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 18300696 titled 'TRANSMISSION (TX) POWER VARIATION MITIGATION FOR RECEIVED STRENGTH OF SIGNAL INDICATOR (RSSI) BASED LOCATION DETERMINATION
The abstract of this patent application discusses a method for mitigating transmission power variation to improve the accuracy of determining the location of a station based on Received Strength of Signal Indicator (RSSI) data received from multiple Access Points (APs).
- RSSI data from APs is used to determine the location of a station, with the data including RSSI values from Block Acknowledgement (BA) packets, Starting Sequence Numbers (SSN), and bitmaps.
- APs are clustered based on the combination of SSN and bitmap, with APs sharing the same combination clustered together.
- Probable locations of the station are determined within each cluster based on RSSI values received from the APs in that cluster.
- The final location of the station is determined by merging the probable locations from all clusters.
Potential Applications: - Indoor positioning systems - Asset tracking in warehouses or manufacturing facilities - Location-based services in smart buildings
Problems Solved: - Inaccuracies in determining the location of a station based on RSSI data - Variations in transmission power affecting location accuracy
Benefits: - Improved accuracy in determining station location - Enhanced performance of location-based services - Better asset tracking capabilities
Commercial Applications: Title: Enhanced Indoor Positioning System for Smart Buildings This technology can be utilized in smart buildings for precise location tracking of assets, employees, and visitors. It can enhance security measures, optimize resource allocation, and improve overall operational efficiency.
Questions about the technology: 1. How does this technology compare to other indoor positioning systems on the market? 2. What are the potential challenges in implementing this technology in large-scale environments?
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.
