VIAVI T/Rx Selected by U.S. Army Threat Systems Management Office for Critical Range Modernization Initiative

The Army plans to use T/Rx to fulfill a large portion of its requirement to replicate contested electromagnetic environments.

Rhea-AI Summary

VIAVI Solutions (NASDAQ: VIAV) announced that the U.S. Army's Threat Systems Management Office selected its T/Rx system for test-range modernization. The system will provide electromagnetic spectrum environments at Army ranges recently opened to private industry under the Test Range Private Industry Initiative. The initiative opens five facilities to commercial developers, including companies without existing government contracts, for testing drones, counter-drone systems, long-range fires and low-cost interceptors.

T/Rx also delivered on-demand electromagnetic complexity at a recurring test hosted by Camp Grayling in September 2026.

3 terms

software defined transceiver technical

"selected the VIAVI T/Rx software defined transceiver system"

A software defined transceiver is a radio device that performs both transmission and reception functions where key signal-processing tasks (modulation, demodulation, filtering, frequency selection, protocol handling) are implemented or controlled in software rather than fixed hardware. Hardware front ends still handle analog tasks like amplification, frequency conversion and analog-to-digital/digital-to-analog conversion, while the software runs the flexible, upgradable algorithms that determine how signals are encoded, decoded and routed. Because behavior is set by software, the same physical unit can support different frequencies, standards or features through firmware updates, but performance limits such as maximum bandwidth, sensitivity and regulatory compliance remain governed by the device’s hardware and certification.

electromagnetic spectrum (ems) technical

"to provide electromagnetic spectrum (EMS) environment at Army test ranges"

The electromagnetic spectrum (EMS) is the continuous range of all electromagnetic radiation, organized by wavelength or frequency from long-wavelength, low-frequency radio waves through microwaves, infrared, visible light, ultraviolet, X‑rays, to short-wavelength, high-frequency gamma rays. Electromagnetic radiation travels as oscillating electric and magnetic fields (often described as photons or waves); higher frequency corresponds to higher photon energy and different ways the radiation interacts with matter. The spectrum is continuous (band boundaries are conventional) and is typically divided into bands because different wavelengths behave differently and are regulated or used for different technologies and medical or scientific applications.

frequency-agile emitters technical

"generating representative waveforms, frequency-agile emitters"

Transmitters or radiating devices that can change their operating frequency quickly and deliberately while transmitting, using techniques such as frequency hopping, rapid tuning, or software-defined radio control. They alter frequency to avoid interference or jamming, share spectrum more efficiently, or adapt to regulatory and channel conditions; unlike fixed-frequency emitters, they require coordinated timing, control software or hardware, and must operate within assigned spectrum rules.

The T/Rx will deliver complex, realistic electromagnetic environments across newly opened Army test ranges to support drones, counter-drones and interceptor development

CHANDLER, Ariz., Oct. 13, 2026 /PRNewswire/ -- VIAVI Solutions Inc. (NASDAQ: VIAV) today announced that the U.S. Army's Threat Systems Management Office (TSMO), under Portfolio Acquisition Executive C2/CC2, has selected the VIAVI T/Rx software defined transceiver system to provide electromagnetic spectrum (EMS) environment at Army test ranges recently opened to private industry.

This selection supports the Test Range Private Industry Initiative, a landmark effort to open five premier range facilities to commercial developers of drones, counter-drone systems, long-range fires and low-cost interceptors to support rapid innovation at scale. The Army's initiative allows companies, including those without existing government contracts, to access the range infrastructure and accelerate the development of emerging warfighter technologies.

Realistic testing at these ranges depends on the ability to replicate the contested electromagnetic environments encountered on the modern battlefield. TSMO will utilize the VIAVI T/Rx system to fulfill a large portion of this requirement, leveraging the system's industry-leading EMS monitoring, recording, analysis and transmission capabilities.

"The Army's test range expansion initiative is the kind of acquisition reform that accelerates capability delivery to warfighters," said Doug Russell, Senior Vice President and General Manager, Aerospace & Defense, VIAVI Solutions. "VIAVI is proud to be selected by TSMO to provide the electromagnetic spectrum environment that makes these ranges operationally realistic. The T/Rx was designed to deliver the complexity and programmability that modern test events demand, and we look forward to supporting the development of the next generation of drones, counter-drones and interceptors."

Camp Grayling, one of the designated sites under the Test Range Private Industry Initiative, hosted a recurring electromagnetic unreliability test in September 2026. The VIAVI T/Rx system delivered on-demand EMS complexity, which is designed to reproduce contested electronic warfare conditions observed in Ukraine and enable developers to harden drone and counter-drone systems accordingly.

The T/Rx system is a compact, rugged, commercial software defined transceiver that combines simultaneous signal generation and collection in a single field-deployable unit. Operating across a broad range of instantaneous bandwidth, the T/Rx enables test range operators to create complex, diverse electromagnetic environments on demand, generating representative waveforms, frequency-agile emitters and multi-signal scenarios that replicate real-world contested EMS conditions.
