Communication System Latency Reduction via Skywave Triggering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High latency in fiber optic and satellite communications across long distances leads to unacceptable delays in time-sensitive activities, such as financial transactions and distributed computing, due to inherent limitations in communication mediums and encoding processes.
Innovation Solution
A communication system that utilizes separate high and low latency communication links, with command data transmitted over high latency/high bandwidth links and triggering data sent over low latency/low bandwidth links, such as through skywave propagation, to reduce overall execution time for complex actions. This system also employs multiple encoding algorithms and error detection/correction methods to minimize transmission overhead and latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If data is transmitted over fiber optic cables across long distances, then bandwidth is high, but latency increases significantly
Solution Approach 1:
The patent segments data into two types: command data (large volume, low urgency) and triggering data (small volume, high urgency). Each type is transmitted over different communication links optimized for its specific requirements, resolving the contradiction between bandwidth and latency.
Solution Approach 2:
The patent introduces an intermediary encoding scheme that uses compact representations for triggering data. This intermediary format reduces the amount of data that needs to be transmitted over high-latency links, effectively mediating between the need for high bandwidth and low latency.
2Reliability
If multiple layers of encoding and error checking are added to ensure reliable delivery, then reliability improves, but transmission latency increases
Solution Approach 1:
The patent applies different encoding and error-checking strategies to different data types. Command data receives comprehensive error checking, while triggering data uses minimal or no error checking since it is small in size and can be quickly retransmitted if needed. This local differentiation resolves the contradiction between reliability and latency.
3Quantity of substance
If triggering data is transmitted over the same high bandwidth link as command data, then data volume capacity is maximized, but execution speed decreases
Solution Approach 1:
The patent segments the communication channel into two separate links: one for command data (high bandwidth, accepts high latency) and one for triggering data (low bandwidth, low latency). This segmentation allows each link to be optimized for its specific purpose, resolving the contradiction between data capacity and execution speed.

AI summary
A communication system uses multiple communications links, preferably links that use different communications media. The multiple communications links may include a high latency/high bandwidth link using a fiber-optic cable configured to carry large volumes of data but having a high latency. The communications links may also include a low latency/low bandwidth link implemented using skywave propagation of radio waves and configured to carry smaller volumes of triggering data with a lower latency across a substantial portion of the earth's surface. The triggering data may be sent in a data stream as data frames without headers, security information, or error checking codes. The two communications links may be used together to coordinate various activities such as the buying and selling of financial instruments.
