| Abstract: | Interactive wireless industrial or medical display applications require real-time capable low latency connectivity. On the other hand, the video links must be highly reliable. These two requirements, low latency and high reliability, are generally contradictory. The paper discusses methods for connecting industrial color displays with low latency, low bandwidth and high reliability over Wi-Fi. For well-established wireless standards like Wi-Fi, these requirements are hard to achieve, because of data retransmission after packet loss and channel congestion by other participants using the same frequency bands. As a consequence, unpredictable latency of data transfer is introduced and leads to substantial display jitter and reduced data transfer rates. An extensive series of investigations has been conducted to identify the parameters with the strongest influence on latency and transfer bandwidth of display connections. As a result, we have derived a concept for a low-latency wireless video transfer system, which tackles the mutual trade-off between low latency and reliability. Moreover Wi-Fi infrastructure like an Internet connection or an access point is not needed. Such a system has a variety of applications, especially in interactive scenarios like robot control, consumer devices, industrial process monitoring and medical imaging. The system is compared to other approaches and the respective advantages and drawbacks are discussed. |
