Selective SSID Broadcast for Multi-Standard Wireless Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In image forming apparatuses supporting multiple wireless communication standards, simultaneous broadcasting of SSIDs for different standards can cause user confusion and erroneous operations during connection.
Innovation Solution
Implementing a control mechanism to selectively broadcast the SSID of one access point while inhibiting the SSID of the other, based on the priority setting of the wireless communication mode selected by the user.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If SSIDs for both conventional wireless standard and 11ah standard are simultaneously broadcast, then connection processing is facilitated, but user confusion increases and erroneous operations occur
Solution Approach 1:
The patent segments the SSID broadcast by separating conventional wireless standard SSIDs from 11ah standard SSIDs. The control unit selectively broadcasts only the SSID corresponding to the currently active communication standard, preventing users from seeing multiple SSIDs that could cause confusion. This segmentation resolves the contradiction by maintaining ease of connection while improving connection accuracy.
Solution Approach 2:
The patent implements dynamic SSID broadcast control where the control unit determines which SSID to broadcast based on the current communication standard state. When switching between conventional wireless standard and 11ah standard modes, the system dynamically adjusts which SSID is broadcast, ensuring only the relevant SSID is displayed to users at any given time, thus preventing erroneous operations.
2Adaptability or versatility
If multiple wireless communication standards are supported, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by integrating multiple wireless communication standards (conventional wireless standard and 11ah standard) into a single image forming apparatus. The apparatus is designed to support both standards simultaneously with separate communication units, enabling it to adapt to different wireless environments while managing complexity through structured multi-functionality.
Solution Approach 2:
The patent applies local quality by assigning distinct characteristics to different communication units - the first communication unit is specialized for conventional wireless standard with lower speed but broader compatibility, while the second communication unit is specialized for 11ah standard with higher speed. This differentiation allows the system to manage complexity by giving each module its specific optimal properties.

AI summary
An information processing apparatus capable of reducing an erroneous operation when wireless communication is performed. The information processing apparatus includes a first communication unit that performs wireless communication with a first access point for a first wireless communication method compliant with IEEE 802.11ah, a second communication unit that performs wireless communication with a second access point for a second wireless communication method capable of performing communication at a higher speed than the first wireless communication method, and a controller capable of performing control, in a state in which the first access point and the second access point have been started such that wireless communication can be performed, such that a service set identifier (SSID) of one access point of the first access point and the second access point is broadcast, and an SSID of the other access point is inhibited from being broadcast.
