Terminal Apparatus Wireless Connection Verification via BLE and Wi-Fi
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Terminal apparatuses often fail to detect devices connected via an access point, preventing users from operating devices over a wireless LAN, as existing technologies lack effective verification mechanisms for wireless connections.
Innovation Solution
A terminal apparatus equipped with both Bluetooth Low Energy (BLE) and Wi-Fi communication units, which searches for and connects to access points, allowing it to verify device connections by displaying a list of available access points and facilitating the selection of the appropriate one for communication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal apparatus connects to an access point selected by the user, then the device can be connected to the wireless network, but the terminal apparatus may fail to detect the presence of the device via the access point
Solution Approach 1:
The terminal apparatus performs a verification process by searching for the device via the selected access point after connection. This feedback mechanism checks whether the device is actually detectable through the chosen access point, and if not, prompts the user to select a different access point, thereby ensuring reliable connection establishment.
Solution Approach 2:
Before finalizing the connection, the terminal apparatus preliminarily verifies whether the device can be detected via the selected access point by performing a search operation. This preliminary action prevents wasted connection attempts on access points that cannot facilitate device detection.
2Device complexity
If the terminal apparatus uses only Wi-Fi communication for wireless LAN connection, then the connection process is simple, but it cannot verify device presence effectively
Solution Approach 1:
The terminal apparatus merges Bluetooth Low Energy (BLE) communication capability with Wi-Fi communication. The BLE unit is used to detect the presence of the device via the access point, while Wi-Fi handles the actual data transmission. This combination enables effective connection verification without significantly increasing overall system complexity.
Solution Approach 2:
The terminal apparatus is equipped with multi-functional communication units that can operate in different modes: BLE for device detection and verification, and Wi-Fi for data communication. This multi-functionality allows a single device to perform multiple roles in the connection establishment process.

AI summary
A terminal apparatus includes a first wireless communication unit, a second wireless communication unit, and a controller. The first wireless communication unit conducts first wireless communication with a device under a first wireless communication scheme. The second wireless communication unit conducts second wireless communication via an access point. The controller causes a predetermined display unit to display a list of access points which the first wireless communication unit receives from the device. The device acquires the list by searching for the access points. The controller connects the device to an access point selected from the list under a second wireless communication scheme. The controller designates the access point selected from the list as an access point to which the second wireless communication unit is to connect, and causes the second wireless communication unit to search for the device via the access point selected from the list.
