Dual Transceiver Parallel Scanning for Bluetooth Efficiency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Bluetooth devices face inefficiencies in scanning multiple channels, causing delays in data packet transfers and increased power consumption due to sequential scanning of Bluetooth classic and low energy channels, as well as potential interference from other wireless technologies in the same frequency band.
Innovation Solution
An electronic device equipped with dual wireless transceivers allows parallel scanning of Bluetooth classic and low energy channels, enabling simultaneous real-time and non-real-time data packet transfers while continuously monitoring for channel interference to avoid congested channels, thereby optimizing bandwidth and power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If sequential scanning of Bluetooth classic and low energy channels is performed, then channel scanning is completed, but scanning time is increased and data transfer delays occur
Solution Approach 1:
The patent divides the channel scanning function into two separate transceivers: one dedicated to Bluetooth classic channels and another to Bluetooth low energy channels. This segmentation allows both scanning operations to occur simultaneously rather than sequentially, reducing total scanning time and eliminating data transfer delays caused by waiting for channel scans to complete.
Solution Approach 2:
The patent combines multiple scanning functions (Bluetooth classic scanning and Bluetooth low energy scanning) into a unified dual-transceiver system that operates in parallel. By merging these previously separate operations into a coordinated simultaneous execution model, the system achieves faster overall scanning while maintaining both classic and low energy connectivity capabilities.
2Device complexity
If a single transceiver is used for both Bluetooth classic and low energy operations, then device complexity is reduced, but bandwidth efficiency decreases and interference increases
Solution Approach 1:
The patent segments the transceiver functionality by implementing two separate transceivers with distinct responsibilities: one optimized for Bluetooth classic operations and another for Bluetooth low energy operations. This segmentation prevents bandwidth conflicts and interference between the two protocols while maintaining relatively simple individual transceiver designs, as each transceiver is dedicated to a specific protocol rather than attempting to handle both.
3Use of energy by moving object
If sequential scanning is performed, then power consumption is reduced, but scanning time and data transfer delays increase
Solution Approach 1:
The patent segments the power consumption burden by distributing scanning operations across two separate transceivers. Each transceiver operates independently and continuously for its designated protocol, eliminating the need to power up a single transceiver repeatedly for sequential scanning. This results in more efficient overall power utilization despite the presence of two transceivers, as each operates at optimal efficiency for its specific protocol.

AI summary
In an example, an electronic device may include a network interface device having a first transceiver to communicate via a short-range wireless communication protocol and a second transceiver to communicate via the short-range wireless communication protocol. Further, the electronic device may include a processor connected to the network interface device. During operation, the processor may receive a request to search a first device in accordance with the short-range wireless communication protocol. Further, the processor may search a first radio frequency channel via the first transceiver to detect the first device. Furthermore, the processor may search a second radio frequency channel via the second transceiver to detect the first device. The first radio frequency channel and the second radio frequency channel may be searched in parallel.
