Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems face challenges in providing high data rates and efficient multimedia content delivery to mobile devices due to varying channel conditions and power consumption issues, particularly in adapting broadcasting services for mobility.
Innovation Solution
A system and method that utilize a combination of DVB-H, cellular, IEEE 802.11, and IEEE 802.16 base stations to communicate multimedia content, where mobile terminals measure downlink channel conditions and route content based on bit-error-rate (BER) indicators, dynamically selecting the best communication paths to optimize data transfer and reduce power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If broadcasting services are adapted for mobility using existing mobile communication networks, then service portability is improved, but data transmission bit rate is insufficient
Solution Approach 1:
The system dynamically adapts between different transmission modes (broadcasting and telecommunications) based on mobility conditions. The mobile device can switch between receiving multimedia content via broadcasting when stationary and using cellular communication when moving, optimizing both service portability and data transmission rate according to real-time conditions.
2Area of stationary object
If high power transmitters are used for broadcasting to cover broad service areas, then coverage area is improved, but power consumption increases
Solution Approach 1:
The system merges broadcasting and telecommunications networks, allowing mobile devices to receive multimedia content through broadcasting when in coverage areas (reducing power consumption compared to cellular), and switch to cellular communication when broadcasting coverage is unavailable, thus achieving both broad coverage and energy efficiency.
Solution Approach 2:
The mobile device autonomously monitors broadcasting coverage availability and automatically switches between broadcasting and cellular reception modes without user intervention, optimizing power consumption based on real-time coverage conditions while maintaining continuous service.
3Speed
If multiple downlink communication paths are used for multimedia content delivery, then data transfer rate is improved, but system complexity increases
Solution Approach 1:
The system segments multimedia content into different data streams that can be transmitted through multiple downlink paths (broadcasting and cellular). The mobile device independently receives and reassembles these segmented streams, achieving high data transfer rates while keeping the overall system architecture relatively simple through modular content delivery.
