RF Data Collection Time Synchronization for Disparate Locations
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for coordinating uplink and downlink RF transmission measurements require manual alignment of data collected at disparate locations without a shared network or data connection, leading to inefficient and limited data coordination.
Innovation Solution
Implementing RF data collection devices with synchronized local times using a common time source, such as a network time server or local broadcast signal, to enable coordinated data recording and alignment without relying on shared networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If manual data collection methods are used at disparate locations without shared network, then device independence and operational flexibility are improved, but data coordination precision and time alignment accuracy deteriorate
Solution Approach 1:
The patent introduces an intermediary synchronization mechanism that allows independent devices to achieve time coordination. Each device independently collects RF data while using a common synchronization signal (such as a broadcast time signal or network time protocol) as an intermediary to align timestamps across devices without requiring direct network connectivity between them.
Solution Approach 2:
The patent applies preliminary synchronization actions where devices pre-establish time alignment using synchronization signals before data collection begins. This preliminary action ensures that all devices start with synchronized clocks and continue to maintain time alignment throughout the measurement period, enabling accurate cross-device data coordination.
2Productivity
If data is recorded for extended periods to enable timestamp matching, then data coordination capability is improved, but operational complexity and time loss increase
Solution Approach 1:
The patent implements feedback mechanisms where devices continuously monitor and adjust their timestamps based on synchronization signals. This feedback loop allows devices to maintain accurate time alignment in real-time without requiring extended recording periods, as the synchronization information is continuously updated and fed back to each device.
Solution Approach 2:
The patent ensures continuity of useful action by maintaining active time synchronization throughout the entire data collection period. Rather than recording data for extended periods and then attempting to match timestamps, the system continuously synchronizes clocks and timestamps in real-time, eliminating the need for post-processing time alignment.
3Adaptability or versatility
If independent RF scanning equipment is deployed at multiple locations, then measurement coverage and system versatility are improved, but device complexity and coordination difficulty increase
Solution Approach 1:
The patent applies universality by designing a common synchronization interface that can be used by multiple independent RF scanning devices at different locations. Each device uses the same synchronization protocol and signal format, allowing them to coordinate their measurements despite being physically separated and operating independently.
Solution Approach 2:
The patent segments the synchronization function from the data collection function. Each independent RF scanning device maintains its own data collection operations while separately utilizing the synchronization signal. This segmentation allows devices to operate independently for data gathering while sharing a common time reference, reducing overall system complexity.

AI summary
Systems and methods for time coordinating a plurality of RF data collection devices at disparate locations are provided. Such systems and methods can include synchronizing a local time of a first RF data collection device to an initial value of a common time source, generating a timestamp log file documenting a propensity of the local time to deviate from the common time source, collecting and recording a first plurality of RF data from an RF network, and using the timestamp log file to normalize the first plurality of RF data for comparison with a second plurality RF data recorded by a second RF data collection device.
