Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication devices rely on base stations for communication, limiting direct communication between nearby devices, especially in areas without infrastructure or during network outages.
Innovation Solution
Incorporating a short-range transceiver in wireless communication devices to enable direct communication between devices without relying on base stations, forming dynamic short-range networks that can adapt and change as devices move within range of each other.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless communication devices communicate via base stations, then network coverage and reliability are improved, but direct communication between nearby devices is limited and device complexity increases
Solution Approach 1:
The patent segments the communication system into two distinct modes: infrastructure-based mode (using base stations) and ad hoc mode (direct device-to-device communication). The wireless device can selectively switch between these modes depending on whether base stations are available, thereby reducing overall system complexity while maintaining reliability through mode diversity
Solution Approach 2:
The patent introduces a mode selection mechanism that acts as an intermediary, deciding whether to route communication through base stations or directly between devices. This intermediary layer manages the complexity by abstracting the decision-making process, allowing the system to maintain reliability through appropriate mode selection without requiring all devices to simultaneously support both complex infrastructure modes
2Area of stationary object
If wireless devices use base station infrastructure, then network coverage is improved, but direct communication between nearby devices is lost and adaptability decreases
Solution Approach 1:
The patent implements multi-functionality by enabling wireless devices to operate in multiple communication modes: infrastructure-based mode for wide area coverage and ad hoc mode for direct short-range communication. This universality allows the same device to adapt to different scenarios, maintaining both extensive coverage capability and direct communication capability without requiring separate dedicated systems
Solution Approach 2:
The patent introduces dynamic mode switching capability that allows the communication system to adapt in real-time based on environmental conditions. When base stations are available, the system dynamically switches to infrastructure mode for wide coverage; when base stations are unavailable, it dynamically transitions to ad hoc mode for direct communication, thereby maintaining both coverage and adaptability
3Productivity
If push-to-talk technology is used for group communication, then communication efficiency is improved, but direct device-to-device communication is still relayed via base stations and device complexity increases
Solution Approach 1:
The patent segments group communication functionality into infrastructure-based PTT (relayed through base stations) and ad hoc PTT (direct device-to-device). This segmentation allows the system to choose the simpler ad hoc PTT mode when devices are nearby, improving efficiency while reducing the complexity overhead of mandatory infrastructure relay protocols
Data Source
AI summary
User equipment (UE) is configured to automatically detect the presence of an access point (AP) in any one of a plurality of venues and to transmit identification information to the AP to authenticate the UE. The venue receiving the authentication request transfers the authentication request and identification information to an authentication server to automatically authenticate the UE whenever it is carried inside a venue. The venues may be coupled to a Cloud network with the authentication information stored on the Cloud network. Whenever the UE enters any of the venues, the UE is automatically authenticated when it comes within range of any AP within any of the venues. The venue may use an application program interface to provide advertising, coupons, web links, images, audio, video, streaming video, and the like to the UE. The venue may direct the UE to a website or provide a link to the website.
