Circular Hopping Pattern

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

This patent describes a method and system for transmitting data in wireless communication systems that share a frequency band, such as low-power wide-area networks (LPWAN). The core idea is to split each data packet into multiple smaller sub-packets, and transmit these using a 'circular hopping pattern' derived from a basic pattern that can be shifted in time and/or frequency. This hopping pattern allows the sub-packets to be spread out across the available channels and/or time slots, reducing the chance of interference and collisions. The approach also includes efficient detection methods in the receiving base station to lower computational effort, particularly benefiting battery-powered devices.

• Wireless sensor networks in industrial IoT (Internet of Things) environments.
• Smart metering systems for utilities (electricity, water, gas).
• Asset tracking with a large number of distributed low-power nodes.
• Smart agriculture and environmental monitoring systems.
• Home and building automation using wireless sensors and controllers.
• Healthcare monitoring systems using wearable or remote sensors.
• Any application using LPWAN technologies where frequency bands are shared among many independent networks.

BenefitsContent extracted from patent full text and abstract with AI.

• Reduces the risk of collisions and interference when multiple independent wireless systems share the same frequency band.
• Enables efficient use of available frequency and time slots, increasing network capacity and robustness.
• Significantly lowers the computational workload in receiver devices (e.g., battery-powered base stations), saving energy and prolonging device life.
• Improves the reliability and security of data transmission using pseudo-random or secure shift mechanisms for hopping patterns.
• Flexible adaptation to different application needs (low latency or high robustness) through customizable hopping patterns.
• Supports large-scale deployments with many end devices due to scalable collision avoidance.
• Complies with regulatory requirements for fair and distributed spectrum usage.
