Some properties we have used include the received signal strength indicator (RSSI), Angle-of-Arrival (AoA), and time-of-arrival (TOA). http://grailrtls.sourceforge.net/

PSFK: In an effort to help dairy farmers better manage their herds, Danish technology firm, SmartFarming has developed an animal tracking and monitoring system called CowDetect. The system enables farmers to maintain a more meaningful account of individual animals by analyzing movement and eating patterns in real time. This data can be used to determine health, allowing farmers to treat or remove sick cows before they affect the wellness of the entire herd, as well as plan milking and fertilization schedules that can help maximize productivity.
