Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless mobile communication networks face challenges in providing sufficient bandwidth, capacity, and coverage, especially in densely populated areas due to the limitations of omnidirectional and directional antennas, which lead to signal interference and congestion.
Innovation Solution
Implementing a radio frequency (RF) phased array communication network with multiple access nodes, each equipped with phased array antennas that receive and transmit RF modulated data packets, allowing for high bandwidth and data rate communications by maintaining payload data in RF modulated format and dynamically routing signals to reduce congestion and interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If omnidirectional antennas are deployed to provide coverage in all directions, then coverage area is improved, but signal interference and congestion increase in densely populated areas
Solution Approach 1:
The patent applies local quality by transitioning from omnidirectional antennas that radiate uniformly in all directions to phased array antennas that concentrate RF energy in specific directional beams. Each antenna element can be independently controlled to create focused radiation patterns, providing coverage only where needed rather than uniformly in all directions, thus reducing interference in densely populated areas while maintaining adequate coverage.
Solution Approach 2:
The patent implements dynamics through electronic beam steering capability of phased array antennas. The direction of RF beams can be dynamically adjusted by changing the phase and amplitude of signals across array elements without physically moving the antenna structure. This allows the system to adaptively redirect beams to serve moving users and dynamically manage interference patterns in real-time.
2Reliability
If directional antennas are used to reduce signal interference, then signal quality is improved, but coverage area and network capacity are limited
Solution Approach 1:
The patent applies segmentation by dividing the antenna system into multiple independent elements arranged in arrays. Each element can be individually controlled to create separate directional beams, allowing the system to cover multiple directions simultaneously while maintaining the signal quality benefits of directional focusing. This overcomes the limitation of single directional antennas by creating a multi-beam system.
Solution Approach 2:
The patent implements universality by designing phased array antennas that can perform multiple functions: providing directional coverage, reducing interference, supporting multiple simultaneous users, and adapting to different service requirements. The same antenna structure can serve both as a directional antenna for quality and as a multi-beam system for expanded coverage and capacity.
3Productivity
If more cell sites are deployed to increase network capacity, then bandwidth and data rate are improved, but infrastructure complexity and deployment cost increase
Solution Approach 1:
The patent applies merging by combining multiple antenna elements into integrated phased array units that can be deployed at existing cell sites rather than requiring separate installations for each antenna. The patent also merges multiple functions (directional control, beam steering, interference management) into a single antenna system, reducing the number of separate infrastructure components needed.
Solution Approach 2:
The patent implements parameter changes by utilizing the electronic controllability of phased array antennas to dynamically adjust beam direction, width, and power distribution. This allows existing infrastructure to adapt its parameters to serve more users and provide higher capacity without adding physical infrastructure, effectively increasing network capacity through parameter optimization rather than expansion.
4Productivity
If RF modulated data packets are transmitted through multiple access nodes, then network capacity and bandwidth are improved, but transmission delay increases
Solution Approach 1:
The patent applies preliminary action by pre-calculating and establishing optimal routing paths for RF modulated data packets through the network. The system proactively manages packet routing to minimize hops and transmission delays while maintaining network capacity benefits, rather than making routing decisions that may increase delay.
Solution Approach 2:
The patent implements mechanics substitution by replacing traditional demodulation and processing of RF signals at each access node with direct RF-to-RF transmission through the network. By maintaining signals in RF modulated format throughout the network rather than converting to baseband at each node, the system eliminates processing delays while still benefiting from multi-node routing capacity.
