Study Notes
Real-Time Location Systems (RTLS)
- Types of RTLS: Precision-based and Proximity-based.
- Precision-based RTLS provides accurate location tracking (over 300 meters) using technologies like Ultra-Wideband (UWB).
- Proximity-based RTLS tracks within a zone (a few square feet), utilizing cheaper technologies such as BLE Bluetooth beacons and Wi-Fi, with a range up to 20 meters.
- Applications include tracking medical equipment, staff location, and asset management.
GPS Tracking Software
- Utilizes Internet of Things (IoT) and Global Positioning System (GPS) to track locations in real-time.
- Gathers data from GPS sensors on objects or individuals and sends it to a central server for processing and visualization.
- Common applications include logistics, fleet management, crime detection, and personal safety.
- GPS receivers capture signals from GPS satellites, still a reliable solution for payment systems.
IoT Encryption Algorithms
- RSA Algorithm is a widely used asymmetric encryption method ensuring secure message transmission without sharing the code.
