Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing intermediate-range wireless communication technologies are unreliable and prone to interference, making them unsuitable for applications requiring interactivity and real-time communication, especially in populated areas where multiple devices share a common frequency or channel, and are not conducive for battery-powered devices that need to conserve power.
Innovation Solution
The development of low data rate electronic devices capable of wireless communication at ranges of thousands of meters, which measure the quality of the communication link and apply varying levels of redundancy based on packet transmission success and failure history, and include an exterior indicator for user patience, allowing for reliable service in congested areas.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of stationary object
If intermediate-range wireless communication is used to extend communication distance, then communication range is improved, but reliability deteriorates due to interference from multiple devices sharing common frequencies
Solution Approach 1:
The communication channel is segmented into multiple frequency channels. Devices can switch between channels to avoid interference, dividing the single congested frequency into multiple less-congested pathways for communication.
Solution Approach 2:
The system dynamically adapts communication parameters including redundancy levels and patience indicators based on real-time channel conditions. This allows the system to optimize reliability for each transmission based on current interference levels.
2Productivity
If high data rate protocols are used to enable real-time audio and video streaming, then data throughput is improved, but vulnerability to interference increases
Solution Approach 1:
The system changes communication parameters dynamically, adjusting data rate, redundancy level, and patience indicator based on channel conditions. This allows optimization of both throughput and reliability by adapting to real-time environmental factors.
3Reliability
If redundancy techniques are applied to reduce interference effects, then communication reliability is improved, but data throughput decreases
Solution Approach 1:
The system dynamically adjusts the level of redundancy applied to each transmission based on current channel conditions and the specific data being transmitted. Critical data receives higher redundancy while less critical data uses lower redundancy, optimizing the trade-off between reliability and throughput.
4Ease of operation
If battery-powered devices operate continuously to maintain communication readiness, then responsiveness is improved, but power consumption increases
Solution Approach 1:
Battery-powered devices use periodic wake-up cycles combined with patience indicators. Devices sleep for extended periods then wake to check for messages, using the patience indicator to determine whether to remain awake or return to sleep, thereby reducing power consumption while maintaining necessary responsiveness.

AI summary
Disclosed herein are low data rate electronic devices capable of wireless communication at ranges of thousands of meters. These devices may be such things as keypads, door latches, occupancy monitors, sprinkler controllers and others in a campus or a collection of buildings. Devices may measure the quality of a communications link on a channel, and apply varying levels of redundancy based upon a recent history of success and failure of packet transmission to other distant devices, which measurement may be a value of badness increased as errors are encountered and decreased as packet communication is successful. Devices may include an exterior indicator as to the present latency in communication, permitting an expectation of how patient a user should be before finding an error has occurred. Detailed information on various example embodiments of the inventions are provided in the Detailed Description below, and the inventions are defined by the appended claims.
