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 (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™
  • Bittium Narrowband Waveform™

In addition to Bittium's proprietary waveforms, Bittium provides the ESSOR High Data Rate Waveform (EHDRWF) with Bittium Tough SDR radios. Bittium is a founding member in the a4ESSOR consortium that is responsible for the development of the ESSOR waveforms in the ESSOR program

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



Bittium TAC WIN Waveform™ for Bittium Tactical Wireless IP Network™ (TAC WIN) system, 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. 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.

Narrowband Data and Communications for Soldiers and Vehicles


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

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 (EHDRWF) for Bittium Tough SDR Handheld™ and Bittium Tough SDR Vehicular™.

EHDRWH 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)

Waveform is under ratification as NATO STANAG 5651.


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 program was started in 2009 under the umbrella of the European Defense Agency (EDA), has been sponsored by the governments of Finland, France, Italy, Poland, Spain, and Sweden, and was awarded by the Organisation Conjointe de Coopération en matière d´ARmement (OCCAR) to the dedicated joint venture Alliance for ESSOR (a4ESSOR S.A.S.) to be in charge of managing the industrial consortium. The members of the industrial consortium are Bittium from Finland, Indra from Spain, Leonardo from Italy, Radmor from Poland, Rohde & Schwarz from Germany, and Thales from France.
