Bittium Corporation Media Release June 6, 2024, 9:00 a.m. (CEST +1)

The Ministry of Defense of the Republic of Croatia has adopted the Bittium Tactical Wireless IP Network™ (TAC WIN) software-defined radio-based system and the Bittium Tough SDR Vehicular™ radio as tactical communication solutions for the armed forces of the Croatian Armed Forces. The adoption follows a several-year phase-out of the products by the Croatian Navy. The implementation phase was carried out in cooperation with Bittium’s Croatian partner IntellByte INFO, an IT solutions provider that acts as an integrator of the Croatian Navy Tactical Communication System Unit as well as a contracting party with the Navy. The orders related to this collaboration received during the implementation phase, as well as those expected in the future, do not have a significant impact on Bittium’s financial guidance for 2024, nor on the achievement of its long-term goals.

During the deployment phase, part of the Croatian Navy’s support communication network was built with the TAC WIN modular and broadband system and Tough SDR Vehicular radios were used to link Navy ships as part of the survivable tactical support network.

Based on the successful deployment, the Ministry of Defense of the Republic of Croatia adopted Bittium’s TAC WIN system and Tough SDR Vehicular radios for service with the Croatian Armed Forces. In addition to the Navy, the products can also be offered to other branches of the Croatian Armed Forces. The deployment of the Tactical Communications Network for the Croatian Armed Forces will be phased and the Armed Forces will issue possible separate purchase orders for Bittium’s products and solutions as the deployment progresses.

“The successful deployment of the TAC WIN system and Tough SDR Vehicular radios by the fleet and acceptance into service by the Croatian Armed Forces is an excellent demonstration of the performance and applicability of our products and systems for various use cases.” The TAC WIN modular software-defined radio-based system works seamlessly with other systems in use. We are proud to offer our products and systems to all branches of the Croatian Armed Forces together with our local partner IntellByte INFO. Together, we can bring the tactical communications of the Croatian Armed Forces into a new era,” says Tommy Kangas, senior vice president of Bittium’s defense and security business segment.

“Situational awareness, rapid movement, and the ability to make quick decisions are the key elements of modern warfare doctrine. In order to achieve these goals, the modernization of tactical communications has been set as an imperative for the development of the Croatian Armed Forces. Bittium’s solutions have significantly increased productivity and brought a new and improved operational experience to the Croatian Armed Forces. It was a visible technological leap in ICT, both for us, who implemented Bittium solutions, and for the Croatian Armed Forces, who got the opportunity to use broadband technologies. locally, but also globally by deploying intercommunication services that enable communication between military coalition troops,” says Jasmin Hodzic, CTO of IntellByte INFO.

Bittium Tactical Wireless IP Network™

The Bittium Tactical Wireless IP Network (TAC WIN) is a Software Defined Radio (SDR) based wireless broadband network system designed for military and public safety. With the MANET (mobile ad hoc network) system, links and interconnect networks can be quickly formed into one logical IP network regardless of location. Bittium TAC WIN is compatible with existing fixed and wireless network infrastructures. The core of the system is a tactical router that allows users to freely form both wired and wireless broadband IP data connections. The tactical router also allows connections to different types of terminals and other communication systems to connect them into a single communication network. In addition to the router, the system consists of three types of radio heads, each radio head covering its own frequency band and can be used to flexibly form optimized network topologies for different communication needs. All system products are designed for harsh environments, and thanks to the system’s automated features, system deployment is quick. Thanks to the software-based functionality of the Bittium TAC WIN system, it can be easily updated with additional performance, allowing it to be developed and maintained cost-effectively throughout the system’s lifetime.

Bittium Tough SDR™ family of products

The Bittium Tough SDR tactical radio product family consists of the Bittium Tough SDR Handheld™, a tactical handheld radio for individual soldiers, and the Bittium Tough SDR Vehicular™, a tactical radio for vehicle installations. Tough SDR radios help create and share real-time situational information at all levels of the organization. This improves the productivity and efficiency of tactical troops, and leading troops is easier based on up-to-date situational information and more reliable communications. The radios’ uniquely wide range of frequency bands improves survivability in combat. Using multiple waveforms, even simultaneously, improves compatibility and enables operations at different levels and missions. The radios are compatible with the NATO-standardized ESSOR High Data Rate Waveform, which enables tactical communication between troops of different nations. Together with the software-defined radio-based Bittium Tactical Wireless IP Network™ (TAC WIN) system used to form a broadband mobile IP backbone network, it is possible to carry broadband data and voice to all mobile troops on the battlefield.
