Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cell towers experience interference from adjacent electromagnetic radiation (EMR) sources, leading to potential disruptions in communications, which existing methods like filter deployment are costly and time-consuming to address.
Innovation Solution
A method and system where a base station determines the azimuth and distance of EMR sources and temporarily ceases uplink and downlink transmissions when the EMR source is directed towards a sector, using predictable patterns to minimize interference without the need for additional equipment.

Engineering Contradiction Analysis
1Reliability
If filter deployment is used to address EMR interference, then interference protection is improved, but deployment time and maintenance costs increase
Solution Approach 1:
The base station pre-computes azimuths of sectors and identifies potential EMR interference sources before actual interference occurs. By determining which sectors are most susceptible to interference in advance and establishing cessation schedules based on predictable EMR patterns, the system prepares mitigation strategies proactively rather than reactively, reducing deployment time when interference actually occurs
Solution Approach 2:
The base station autonomously monitors signal values, determines interference conditions, computes cessation time periods, and executes transmission suspensions without requiring external filter deployment or manual intervention. The system serves itself by using its own computational resources and existing monitoring capabilities to identify and mitigate interference, eliminating the need for external maintenance personnel and filter installation
2Reliability
If filter deployment is used to address EMR interference, then interference protection is improved, but maintenance costs increase
Solution Approach 1:
The base station uses its existing monitoring and computational capabilities to autonomously detect EMR interference, determine affected sectors, compute cessation schedules, and execute transmission suspensions. This self-service approach eliminates the need for expensive filter hardware and the maintenance personnel required to install and service those filters, reducing ongoing maintenance costs while maintaining interference protection
Solution Approach 2:
The patent replaces the mechanical/physical filter deployment approach with a software-based computational method. Instead of physically installing and maintaining filter hardware, the base station uses signal monitoring, azimuth computation, and automated transmission control to mitigate interference, substituting electronic/software solutions for mechanical systems and thereby reducing maintenance requirements
3Reliability
If transmissions are ceased during EMR emission periods, then interference is reduced, but communication continuity is affected
Solution Approach 1:
The base station computes specific time periods when EMR sources are predicted to emit radiation toward affected sectors and schedules transmission cessations only during those periodic intervals. By aligning transmission suspensions with the periodic emission patterns of EMR sources rather than implementing continuous suspensions, the system minimizes the duration of communication interruptions while still protecting against interference during critical emission periods
Solution Approach 2:
The base station dynamically adjusts transmission cessation schedules based on computed EMR emission patterns, sector azimuths, and distance calculations. Rather than using fixed or continuous suspension, the system dynamically determines when cessations are necessary based on real-time monitoring data and predictive computations, optimizing the balance between interference reduction and communication continuity

AI summary
Methods and systems are provided for reducing the potential of interference between a cell tower and a neighboring EMR source. At a base station, such as an eNodeB, it is determined that a sector of the cell tower has the potential for interference with the EMR source based on, for instance, monitoring of network parameters, a computation of the sector's azimuth, and a distance between the sector and the EMR source. Time intervals are computed corresponding to when the EMR source emits EMR in a direction of the sector of the base station, Uplink and downlink transmissions to and from the sector of the cell tower are ceased during the computed time intervals.
