Protocol Frame Fragmentation for Wireless Interference Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interference occurs between wireless communication protocols like IEEE 802.11 and Bluetooth when they operate in similar frequencies, leading to distorted or inhibited communication, which existing technologies have not adequately addressed.
Innovation Solution
A communications device is configured to transmit data frames with a predetermined time period between them, and a second data frame is fragmented into subframes to be transmitted during these intervals, allowing for coordinated transmission and reducing interference by determining the optimal timing for each protocol's data frames.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wireless protocols operate in similar frequencies simultaneously, then communication versatility is improved, but interference between protocols increases
Solution Approach 1:
The patent segments the transmission timeline by dividing it into distinct time periods, with first time periods dedicated to first protocol transmissions and second time periods dedicated to second protocol transmissions. This temporal segmentation allows multiple protocols to coexist in the same frequency band without interfering with each other, as they transmit during separate time intervals.
Solution Approach 2:
The patent implements periodic action by establishing a repeating pattern of time periods where the first protocol transmits during first time periods and the second protocol transmits during second time periods. This periodic structure ensures that each protocol has dedicated transmission windows, preventing simultaneous transmissions that would cause interference while maintaining regular communication cycles for both protocols.
2Productivity
If data frames are transmitted continuously, then productivity is improved, but interference between protocols increases
Solution Approach 1:
The patent segments continuous data transmission into discrete time-period-based transmissions. Instead of allowing continuous uninterrupted transmission, the system divides transmission into first time periods for the first protocol and second time periods for the second protocol, maintaining productivity through structured scheduling while eliminating interference through temporal separation.
Solution Approach 2:
The patent applies dynamics by making the transmission schedule adaptable and configurable. The time periods, their durations, and the protocols assigned to each period can be dynamically adjusted based on communication needs, allowing the system to optimize between productivity and interference prevention depending on the specific operational context.
3Reliability
If time periods for protocol transmission are extended, then communication quality is improved, but loss of time for other protocols increases
Solution Approach 1:
The patent uses periodic action to create a balanced repeating cycle where each protocol receives adequate transmission time in its designated time periods. By structuring the transmission schedule as a periodic pattern, the system ensures that communication quality is maintained for both protocols over time, while the cyclic nature prevents permanent time loss, as each protocol gets regular opportunities to transmit.
Solution Approach 2:
The patent applies parameter changes by allowing the durations of first and second time periods to be configured and adjusted. This enables optimization of communication quality for each protocol by setting appropriate time period lengths, while also balancing the overall schedule to minimize time loss for either protocol. The parameters can be changed based on the specific requirements of the communication scenarios.
