NAN Communication Schedule Adjustment for Multi-Band Coverage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems, particularly in neighbor awareness networking (NAN), face challenges in efficiently managing data paths across multiple frequency bands with different coverage areas, leading to suboptimal performance and mobility issues due to the need for frequent band switching based on device distance and environmental changes.
Innovation Solution
An electronic device is configured with a processor to establish a schedule for data communication using multiple frequency bands, adjusting time intervals based on traffic monitoring to optimize performance and mobility by dynamically allocating time slots between bands with different coverage areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the 6 GHz band is used for communication, then communication performance and signal transmission quality are improved, but coverage area becomes narrower
Solution Approach 1:
The patent combines multiple frequency bands (5 GHz and 6 GHz) into a unified communication system that can operate across both bands. The electronic device maintains simultaneous capability to use both frequency bands, merging their advantages: the 6 GHz band provides high-speed data transmission with clean channel state, while the 5 GHz band provides broader coverage area, achieving both high performance and extensive coverage
Solution Approach 2:
The patent implements dynamic frequency band selection and time interval adjustment mechanisms. The device continuously monitors communication conditions including distance to external devices and channel state, then dynamically adjusts which frequency band to use and how much time to allocate to each band. This dynamic adaptation allows the system to optimize between coverage area and signal quality based on real-time conditions
2Reliability
If frequency band switching is performed frequently based on device distance and environment changes, then communication performance is optimized, but system complexity and mobility issues increase
Solution Approach 1:
The patent establishes predetermined schedules with time intervals for different frequency bands in advance. Instead of making complex real-time decisions about when to switch bands, the device pre-configures time intervals for 5 GHz and 6 GHz band usage based on expected communication scenarios. This preliminary scheduling simplifies the system operation while maintaining the ability to adapt to different conditions
Solution Approach 2:
The patent implements a feedback mechanism where the device monitors communication conditions (distance to external devices, channel state, traffic patterns) and uses this feedback to adjust the time intervals allocated to different frequency bands. The system continuously receives feedback about communication quality and device positions, then adjusts the schedule accordingly, optimizing performance without requiring complex manual intervention
3Reliability
If time intervals for multiple frequency bands are dynamically adjusted based on traffic monitoring, then data transmission reliability is improved, but scheduling complexity increases
Solution Approach 1:
The patent implements self-service mechanisms where the communication system automatically monitors its own traffic patterns and performance metrics, then autonomously adjusts the time intervals for different frequency bands without external intervention. The device monitors its own communication conditions, detects when performance degradation occurs, and automatically reconfigures the schedule to maintain optimal performance, reducing the need for complex external scheduling management
