Bittium Tough SDR Handheld™

Advanced tactical radio for dismounted soldiers.

Next-Generation Tactical Handheld Radio

Bittium Tough SDR Handheld™ is a next-generation software defined tactical radio for dismounted soldiers, such as squad or platoon leader. With the radio it is possible to bring broadband data transfer and voice to mobile troops across the battlefield. This improves the performance and the effectiveness of the tactical troops, and leading the troops is easier based on the up-to-date situational awareness and more reliable connections. 

With Bittium Tough SDR Handheld troops can communicate securely over narrowband and wideband waveforms. The radio can flexibly use the best performing waveform considering the conditions and the mission. The uniquely wide range of frequency bands in the radios improves combat survivability. Using several waveforms improves compatibility and enables operations on different levels and missions. Also legacy and national proprietary waveforms can be seamlessly ported to the radio with national COMSEC and TRANSEC.

The Tough SDR radios provide a uniquely wide frequency range, 30-2500 MHz, across several frequency bands. Together with flexible configuration options and routing networks, even thousands of radios in one network are supported.

Uniquely wide frequency range 30-2500 MHz provides frequency agility and less interference

Support for Different Waveforms

Support for several different waveforms with seamless porting also for legacy and national proprietary waveforms

Easy Operation

Best-in-class user interface and usability for easy operation

Several Routing Networks

Support for several routing networks and even thousands of radios in one network

Flexible Integration of Applications

Application sandbox for flexible integration of C2 applications, such as BMS and blue force tracking


Access to information security implementation and certification both nationally and internationally

Next-Generation Tactical Handheld Radio

Connectivity Across the Battlefield

The Handheld radio is compatible with Bittium Tough SDR Vehicular™ and Bittium Tactical Wireless IP Network™ (TAC WIN) system.

With the Tough SDR radios, TAC WIN system and related waveforms, it is possible to bring broadband data and voice to all mobile troops starting from brigade level and all the way across the battlefield.

The networks and nodes can be managed with Bittium Tactical Network Management System™. The intuitive and visual toolset is used for network planning, real-time management of the networks, and performance analysis based on big data collected from the network.



Open/close section Bittium TAC WIN Waveform™

Open/close section ESSOR High Data Rate Waveform

In addition to the Bittium's proprietary waveforms, Bittium is a National Champion in the ESSOR program. 

ESSOR High Data Rate Waveform enables broadband data transfer, cooperation and direct communications also between different national troops in international joint operations, starting already from the patrol level.

Key features

  • Enables broadband data transfer, cooperation and direct communications between different national troops in coalition operations starting already from the patrol level
  • Interoperable, secure, MANET radio transmission network
  • Frequency range 225-400 MHz (extensible)
  • 1,25 MHz bandwidth, frequency hopping, frequency diversity (automatic establishment of parallel communications on different frequency channels)


The aim of the ESSOR program is to develop the European Software Defined Radio technology in order to improve the capabilities for cooperation in coalition operations. The first phase of the programme was successfully completed in 2015. In addition to the European High Data Rate Waveform, the first phase of the program produced and validated the definition for the European Software Defined Radio Architecture which was ported and qualified on six different European platforms. The following ESSOR OC1 phase aims to enhance the operational capabilities of the ESSOR High Data Rate Waveform (HDR WF), developed in the previous phase of the ESSOR programme, in order to meet the most demanding requirements of the battlefield with secure, high capacity land tactical communications.
