General information

TAKRAD is a personal radio for a modern-day soldier with a superior SDR architecture that allows reliable and secure data and voice communication.

TAKRAD is perfectly designed for military needs with its robust mechanical design and advanced electronics.

TAKRAD was created by combining the experience and tradition of RIZ PE, with youth and innovativeness of Impel. One would not think of Croatia as a leader in radio technology, but it is the birthplace of great Nikola Tesla, whose innovations greatly helped in development of radio. We are proud that TAKRAD brings back to mind this interesting fact.

Our technology based on software signal processing is a completely new chapter in the development of military radio devices that places TAKRAD on the world stage of radio communication devices.

Except for internal communication, thanks to integrated and exterior sensors (GPS, accelerometer, dosimeter, heart rate monitor etc.) TAKRAD offers detailed information on the location and physical condition of the soldier. TAKRAD also automatically recognizes dangerous situations (SOS – Man Down Alert) and reports them using a robust security channel.

Connection to an outside terminal for display of multimedia information (pictures, maps, locations, chat) is simple, and simultaneously secure and reliable thanks to the integrated Bluetooth Low Energy system.

SDR architecture in TAKRAD device enables easy customization for the required purpose. By using the narrowband and broadband mode, the device ensures simultaneous work of several work groups, creation of self-forming and self-healing ad-hoc mesh networks.

Exceptionally solid mechanical housing made of aluminum ensures reliable work in extreme conditions and compatibility with MIL STD 810 and IP 67. TAKRAD is a modern and long-term solution for C3 on tactical level. It is equipped with various telephone combinations, high capacity battery, various antennae and other accessories, depending on the user’s needs.

Innovative solutions and modern technology with which TAKRAD was developed ensure competitiveness, and therefore, are an advantage in comparison to the leaders in communication radio devices.

RIZ PE is a Croatian company with 70 years of tradition and is the project holder and a long-time partner of Ministry of Defense of the Republic of Croatia, as a Croatian manufacturer of military communication devices and systems.

Impel Group is a young company which directed its vision toward development and manufacture of innovative solutions in the area of radio communication electronics and embedded computer systems. This is an engineering team with many years of experience in implementing demanding projects that develop highly sophisticated devices custom-designed according to the needs of the client.

TAKRAD is the result of this synergy. This is a personal radio for a modern-day soldier with a superior SDR architecture that allows reliable and secure data and voice communication. TAKRAD is perfectly designed for military needs with its robust mechanical design and advanced electronics.
