Coordinated Radio Modules for Interference Mitigation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile computing devices with multiple radios often experience signal degradation due to interference between co-located wireless communication technologies, such as cellular and data networking systems, which impairs communication applications.
Innovation Solution
The implementation of an apparatus with coordinated radio modules, where communications controllers exchange operational status information and control directives to schedule transmission and reception activities, preventing interference by synchronizing the operations of co-located transceivers across different wireless technologies.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple radios are co-located in a mobile device to provide various wireless communications capabilities, then the device can support multiple wireless technologies (cellular, satellite, mobile data networking), but transmissions by one radio interfere with reception by another radio causing signal degradation
Solution Approach 1:
A coordination module is introduced as an intermediary between multiple radio modules to manage and coordinate their operations. The coordination module receives status information from each radio module and generates control directives to prevent interference, thereby maintaining signal quality while enabling multiple wireless technologies to coexist in the same device.
2Productivity
If multiple radios operate simultaneously to handle different wireless technologies, then communication versatility is improved, but interference between radios causes signal degradation that impairs communication applications
Solution Approach 1:
The coordination module implements a feedback mechanism where each radio module transmits its status information (such as transmission/reception states) to the coordination module. Based on this feedback, the coordination module generates appropriate control directives to adjust radio operations and eliminate harmful interference, thereby maintaining high communication productivity across multiple wireless technologies.

AI summary
Techniques involving the coordination of wireless activities are disclosed. For example, an apparatus may include two or more transceivers. These transceivers may include a first transceiver to communicate wirelessly across cellular links, and a second transceiver to communicate wirelessly across wireless data networking links. The apparatus may also include controllers, each controlling wireless communications of a corresponding transceiver. Information may be exchanged with each other regarding operation of the transceivers. Through the exchange of such information, activity (e.g., transmission and reception of wireless signals) may be coordinated among the transceivers.
