireless technologies. One important finding was that most requirements could be covered mainly by four different wireless technologies. A concept on how to integrate wireless into the VAN ASE landscape has also been defined as part of Task 3.2. As part of Task 3.3, a localisation approach based on wireless technologies has been introduced. Details on the learning approach and its suitability for industry environments have been worked out. This approach was also part of the implementation work done in Task 3.4. Furthermore, wireless devices have been enhanced by additional IEC 61158 functionality, which is the basis for VAN enabled devices. Exhaustive coexistence measurements have been performed in Task 3.5. All possible combinations of the proposed wireless technologies have been investigated. Simple rules for coexistence of different wireless technologies were derived from the measurement results.
