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

This patent describes a method and system for efficiently transmitting data packets of variable length in low-power wireless networks. The invention splits data into a fixed number of sub-packets, with each sub-packet's size adapting to the total amount of data. This enables efficient use of bandwidth, reduces overhead, and ensures high reliability even under varying data loads. The technique also incorporates synchronization sequences to allow for robust and adaptable data transmission and reception, especially useful in environments with many low-powered devices (such as sensor networks) where power efficiency and reliable data transfer are critical.

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

  • Wireless sensor networks where devices operate on small batteries and send variable amounts of data.
  • Industrial or environmental monitoring systems with hundreds of thousands of sensors communicating to a central station.
  • Smart home or building automation systems with numerous low-power IoT devices.
  • Telemetry systems requiring robust, interference-resistant communication with changing data payloads.
  • Remote health monitoring devices that need to send varying data efficiently and reliably.
  • Wireless metering for utilities (e.g., energy, water), where end-points have unpredictable amounts of information to report.
  • Any wireless network where minimal coordination among transmitters is possible due to power or protocol limitations.

BenefitsContent extracted from patent full text and abstract with AI.

  • Reduces communication overhead by using a constant number of sub-packets regardless of message length.
  • Minimizes latency and transmission time, leading to lower risk of transmission collisions or interference.
  • Improves energy efficiency, crucial for battery-operated or energy-harvesting devices.
  • Supports reliable and robust data transfer in crowded or uncoordinated wireless environments.
  • Allows flexible and scalable operation as the payload can vary without changing the basic transmission structure.
  • Facilitates backward compatibility and incremental upgrades in existing systems by maintaining fixed packet structures while adapting payload lengths.
  • Reduces need for additional signaling data (such as preambles), further decreasing power and bandwidth usage.
