TRANSMISSION (TX) POWER VARIATION MITIGATION FOR RECEIVED STRENGTH OF SIGNAL INDICATOR (RSSI) BASED LOCATION DETERMINATION - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240349234 titled 'TRANSMISSION (TX) POWER VARIATION MITIGATION FOR RECEIVED STRENGTH OF SIGNAL INDICATOR (RSSI) BASED LOCATION DETERMINATION
Simplified Explanation: The patent application discusses a method to mitigate transmission power variation for the Received Strength of Signal Indicator (RSSI) location estimation by clustering Access Points (APs) based on Block Acknowledgement (BA) packets and determining the probable location of a station.
- RSSI data for a station is received from multiple APs.
- The RSSI data includes a RSSI value from a BA packet, a Starting Sequence Number (SSN), and a bitmap.
- APs are clustered based on the combination of SSN and bitmap.
- APs with the same combination are clustered together.
- The probable location of the station is determined in each cluster based on RSSI values.
- The final location of the station is determined by merging probable locations from all clusters.
Key Features and Innovation:
- Clustering APs based on BA packets for more accurate location estimation.
- Utilizing SSN and bitmap to group APs with similar data.
- Determining probable and final locations of a station based on RSSI values.
Potential Applications:
- Indoor positioning systems.
- Asset tracking in warehouses.
- Location-based services in smart buildings.
Problems Solved:
- Mitigating transmission power variation for accurate location estimation.
- Enhancing the reliability of RSSI-based location tracking.
Benefits:
- Improved accuracy in station location determination.
- Enhanced performance of location-based services.
- Better management of assets in indoor environments.
Commercial Applications: Potential commercial applications include:
- Retail analytics for customer tracking.
- Smart home automation for location-based services.
- Industrial IoT for asset monitoring and tracking.
Prior Art: Readers can explore prior research on RSSI-based location estimation and clustering techniques in wireless networks.
Frequently Updated Research: Stay updated on advancements in indoor positioning systems and location estimation algorithms for wireless networks.
Questions about Location Estimation: 1. How does clustering APs based on BA packets improve location estimation accuracy? 2. What are the key factors influencing the determination of a station's final location in this method?
Original Abstract Submitted
transmission (tx) power variation mitigation for received strength of signal indicator (rssi) location may be provided. rssi data for a station may be received from a plurality of access points (aps). the rssi data may include a rssi value determined from a block acknowledgement (ba) packet and a starting sequence number (ssn) and a bitmap of the ba packet. the plurality of aps may be clustered into one or more clusters based on a combination of the ssn and the bitmap. one or more aps having a same combination of the ssn and the bitmap are clustered into one cluster. a probable location of the station may be determined in each of the one or more clusters based on rssi values received from the one or more aps of each of the one or more clusters. a final location of the station may be determined based on merging probable locations from the one or more clusters.
