In the industrial and public works sectors, workers often operate in confined, noisy, and hazardous environments. Traditional communication methods like talkie-walkies can fail in these conditions,  as background noise makes it difficult to hear, and limited space can restrict movement. Full-duplex wireless systems like the APPI-Com allow for clear, continuous two-way communication, enabling workers to exchange information without interference. This improves safety and coordination, ensuring that messages are received and responded to promptly, even in challenging conditions.
