Fleet Vehicle Network Sharing Under Wireless Power Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle network technologies face challenges in optimizing signal coverage and throughput due to regulatory limits on wireless transmission power, particularly when vehicles support multiple cellular network technologies like 4G and 5G simultaneously.
Innovation Solution
A vehicle system that detects nearby vehicles within a predefined range and optimizes network configuration by activating one network technology while deactivating another, allowing for vehicle-to-vehicle communication to enhance coverage and throughput, thereby complying with regulatory power limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a mobile device supports multiple wireless technologies (4G and 5G) simultaneously, then network coverage and connectivity are improved, but transmit power must be reduced to comply with governmental regulations
Solution Approach 1:
The patent segments the wireless communication function across multiple vehicles in a fleet. Instead of requiring each individual vehicle to support and transmit on multiple network technologies simultaneously, the fleet collectively supports multiple technologies by having different vehicles use different technologies (4G or 5G) based on regulatory requirements in their respective geographic locations.
Solution Approach 2:
The patent introduces a fleet manager as an intermediary that coordinates network technology selection and power transmission across the fleet. The fleet manager receives location information, determines appropriate network technologies for each vehicle based on geographic regulations, and manages the collective network support to achieve compliance while maintaining connectivity.
2Reliability
If transmit power is reduced to comply with regulatory limits, then governmental regulations are satisfied, but signal coverage and throughput are degraded
Solution Approach 1:
The patent merges the network capabilities of multiple vehicles in a fleet to achieve collective compliance and performance. By combining the transmitted signals and capabilities of multiple vehicles, the fleet achieves regulatory compliance in each location while maintaining overall network throughput and coverage through the aggregated capacity of all vehicles.
Solution Approach 2:
The patent adds a spatial dimension to network compliance by allowing different vehicles to operate on different network technologies (4G or 5G) depending on their geographic location. This dimensional approach enables the fleet to satisfy local regulatory requirements while maintaining overall system performance through distributed multi-technology support.

AI summary
A vehicle comprises a processor, programmed to responsive to detecting a fleet within a predefined range, join the fleet via a wireless connection, and optimize network configuration of the fleet by activating a first network technology on the vehicle, deactivating a second network technology, and commanding at least one vehicle of the fleet via the wireless connection to deactivate the first network technology.
