The R-460AM, the newest radio relay offered by Transbit, was presented at the company’s booth in Kielce. This modern digital device, which received the Defender award at this year’s MSPO, is a component of the Digital Transmission Communications Shelter (AŁC-T) and the Mobile Communication Centers (MCC1) for the Wisła and Narew air and missile defense systems.
Within the MCC1 systems, the radio relay has been integrated with the IBCS air and missile defense command-and-control system. It is worth noting that the R-460AM is the first non-U.S. radio-communication device incorporated into IBCS. As a result, the Air Defense Forces of the Polish Armed Forces have their own independent communications system. In the above-mentioned programs, Transbit serves as the integrator of communications systems and the entire ICT architecture.
The R-460AM radio relay also received a distinction from the Operational Commander of the Armed Forces Branches, Lt. Gen. Maciej Klisz, in the Cyber Domain category, as well as an award in the prestigious 2025 National Security Leader competition organized by the Association of Suppliers for Uniformed Services in Bydgoszcz.
The R-460AM-2 radio relay was recognized as a significant achievement in the area of Polish communications equipment and for its integration with the IBCS command-and-control system within the Wisła and Narew programs. The award confirms our contribution to the development of technologies for the security and defense of the Republic of Poland. It is a remarkable acknowledgment of innovative Polish communications solutions that strengthen the security and operational capabilities of the Polish Armed Forces.
The radio relay is an example of a modern tactical software-defined radio (SDR), enabling the use of various waveforms. It offers high throughput, about 700 Mb/s in both directions, both receiving and transmitting. A new feature is its integration with the TS-01 real-time server, also developed by Transbit, a solution that has already been validated under field conditions. Having its own real-time source enables time synchronization across individual elements of the air-defense system, radars, launchers, and command posts, making the system independent of issues related to disruptions of GPS-provided time signals.
Another innovative feature introduced in the R-460AM radio relay is the ability to assign channel priorities and allocate them to specific tasks—for example, dedicating one channel to the real-time server or to transmitting information to a command post.
The device is also characterized by very easy configuration, the process has been fully automated. Operating parameters can be set either from the commander’s computer or through the management panel. Antenna alignment, optimizing their mutual positioning to achieve the best signal quality (and thus maximum transmission speed and connection stability), is also performed automatically.
The R-460AM-2 radio relay provides full compatibility with the communications systems used by the Polish Armed Forces. It includes two modules: the R-460A RFU-III, operating in Band III, which ensures compatibility with commonly used RWŁC-10/T communication nodes; and the R-460A RFU-IV, operating in Band IV, intended for cooperation with the latest AŁC-T digital-transmission communications shelters. By incorporating the newest NATO standards, the radio relay also guarantees interoperability with the communications assets of other Alliance members.
