Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless radio network installations involving remote radio units (RRUs) and antennas are complex, time-consuming, and prone to errors due to the need for multiple jumper cables and RF signal conditioning units, which are affected by outdoor temperature and humidity conditions, leading to potential interconnect quality issues and performance problems.
Innovation Solution
A modular telecommunications system comprising a mounting frame with integrated RRU and RF signal conditioning units, covered by a single module with perforated regions for cooling, allowing for pre-installation testing, simplified installation, and enhanced reliability, featuring a frame with adapter plates for easy component replacement and reduced tower leasing costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If separate RRUs and antennas are mounted on the tower with multiple jumper cables and RF signal conditioning units, then the system can be deployed with existing component standards, but the installation becomes complex and time-consuming
Solution Approach 1:
The patent combines the RRU, RF signal conditioning units, and antenna mounting structure into a single integrated cell site module. This merging eliminates the need for multiple separate components and jumper cables, directly reducing installation complexity while maintaining adaptability through standardized external interfaces.
Solution Approach 2:
The integrated module serves multiple functions simultaneously: it houses the RRU for radio frequency processing, includes RF signal conditioning units for signal optimization, provides mounting structures for antennas, and incorporates cooling systems. This multi-functionality reduces the number of separate installations needed while maintaining compatibility with existing component standards.
2Adaptability or versatility
If multiple jumper cables and RF signal conditioning units are installed on site, then the system can be configured flexibly, but the installation time increases to approximately 12-15 hours per site
Solution Approach 1:
The RRU, RF signal conditioning units, and interconnections are pre-assembled and pre-tested as a complete module at the manufacturing facility. This preliminary action allows the module to be deployed as a single unit, reducing on-site installation time from 12-15 hours to a fraction of that time, while maintaining system configurability through standardized interfaces.
Solution Approach 2:
By merging all installation components into a single pre-assembled module, the patent eliminates the need for time-consuming on-site cable routing, connection, and configuration tasks. The module maintains adaptability through standardized external interfaces that allow flexible system integration.
3Ease of operation
If installations are performed outdoors in variable temperature and humidity conditions, then the system can be deployed at remote locations, but interconnect quality and overall system performance are adversely affected
Solution Approach 1:
All interconnections and configurations are completed in a controlled manufacturing environment before deployment. This preliminary action ensures high interconnect quality by avoiding exposure to adverse outdoor conditions during installation, while the completed module retains full deployment capability at remote locations.
Solution Approach 2:
The integrated module design protects internal components and interconnections from environmental factors by enclosing them within a sealed structure. This beforehand protection prevents temperature and humidity from degrading interconnect quality, while still allowing the system to operate in remote outdoor locations.
4Adaptability or versatility
If separate mounting kits and hardware are used for each component, then the system can accommodate different component variations, but the installation involves substantial complexity and multiple mounting procedures
Solution Approach 1:
The patent consolidates multiple separate mounting kits and hardware sets into a single integrated mounting structure that holds all components (RRU, RF signal conditioning units, antennas). This merging simplifies the mounting process to a single installation procedure while maintaining adaptability through adjustable mounting points and standardized interfaces.
