Frequency Array Sorting for Multi-Protocol Mobile Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile communication devices experience operating errors and prolonged frequency selection times due to frequency overlaps between different wireless communication protocols, leading to incapacitation in finding suitable frequencies for data transmission or reception.
Innovation Solution
A technique that sorts frequency arrays to prioritize non-shared frequencies over shared ones by identifying and adjusting frequency selection parameters based on signal strength differences, ensuring that mobile devices attempt to use non-overlapping frequencies first, thereby reducing the time to locate a suitable frequency for communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the mobile device uses a conventional frequency selection method without distinguishing shared frequencies, then the frequency selection process is simple, but the device experiences operating errors and prolonged selection times due to protocol conflicts on shared frequencies
Solution Approach 1:
The frequency array is segmented into two distinct subsets: shared frequencies and non-shared frequencies. This segmentation allows the device to selectively process frequencies based on their protocol compatibility, avoiding conflicts while maintaining efficient selection. The transceiver logic separates frequency handling by identifying which frequencies are shared between protocols and which are dedicated to a single protocol.
Solution Approach 2:
The device performs preliminary identification of shared frequencies before conducting frequency selection. By pre-processing the frequency array to mark shared frequencies, the device avoids the need to resolve protocol conflicts during the actual selection process, thereby improving both speed and reliability of frequency acquisition.
2Adaptability or versatility
If the mobile device attempts to use shared frequencies, then more frequency options are available, but the device becomes confused and incapacitated due to receiving data from multiple protocols simultaneously
Solution Approach 1:
The harmful effect of shared frequencies is extracted and isolated by creating a separate subset for shared frequencies. This allows the device to acknowledge the availability of these frequencies while preventing them from causing operational confusion. The transceiver logic extracts shared frequencies from the main selection pool and handles them differently, maintaining device operability.
Solution Approach 2:
The transceiver logic acts as an intermediary between the frequency array and the communication protocol layer. It mediates frequency selection by filtering and prioritizing non-shared frequencies, thereby preventing direct conflict between multiple protocols while still allowing access to shared frequencies when necessary.
3Reliability
If the mobile device scans all frequencies to find a suitable non-shared frequency, then communication reliability is improved, but the time to locate a suitable frequency becomes excessively long
Solution Approach 1:
The frequency array is pre-processed to identify and separate shared frequencies before the actual frequency selection occurs. This preliminary action creates an optimized selection pool where non-shared frequencies are readily identifiable, eliminating the need for time-consuming scans during operation while ensuring reliable communication.
Solution Approach 2:
Different quality attributes are applied to different frequencies based on their protocol characteristics. Non-shared frequencies are marked with high priority and reliability attributes, while shared frequencies are marked with lower priority. This local differentiation allows the device to quickly select reliable frequencies without exhaustive scanning.
Data Source
AI summary
A system comprises transceiver logic that receives signals on each of an array of frequencies. The transceiver logic is adapted to communicate using a first communication protocol. Processing logic couples to the transceiver logic. The processing logic identifies from among the array of frequencies a subset of shared frequencies that carry data transmitted using a second communication protocol. The processing logic adjusts frequency selection parameters in accordance with the identification. The processing logic uses the adjusted frequency selection parameters to select a target frequency from the array of frequencies to carry data.
