Abstract: An electrical tilt apparatus is provided, to ensure that when a quantity of serial ports on a remote control unit (RCU) is limited, independent electrical tilt on RF signals is provided. The apparatus includes: an RCU, and at least one combiner unit and multiple phase shifters connected to the RCU. Each of the at least one combiner units is connected to a different serial port on the RCU and connected to at least two RF modules; receives, at each time, an electrical tilt signal from one of the RF modules, and sends the electrical tilt signal to the RCU. The RCU receives the electrical tilt signal from each combiner unit, and drives, according to the electrical tilt signal, a first phase shifter that corresponds to a first RF module to move.

Abstract: Radio frequency channel connection detection methods and apparatus, to detect a connection mode between a radio frequency channel and an antenna, thereby reducing difficulty in secondary onsite construction, and improving construction efficiency. The method includes: receiving, by a first radio frequency unit by using each of N to-be-detected radio frequency channels, signals sent by using at least one of N reference radio frequency channels of a reference radio frequency unit; and determining a connection relationship between the N to-be-detected radio frequency channels and N antennas based on the signals received by using each to-be-detected radio frequency channel.
