CPX BST250 Base Station

The CPX Wireless Intercommunication System is built on Axnes’ next‑generation technology platform and engineered for mission‑critical aviation operations and passenger transport. Designed to elevate both full‑duplex crew communication and Passenger Address (PA) capabilities, CPX delivers certified performance, high speech intelligibility, improved comfort, and seamless integration within today’s advanced aircraft cabins. Leveraging more than 30 years of Axnes wireless innovation, the CPX system combines proven ruggedness with cutting‑edge digital technology.

The BST250 distinguishes itself through its compact form factor, making installation effortless even in space‑constrained aircraft environments. It delivers dual‑zone wireless coverage, ensuring reliable communication throughout the cabin and mission areas.

Engineered for flexibility, the BST250 integrates seamlessly with wired intercom systems, PA systems, and external radios – or operates entirely standalone to create a robust wireless communication bubble. Third-party integrations across a broad range of digital protocols could be implemented based on customer interest. Fully EASA certified, it provides operators with trusted, aviation‑grade compliance.
