Parallel Wireless Channel Scanning via Dual-Transceiver Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication devices consume excessive power and experience interruptions during channel scanning operations, as they typically scan channels sequentially, which prolongs the scanning process and disrupts normal communication traffic.
Innovation Solution
Implementing a parallel scanning method that allows simultaneous scanning of multiple channels within the same or different frequency bands using dual-transceiver devices, reducing scan time and power consumption by enabling transceivers to be powered down or placed in an idle mode after scanning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If sequential scanning is used, then device complexity is reduced, but scanning time increases and power consumption increases
Solution Approach 1:
The patent divides the scanning function into multiple independent transceivers, where each transceiver is responsible for scanning specific channels. This segmentation allows parallel scanning operations to occur simultaneously across different channels, reducing total scanning time while keeping each individual transceiver relatively simple in design.
Solution Approach 2:
The patent transitions from sequential scanning (one-dimensional time progression) to parallel scanning by adding the dimension of multiple simultaneous transceivers operating on different channels. This dimensional change enables multiple scanning operations to occur concurrently rather than sequentially.
2Device complexity
If sequential scanning is used, then device complexity is reduced, but power consumption increases
Solution Approach 1:
By segmenting the scanning function across multiple transceivers, the system can power down individual transceivers after they complete their channel scanning tasks. This segmentation enables selective power management where only necessary transceivers remain active, reducing overall power consumption while maintaining relatively simple device architecture.
Solution Approach 2:
The patent implements a power management strategy where transceivers are discarded (powered down) after completing their scanning function. This allows the system to recover energy by placing unused transceivers in low-power states, reducing overall power consumption while maintaining the ability to reactivate them if needed.
3Loss of time
If parallel scanning is implemented, then scanning time is reduced, but device complexity increases
Solution Approach 1:
The patent uses segmentation to divide the parallel scanning function into multiple independent transceiver units. Each transceiver handles specific channel scanning independently, which simplifies the control logic for each unit while achieving overall parallel scanning. This segmentation approach reduces scanning time without requiring a single complex centralized controller.
4Use of energy by moving object
If parallel scanning is implemented, then power consumption is reduced, but device complexity increases
Solution Approach 1:
By segmenting the scanning function across multiple transceivers, the system achieves better power management. Each transceiver can be independently powered down after completion, allowing the system to reduce overall power consumption. The segmentation approach makes it easier to manage power states compared to a single complex transceiver that must continuously operate all channels.

AI summary
Methods, systems, and apparatus for parallel scanning of channels in communication networks are described herein. A parallel scanning device performs a scanning operation that includes parallel (i.e., simultaneous) scanning of channels that are in a common frequency band or in different frequency bands. The parallel scanning of channels results in a reduction of scan time, which reduces power consumption. Furthermore, a scanning operation may undesirably interrupt and/or delay normal communication traffic to and from the parallel scanning device, and the comparatively shorter scan time resulting from the parallel scanning operation can reduce such interruption and/or delay.
