ADB-720-RPU Digital Encryption Modules (Wire-in option board for RELM RPU3300U Portable and Mobile radios – or other projects)
ADB-720-RPU Crypto Level II Digital Modules – 32 bit Key
The ADB-720-RPU is designed for simple wire-in installation into the RELM RPU3300 series VHF/UHF portable radios.
The ADB-720-RPU series digital encryption module for two-way radios uses advanced digital encryption to provide high level protection (Class II) of radio communications traffic from eavesdropping by unwanted listeners and the most determined adversaries. It uses a highly secure AES encryption algorithm with over four billion key combinations to provide discreet and confidential communications. The ADB-720-RPU module is a cost-effective solution for high-end voice encryption for portable and mobile radios used by commercial entities, police departments, public safety organizations, and militaries as a defense against unauthorized interception of private and sensitive voice transmissions by casual eavesdroppers or the most determined listeners that may be a threat to property or life.
The ADB-720-RPU series module ensures that sensitive communications are safe and secure, utilizing a sophisticated encryption algorithm to thwart attacks on private communications. When an eavesdropper attempts to listen to an encrypted conversation, the speech transmission will not be heard at all. There will be no vocalization; instead the unwanted listener will hear only “white noise”. Digitization of the sender’s speech also ensures that the encrypted voice transmission will be clear and easy to understand, which is often vital in emergency situations and military operations.
By using a digital communication channel within a radio communication system, the ADB-720-RPU is able to reject background noise, further enhancing speech quality during chaotic or mission critical operations.
The ADB-820-RPU voice security module installs easily into Relm VHF/UHF mobile and portable radios.
Programming of the module is performed easily via a personal computer (PC). The ADB-720-RPU digital encryption module provides for high level voice security in radio systems utilizing conventional analog repeaters in the 12.5/25 kHz radio spectrum. It can be used in Simulcast, LTR, and voting systems, as well as dispatch systems that offer Check, PTT-ID, OTAR, and GPS location information.
The ADB-720-RPU module offers a programmable “autodetect” option, enabling automatic receive operation while the radio is operated in secure mode. Other optional capabilities include compatibility with frequency inverters using analog keys and compatibility with double-inversion voice band scramblers using analog keys.
Additionally, these modules have a very unique feature that would allow with our technical guidance the end user to apply their own algorithm. Enabling this product to be customer specific
