Multifunctional Base Station Antenna Control Unit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current mobile communication base station antennas face increased costs, installation space, and weight issues due to the need for multiple devices (RET, RAS, and RAB) connected via AISG cables, leading to complex communication procedures, especially in dual, triple, and quad-band setups.
Innovation Solution
The implementation of a multifunctional device that integrates RET, RAS, and RAB control using a single unit, connected via AISG cables, reduces the number of devices and cables required, simplifying control and installation by using a single multifunctional device for all functions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple devices (RET, RAS, RAB) are installed separately in the antenna, then each device can perform its specific control function, but the installation cost, space requirements, and weight increase
Solution Approach 1:
The patent combines multiple control devices (RET, RAS, RAB) into a single integrated control unit that can perform all three control functions. This merging approach reduces the total number of separate devices installed in the antenna, thereby decreasing installation cost, space requirements, and overall weight while maintaining full control functionality.
Solution Approach 2:
The control unit is designed with multi-functionality to perform RET (Remote Electrical Tilt), RAS (Remote Azimuth Steering), and RAB (Remote Azimuth Beam-width) control operations. This universal design allows a single device to replace multiple specialized devices, achieving weight reduction without sacrificing adaptability or control capabilities.
2Adaptability or versatility
If multiple devices (RET, RAS, RAB) are installed separately in the antenna, then each device can perform its specific control function, but the installation space and complexity increase
Solution Approach 1:
The patent integrates multiple control functions into a single control unit, reducing the number of separate devices and AISG cables required. This consolidation simplifies the overall system architecture, reduces installation complexity, and decreases the number of connection points while maintaining the ability to perform RET, RAS, and RAB control operations.
3Adaptability or versatility
If multiple devices (RET, RAS, RAB) are installed separately in the antenna, then each device can perform its specific control function, but the installation cost increases
Solution Approach 1:
The patent consolidates multiple control devices into a single integrated unit, reducing the total bill of materials and installation labor required. This merging approach decreases installation cost by reducing the number of devices to be mounted, cables to be routed and connected, and configuration steps required, while maintaining full control functionality.
