Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current Bluetooth Low Energy (BLE) technology faces limitations in data transmission across different scenarios due to its restricted frequency hopping capabilities within the 2400Mhz~2480Mhz band, which cannot meet diverse application requirements and is vulnerable to interference and security breaches during Bluetooth pairing.
Innovation Solution
A data transmission method that supports multiple working modes, including standard and non-standard modes, allowing frequency hopping among standard and extended channels, using a first chip and a second chip to switch between modes based on trigger conditions for enhanced compatibility, security, and efficiency, thereby expanding the scope of application and improving data transmission stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If Bluetooth Low Energy uses standard frequency hopping among 40 channels in the 2400Mhz~2480Mhz band, then compatibility with existing Bluetooth protocol is maintained, but data transmission efficiency and stability deteriorate in high-density networks and under interference
Solution Approach 1:
The frequency band is segmented into standard channels (40 channels in 2400Mhz~2480Mhz) and extended channels (additional channels beyond the standard band). The system can selectively use standard channels for compatibility or extended channels for improved performance, dividing the communication resource into distinct segments that serve different purposes.
Solution Approach 2:
The patent extends the frequency hopping domain by adding extended channels beyond the standard 40-channel Bluetooth band. This dimensional expansion from the conventional frequency domain to a broader spectrum domain provides additional pathways for data transmission, reducing congestion and interference in the original channel space.
2Adaptability or versatility
If Bluetooth Low Energy uses standard frequency hopping among 40 channels, then protocol compatibility is maintained, but vulnerability to interference and security breaches during pairing increases
Solution Approach 1:
Extended channels serve as an intermediary frequency domain for secure pairing operations. By conducting pairing negotiations and authentication on extended channels rather than standard Bluetooth channels, the system creates a separate, less monitored communication path that reduces exposure to eavesdropping and interference while maintaining protocol compatibility on standard channels for data transmission.
3Adaptability or versatility
If frequency hopping is limited to 40 standard channels, then Bluetooth protocol compliance is ensured, but channel load increases in high-density networks
Solution Approach 1:
The channel space is segmented into standard channels (for protocol compliance and general use) and extended channels (for additional capacity). This segmentation allows the system to distribute traffic across both segments, preventing any single segment from becoming overloaded while maintaining compliance with Bluetooth standards on the standard channel portion.
Solution Approach 2:
The patent adds extended channels as an additional dimensional resource beyond the conventional 40-channel Bluetooth spectrum. This expansion provides more available pathways for data transmission, effectively increasing the channel capacity and reducing load density on any individual channel in high-density network scenarios.
4Ease of operation
If only standard Bluetooth channels are used, then device compatibility is maintained, but adaptability to different transmission scenarios is reduced
Solution Approach 1:
The communication system is designed with multi-functionality to operate in multiple modes: standard Bluetooth mode for compatibility, extended channel mode for enhanced performance, and hybrid mode combining both. This universal design allows the same device to adapt to different transmission scenarios by selecting the appropriate operating mode, maintaining ease of operation across diverse applications.
Solution Approach 2:
The system dynamically selects between standard channels and extended channels based on transmission requirements, network conditions, and scenario demands. This dynamic adaptability allows the communication system to optimize performance for different scenarios while maintaining backward compatibility, transitioning flexibly between operational modes as needed.
