“…Instead of a complete package loss, only a fraction of the collection of bursts might be corrupted, which can be reconstructed by means of error-correction codes at the receiver side. It is only due to this specialized telegram-splitting technique 16 that a long-range transmission under extreme power-restrictions and vastly occupied frequency channels becomes possible.…”

“…As a consequence of the extreme energy limitation of the MN, we ensured the required Signal-to-Noise-Ratio (SNR) by counterbalancing the rate and the desired transmission distance. The combination of the hybrid modulation, the channel encoding procedure 17, 45 and the ‘Telegram-splitting’ technique 16 enables an ultra-low power long-range transmission without additional expenditure of energy. The long-range bursts were received at two long-range receivers, which were deployed on exposed sites (rooftops) at distances of ca.…”

AbstractRecent advances in animal tracking technology have ushered in a new era in biologging. However, the considerable size of many sophisticated biologging devices restricts their application to larger animals, while old-fashioned techniques often still represent the state-of-the-art for studying small vertebrates. In industrial applications, low-power wireless sensor networks fulfill requirements similar to those needed to monitor animal behavior at high resolution and at low tag weight. We developed a wireless biologging network (WBN), which enables simultaneous direct proximity sensing, high-resolution tracking, and long-range remote data download at tag weights of one to two grams. Deployments to study wild bats created social networks and flight trajectories of unprecedented quality. Our developments highlight the vast capabilities of WBNs and their potential to close an important gap in biologging: fully automated tracking and proximity sensing of small animals, even in closed habitats, at high spatial and temporal resolution.

“…As a consequence of the extreme energy limitation of the mobile node, we ensured the required signal to noise ratio (SNR) by counterbalancing the rate and the desired transmission distance. The combination of the hybrid modulation, the channel encoding procedure [21,60], and the "Telegram-splitting" technique [20] enables an ultra-low power long-range transmission without additional expenditure of energy. The long-range bursts were received at 2 long-range receivers, which were deployed on exposed sites (rooftops) at distances of approximately 200 to 1,800 m (retirement home; 522 7'13"N 13˚30'19"E) and 3,300 to 4,500 m (cogeneration plant; 52˚29'18"N 13˚29'36"E) to the proximate respectively ultimate border of the urban forest where the roosts of the tracked bats were located (forest center approximately 52˚27'13"N 13˚29'40"E).…”

“…A Forney interleaver with 24 branches distributes one payload byte over 24 wake-up bursts, resulting in a time interleaved transmission of each long range telemetry packet of almost one minute. This approach adheres to the idea of the so-called Telegram Splitting concept as presented in [ 45 , 46 ]. Thereby, information is spread within the time (and frequency) plane in a burst-like fashion.…”

In this paper, the BATS project is presented, which aims to track the behavior of bats via an ultra-low power wireless sensor network. An overview about the whole project and its parts like sensor node design, tracking grid and software infrastructure is given and the evaluation of the project is shown. The BATS project includes a lightweight sensor node that is attached to bats and combines multiple features. Communication among sensor nodes allows tracking of bat encounters. Flight trajectories of individual tagged bats can be recorded at high spatial and temporal resolution by a ground node grid. To increase the communication range, the BATS project implemented a long-range telemetry system to still receive sensor data outside the standard ground node network. The whole system is designed with the common goal of ultra-low energy consumption while still maintaining optimal measurement results. To this end, the system is designed in a flexible way and is able to adapt its functionality according to the current situation. In this way, it uses the energy available on the sensor node as efficient as possible.
