Telegram Splitting-Based Localization

Simple SummaryContent extracted from patent full text and abstract with AI.

This patent discloses a method and system for improved localization (position determination) in wireless communication networks using 'telegram splitting'. The invention involves dividing a data packet into several sub-data packets (or 'hops'), each transmitted on different carrier frequencies and potentially at different times. By analyzing the phase difference between these received hops, caused both by frequency differences and path delays, precise distance differences (and thus locations) between transmitters and receivers can be calculated. This innovation makes localization more accurate and robust, especially in environments with many sensor nodes (like telemetry networks).

Use CasesContent extracted from patent full text and abstract with AI.

• Asset tracking in logistics and supply chains, including real-time location of goods in warehouses or during transport.
• Smart metering solutions, such as automatic utility meter reading with location capability for gas, water, or electricity meters.
• Industrial IoT (Internet of Things) sensor networks for monitoring and localizing equipment or components in large facilities.
• Localization in low-power wide-area (LPWA) networks where devices must be tracked over long distances with minimal energy consumption.
• Indoor positioning systems for navigation and resource management within buildings or campuses.
• Smart city deployments for locating and managing distributed infrastructure or sensors (e.g., streetlights, environmental sensors).
• Emergency response scenarios where precise location of devices (e.g., wearable medical sensors, alarms) is critical.

BenefitsContent extracted from patent full text and abstract with AI.

• Enables highly accurate and robust localization even in challenging RF environments with multipath interference.
• Reduces ambiguity and increases resilience to noise or signal collisions by using multiple frequencies and timeslots for packet transmission.
• Optimized for low-power sensor nodes, making it suitable for battery-powered or energy-harvesting devices.
• Adaptable localization precision—energy and frequency distribution can be tuned for either higher accuracy or better multipath detection, as needed.
• No stringent requirements for tight time synchronization between the sender and receiver, simplifying deployment in distributed networks.
• Can be implemented in both hardware and software, and integrated into existing wireless communication systems.
• Supports scalable deployment in dense sensor networks, important for modern IoT and smart city applications.

Patent Abstract

Embodiments relate to a data receiver with a device for receiving sub-data packets, a device for ascertaining a phase difference, and a device for ascertaining a distance difference. The device for receiving sub-data packets is designed to receive at least two sub-data packets from a data transmitter and to combine the at least two sub-data packets in order to obtain a data packet which is transmitted in a divided state into the at least two sub-data packets by the data transmitter. Each of the at least two sub-data packets is shorter than the data packet. The device for receiving sub-data packets is designed to receive the at least two sub-data packets on at least two different carrier frequencies. The device for ascertaining a phase difference is designed to ascertain a phase difference between the at least two sub-data packets, said phase difference being caused by the at least two different carrier frequencies and the path delay. The device for ascertaining a distance difference between the data receiver and the data transmitter is designed to ascertain the distance difference on the basis of the ascertained phase difference between the at least two sub-data packets.
