Bridging two-way radios and telephones

Prelude

There has been a massive fire incident in the middle of town, and all of your team members are occupied on other floors. Feeling exhausted and on the verge of taking a quick break, you hear the cry of a baby coming from behind a door. With an axe in hand, you cautiously open the door and are horrified to witness a raging, untamed fire before you. Your determination to save the baby overrides all else, even if it means breaking a security policy. You have always been a rule-abiding individual, aware of the benefits that compliance brings. However, this situation is different—it’s a matter of life and death. You need to inform your fire chief that you’re going in. Suddenly, you realize that your phone is not with you; you only have your two-way radios.

Introduction

This project enables communication between two-way radios and telephones, facilitating crucial communication for firefighters and policemen in various scenarios such as battlefields or firefighting situations. It allows them to connect their two-way radios to office telephones, enabling direct communication with the headquarters. During my time at FD Eshragh, I developed the necessary code to implement this functionality as part of a larger system that encompassed numerous other features.

Illustration of the system

The following demonstrates how officers and firefighters utilize the system.

The depicted scenes illustrate how operational details can be seamlessly transferred to the headquarters, keeping them informed by bridging telephone and radio communications.
