Detecção de movimentação atípica de bovinos através da monitoração da intensidade de sinais de radiofrequência

Cattle theft is a national and growing problem in Brazil. It is known that, during theft, animals move atypically, changing the conditions of propagation in the environment, impacting the amplitude of the radiofrequency signals received at the location. In this paper, we investigate the feasibility of using the observation of radiofrequency signals received in the environment as a method of detecting thefts. Preliminary results of field tests, conducted on a cattle farm, indicated that the behavior of radiofrequency signals reflects the behavior of animals, presenting a promising potential for the detection of cattle theft.
