Wireless IO Packet Polling via Scheduled Frames
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless peripheral input/output (IO) devices face challenges with high power consumption, increased latency, and data throughput limitations due to the one reception/one transmission (1RX/1TX) communication format, which leads to frequent mode-switching and potential data packet collisions.
Innovation Solution
The streamlined wireless communication packet polling and reception system orchestrates scheduled delivery of data packets from wireless IO devices, reducing the frequency of acknowledgment packets and mode-switching by transmitting polling packets that instruct IO devices to send data packets in specified time slots during scheduled data packet communication frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the 1RX/1TX communication format is used for wireless peripheral IO devices, then the communication protocol is simple to implement, but power consumption increases and data throughput is limited due to frequent mode-switching
Solution Approach 1:
The patent implements periodic action by using scheduled communication frames with predetermined time slots for data transmission and acknowledgment. Instead of immediate 1RX/1TX mode-switching for every packet, the system organizes communication into periodic frames where the radio remains in receive mode for multiple packets, reducing the frequency of mode-switching operations and thereby lowering power consumption.
Solution Approach 2:
The patent applies preliminary action by pre-scheduling communication frames and time slots before actual data transmission occurs. The system establishes a predetermined communication structure in advance, allowing the radio to stay in receive mode for multiple packets without frequent switching to transmit mode, thus reducing power consumption while maintaining protocol simplicity.
2Device complexity
If the 1RX/1TX communication format is used for wireless peripheral IO devices, then the communication protocol is simple to implement, but data throughput is limited due to frequent mode-switching
Solution Approach 1:
The patent implements periodic action by organizing communication into scheduled frames with multiple time slots dedicated to data transmission. This allows multiple packets to be transmitted during each frame while the radio remains in receive mode, increasing data throughput without requiring complex protocol changes, as the periodic structure is enforced at the scheduling level.
Solution Approach 2:
The patent applies preliminary action by pre-defining communication frames and allocating time slots for data transmission before communication occurs. This advance scheduling enables the system to maximize data throughput within each frame by keeping the radio in receive mode for multiple packets, without requiring complex real-time protocol negotiations.
3Reliability
If acknowledgment packets are sent for every received data packet in 1RX/1TX format, then data transmission reliability is maintained, but latency increases due to frequent mode-switching
Solution Approach 1:
The patent implements periodic action by consolidating acknowledgment transmissions into specific time slots within scheduled frames. Instead of immediately switching to transmit mode for every acknowledgment, the system waits for predetermined acknowledgment time slots, reducing the frequency of mode-switching and thereby decreasing latency while maintaining reliable acknowledgment of received packets.
Solution Approach 2:
The patent applies preliminary action by pre-scheduling acknowledgment time slots within communication frames before data transmission occurs. This allows the system to plan acknowledgment transmissions in advance, reducing the need for frequent real-time mode-switching between receive and transmit modes, thus lowering latency while preserving data transmission reliability.
4Speed
If frequent mode-switching is performed in 1RX/1TX format, then real-time communication responsiveness is maintained, but power consumption increases
Solution Approach 1:
The patent implements periodic action by using scheduled frames with predetermined time slots for data transmission and acknowledgment. This periodic structure allows the radio to remain in receive mode for multiple packets without frequent switching to transmit mode, reducing power consumption while maintaining communication responsiveness through the structured timing of data and acknowledgment transmissions.
Solution Approach 2:
The patent applies preliminary action by pre-scheduling communication frames and time slots before communication occurs. This advance planning allows the system to minimize mode-switching operations by keeping the radio in receive mode for multiple packets, thereby reducing power consumption while maintaining responsiveness through the predetermined communication structure.
