Bittium Tough SDR Handheld™

Advanced software-defined 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.

The Tough SDR radios provide a uniquely wide range of frequencies, 30-2500 MHz without gaps, across several frequency bands. Together with flexible configuration options and routing networks, even thousands of radios in one network are supported.

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.

Frequency Agility

Uniquely wide frequency range, 30-2500 MHz without gaps, 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

Highly Secure

Access to information security implementation and certification both nationally and internationally. Secure management for devices

Connectivity Across the Battlefield

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

With the Tough SDR radios, TAC WIN system and related waveforms, it is possible to bring broadband data, voice, and video to all mobile troops starting from brigade level and to dismounted soldiers and from sensor to shooter without bottlenecks.

The networks and nodes can be managed with Bittium Tactical Network Management™. 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.

Seamless Interoperability


Bittium TAC WIN Waveform
  • High-data-rate
  • Frequency hopping, adaptive modulation, MANET routing
  • Independent from GNSS using Bittium Air Interface Synchronization (AIS)
  • Optimized interference cancellation algorithms
  • Supported bandwidths: 5 / 10 / 20 MHz
  • QoS based network radio resource management
  • Supports a large number of network subscribers. Up to 100 simultaneous nodes in the same 2-hop wireless MANET network. Up to 1000 active nodes in the wired and wireless IP network.
Bittium Narrowband Waveform

  • CNR waveform operating in VHF and UHF bands from 30 to 512 MHz with 50 kHz channel bandwidth
  • No practical limit for number of nodes in the network
  • Node mobility up to 130 km/h
  • Frequency hopping
  • COMSEC (AES256) for voice and data, TRANSEC to protect all radio transmissions including signaling
ESSOR High Data Rate Waveform

In addition to the Bittium's proprietary waveforms, Bittium provides the ESSOR High Data Rate Waveform (EHDRWF) with Bittium Tough SDR radios. ESSOR High Data Rate Waveform is NATO STANAG 5651.

Bittium is a founding member in the a4ESSOR consortium that is responsible for the development of the ESSOR waveforms in the ESSOR program. 

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 in Tough SDR)
  • 1,25 MHz bandwidth, frequency hopping, frequency diversity (automatic establishment of parallel communications on different frequency channels)


ESSOR, the European Secure Software Defined Radio Programme, is managed by OCCAR on behalf of Finland, France, Germany, Italy, Poland, and Spain. The ESSOR High Data Rata Waveform (HDRWF) is the most mature product in the ESSOR Programme’s portfolio. This encompasses two ground-centric waveforms (EHDRWF and ENBWF), one air-ground-air waveform (E3DWF), a feasibility study for a SATCOM waveform (ESATWF) and propaedeutic engineering activities for the development of a new generation Multifunctional Information Distribution System (ESSOR MIDS) for a tactical data link based on ESSOR architecture. The ESSOR Programme is co-funded by the European Commission through the EDIDP initiative.
