Overview of Push To Talk (PTT) Solution
The Push To Talk (PTT) solution is an emergency call system designed for office spaces. It is a wall-mounted, battery-operated unit that enables quick and reliable communication with emergency services such as the police, fire service, or maintenance department.

Background and Purpose
Current emergency calling devices in office environments face several limitations:

They are dependent on power supply and Voice over Internet Protocol (VoIP) systems, which can fail during power outages or network issues.
Companies often lack visibility into the operational status of these devices, which can result in employees being at high risk during emergencies if the devices are not functioning properly.
The PTT solution addresses these shortcomings by offering a more reliable, self-sufficient emergency communication system.

Technical Details
Hardware Components:

Push Buttons: Three buttons designated for different emergency services.
Connectivity Board: A custom-developed board that facilitates communication.
Modem: A Quectel modem for network connectivity.
Battery: Ensures the device remains operational even during power outages.
Microphone and Speaker: For clear audio communication.
Microcontroller: Manages the device’s operations and connectivity.
Software:

Developed using React and C++ to ensure robust performance.
Connectivity:

Supports 4G and 2G Circuit Switched Fallback (CSFB) for reliable network connections.
Solution Description
The PTT device uses cellular technology to ensure a stable and reliable connection, even when traditional power and network systems fail. Key features include:

Battery Monitoring: The device constantly monitors its battery level to ensure it is always ready for use.
Network Status Monitoring: Continuously checks network availability and quality.
Emergency Buttons: Three push buttons allow users to call specific emergency services directly.
Modem Functionality: The modem actively searches for the best available connection to ensure successful communication.
Application Opportunities
The PTT solution is highly versatile and can be deployed in various settings:

Office Buildings: Ensures employee safety on every floor by providing immediate access to emergency services.
Public Places: Useful in locations that require constant maintenance and where quick communication with emergency services is crucial.
Hazardous Environments: Suitable for areas where mobile phones are not permitted, but emergency communication is necessary.
Project Timeline
04/22: Start of the project, with the initial design of the audio circuit.
05/22 - 08/22: Testing of the first Printed Circuit Board (PCB) for audio functionality and official review of the audio circuit from Quectel.
09/22: Designing the second version of the audio circuit, integrating it, and completing the 3D design.
Ongoing Tasks: Further testing and integration based on initial results and feedback.
Future Development
The current status of the PTT solution is a Proof of Concept (PoC), and efforts are underway to secure funding for productization. The estimated timeline for patent completion is 2 to 4 years.
