Hybrid NFC-Wi-Fi System for Proximity-Free Device Pairing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional information processing systems require users to bring devices into proximity for communication via IEEE 802.15.1, limiting user convenience, especially when dealing with non-portable apparatuses.
Innovation Solution
An information processing system that detects a connection target apparatus, generates apparatus information, and transmits it to a server via a second communication path, allowing the server to generate connection information for establishing communication via a first communication path, such as IEEE 802.15.1, without physical proximity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If NFC communication is used to identify the communication target apparatus, then the communication range is limited to several dozen centimeters, but this improves the ability to identify the correct target apparatus
Solution Approach 1:
The patent divides the communication establishment process into two distinct phases: (1) NFC-based target identification phase for accurate device selection, and (2) Wi-Fi-based data communication phase for actual data transfer. This segmentation allows each communication method to be optimized for its specific function, resolving the contradiction between accurate identification and user convenience.
Solution Approach 2:
The patent introduces a server as an intermediary that stores connection information for target apparatuses. The information processing apparatus communicates with the server via NFC to obtain connection information, which then enables Wi-Fi communication with the target apparatus. This intermediary mechanism allows the system to overcome the limited NFC range while maintaining accurate target identification.
2Reliability
If the information processing apparatus and connection target apparatus are brought into proximity for NFC communication, then target identification is enabled, but this increases the burden on the user when dealing with non-portable apparatuses
Solution Approach 1:
The patent implements preliminary action by having the target apparatus pre-register its connection information with the server before actual communication is needed. When communication is initiated, the information processing apparatus only needs to query the server via NFC (which can be done from a distance) to obtain pre-prepared connection information, eliminating the need for physical proximity and reducing user burden while maintaining reliable communication establishment.
3Adaptability or versatility
If NFC communication is used for device identification, then the system works well for portable apparatuses, but this reduces compatibility and convenience for non-portable apparatuses
Solution Approach 1:
The patent implements universality by designing a hybrid communication system that can handle both portable and non-portable apparatuses through the same workflow. The NFC-Wi-Fi combination approach works regardless of the portability of the target apparatus, making the system universally applicable while maintaining operational convenience for all device types.

AI summary
A system and method for information processing is provided. In an embodiment of the present system and method, a connection target apparatus is detected at an information processing apparatus. Upon detection, the information processing apparatus generates apparatus information and transmits the apparatus information to a server via a communication path. Based on the apparatus information, the server generates connection information and transmits the connection information to the information processing apparatus. The information processing apparatus may use the connection information to establish communication with the connection target apparatus via another communication path.
