| Abstract: | Current Wi-Fi standards provide theoretical data transfer rates similar to common wired connections. In practice, these rates 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 jitter and reduced data transfer rates. An extensive series of measurements has been conducted to identify the parameters with the strongest influence on latency and transfer bandwidth. As a result, we have derived a concept for a low-latency wireless system which tackles the mutual trade-off between low latency and reliability. Our reliability mechanism is different from the IEEE 802.11 by not forcing acknowledged packet transmission, but providing a novel image reconstruction scheme. Without the need for infrastructure like an Internet connection or an access point, 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. |
