Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The growing demand for wireless communication bandwidth outpaces the capacity of existing wireless infrastructure, leading to issues like dropped calls, congestion, and increased deployment and operating costs, with existing solutions struggling to efficiently deploy and manage access points, especially in home environments due to interference and high costs.
Innovation Solution
The implementation of a 'cognitive radio you share, trust and access locally' (CRYSTAL) system, which virtualizes radio access points, allowing multiple wireless technologies to be combined on a single platform and managed as a cloud, enabling dynamic deployment and management of virtual base stations to address capacity needs and interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If multiple specialized access points are deployed for different wireless technologies, then wireless capacity and coverage are improved, but deployment cost and device complexity increase significantly
Solution Approach 1:
The patent combines multiple wireless access technologies (LTE, WiMax, GSM, Wi-Fi) into a single multi-radio access point platform. This consolidation allows the system to provide diverse wireless capacity while reducing the number of separate devices needed, thereby lowering deployment complexity and cost.
Solution Approach 2:
The access point is designed with multi-functionality to support multiple wireless standards simultaneously. A single device can serve as LTE base station, WiMax access point, GSM base transceiver, and Wi-Fi router, eliminating the need for multiple specialized devices and simplifying deployment.
2Quantity of substance
If access points are deployed ubiquitously to improve spatial diversity, then wireless capacity increases, but deployment cost and operating expense increase
Solution Approach 1:
By merging multiple wireless technologies into a single access point, the system reduces the total number of devices required for ubiquitous deployment. Fewer devices mean lower cumulative operating costs including power consumption, maintenance, and management overhead.
3Reliability
If home-deployed femtocells are used to improve local coverage, then wireless access is improved, but deployment difficulty increases due to interference and configuration complexity
Solution Approach 1:
The femtocell system incorporates self-configuration and automatic interference management capabilities. The access point can autonomously detect the wireless environment, select appropriate frequencies, and optimize parameters without requiring manual configuration by the home user, thereby simplifying deployment while maintaining reliable local coverage.

AI summary
CRYSTAL “Cognitive radio you share, trust and access locally” (CRYSTAL) is a virtualized cognitive access point that may provide for combining multiple wireless access applications on a single hardware platform. Radio technologies such as LTE (Long-Term Evolution), WiMax (Worldwide Interoperability for Microwave Access), GSM (Global System for Mobile Communications), and the like can be supported. CRYSTAL platforms can be aggregated and managed as a cloud, which provides a model for access point sharing, control, and management. CRYSTAL may be used for scenarios such as neighborhood spectrum management. CRYSTAL security features allow for home/residential as well as private infrastructure implementations.
