Plug-and-play power adjustment: The best choice for the 4G age Antenna System

With the development of global 4G networks in full swing in recent years, how to simplify the deployment of remote adjustment antennas and improve their reliability has become a new concern of operators for the antenna feed system. Due to its inherent requirements for on-site access, low operation and maintenance efficiency, and affected antenna radiation performance, the method of mechanical tilting optimization antennas has gradually withdrawn from the historical stage, without the need for on-site and easy-to-maintain remote Electrical adjustment antennas, the mainstream choice of global operators, the base station antenna system began to enter the "all-electric adjustment era ".

Traditional remote adjustment antennas are deployed in a complex and have low reliability.

Traditional remote adjustment antennas are composed of antennas, remote control units (RCU), and control cables. They are installed on site during site construction and configured and tested in the IDC. Overseas, traditional remote adjustment antennas are widely used in 3G network construction due to remote adjustment of the power-off angle. However, with the large-scale use of multi-frequency antennas, the installation and deployment of remote adjustment systems are complex and the problems of low reliability are also becoming increasingly prominent:

Complex and time-consuming installation: You need to install an external RCU and control cable on the site. Taking one three-frequency antenna as an example, three RCUs and three control cables need to be installed to complete the antenna installation for one site for at least two hours;

The commissioning process is cumbersome and inefficient: You need to complete a series of operations such as RCU scanning, data loading, and calibration before setting the antenna power-off angle. manual operation steps are many, which are prone to errors and the commissioning efficiency is low;

The system is complex and the reliability is low for a long time: RCU is used externally for antennas and control cable connections. On the one hand, it puts forward high requirements on the construction quality of the Electrical adjustment system, once the installation quality problem occurs, it will directly lead to the electrical Commissioning System failure. On the other hand, RCU corrosion, RCU structural part force shedding, and other problems may also occur during long-term use.

Out-of-the-box power adjustment antenna is efficient and reliable

In the 4G era, wireless mobile networks present a Multi-standard, multi-frequency hybrid networking trend, improving deployment efficiency and creating high-quality networks are shared by global operators. In order to solve the complicated deployment and low reliability problems of traditional remote adjustment antennas and better meet the current network construction needs, the adjustment antenna introduces an innovative "plug-and-play" solution, this solution has two features: Simplified installation and commissioning, and high reliability:

Simplified installation and commissioning: the antenna has a built-in remote Electrical adjustment module. you can install a control cable on the site. Taking a three-frequency antenna as an example, the plug-and-play Electrical adjustment antenna only needs to install a control cable to connect the Electrical adjustment antenna to the base station RF module. The installation time of one station can be reduced by about 40 minutes. At the same time, the plug-and-play remote Electrical adjustment antenna can complete configuration data loading and offline tilt calibration before leaving the factory, so as to achieve load-free and calibration-free when starting the station, it saves about 20 minutes of commissioning time for each base station, greatly improving the deployment efficiency of the Electrical adjustment antenna.

High reliability: with the built-in design of the remote Electrical adjustment module, a single cable can control the Electrical adjustment antenna, greatly reducing the number of connection points, the design enhances the remote Electrical adjustment protection capability, avoids the impact of construction quality, and improves the reliability of the remote Electrical adjustment antenna.

The "out-of-the-box" Electrical adjustment antenna is simplified, and the deployment efficiency and reliability are both improved, effectively solving the complicated deployment and low reliability of traditional Electrical adjustment antennas, it has become the best choice for network construction in the 4G era of operators.
