Single Radio Multiplexing High-Throughput Low-Latency Links
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in simultaneously maintaining high-throughput and low-latency connections using a single wireless interface radio, as they often require switching between different frequency bands and time allocations, which can lead to missed data transmissions and synchronization issues with client devices.
Innovation Solution
A method is implemented where a single wireless interface radio configures non-overlapping time and frequency allocations to establish both high-throughput and low-latency links, allowing for dynamic adjustments in channel switching to ensure reliable communication by extending or shortening time allocations based on ongoing transmissions, and using virtual clients to manage access point timing.

Engineering Contradiction Analysis
1Adaptability or versatility
If a single wireless interface radio switches between different frequency bands and time allocations to maintain both high-throughput and low-latency connections, then both types of connections can be maintained simultaneously, but data transmissions may be missed and synchronization issues with client devices occur
Solution Approach 1:
The patent segments the time allocations into non-overlapping time periods, dedicating specific time slots to either high-throughput connections or low-latency connections. This temporal segmentation allows the single radio to systematically switch between different connection types without interference, ensuring that each connection type receives dedicated attention while maintaining overall system reliability
Solution Approach 2:
The patent implements dynamic adjustment of time allocation durations based on ongoing transmission status. When a transmission is detected to be incomplete at the boundary of time allocations, the system dynamically extends the current time allocation and adjusts subsequent allocations accordingly. This dynamic approach prevents data loss and maintains synchronization while preserving the ability to support both connection types
2Productivity
If fixed time allocations are used for switching between frequency bands, then the radio can systematically manage multiple connections, but ongoing transmissions may be interrupted causing data loss
Solution Approach 1:
The patent employs feedback mechanisms where the system continuously monitors transmission status at the boundaries of fixed time allocations. When feedback indicates that a transmission is ongoing and incomplete, the system responds by extending the current time allocation. This feedback-driven adjustment ensures that fixed time allocations do not interrupt ongoing transmissions, thereby maintaining both systematic management and transmission reliability
Solution Approach 2:
The system performs preliminary checks at the boundaries of time allocations to detect ongoing transmissions before switching frequency bands. By proactively identifying incomplete transmissions in advance, the system can adjust time allocations preemptively, preventing data loss while maintaining the structured approach to managing multiple connections

AI summary
A computing device (such as a computer gaming console) uses only a single radio to concurrently communicate with a wireless network access point and wireless client devices such as game controllers or peripherals. To establish and maintain both a high-throughput link with the access point, and a low-latency link with the client device(s), the single Wi-Fi radio of the computing device is configured to periodically switch between a channel used for the high-throughput link and a different channel that is used for the low-latency link—thus implementing a combination of frequency division multiplexing (FDM) and time division multiplexing (TDM). The console may use aspects of the Wi-Fi protocol standard to ensure that periodically switching its single radio between the two channels is accomplished while maintaining reliable communication on both channels.
