Directional Wireless Voice Communication with Network Handoff
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication methods require local area or wide area networks to establish connections between devices, and there is no known method for initiating wireless communication with a nearby device using directional designation or sharing device identities after an initial connection.
Innovation Solution
A directionally oriented wireless telecommunications facility is used to create a bidirectional communication link using infrared or RF radiation, allowing devices to manually point and connect without network reliance, and subsequently switch to omnidirectional communication for continued connection, enabling the exchange of MINs, IP addresses, or MAC addresses for further network access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If directional infrared communication is used to initiate connection, then connection speed and precision are improved, but device complexity increases
Solution Approach 1:
The communication process is divided into two distinct phases: initial connection establishment using directional infrared communication, and subsequent data transmission using omnidirectional RF communication. This segmentation allows each subsystem to be optimized for its specific function, with the infrared subsystem handling only connection initiation and the RF subsystem handling data transmission, thereby reducing overall system complexity while maintaining fast connection establishment.
Solution Approach 2:
The directional infrared communication performs preliminary actions by establishing the connection and exchanging identification information before the main data transmission begins. This preliminary exchange of MINs, IP addresses, or MAC addresses through the simpler infrared channel prepares the devices for efficient omnidirectional RF communication, separating the complex authentication phase from the data transfer phase.
2Ease of operation
If omnidirectional RF communication is used for initial connection, then ease of operation is improved, but connection precision and security worsen
Solution Approach 1:
The directional infrared communication acts as an intermediary that bridges the gap between ease of operation and connection precision. It provides a focused, secure channel for exchanging identification information that verifies the intended communication partner before allowing omnidirectional RF communication to begin, thus maintaining both user-friendliness and identification accuracy.
3Reliability
If network infrastructure is required for wireless communication, then communication reliability is improved, but loss of time in network setup increases
Solution Approach 1:
The devices perform preliminary exchange of network identification information (MINs, IP addresses, MAC addresses) through the rapid directional infrared channel before actual data transmission begins. This preliminary action allows the devices to be pre-configured with each other's network identifiers, enabling immediate reliable communication without requiring time-consuming network setup or scanning procedures.

AI summary
A cellular telephone or similar wireless device possesses a directionally oriented wireless telecommunications facility to initiate and operate a second type of wireless connection. Optionally, the devices share mobile identification numbers (MINs), IP addresses, or MAC addresses. Also optionally, the devices create contacts in their contact databases reflecting the identity of the connection. By this means, a subsequent telephony-based or LAN-based connection may be instituted.
