Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication devices can only communicate with each other through base stations, lacking direct communication capabilities even when in close proximity.
Innovation Solution
Incorporating a second short-range transceiver in wireless communication devices, operating under IEEE 802.11 standards, to enable direct peer-to-peer communication using ad hoc mode, allowing devices to detect and connect with each other without the need for a network access point, and using profile data for auto-initiated contact notifications based on matching user preferences.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wireless communication devices communicate through base stations, then network connectivity is maintained, but direct communication capability between nearby devices is lost
Solution Approach 1:
The wireless communication device integrates both conventional base station communication and direct peer-to-peer communication capabilities through a single device architecture. The device can operate in multiple communication modes (network mode and ad hoc mode) depending on the operational requirements, eliminating the need for separate devices for different communication functions.
Solution Approach 2:
The communication architecture is made dynamic by allowing the device to switch between different communication modes based on real-time needs. The system can transition from network-based communication to direct peer-to-peer communication when devices are in proximity, and vice versa, providing flexible adaptation to varying operational conditions.
2Ease of operation
If push-to-talk technology is used, then group communication appears direct, but actual communication still relays through base stations
Solution Approach 1:
The patent extracts the relay function from the communication path by implementing true peer-to-peer communication that bypasses the base station. When devices are in proximity, they can establish direct communication links, removing the intermediate relay step and providing transparent direct communication while maintaining the simplicity of push-to-talk operation.
3Adaptability or versatility
If short-range transceiver is added for direct communication, then peer-to-peer capability is enabled, but device complexity increases
Solution Approach 1:
The patent merges the conventional base station transceiver and the short-range peer-to-peer transceiver into a unified device architecture. Both transceiver systems share common components such as the processor, memory, and control mechanisms, allowing direct communication capability to be added without proportionally increasing overall device complexity.

AI summary
A wireless communication device includes conventional components to permit a network communication link to be established with a wireless communication network. In addition, the wireless communication device includes a non-network short-range transceiver that detects the presence of other similarly equipped devices. When two such equipped devices come within proximity of each other, a direct non-network wireless communication link is established.
