APPI-Technology is a French designer and manufacturer of wireless, hands-free communication solutions. Our technology improves the safety of teams working in hostile, noisy or confined environments where communication needs to be fast, clear, and without unnecessary limitations (like pushing a button to speak). Our APPI (Active Protection Personal Instrument™) communication systems allow for unlimited users and are developed with patented technology, including SyncAll (meaning no base, nor master radio) and Safeline (know who is connected in real time). Our Full-Duplex radios are long-range (up to 4Km), with powerful obstacle penetration, and hands-free. Using our solutions, teams are able to hold natural, clear conversations over a stand-alone network, and even relay to other networks (GSM, Talkies, etc.). Our product range includes headset radios with built-in hearing protection (APPI-CovR) and radios that are compatible with any protection equipment (APPI-Com).<
