Multiradio Control System for Wireless Modem Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Simultaneously operating radio modems in wireless communication devices often cause interference due to extraneous effects, leading to performance degradation and errors in communication networks, as they cannot function optimally when limited to operating one medium at a time.
Innovation Solution
A multiradio control system (MCS) is integrated into the device, which includes a multiradio controller (MRC) that communicates directly with radio modems through a dedicated interface to monitor and schedule their operations, enabling or disabling them to avoid conflicts and minimize interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple radio modems operate simultaneously in a wireless communication device, then communication functionality and versatility are improved, but interference between modems occurs causing performance degradation and errors
Solution Approach 1:
A multiradio controller (MRC) is introduced as an intermediary component between the master control system and multiple radio modems. The MRC receives control information from the master control system and distributes coordinated control signals to multiple radio modems, enabling them to operate simultaneously while avoiding interference through centralized scheduling and timing coordination.
2Reliability
If radio modems are limited to operating one medium at a time, then interference between modems is avoided, but communication efficiency and productivity deteriorate
Solution Approach 1:
The multiradio controller implements periodic scheduling of radio modem operations, allocating specific time slots and transmission windows to different radio modems. This periodic coordination allows multiple modems to operate in an time-division multiplexed manner, maintaining communication stability while significantly improving overall system productivity and efficiency.
3Reliability
If a centralized control system manages multiple radio modems, then coordination and interference avoidance are improved, but device complexity increases
Solution Approach 1:
The control system is segmented into two functional parts: a master control system that handles high-level decision-making and a dedicated multiradio controller that handles radio-specific coordination. This segmentation allows the complex coordination tasks to be isolated in the MRC module, making the overall system more manageable and maintainable while improving coordination efficiency.

AI summary
A system for managing the simultaneous operation of a plurality of radio modems in a single wireless communication device (WCD). The multiradio control may be integrated into the WCD as a subsystem responsible for scheduling wireless communications by temporarily enabling or disabling the plurality of radio modems within the device. The multiradio control system may comprise a multiradio controller (MRC) and a plurality dedicated radio interfaces. The radio interfaces are dedicated to quickly conveying delay sensitive information to and from the radio modems. The modems may further include control features that take information from the MRC as an input in determining the priority of messages to be sent out to a receiving device.
