Standard Antenna Interface for RRH Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional wireless radio network installations involving separate remote radio heads (RRH) and antennas are complex, time-consuming, prone to errors, and result in RF losses and Passive Intermodulation (PIM) issues, limiting flexibility and increasing costs due to the need for multiple jumper cables and non-standard mounting configurations.
Innovation Solution
A Standard Antenna Interface with universal mounting structures and RF interconnection modules that allow for flexible mounting of RRHs and antennas from different suppliers, eliminating the need for jumper cables and enabling independent replacement of RRHs and antennas, thus reducing installation time and costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If separate RRH and antenna are mounted with multiple jumper cables, then RF signal transmission is achieved, but installation time increases and installation complexity increases
Solution Approach 1:
The patent combines the RRH and antenna into a single integrated unit mounted on the tower, eliminating the need for multiple jumper cables and separate mounting procedures. This integration directly reduces installation time and complexity while maintaining RF signal transmission functionality.
2Reliability
If multiple jumper cables are used to connect RRH and antenna, then RF signal transmission is achieved, but RF losses increase and PIM performance deteriorates
Solution Approach 1:
By integrating the RRH and antenna into a single unit, the patent eliminates multiple jumper cable connections that cause RF losses and Passive Intermodulation (PIM) products. The direct integration ensures better RF signal quality without energy loss through intermediate connectors.
3Ease of operation
If integrated antenna design is used, then installation simplicity is improved, but supplier flexibility is reduced and adaptability decreases
Solution Approach 1:
The patent designs a universal mounting interface that can accommodate RRH and antenna units from different suppliers. The standardized mechanical and electrical interfaces allow network operators to mix and match components from various manufacturers while maintaining installation simplicity, thus achieving both ease of operation and supplier flexibility.
4Adaptability or versatility
If separate mounting structures are used for RRH and antenna, then mounting flexibility is achieved, but installation errors increase and reliability decreases
Solution Approach 1:
The patent implements a standardized universal mounting structure with predefined mechanical and electrical interfaces. This standardization eliminates installation errors caused by custom mounting configurations while maintaining the flexibility to mount different RRH and antenna models. The consistent interface design ensures reliable connections across all installations.
5Loss of time
If integrated antenna unit is used, then installation time is reduced, but inventory costs increase and repair complexity increases
Solution Approach 1:
The patent segments the integrated unit into replaceable modular components (RRH module and antenna module) connected through standardized interfaces. This allows the antenna to be replaced independently of the RRH and vice versa, reducing inventory costs by allowing separate stocking of components and simplifying repairs by enabling targeted component replacement rather than entire unit replacement.

AI summary
An RF interconnection module includes a housing having a perimeter, a capacitive coupling, and a float gasket disposed about the perimeter of the housing. When the housing is mounted in an opening, the float gasket is positioned between the housing and the opening. The float gasket may be made of an elastomer material and may include a plurality of outwardly extending ribs for movable securing the gasket in the opening. In addition, a mount assembly includes a bracket assembly attachable to a tower-mounted equipment and at least one jumper cable having at least one ohmic connector for connecting to the tower-mounted equipment and at least one capacitive connector. The capacitive connector may comprise an RF interconnection module mounted on the bracket assembly. The bracket assembly may be adjustable to accommodate tower mounted equipment of various sizes.
