Abstract:
Caused by increasing demands for wireless devices in the last decade, license-free bands such as the 2.4 GHz ISM band become more and more crowded. As a consequence, interferences are inevitable. To avoid impairments caused by interferences, there have to be mechanisms to prevent coexisting systems to interfere with each other in license-free bands. Especially in industrial application fields, a reliable and deterministic medium access is required. In this paper, we evaluate an inter-system cooperation approach, which is designed to be aware of interferences, to ensure reliable real-time communication and further to protect investment for existing wireless systems. In a selected industrial scenario, it outperforms a non-cooperative approach especially in presence of interference. Further, it ensures a reliable communication for more than 99% of the real-time data packet transmissions also in presence of interference.
