WiFi Hotspot Frequency Band Staggering for Multi-Link Interference Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
When mobile phones distribute data into multiple links for transmission, mutual interference between wireless modules occurs due to similar or identical frequency bands, leading to increased error and decreased data transmission rates.
Innovation Solution
A WiFi hotspot management method that involves obtaining network information of an initial network resource, sending a hotspot enabling command to an external device, and connecting to a target WiFi hotspot with a staggered frequency band, thereby reducing inter-frequency band interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If data are distributed into multiple links for transmission through similar or identical frequency bands, then data transmission capacity is increased, but mutual interference between wireless modules occurs leading to increased error rate
Solution Approach 1:
The patent changes the frequency band parameter of the WiFi hotspot to be different from the initial network resource's frequency band. By adjusting this critical parameter, the system avoids mutual interference between wireless modules while maintaining multi-link data transmission capability, thus resolving the contradiction between transmission rate and error rate
Solution Approach 2:
The patent introduces frequency band differentiation as an additional dimension for link management. Instead of using multiple links at the same frequency level, the system creates links operating at different frequency bands, effectively adding a dimensional separation that prevents interference while preserving parallel transmission capacity
2Productivity
If multiple wireless modules simultaneously receive and transmit data in similar frequency bands, then concurrent transmission capability is enhanced, but mutual interference increases leading to decreased data transmission rate
Solution Approach 1:
The patent modifies the frequency band parameter of the WiFi hotspot to differ from the initial network resource. This parameter change enables concurrent transmission across multiple links without mutual interference, as each link operates in a distinct frequency band, thereby resolving the contradiction between concurrent capability and harmful interference
Solution Approach 2:
The patent segments the frequency spectrum into different bands for different transmission links. By dividing the frequency resources into separate segments (different frequency bands), the system allows multiple wireless modules to transmit concurrently without interfering with each other, thus resolving the contradiction
