Solution Overview

Problem

Conventional locationing devices/systems struggle to reliably detect advertisement packets from beacon devices due to the short duration of advertisement periods and strict timing/channel requirements, leading to inefficient and unreliable locationing services.

Innovation Solution

A transceiver device with multiple radio transceivers that synchronizes to scan across multiple advertisement channels in a rotating manner, ensuring that at least one transceiver is scanning each channel during a scan period, thereby enhancing data capture robustness.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a single radio transceiver scans advertisement channels sequentially, then the device complexity is low, but the data capture robustness deteriorates due to channel mismatches during short advertisement periods

Engineering Contradiction:
Improvedata capture robustnessVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent divides the scanning function into multiple independent radio transceivers, where each transceiver is assigned to scan specific advertisement channels during different time periods. This segmentation allows parallel scanning of multiple channels simultaneously, ensuring that at least one transceiver is always tuned to the correct channel when advertisement packets are transmitted, thereby improving data capture robustness while distributing the complexity across multiple components.

Inventive Principle:
Principle #1Segmentation

2Speed

If the advertisement period duration is kept short, then the system responsiveness improves, but the probability of successful packet reception deteriorates due to strict timing requirements

Engineering Contradiction:
Improvesystem responsivenessVSAvoidpacket reception reliability
Core Design Contradiction:
SpeedVSReliability

Solution Approach 1:

The patent implements preliminary synchronization actions where transceiver devices establish synchronized scanning schedules before advertisement packets are transmitted. The coordinator device configures each transceiver with predetermined time periods and channel assignments, ensuring that transceivers are pre-positioned to scan the correct channels at the correct times. This preliminary coordination enables the system to maintain short advertisement periods for responsiveness while guaranteeing reliable packet reception through advance timing arrangement.

Inventive Principle:
Principle #10Preliminary action

3Productivity

If multiple transceivers scan different channels simultaneously, then the data capture efficiency improves, but the synchronization complexity increases

Engineering Contradiction:
Improvedata capture efficiencyVSAvoidsynchronization complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent incorporates feedback mechanisms where the coordinator device monitors the scanning status and performance of each transceiver, and adjusts synchronization parameters accordingly. Transceivers report their channel scanning results and timing status back to the coordinator, which then optimizes the time period assignments and channel allocations to maintain efficient parallel scanning while managing synchronization complexity through continuous feedback and adjustment.

Inventive Principle:
Principle #23Feedback

AI summary

Radio transceiver devices and methods are disclosed herein. An example transceiver device includes at least one processor, a plurality of radio transceivers, and a memory. The memory may store instructions that, when executed by the at least one processor, cause the transceiver device to cause the plurality of radio transceivers to scan over each of a plurality of advertisement channels during a first period; and during a second period of the scan period, cause the plurality of radio transceivers to scan over each of the plurality of advertisement channels. The instruction may further cause the transceiver device to receive a beacon data packet including beacon information that is associated with a beacon device disposed proximate to the transceiver device, and wherein the beacon data packet includes beacon information captured during the first period and the second period.
