EF-256 Embedded Functions for Secure Voice & Data

EF-256 Embedded Functions for Secure Voice & Data

The Secure Voice & Data Embedded Functions EF-256 are intended for integration into radio transceivers and other communication device. These embedded functions are suitable for commercial, industrial, governmental, security, paramilitary and even military communication systems. The Secure Voice & Data Embedded Functions brings high-end digital radio capabilities to any radio design.

The internal Vocoder digitizes the voice. The data is encrypted and converted to an in-band signal by the built-in high performance modem. The Vocoder dramatically improves voice quality in adverse channel conditions, extending the range of voice communications. Beyond-Line-Of-Site (BLOS) communication is vulnerable to eavesdropping due to the vast areas covered. Built-in AES encryption ensures that all digital voice and data communications are secured by a trusted algorithm. The lower data rates feature constant amplitude modulation, while higher rates require less RF power on an SSB transceiver (power control). The SDV function has AUTO DRC (Data Rate Change) capability.
