R-460AM-2 Radio Relay manufactured by Transbit play a fundamental role in ensuring a modern and reliable communication of the Air Defense and Command and Communications Forces

The R-460AM-2 Digital Radio Relay is a key communication device in the Polish Armed Forces. Its predecessor, the R-450A version, was delivered to the Polish Armed Forces in the hundreds, forming an independent military communication network. The radio relay is used to build long-range communication nodes.

The R-460AM-2 was developed as a High Capacity Line of Sight (HCLOS) radio relay, enabling stable and broadband point-to-point and point-to-multipoint connections in demanding operational conditions. The device operates in the extended Band III and Band IV frequency ranges, significantly increasing its application flexibility. R-450C-01 is part of the latest generation of systems based on Software Defined Radio (SDR) architecture, allowing software-based definition of transmission parameters, including modulation and operating modes. It is equipped with advanced transmission protection algorithms that ensure resistance to jamming and safeguard against data interception.

Notably, the R-460AM (the version operating exclusively in Band IV) has been approved for integration with the American Integrated Battle Command System (IBCS), making it the only non-American communication asset to receive such accreditation. The R-460AM-2 was designed as a modular and easily configurable solution, consisting of three main components:

R-460A-RFU-IV – radio unit for Band IV
R-460A-RFU-III – radio unit for extended Band III+
R-460A-BBU – control unit (Baseband Unit)

Operation in NATO frequency bands III+ and IV

Compatibility with the digital radio relay systems of the R-450A family previously used by the Polish Armed Forces

Integration with the IBCS air defense C2 system

Operating range from several kilometers up to 50 km

Data transfer in band IV – 600 Mbps in duplex mode with dual-channel transmission using MIMO antennas

Data transfer in band III+ – 100 Mbps in duplex mode

Compatible with Switched Beam and MIMO antennas

Advanced data transmission algorithms, resistant to jamming and data interception

R-460A Radio Relay Variants – Configuration Flexibility Depending on Application

The R-460A radio relay has been designed as a modular and scalable digital communication platform, available in several functional versions. This allows hardware configurations to be tailored to specific tasks – from simple access connections to fully functional network nodes with high throughput and operational resilience.

R-460S – Lightweight Access Variant:
Configuration: RFU-IV radio unit only, without the BBU (control unit)
Operating Band: IV
Throughput: up to 600 Mb/s full duplex
Functionality: limited – functions as an access terminal, can be operated by a small group of soldiers
Application: rapid integration of a single unit (e.g., platoon or patrol) into a larger tactical network. A lightweight, simple, and quick-to-deploy variant enabling rapid network range extension without a full management suite. Ideal for integration with mechanized infantry or observation posts.

R-460AM – Standard Full-Function Set for Band IV:
Configuration: RFU-IV + BBU (control unit)
Operating Band: IV
Throughput: up to 600 Mb/s full duplex
Functionality: full – includes link management and transmission control
Application: classic point-to-point connections, e.g., between command containers. A reliable set for building high-performance tactical communication links – the backbone of modern IP infrastructure at the battalion, brigade, or fire control post level.

R-460AM – Variant Supporting MIMO Antennas, Maximum Throughput in Band IV:
Configuration: RFU-IV + BBU with extended functionality
Operating Band: IV
Throughput: up to 600 Mb/s full duplex (with MIMO antenna)
Functionality: full, including support for advanced transmission techniques
Application: high-capacity connections, such as ISR data transmission, UAV video streaming, or real-time video feeds. A solution for units requiring stable, broadband, and secure data transmission – suitable for mobile communication nodes, stationary command posts, observation, or reconnaissance systems.

R-460AM-2 – Full Functionality, Support for Bands III+ and IV, Backward Compatibility with R-450A:
Configuration: RFU-IV + RFU-III + BBU
Operating Bands: IV and extended III+
Throughput:
- up to 600 Mb/s in Band IV (with MIMO antenna)
- up to 100 Mb/s in Band III+
Functionality: Full – dynamic band selection and compatibility with previous generations
Application: Bridging technology gaps during modernization of the Polish Armed Forces; operation in mixed environments (new and legacy equipment)

The most versatile variant, enabling:
- Deployment in next-generation Mobile Digital Communication Nodes
- Step-by-step equipment upgrades without decommissioning existing infrastructure
- Full compatibility with R-450A radio relays (e.g., in Band III+)
- Maximum operational flexibility – frequency band selection depending on environmental conditions or electronic warfare threats

Key Benefits for the Polish Armed Forces:

Ensures operational continuity and easy expansion of tactical networks
Enables gradual modernization without costly decommissioning of legacy systems
One platform, many use cases – from lightweight terminals to high-throughput backbone radio relays

The R-460AM-2 radio relay is an advanced digital device designed to establish fast, secure, and resilient wireless point-to-point and point-to-multipoint connections within military frequency bands. The system was developed to meet the demands of the modern battlefield, where reliable, high-capacity data transmission is a key element of effective command and operational response.
The R-460AM-2 radio relay is used wherever there is a need for rapid deployment of a dependable, broadband transmission link, including:

Connecting command posts at various levels (e.g., containers, command vehicles)
Integration with ISR systems, radars, sensors, and electronic warfare assets
Communication between mobile platforms – vehicles, containers, remote systems

The R-460AM-2 represents a modern, reliable, and field-proven solution for armed forces and tactical communication units that require broadband connectivity in dynamic and demanding operational environments.
