Wireless Outage Detection Using Census Data Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for determining wireless service outages in telecommunication systems are inefficient, relying solely on RF signal strength estimation, which fails to accurately assess coverage levels and identify service disruptions, especially when base stations fail, impacting public safety and homeland security.
Innovation Solution
The use of census data to determine coverage levels by monitoring RF signal strength at census block centroids and recomputing coverage when base stations go out of service, ensuring accurate identification and reporting of service outages to emergency services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If RF signal strength estimation is used to determine wireless service coverage, then the measurement process is simple, but the measurement precision is insufficient to accurately assess coverage levels and identify service disruptions
Solution Approach 1:
The patent introduces census data as an intermediary element to bridge the gap between simple RF signal monitoring and accurate coverage assessment. By integrating external census information about population distribution and demographics with RF signal strength data, the system achieves more precise coverage level determination without substantially increasing system complexity. The census data serves as a mediator that translates raw signal measurements into meaningful coverage assessments.
2Reliability
If base station monitoring is implemented to detect service outages, then the reliability of service detection improves, but the loss of time for outage identification increases due to inefficient processing
Solution Approach 1:
The patent applies preliminary action by pre-processing and organizing census data before it is needed for outage determination. The system pre-establishes the relationship between census blocks, base stations, and population data, so that when a base station failure occurs, the system can quickly recompute coverage levels using pre-organized data structures. This eliminates the need for time-consuming data gathering and processing during actual outage events.
Solution Approach 2:
The system implements continuous monitoring of RF signal strength and base station status, with feedback loops that automatically trigger coverage level recomputation when changes are detected. This feedback mechanism ensures reliable outage detection while minimizing response time by immediately activating the determination process only when necessary, rather than continuously computing coverage levels.
3Measurement precision
If comprehensive coverage monitoring is performed across all areas, then the measurement precision of coverage levels improves, but the use of energy for monitoring increases significantly
Solution Approach 1:
The patent implements partial action by focusing monitoring efforts only on areas where coverage determination is necessary. Instead of continuously monitoring all geographic areas uniformly, the system uses census data to identify populated census blocks and concentrates monitoring resources on those areas. This approach achieves accurate coverage assessment in relevant areas while significantly reducing energy consumption compared to comprehensive universal monitoring.

AI summary
Methods and systems for determining an outage of the wireless communication services in an area are discussed herein. The area may indicate a geographic area defined by at least one of a city boundary, a census tract, a county boundary, or a state boundary. A method includes monitoring signals from a plurality of nodes that provide services to an area; determining, based at least in part on the signals, that at least one of the plurality of nodes is out of service; determining, based at least in part on census data of the area, a coverage level of the area, the coverage level indicating the coverage of services provided by the plurality of nodes in service; determining that the coverage level is less than a coverage threshold; and transmitting an outage notification to an emergency service provider.
