IoT Relay Packet Compression for Range and Power
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless IoT communication protocols face limitations such as range constraints, power inefficiency, and susceptibility to interference, especially in RF-noisy environments, due to high data speed requirements and regulatory power output limitations, which hinder the ubiquity of IoT networks.
Innovation Solution
A method that reduces packet size and uses a lower-bandwidth communication protocol to transmit a reduced packet with a server identifier and data payload, allowing a relay device to communicate with a control server and present an image of direct communication to remote devices, thereby extending range and conserving power while maintaining a two-way connection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If high data speed protocols (Wi-Fi, Bluetooth, Zigbee) are used for IoT communication, then data transmission speed is improved, but range is reduced and power consumption increases
Solution Approach 1:
The patent extracts only the essential data from IoT devices, removing unnecessary headers and metadata. By sending only critical information (e.g., sensor readings, status changes) rather than complete data packets, the system achieves reliable communication at lower data speeds, thereby extending range and reducing power consumption while maintaining essential functionality
Solution Approach 2:
The patent applies partial action by transmitting only a subset of the full data set - specifically, only the most important measurements or status changes are communicated. This partial transmission approach reduces the data volume significantly, allowing use of lower-speed protocols that have longer range and lower power requirements, while still providing sufficient information for effective device control and monitoring
2Length of moving object
If maximum power output is used for wireless transmission to extend range, then communication range is improved, but power consumption increases and battery life decreases
Solution Approach 1:
The patent extracts and transmits only essential data elements, reducing the total data volume. This allows the system to use lower transmission power while maintaining reliable communication, thereby extending battery life without sacrificing range. The reduced data payload means less energy is required for each transmission cycle
Solution Approach 2:
The patent changes the data transmission parameters by reducing packet size and eliminating unnecessary protocol overhead. This parameter optimization allows the system to operate at lower power levels while maintaining effective communication range, directly addressing the contradiction between range and power consumption
3Reliability
If standard protocol data packets with full headers are transmitted, then communication completeness is improved, but data transmission overhead increases and range decreases
Solution Approach 1:
The patent systematically removes unnecessary components from standard protocol packets, keeping only the essential data elements. By extracting and transmitting only critical information (sensor readings, status changes, minimal identifiers), the system maintains communication reliability while dramatically reducing data overhead, thereby extending effective range
4Reliability
If devices transmit at maximum power levels to ensure stable links, then connection reliability is improved, but power consumption increases and battery life decreases
Solution Approach 1:
The patent extracts minimal essential data for transmission, reducing the energy required per transmission event. This allows devices to maintain reliable connections with lower power output, extending battery life while preserving connection stability through more frequent, lower-power transmission cycles
Solution Approach 2:
The patent implements periodic transmission of essential data at optimized intervals. By sending compressed, minimal data packets periodically rather than continuously at full power, the system maintains connection reliability while significantly reducing average power consumption and extending battery operational life

AI summary
A method for communicating between a remote device and a control server is described. The method include receiving a reduced packet when a reduced server identifier matches a control server, identifying the control server, constructing a device network packet, sending the device network packet to the control server, accepting a control network packet, building a reduced control packet, and transmitting the reduced control packet to the remote device.
