The AN/PRC-155 Manpack radio is the first tactical radio for the dismounted soldier to communicate using the Wideband Networking Waveform, delivering unprecedented capacity, speed and connectivity.

SCOTTSDALE, Ariz. – May 16, 2012 – General Dynamics C4 Systems recently demonstrated wireless high definition video and data transfer to government customers using the Wideband Networking Waveform (WNW) on the JTRS HMS AN/PRC-155 two-channel networking manpack radio. General Dynamics funded the implementation of the waveform using the same manpack hardware currently being produced under the JTRS HMS program of record. WNW delivers unprecedented capacity, speed and connectivity for voice, data and other large files moving through mobile tactical networks.

"The JTRS HMS program has provided the DoD with an operationally tested two-channel manpack that can readily incorporate new waveforms. This demonstration shows the potential of the HMS platform to support the services at higher tiers of the network," said Colonel John Zavarelli, Program Manager, Joint Tactical Radio System Handheld Manpack Small Form Fit (JTRS HMS).

One of three networking waveforms in the JTRS library, WNW provides the backbone function needed to seamlessly transport large amounts of data across the tactical network. The Soldier Radio Waveform (SRW) delivers networked voice and data communications for individual soldiers and edge devices that have tight size, weight and power requirements. The Mobile User Objective System (MUOS) waveform enables satellite communications and leverages advanced wireless technology that is similar to terrestrial cellular communications. A waveform provides the transport of information through a network including the physical signal, protocols and security as well as routing functions.

“WNW is running on the same radio hardware that we are shipping to the Army today so this is unlike any manpack offering on the market. The powerful waveform can also run on radios that fit into small vehicular installations as well as those used by dismounted soldiers,” said Chris Marzilli, president of General Dynamics C4 Systems. “The PRC-155 Manpack is the only tactical radio to demonstrate the successful use of all three networking waveforms: SRW, WNW and MUOS.”

General Dynamics C4 Systems is the prime contractor of the JTRS HMS radio program, which includes the two-channel PRC-155 networking manpack radio. These manpack radios are currently in low rate initial production and are in Multiservice Operational Test and Evaluation at Network Integration Exercise 12.2 in support of a full rate production decision scheduled for later this year. JTRS HMS program of record radios have competition built in so that the government can get the best, most cost-effective pricing for radios well into the future.
