Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless data networks under 6 GHz are congested, while the mmWave frequency band offers unlicensed spectrum for high-speed data transfer, but mmWaves are susceptible to channel propagation loss due to their higher frequency and shorter wavelength, leading to signal path loss and potential data transfer interruptions.
Innovation Solution
An aggregate interface combining mmWave and WLAN interfaces, which monitors and dynamically adjusts frame assignment based on available bandwidth, using sequence numbering to ensure correct frame delivery despite potential out-of-order reception due to differing transmission speeds.

Engineering Contradiction Analysis
1Speed
If mmWave interface is used for high-speed data transfer, then data transfer speed is improved, but signal reliability deteriorates due to channel propagation loss
Solution Approach 1:
The patent combines mmWave interface and WLAN interface into an aggregate interface that operates simultaneously. The mmWave interface provides high-speed data transfer when conditions permit, while the WLAN interface provides reliable communication when mmWave signal quality degrades. The system dynamically switches between or combines both interfaces to maintain both speed and reliability.
Solution Approach 2:
The system dynamically changes operational parameters by monitoring signal quality metrics (RSSI, SNR) and adjusting the weight or activation of each interface accordingly. When mmWave signal quality is good, the system prioritizes mmWave for high speed; when quality degrades, it increases WLAN contribution to maintain reliability.
2Productivity
If frame assignment is dynamically adjusted between mmWave and WLAN interfaces, then network utilization is improved, but system complexity increases
Solution Approach 1:
The patent implements dynamic frame assignment where the system continuously monitors interface conditions and adjusts the distribution of data frames between mmWave and WLAN interfaces in real-time. This dynamic adjustment optimizes network utilization by utilizing both interfaces according to their current capacity and signal quality.
Solution Approach 2:
The system employs feedback mechanisms by monitoring signal quality metrics (RSSI, SNR) and transmission performance from both interfaces, then using this feedback to adjust frame assignment decisions. This closed-loop control enables adaptive optimization of network utilization while managing complexity through rule-based decision making.
3Loss of information
If sequence numbering is implemented to ensure correct frame delivery, then data integrity is improved, but processing overhead increases
Solution Approach 1:
The patent implements sequence numbering and frame tracking in advance before potential data loss occurs. By pre-establishing sequence identifiers and maintaining expected sequence state, the system can quickly detect out-of-order delivery or missing frames without extensive retransmission protocols, thus improving data integrity with minimal processing overhead.
