Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Determining the optimal geographic locations for deploying wireless radios and antennas to establish high-speed, reliable, and economical long-distance radio communication links is challenging due to the complexity of permutations of potential sites, variations in infrastructure, terrain, and RF propagation limitations, requiring a tool that can efficiently identify suitable sites to meet specific radio link performance objectives.
Innovation Solution
A microwave path search tool that analyzes radio path profiles between two locations, using incremental buffer expansions and design constraints to identify optimal radio path trails that meet latency, clearance, and infrastructure cost objectives by evaluating potential sites within a defined geographic area.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a large number of potential radio sites are considered to ensure coverage and performance options, then the quality and reliability of the radio link can be improved, but the computational complexity and time required to evaluate all permutations of sites increases significantly
Solution Approach 1:
The patent divides the buffer area into multiple segments radiating from the source location, with each segment representing a directional sector. This segmentation allows the system to evaluate sites in an organized manner across different directions, managing the complexity of large-scale site evaluation by breaking it into manageable directional segments.
Solution Approach 2:
The patent performs preliminary actions by first identifying candidate sites within each segment before evaluating complete radio path permutations. The system pre-processes site data, calculates initial path profiles, and filters sites based on basic criteria before conducting comprehensive performance analysis, thereby reducing the computational burden of evaluating all possible permutations.
2Measurement precision
If comprehensive evaluation of all site permutations is performed to identify optimal radio paths, then the precision of path selection can be improved, but the time required for analysis increases
Solution Approach 1:
The patent segments the evaluation process into distinct phases: identifying candidate sites within each segment, evaluating path profiles for those sites, and then selecting optimal paths based on performance criteria. This segmented approach maintains evaluation precision while reducing overall analysis time by processing sites in manageable groups rather than all at once.
Solution Approach 2:
The patent applies partial action by evaluating a representative subset of sites within each segment rather than exhaustively analyzing every possible site permutation. The system identifies candidate sites that meet basic criteria and focuses detailed evaluation on those most likely to yield optimal paths, achieving sufficient precision without the time cost of complete enumeration.
3Adaptability or versatility
If the buffer area for site search is expanded to include more potential locations, then the versatility of path options can be improved, but the computational burden of evaluating sites in larger areas increases
Solution Approach 1:
The patent divides the expanded buffer area into multiple directional segments radiating from the source, allowing the system to manage and evaluate sites across a large geographic area in an organized manner. Each segment handles a specific directional sector, making the evaluation of dispersed sites more efficient while maintaining comprehensive coverage of the expanded buffer area.
Solution Approach 2:
The patent introduces a directional dimension by organizing sites into segments based on their angular position relative to the source location. This dimensional organization transforms the evaluation from a two-dimensional geographic search into a structured multi-segment analysis, improving productivity by systematically processing sites across the expanded buffer area rather than treating it as a single large region.
Data Source
AI summary
A microwave path search tool for finding radio path trails between a source site at a first geographic location and a target site at a second geographic location, wherein radio paths constituting a radio path trail meet certain radio link design goals subject to certain design constraints. The tool receives information relating to the source and target sites and sites within a buffer region around the source and target sites. The tool also receives path profile computation information such as data representing the terrain and clutter in the buffer region. The tool uses this information to analyze potential radio paths and identify radio paths forming a radio link between the source and target sites that best meets the radio link design goals. The tool can also perform pre-run analysis and use incrementally increasing linear or segmented expansions of search areas within the buffer region to facilitate the radio path search.
