Solution Overview
Problem
Modern computers with high clock frequencies for processors and memory interfere with wireless data transmission speeds, causing variability in transmission speeds based on distance from the wireless base station, and existing solutions do not effectively mitigate this interference without degrading local application performance.
Innovation Solution
Implementing a computing platform with a processor and memory that can adjust clock frequencies, using a radio frequency interference mitigation (RFIM) application to select between fast and slow frequencies based on the priority of local or networked applications, thereby optimizing data transmission speeds while minimizing interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If processor and memory operate at high clock frequencies, then computing performance is improved, but radio frequency interference with wireless data transmission increases
Solution Approach 1:
The system dynamically adjusts the clock frequency of the processor and memory based on real-time detection of wireless transmission conditions. When interference is detected, the frequency is reduced to mitigate harmful effects; when clear transmission conditions exist, the frequency is increased to maximize computing performance. This dynamic adjustment resolves the contradiction by making the system adaptable rather than fixed.
Solution Approach 2:
The invention changes the operating parameter (clock frequency) of the processor and memory based on the transmission environment. By monitoring wireless transmission quality and adjusting the frequency parameter accordingly, the system optimizes both computing performance and transmission reliability, resolving the contradiction between high performance and interference mitigation.
2Speed
If clock frequency is reduced to mitigate interference, then wireless data transmission speed is improved, but computing performance deteriorates
Solution Approach 1:
The system implements dynamic frequency adjustment based on real-time transmission conditions. Rather than maintaining a fixed low frequency, the system continuously monitors wireless transmission quality and adjusts the clock frequency dynamically. This allows the system to achieve high transmission speeds when needed while maintaining high computing performance when interference is minimal.
Solution Approach 2:
The system uses feedback from wireless transmission quality detection to adjust the clock frequency. The RFIM application monitors transmission conditions and provides feedback to the processor and memory, enabling them to adjust their operating frequency accordingly. This feedback mechanism ensures optimal balance between transmission speed and computing performance.
3Object-affected harmful factors
If clock frequency is adjusted based on transmission conditions, then interference mitigation is improved, but system complexity increases
Solution Approach 1:
The system implements self-service interference mitigation through automated detection and adjustment. The RFIM application automatically monitors transmission conditions and adjusts clock frequency without requiring manual user intervention or complex external control systems. This self-service approach reduces the practical complexity despite the underlying technical complexity of the adjustment mechanism.
Solution Approach 2:
The RFIM application serves multiple functions: it detects transmission conditions, determines interference levels, and adjusts clock frequency. By consolidating these functions into a single multi-functional component, the system reduces overall complexity compared to having separate dedicated systems for each function.

AI summary
The present disclosure provides intelligent radio frequency interference mitigation in a computing platform. The computing platform includes a processor, a memory, a system clock and a wireless network interface. The system clock can be controlled so that the processor and/or the memory may operate at a slow frequency or a fast frequency. The wireless network may operate on a radio channel that experiences radio frequency interference at the fast frequency. The system clock may be intelligently controlled to select the slow frequency to reduce radio frequency interference to prioritize execution of a network application, or to select the fast frequency to increase processor speed and prioritize execution of a local application.
