Server-Based Wireless Interference Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Wireless communication systems face challenges in minimizing interference, especially when receivers or transmitters move, as existing methods are inadequate in preventing interference in dynamic environments, leading to performance degradation and potential regulatory violations.
Innovation Solution
A server in a wireless communication network determines acceptable communication parameters for terminals based on their geographic location, generating instructions to avoid interference with unintended receivers by adjusting transmission parameters, and terminals implement these changes to ensure non-interfering communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If transmitters are allowed to move to improve network flexibility and coverage, then adaptability is improved, but interference with unintended receivers increases
Solution Approach 1:
The system implements a feedback mechanism where the server continuously receives location information from mobile transmitters, recalculates acceptable communication parameters based on current positions of both the transmitter and unintended receivers, and sends updated instructions to the transmitter. This closed-loop control enables the transmitter to adapt its transmission parameters dynamically while avoiding interference, resolving the contradiction between mobility and interference prevention.
Solution Approach 2:
The system transitions from static interference avoidance (fixed transmitter locations) to dynamic interference avoidance (mobile transmitter locations). The server continuously updates acceptable communication parameters as the transmitter moves, allowing the system to maintain optimal performance while adapting to changing spatial relationships between transmitter and receivers.
2Reliability
If transmission parameters are dynamically adjusted to avoid interference, then interference avoidance is improved, but device complexity increases
Solution Approach 1:
The server acts as an intermediary that centralizes the complex calculations for determining acceptable communication parameters. Instead of requiring the mobile transmitter to independently calculate and adjust parameters, the server performs the interference analysis and sends ready-to-use parameter instructions to the transmitter, simplifying the transmitter's role while maintaining reliable interference avoidance.
Solution Approach 2:
The system enables the transmitter to autonomously adjust its communication parameters by receiving and implementing server instructions without requiring manual intervention. The transmitter self-regulates its transmission based on location feedback and server guidance, reducing operational complexity while maintaining high reliability in interference avoidance.

AI summary
In one embodiment, a server of a first wireless communication network receives a wireless communication originated by a terminal of the first wireless communication network, the wireless communication containing a current geographic location of the terminal as determined by the terminal. The server may then determine acceptable communication parameters for the terminal to communicate on the first wireless communication network, e.g., based on preventing transmission by the terminal that might interfere with operation of one or more unintended receivers. The server then generates an instruction message for the terminal based on the acceptable communication parameters, and transmits the instruction message toward the terminal to cause the terminal to only continue transmitting according to acceptable communication parameters.
