  abstract     = {{Wireless industrial environments are dominated by multipath propagation and interference. In order to handle spatial diversity, a possible approach is dividing the physical area into many small cells. The spatial diversity is turned into FDMA by utilizing different frequency bands for neighboring cells. A challenging use case with fast vehicles traveling over long distances in a short time is the packaging industry. It would require many fast handoffs for each vehicle. Thus, a small cell FDMA approach is not appropriate. Conversely, employing radiating lines eliminates FDMA-based handoff issues, and reduces multipath delay spread and signal attenuation compared to centralized approaches. Additionally, radiating lines perform well in high-speed, low-power and long-range environments. In this paper, we realize a novel radiating-line-based, high-reliable, real-time transmission system with near-field coupling. This wireless transmission method results in a frequency-flat, time-invariant radio channel for the given requirements. Employing antenna diversity results in significant improvements in the system's performance compared to single antenna solutions.}},

  abstract     = {{Industrial wireless communication in license-free spectrum bands such as the 2.4-GHz-ISM band suffer from motion and multipath effects, which cause a high time- and frequency-variant channel attenuation. Additionally, mutual interference from heterogeneous wireless technologies limits real-time capabilities of industrial wireless technologies. Therefore, performance validations of industrial wireless technologies within appropriate industrial wireless environments are necessary. In this paper, we present the first raw measurement data set publication of an industrial wireless environment characterization in a data repository for free public access to enable transparent industrial wireless technology validation and to enhance their comparability. We characterize the whole license-free 2.4-GHz-ISM band with a time resolution of 110 μs and a frequency resolution of 1MHz in a coexistence scenario with four antennas obstructed by robot arm movements. Additionally, the frequency and time variance of the measured channel attenuations are analyzed.}},
