The EF-256 Secure Voice & Data Embedded Functions are designed for integration into radio transceivers and other communication devices, catering to a wide range of applications including commercial, industrial, governmental, security, paramilitary, and military communication systems. These embedded functions bring high-end digital radio capabilities to both new and existing transceiver designs, allowing radio manufacturers to effectively secure communications.

Featuring an internal Vocoder that digitises the voice, the EF-256 significantly improves voice quality in adverse channel conditions and extends the range of voice communications. The built-in high-performance modem encrypts the data and converts it to an in-band signal.

For beyond-line-of-sight (BLOS) communication, which is particularly vulnerable to eavesdropping due to the vast areas covered, the EF-256 employs built-in AES encryption to ensure all digital voice and data communications are secured with a trusted algorithm. Additionally, its secure voice and data (SDV) function includes Auto Data Rate Change (DRC) capability, optimising performance by automatically selecting the best transmission data rate based on current channel conditions.

With its robust features ensuring secure and high-quality digital voice and data communications in challenging conditions, the EF-256 stands as an indispensable component for communication systems requiring reliable, long-distance communication.
