CHALLENGE: Mobile PTT solutions are critically dependent on the right accessories to complete the voice communication solution.

Swiss Federal Railways (SBB) is modernizing communication methods for its field workforce based on cellular Push-to-Talk (PTT). A critical enabler for this next-generation solution has been a suitable handheld PTT device with short latency, good audio, and the possibility to send audio signals according to predefined functionalities. After a comprehensive evaluation, SBB selected the Aina PTT Voice Responder as the ideal handheld device for their cellular PTT solution. 


Aina PTT Voice Responder is a next-generation Bluetooth remote speaker-microphone (RSM) for cellular PTT solutions. It operates with Android and iOS smart devices and is compatible with a wide variety of different PTT software applications. Aina PTT Voice Responder has loud and clear high-quality audio, is highly durable and designed for very demanding working conditions, and supports all the important professional PTT communication features. 

Aina PTT Voice Responder is provided to SBB in Switzerland together with Aina PTT’s reliable partner, Rhäticom AG. SBB operates in mission-critical fields where every second counts. Seamless communication among rail workers is significant. With the introduction of the AINA PTT Voice Responder, SBB can ensure that all communication is delivered instantly without delays. The audio quality meets the requirements even in the most challenging, noisy situations. 

The project is entering the field piloting stage. AINA PTT is proud to be part of this critical communication system. Thank you for choosing AINA PTT!
