AiRISTA’s Reference Beacon Units (RBU) are designed to wirelessly provide location reference data to AiRISTA’s family of active RFID and RTLS tags. The RBU transmits Wi-Fi or BLE beacons along with its own unique ID. Any AiRISTA active tag equipped with the reference signal receiver in range of the wireless signal can detect and interpret the received data and transmit the information to AiRISTA’s UVS software for location determination.
