The present publication describes a localization concept to determine the 3D Position of passive UHF-RFID transponders. The importance of accurate location information significantly increases with Industry 4.0 in mind. Various applications in production and logistics require the exact location for monitoring the processes and thereby increasing the quality and reliability. The presented system consists...
Localization of UHF RFID tags in an industrial environments is difficult due to signal reflections and multipaths caused by steel and metal objects. Existing solutions have shown decent accuracy for small distances but fail to maintain the accuracy as the distance between the antenna and the tag increases. In this paper, we describe a novel UHF RFID localization approach based on location fingerprinting...
In wildlife scenarios UHF transponder can be used to mark and localize animals over a large distance. Therefore, the size of the marking device has to be appropriate besides the wavelength is much bigger than it. Ceramic chip antennae enable a compact design in UHF applications. Due to the unknown position of the transponder in wildlife localization applications an omni-directional radiation pattern...
The present publication describes the development of an active UHF RFID localization system concerning small size RFID transponders with an integrated GPS module for fawn saving during pasture mowing. The localization of a conventional active UHF RFID transponder has obvious drawbacks in the needed hardware on the reader side. The transponder sends only its label and no additional position information...
Autonomous solar powered transponders or wireless sensor nodes operate well in high sun irradiation whereas in low light conditions the efficiency of the solar cell decreases and full operation is not guaranteed any longer. This is likely to happen in wildlife scenarios particularly in shaded areas or in indoor environments. The presented transponder concept is designed to face exactly these challenging...
The present publication addresses the RFID transponder distance estimation based on received signal strength (RSS) in the application of fawn saving. During the pasture mowing fawns shall be protected from mowing machines by a RFID transponder localization system. At the moment the localization system is set on direction-of-arrival only. To facilitate the search process the localization capabilities...
The present publication describes an innovative concept for fawn saving during pasture mowing in spring time. Conventional approaches like scaring by dogs or scarecrows are ineffective and time consuming especially for large areas. Other technical solutions have different drawbacks or insufficient search performance. Within the active UHF RFID localization system the processes of identifying fawns...
