Dual-Standard Wireless Direct Connection Control for Remote Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The widespread use of IEEE802.11ah wireless communication standard allows for wide-area connections, increasing the likelihood of unintended direct connections with mobile devices, reaching the connection limit and preventing legitimate users from establishing direct connections.
Innovation Solution
Implementing a dual communication system with both IEEE802.11ah for wide-area communication and IEEE802.11ac for small-area communication, allowing the apparatus to control the type of connection based on device location and displaying prompts to use the higher data transfer rate standard for direct connections.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the image forming apparatus supports the standard 11ah for wide-area communication, then the reachable range of radio waves is extended to more than a 1 km radius, but the number of mobile terminals that can establish direct connection reaches the upper limit value, preventing legitimate users from using the direct connection
Solution Approach 1:
The patent segments the wireless communication functionality into two distinct standards: 11ah for wide-area infrastructure connection and 11ac for small-area direct connection. This segmentation allows the system to simultaneously support both wide coverage and direct connection capabilities without interference, resolving the contradiction between extended reachable range and direct connection availability.
2Ease of operation
If the mobile terminal stores connection information after first-time connection, then automatic reconnection is enabled improving convenience, but unintended automatic direct connections occur with remote mobile devices
Solution Approach 1:
The patent introduces an intermediary authentication mechanism that verifies whether a mobile terminal is within the acceptable connection range before allowing automatic reconnection. This intermediary check prevents remote devices from establishing unintended direct connections while preserving the convenience of automatic reconnection for legitimate devices.
3Quantity of substance
If the number of directly connected mobile terminals reaches the upper limit, then the connection management becomes constrained, but legitimate users who desire to use direct connection cannot do so
Solution Approach 1:
The patent segments the connection types into infrastructure connection (via router) and direct connection (peer-to-peer), allowing the system to accommodate multiple mobile terminals through infrastructure connection while reserving direct connection capability for legitimate users who need it, thus resolving the contradiction between connection quantity and direct connection adaptability.
Data Source
AI summary
An information processing apparatus capable of preventing remote mobile devices from performing automatic direct connection. The information processing apparatus is capable of establishing wireless direct connection to a mobile terminal by using wireless communication via a first communication section conforming to a first wireless communication standard and wireless communication via a second communication section conforming to a second wireless communication standard which is higher in data transfer rate for a smaller area than the first wireless communication standard. Selection menus for configuring settings for establishing the direct connection to the mobile terminal are sequentially displayed on a display section, and a user performs selection operations according to the selection menus, whereby the wireless direct connection to the mobile terminal via the second communication section is established.
