Embodiment Construction

[0019] The specific implementation manners of the present invention will be described in detail below with reference to the accompanying drawings.

[0020] The present invention adopts the electronically adjustable antenna remote control system, and its simple hardware system includes electronically adjustable antenna, electrically adjustable antenna control device (such as motor) and AISG cable; the complex hardware system also includes electronically adjustable antenna control device and bias T-head (Bias Tee) and other components. Among them, the simple hardware system has less equipment and can achieve the purpose of remote control. It overcomes the modem (Modem) method that must be configured with a bias T-shaped head in the conventional system. In addition, the remote ESC hardware system adopts a unique power supply method, that is, the 6-pin of the AISG interface adopts a typical 28V power supply, which can work in the voltage range of 10-30V, and is compatible with th...

Abstract

The invention provides an inclination angle remote control system of an electric tuning antenna, which comprises at least one electric tuning antenna positioned on the tower top side with an adjustable inclination angle; at least one electric tuning antenna control device for controlling and adjusting the inclination angle of the electric tuning antenna; and an electric tuning control module for communicating with the electric tuning antenna control device for controlling the electric tuning antenna control device and managing the electric tuning antenna, wherein the electric tuning antenna is connected with the electric tuning antenna control device through an AISG cable; and the AISG cable supplies power to the electric tuning antenna and a tower-top amplifier through six pins. The invention can achieve improved adjusting accuracy, simpler maintenance and more flexible networking, and meet the requirement of different application occasions, thus optimizing high-quality network, reducing the operation and the maintenance cost and improving the benefits.

Description

technical field [0001] The invention relates to the field of communication, in particular to a remote control system for the downtilt angle of an electric adjustable antenna. Background technique [0002] With the increasing demand for mobile communication systems and the increasingly fierce competition in the 3G market, domestic and foreign operators have higher and higher requirements for network quality, especially for densely populated urban areas and high-rise areas, which require large antenna downtilt angles and cell coverage. It is difficult for general mechanical antennas to meet these requirements, and only electronically adjustable antennas can meet the requirements. Because the electric adjustable antenna can make the vertical directivity diagram of the antenna downtilt by changing the phase of the collinear array antenna oscillator, changing the amplitude of the vertical component and the horizontal component, and changing the field strength of the composite com...
