Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If cellular service providers build infrastructure such as cellular towers, then market share and service coverage are improved, but infrastructure costs and real estate acquisition expenses increase
Solution Approach 1:
The broadband access gateway serves as an intermediary device that bridges cellular networks and local area networks. It receives cellular signals via wireless interface and provides them through broadband connection, eliminating the need for expensive cellular tower infrastructure in local areas while maintaining service coverage.
2Reliability
If cellular infrastructure is established to improve signal coverage, then service availability is improved, but the cost of backbone links and core network traffic handling increases
Solution Approach 1:
The gateway acts as a mediator that receives cellular signals through its wireless interface and forwards them via broadband connection to the cellular network. This eliminates the need for expensive backbone links and core network infrastructure while ensuring reliable signal penetration in local areas.
3Ease of operation
If consumers share multimedia information electronically across devices, then convenience of information exchange is improved, but control over access and information security deteriorates
Solution Approach 1:
The gateway implements a registration system where devices must register with the gateway before accessing shared multimedia information. The gateway maintains control over access by requiring authentication and providing feedback on access requests, ensuring security while enabling convenient sharing.
Solution Approach 2:
The gateway serves as an intermediary between devices seeking to share multimedia information. It mediates access control by requiring device registration and authentication, thereby maintaining security while enabling convenient electronic information exchange across devices.
4Measurement precision
If cable connections and software configuration are used for information transfer, then information sharing accuracy is improved, but operational complexity and user intimidation increases
Solution Approach 1:
The gateway enables devices to automatically register and share multimedia information without requiring manual cable connections or complex software configuration. The system performs self-service registration and information exchange, maintaining accuracy while eliminating operational complexity for users.
Data Source
AI summary
A system and method of registering or exchanging information about the availability of multimedia information and services is disclosed. Access devices in a wireless local area network (WLAN) and/or personal area network (PAN) may register, with a wireless broadband access gateway, selected information about multimedia information and services that they have and may share. Information about the available multimedia information and services may be shared by the wireless broadband access gateway with other access devices within the coverage area of the WLAN or PAN. Access devices may then access the multimedia information and services of other access devices via the wireless broadband access gateway, based upon information identifying and authenticating the recipient. A broadband connection permits the gateway to pass multimedia information and service activity to and from the access devices within the coverage area of the WLAN or PAN.
