Wideband Networking Waveform

{{short description|Radio protocol used by US and NATO military}}

The Wideband Networking Waveform (WNW) is a military radio protocol for mobile ad hoc networking (MANETs) for software defined radios.{{cite web|last=Joint Tactical Networking Center|first=USA Department of Defense|title=OUR PRODUCTS|url=http://jtnc.mil/Pages/Products.aspx|publisher=USDOD|accessdate=7 January 2014}} It was developed as part of the Joint Tactical Radio System (JTRS) program of the U.S. Department of Defense, and was intended for US and NATO military use.

The ""WNW"" waveform uses an OFDM physical layer,{{cite web|publisher=Spectrum|url=http://www.spectrumsignal.com/products/pdf/wnw_ofdm_web.pdf|title=Wideband Networking Waveform OFDM PHY|accessdate=7 January 2014|archive-url=https://web.archive.org/web/20140312224424/http://www.spectrumsignal.com/products/pdf/wnw_ofdm_web.pdf|archive-date=12 March 2014|url-status=dead}} and with variable frequency usage to best utilize the available bandwidth.

The waveform uses the Software Communications Architecture (SCA) software architecture, and has NSA approved security.{{cite web|author=Defense Systems Staff|title=NSA certifies JTRS wideband networking waveform radio|url=https://defensesystems.com/articles/2012/05/24/agg-jtrs-ground-mobile-radio-nsa-certification.aspx|website=defensesystems.com|date=24 May 2012}}
