Relaying Device Audio Signal Mixing for Transceiver Communication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication systems, multiple transceivers under the control of a relaying device cannot directly communicate with each other due to different transmission and reception frequencies, preventing other transceivers from hearing response sounds from a transceiver that has responded to a network call.
Innovation Solution
A relaying device with a wireless apparatus interface, signal processing unit, network interface, and packet processing unit, along with a mixing unit that combines uplink and downlink audio signals, allowing the relaying device to transmit and receive audio signals across multiple communication paths, including both analog and digital interfaces, enabling communication between half-duplex and full-duplex transceivers.

Engineering Contradiction Analysis
1Reliability
If transmission and reception are performed on different frequencies in communication between a transceiver and a repeater, then wireless communication can be established, but multiple transceivers cannot directly communicate with each other and response sounds cannot be heard through other transceivers
Solution Approach 1:
The relaying device acts as an intermediary that receives audio signals from one transceiver, processes them through the mixing unit, and transmits them to other transceivers. This mediator approach enables indirect communication between transceivers that cannot directly communicate on different frequencies, allowing response sounds to be heard through other transceivers while maintaining the frequency separation required for reliable wireless communication.
Solution Approach 2:
The mixing unit combines audio signals from multiple sources (network interface and wireless apparatus interface) into a unified audio stream. This merging of signal paths enables multiple transceivers to share the same communication channel through the relaying device, allowing them to hear each other's responses despite operating on different transmission and reception frequencies.
2Adaptability or versatility
If a mixing unit is added to combine uplink and downlink audio signals, then multiple transceivers can hear response sounds, but device complexity increases
Solution Approach 1:
The mixing unit is designed with multi-functionality to handle both uplink and downlink audio signals from different interfaces (network and wireless). By creating a universal audio processing component that can handle multiple signal types and sources, the patent reduces the need for separate dedicated processing paths, thereby managing device complexity while achieving the desired audio mixing capability across multiple transceivers.

AI summary
[Problem] To enable the response audio signal of one transceiver to be heard by other transceivers, in cases when a plurality of subordinate transceivers (wireless handset) are present.[Solution] A relaying device is provided with: a wireless apparatus interface having a repeater connected thereto; a signal processing unit connected to the wireless apparatus interface; a network interface connected to a network; a packet processing unit connected to the network interface; and a mixing unit provided between the signal processing unit and the packet processing unit. The packet processing unit reads out an audio signal from a packet inputted from the network interface, and outputs the audio signal as a downlink audio signal. The mixing unit inputs the downlink audio signal into the signal processing unit, and inputs an uplink audio signal into the signal processing unit. The signal processing unit outputs, to the wireless apparatus interface, the downlink audio signal and the uplink audio signal.
