The RCU includes a reading device and a driver. The reading device is configured to read, from a memory inside the antenna apparatus, when the antenna apparatus is communicatively connected with the RCU, antenna information of an antenna controlled by the antenna apparatus and configuration data corresponding to the antenna. The antenna information includes the antenna serial number and the antenna model of the antenna. The driver is configured to control the antenna apparatus to adjust an electrical down-tilt angle of the antenna in accordance with the configuration data. ## Claims ### Claim 1 An antenna system comprising an antenna apparatus: the antenna apparatus comprising: an electrical tilting antenna; and a radio frequency identification (RFID) tag coupled to the electrical tilting antenna, with the RFID tag storing antenna information about the electrical tilting antenna and storing configuration data corresponding to the electrical tilting antenna, the antenna information including an antenna serial number or an antenna model of the electrical tilting antenna, and the configuration data defining a moving length specific to the antenna serial number or the antenna model. ### Claim 2 (depends on 1) The antenna system according to claim 1, further comprising: a remote control unit (RCU) in communication with the antenna apparatus, with the RCU configured to: read the antenna information and the configuration data from the RFID tag; and control movement of the electrical tilting antenna according to the moving length of the configuration data to set an electrical down-tilt angle of the electrical tilting antenna. ### Claim 3 (depends on 2) The antenna system according to claim 2, wherein the RCU is comprised in the antenna apparatus. ### Claim 4 (depends on 3) The antenna system according to claim 3, wherein the RCU includes a motor configured to control the movement of the electrical tilting antenna. ### Claim 5 (depends on 3) The antenna system according to claim 3, wherein the antenna information is provided from the RFID tag to the RCU through wireless communication. ### Claim 6 (depends on 3) The antenna system according to claim 3, wherein the antenna information is read by the RCU without manual input. ### Claim 7 (depends on 3) The antenna system according to claim 3, wherein the RCU includes a RFID reader for reading the antenna information stored in the RFID tag. ### Claim 8 (depends on 7) The antenna system according to claim 7, wherein the antenna information is automatically sent to the RCU upon installation of the electrical tilting antenna. ### Claim 9 (depends on 7) The antenna system according to claim 7, wherein the antenna information is automatically read by the RCU upon installation of the electrical tilting antenna. ### Claim 10 (depends on 7) The antenna system according to claim 7, wherein the antenna information is stored in the RFID tag inside the antenna apparatus prior to installation of the electrical tilting antenna. ### Claim 11 (depends on 3) The antenna system according to claim 3, wherein the RCU includes a RFID reader for reading the antenna information and the configuration data stored in the RFID tag. ### Claim 12 (depends on 2) The antenna system according to claim 2, wherein the RCU is external to the antenna apparatus. ### Claim 13 (depends on 12) The antenna system according to claim 12, wherein the RCU is in communication with a motor configured to control the movement of the electrical tilting antenna. ### Claim 14 (depends on 12) The antenna system according to claim 12, wherein the antenna information is provided from the RFID tag to the RCU through wireless communication. ### Claim 15 (depends on 12) The antenna system according to claim 12, wherein the antenna information is read by the RCU without manual input. ### Claim 16 (depends on 12) The antenna system according to claim 12, wherein the RCU includes a RFID reader for reading the antenna information stored in the RFID tag. ### Claim 17 (depends on 12) The antenna system according to claim 12, wherein the RCU includes a RFID reader for reading the antenna information and the configuration data stored in the RFID tag. ### Claim 18 (depends on 12) The antenna system according to claim 12, wherein the RCU automatically reads the antenna information upon installation of the electrical tilting antenna. ### Claim 19 (depends on 12) The antenna system according to claim 12, wherein the antenna information is automatically sent to the RCU upon installation of the electrical tilting antenna. ### Claim 20 (depends on 12) The antenna system according to claim 12, wherein the antenna information is stored in the RFID tag inside the antenna apparatus prior to installation of the electrical tilting antenna.
