Communication System Using Skywave Triggering for Low Latency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
High latency in fiber optic and satellite communications across vast distances leads to unacceptable delays in time-sensitive activities, such as financial transactions and distributed computing, due to the inherent limitations in communication mediums and equipment.
Innovation Solution
A communication system and method that utilizes separate communication links for command data and triggering data, where command data is transmitted over high bandwidth but high latency links, and triggering data is transmitted over low bandwidth but low latency links, such as through skywave propagation, to reduce overall execution time for complex actions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If command data and triggering data are transmitted over the same high bandwidth communication link, then data completeness is improved, but execution time increases due to latency
Solution Approach 1:
The patent segments the data transmission into two separate channels: command data transmitted over high bandwidth links (fiber optic, satellite) and triggering data transmitted over low latency links (ground wave, line-of-sight radio). This segmentation allows each type of data to use the most appropriate transmission medium for its specific requirements, resolving the contradiction between data completeness and execution time.
Solution Approach 2:
The patent introduces an intermediary mechanism where triggering data acts as a trigger that activates pre-received command data. The triggering data includes identifiers that match with stored command data, allowing the system to execute commands quickly once the trigger arrives, without waiting for the full command data set to be transmitted over the high latency link.
2Quantity of substance
If command data is transmitted over high bandwidth links, then data transmission capacity is improved, but transmission speed deteriorates due to inherent latency
Solution Approach 1:
The patent applies preliminary action by transmitting and storing command data in advance over high bandwidth links before the triggering event occurs. When the triggering data arrives via the low latency link, the command data is already available at the receiving end, eliminating the need to wait for its transmission and thus achieving fast execution despite using high bandwidth links for command data.
3Loss of time
If triggering data is transmitted over low bandwidth links, then latency is reduced, but data transmission capacity is limited
Solution Approach 1:
The patent applies local quality by assigning different transmission characteristics to different types of data. Triggering data, which requires low latency and contains only critical identification information, is transmitted over low bandwidth but low latency links. Command data, which requires high capacity and can tolerate higher latency, is transmitted over high bandwidth links. This localized optimization resolves the contradiction between latency and transmission capacity.

Function Achieved in This Case
This approach significantly reduces the time required to execute complex time-sensitive actions by ensuring that triggering data is received promptly, thereby minimizing delays and improving the efficiency of operations across long distances.
Implementation Method 1

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 data with a lower latency across a substantial portion of the earth's surface. The two communications links may be used together to coordinate various activities such as the buying and selling of financial instruments.
