Waveform for a Coalition<br />

Editor’s Note: This is another in a regular series of updates on the Joint Tactical Radio System (JTRS), as provided by the<br />

program’s Joint Program Executive Office (JPEO).<br />

The JPEO JTRS has announced the approval of the operational<br />

requirements document (ORD) underpinning the Coalition Wideband<br />

Networking Waveform (COALWNW) specification. The ORD represents<br />

the consolidated and prioritized operational requirements of the<br />

nations participating in the COALWNW international agreement and<br />

is intended to support potential future development of a common,<br />

interoperable waveform. This milestone is an important step toward<br />

achieving enhanced interoperability and communication between the<br />

United States and coalition partners.<br />

Enhanced interoperability among coalition partners is an essential<br />

requirement on the modern battlefield, with multinational coalitions<br />

becoming the norm for conducting military operations in hot spots<br />

around the world. The COALWNW tactical networking capability<br />

will allow coalition partners to exchange secure wideband voice,<br />

data and video between national software defined radios in the land,<br />

air and maritime domains. These capabilities will significantly<br />

contribute to improved coordination, shared situational awareness,<br />

reduced chance of fratricide, and secure provisioning of effects across<br />

multinational boundaries.<br />

In June 2009, nine nations (Australia, Finland, France, Germany,<br />

Italy, Spain, Sweden, United Kingdom and United States) agreed to<br />

jointly develop a wideband networking waveform to enable tactical<br />

interoperability among coalition forces. This waveform is known as<br />

the COALWNW (pronounced Coal-Win).<br />

The COALWNW capability will be designed, developed and tested<br />

using a three-phased approach: waveform specification, waveform<br />

development and interoperability testing. During the first phase,<br />

the participating nations have developed a single set of operational<br />

requirements that will underpin the COALWNW specification. To<br />

evaluate and baseline these requirements, the nations performed<br />

a comprehensive requirements definition process that included an<br />

analysis of current waveform developments.<br />

When waveform development begins in the second phase, COAL-<br />

WNW will be delivered incrementally with increased functionality<br />

incorporated in later increments. In this manner, developmental risk<br />

can be effectively managed and early deployment of initial capability<br />

can be achieved. The first increment will focus on delivering interoperability<br />

within the ground environment, inclusive of many maritime<br />

and air support assets.<br />

A working group comprising members from the nine COALWNW<br />

nations is studying alternatives to determine the best acquisition<br />

strategy for the initial increment. The member nations expect that<br />

other nations will join the COALWNW effort for development of the<br />

first increment.<br />

A key enabler to the COALWNW capability is the introduction of<br />

software defined radio programs within the partner nations. In a software<br />

defined radio, the software defines the communication characteristics<br />

of the radio and software waveforms may be reused and ported<br />

onto different radio hardware (similar to computer applications). Once<br />

developed, the intent is to port COALWNW onto various national software<br />

defined radio hardware hosts, thus ensuring coalition interoperability<br />

through a diverse range of platforms. O<br />
