Station Operation Mode Control via Distance Threshold
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication environments, the increasing number of infrastructure stations leads to reduced transmission signal power and excessive resource wastage due to overlapping service areas and interference between adjacent stations, necessitating a method to efficiently control station operation modes and reduce resource waste.
Innovation Solution
A system that determines the operation mode of a second communication station by comparing the distance between it and a first station with a threshold distance, considering service area overlap, available power, and traffic loads, and uses an idle mode to maintain power and settings while pausing communication operations, thereby reducing resource waste and enabling rapid setup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the number of infra-stations is increased to provide high-quality wireless communication service, then communication service quality is improved, but interference between adjacent infra-stations is generated and wireless resources are excessively wasted
Solution Approach 1:
The patent implements dynamic operation mode control for infra-stations, allowing them to switch between active and idle modes based on real-time conditions. The controller determines whether adjacent infra-stations should operate actively or remain in idle state, dynamically adjusting the network configuration to prevent interference and resource waste while maintaining service quality.
2Loss of energy
If any one of the adjacent infra-stations is turned off to prevent service area overlap, then wireless resource waste is reduced, but it takes a long time for the powered-off infra-station to perform initial setup
Solution Approach 1:
The patent keeps infra-stations in an idle state rather than completely powering them off. In this idle state, the infra-stations maintain their initial environment settings and power configuration, so when they need to transition to active mode, they can do so rapidly without performing time-consuming initial setup procedures. This preliminary maintenance of operational state resolves the contradiction between resource savings and setup time.
3Area of stationary object
If all infra-stations are enabled to cover service areas, then communication coverage is improved, but interference between adjacent infra-stations occurs
Solution Approach 1:
The patent applies different operation modes to different infra-stations based on their local conditions. The controller evaluates each infra-station's service area and determines whether it should operate in active or idle mode, creating a non-uniform operational configuration across the network. This allows full geographic coverage while preventing interference in areas where infra-station service areas overlap.
