Bittium Tough SDR™ product family

Bittium Tough SDR Handheld is part of the new Bittium Tough SDR product family that consists of two advanced tactical radio products:


With the radios it is possible to bring broadband data transfer and voice to all mobile troops starting from brigade level and all the way across the battlefield. The products help to produce and share real time situational awareness (location, image, voice, video, and sensor data) to all levels of the organization.

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. 

The new product family and its products expand Bittium's product offering from Bittium Tactical Wireless IP Network™ (TAC WIN), used for forming a broadband tactical mobile IP backbone network, to individual soldier and vehicular level tactical radios. Both products are compatible with Bittium TAC WIN and the same waveform can be used with the Tough SDR radios. Read more about Bittium TAC WIN.

Bittium Tough SDR introduction

Bittium Tough SDR Handheld™

Bittium Tough SDR Handheld™ is a Software Defined Radio (SDR) based tactical handheld radio for individual soldiers, such as squad or platoon leader, providing a uniquely wide frequency range (30-2500MHz) across several frequency bands. Together with flexible configuration options and routing networks, it supports even thousands of radios in one network. 

Uniquely wide frequency range providing frequency agility and less interference

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

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

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

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

Utilizing latest mobile technologies




With Bittium Tough SDR Handheld troops can communicate securely over narrowband and wideband waveforms. Bittium Tough SDR Handheld can flexibly use the most appropriate waveform with the best fit with the conditions and the mission.

Also legacy and national proprietary waveforms can be seamlessly ported to the radio with national COMSEC and TRANSEC.




  • Bittium Narrowband Waveform™ enables transmitting and receiving voice and messages from command network reliably even with long communication ranges and in congested networks.
  • Bittium TAC WIN Waveform™ connects the user as a part of the tactical broadband network that enables transmitting calls, messages and data in real time throughout the whole network.
  • 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.



The uniquely wide range of frequency bands, 30-2500MHz, improves combat usability and enables using the same equipment in different geographical areas.

Using several waveforms improves compatibility and enables operations on different levels and missions.
