Tactical Waveforms

Portfolio for even the most demanding national and coalition use cases

Security & Reliability for Tactical Communications

In tactical communications with Bittium's software-defined radio -based (SDR) products and systems, including Bittium Tactical Wireless IP Network™ (TAC WIN) and Bittium Tough SDR™ tactical radios, the waveforms are at the core of the high-level data performance, security and reliability of the network.

Bittium's expertise in waveform development stems from long-term research and experience in radio technology, as well as cooperation with the Finnish Defence Forces, universities, research laboratories and industry since the 1990s.

Currently Bittium's waveform portfolio includes the following: Bittium TAC WIN Waveform™ and Bittium Narrowband Waveform™

In addition to Bittium's proprietary waveforms, Bittium provides the ESSOR High Data Rate Waveform (HDRWF) with the Bittium Tough SDR radios. The ESSOR HDRWF is NATO STANAG 5651. Bittium is a founding member in the a4ESSOR consortium that develops and provides the ESSOR waveforms.

High-Data-Rate Waveform for High Performance Mobile Backbone Network and Tactical Radios

Bittium TAC WIN Waveform™ for Bittium Tactical Wireless IP Network™ (TAC WIN) system, as well as for Bittium Tough SDR Handheld™ and Bittium Tough SDR Vehicular™ radios

Key features

  • 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

Narrowband Data and Communications for Soldiers and Vehicles

Bittium Narrowband Waveform™ for Bittium Tough SDR Handheld™ and Bittium Tough SDR Vehicular™ radios.

Key features

  • CNR waveform operating in VHF and UHF bands from 30 to 512 MHz with 50 kHz 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

Broadband Data Transfer and Communications for Coalition Troops

ESSOR High Data Rate Waveform (HDRWF) is NATO STANAG 5651 and compatible with Bittium Tough SDR Handheld™ and Bittium Tough SDR Vehicular™ radios.

ESSOR HDRWF enables broadband data transfer, cooperation and direct communications between coalition 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 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.


a4ESSOR SAS is a joint venture under French law made up of six leading European companies: Bittium (Finland), Indra (Spain), Leonardo Spa (Italy), Radmor SA (Poland), Rohde & Schwarz GmbH & Co. KG (Germany) and Thales (France). The company is responsible for the management of industrial activities within the framework of the ESSOR (European Secure SOftware defined Radio) program - awarded by OCCAR-EA - and for the coordination of partner activities.
