Abstract

MITIGAÇÃO DA INTERFERÊNCIA DO LEITOR DE IDENTIFICAÇÃO POR RADIOFREQUÊNCIA (RFID) ADJACENTE. A presente invenção se refere a um sistema de identificação automática de veículo (IAV) de identificação por radiofrequência (RFID) configurado para mitigar a interferência de sinal, o sistema compreendendo uma pluralidade de leitores RFID, compreendendo um primeiro leitor RFID e um segundo leitor RFID; e uma pluralidade de antenas, sendo que uma primeira antena é conectada ao primeiro leitor RFID e uma segunda antena é conectada ao segundo leitor RFID. Antes de o primeiro leitor RFID transmitir um sinal através da primeira antena, o primeiro leitor RFID testa um sinal de radiofrequência (RF) recebido da primeira antena e se o sinal de RF recebido atender os critérios de intensidade e frequência predeterminados, o primeiro leitor RFID inibe a trans-missão do sinal através da primeira antena.
