Multi-Protocol Audio Relay for DECT Emergency Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current DECT technology struggles to relay calls or audio from communication devices using different protocols, such as cell phones or Land Mobile Radio, to DECT devices, causing difficulties and delays in emergency communication scenarios.
Innovation Solution
A communication device that supports multiple protocols, including DECT, LMR, cellular, Bluetooth, and Wi-Fi, is equipped with processing circuitry to transfer audio between devices using different protocols, allowing seamless communication across protocol boundaries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a DECT communication device is used to communicate with first responders, then reliable audio communication among first responders is achieved, but calls and audio from devices using other protocols (cellular, LMR) cannot be relayed to DECT devices
Solution Approach 1:
The DECT communication device is enhanced with multi-protocol support, enabling it to function not only with DECT devices but also with cellular and LMR devices. The device includes protocol identification circuitry that detects the protocol type of incoming calls and routing circuitry that directs these calls to appropriate DECT devices, making the system universally compatible across multiple communication protocols while maintaining reliable audio communication.
Solution Approach 2:
The DECT communication device acts as an intermediary between devices using different protocols. It receives calls from cellular or LMR devices, identifies the protocol type, and relays these calls to DECT devices used by first responders. This intermediary function enables seamless cross-protocol communication without requiring direct compatibility between all device pairs.
2Adaptability or versatility
If multiple communication protocols are supported in a DECT device, then protocol compatibility and audio relay capability are improved, but device complexity increases
Solution Approach 1:
The multi-protocol communication device is divided into distinct functional modules: protocol identification circuitry that detects the protocol type of incoming calls, routing circuitry that determines the destination DECT device, and audio relay circuitry that transfers the audio stream. This segmentation allows each module to perform its specific function independently, making the overall complex system manageable and maintainable.

AI summary
A first communication device of a plurality of communication devices is described. Each one of the plurality of communication devices other than the first communication device supports at least audio communication at least with the first communication device using at least one of a first communication protocol and a second communication protocol. The first communication device supports the at least audio communication using at least the first communication protocol and the second communication protocol, where the first and second communication protocols are different. The first communication device includes processing circuitry that causes the first communication device to transfer audio one of from a second communication device using the second communication protocol to a third communication device using the first communication protocol and from the third communication device using the first communication protocol to the second communication device using the second communication protocol.
