SwRI installs private 5G network for research, development, testing and evaluation

Secure network cuts costs, expands off-site capabilities for 5G projects

2025-09-15

(Press-News.org) SAN ANTONIO — September 15, 2025 — Southwest Research Institute (SwRI) installed a private 5G research, development, test and evaluation network to boost security, eliminate dependency on outside mobile network providers and expand network access for advanced 5G projects. The secure, high-velocity 5G network allows rapid deployment of communication resources and wireless connectivity on the SwRI campus or off-site in the field, providing wide coverage for research and development.

The SwRI network supports a range of 5G advancements — including cybersecurity research, drone technology, edge computing initiatives, and antenna development and testing — but a private 5G network offers additional benefits and capabilities.

“A tactical mobile network is useful in various scenarios,” said Jody Little, a director in SwRI’s Defense and Intelligence Solutions Division who is leading the 5G network development. “The military needs solid communication when conducting operations. Severe weather and natural disaster victims need a reliable connection when services go out. Oilfield workers rely on 5G. A private, mobile network offers convenience, flexibility and a safety net in vulnerable areas.”

Fifth-generation mobile network technology, or 5G, processes large volumes of data swiftly and in real time. While the SwRI campus has a fixed network infrastructure, users can easily transport system base stations and equipment for remote installation.

“The network provides broadband communication without the need for fiber optic cables,” said Charles Almquist, an SwRI program manager who is part of the network development team. “It’s much quicker and easier to set up. It may take two days to run fiber, whereas we can set up our mobile 5G system, configure it and deploy it in a matter of hours. And it’s just as easy to tear down.”

SwRI’s private 5G network operates on the Citizens Broadband Radio Service, an unlicensed spectrum approved by the Federal Communications Commission for private network use. The network development team plans to expand the system beyond 5G to support next-generation 6G, which integrates satellite and artificial intelligence capabilities.

“Eventually, people will be working entirely on secure networks and not be as dependent on fiber. That’s coming,” Little said.

The private network was funded through SwRI’s Internal Research and Development program, which provides resources for future-focused, unproven concepts to advance technology for government and industry clients. The network achieved initial operating capability in August 2025.

A new perspective in bone metabolism: Targeting the lysosome–iron–mitochondria axis for osteoclast regulation

2025-09-15

Background: Osteoporosis is a common skeletal disorder characterized by excessive bone loss, leading to increased fragility and an increased risk of fractures. Osteoclasts, the bone-resorbing cells, are widely recognized as central players in this process. Osteoclast-mediated bone resorption relies critically on two organelles: lysosomes, which degrade the bone matrix, and mitochondria, which provide the necessary energy. Iron, acting as a key connector between lysosomes and mitochondria, has emerged as an essential regulator of osteoclast activity. ...

Few military spouses use formal support services during, after deployment

2025-09-15

CHAMPAIGN, Ill. — Cycles of deployment and reintegration can be stressful, disruptive times for military spouses and their families. Although the Department of Defense and its military communities offer a number of formal resources to help military spouses cope during these challenging periods, very few of those who participated in a recent study said they actually used them. Only 16.5% of those in the study had participated in a formal reintegration program after their partners returned from deployment. The findings are concerning and contribute to a growing body of research indicating that thousands of military spouses may not be receiving the support they need ...

Breakthrough in the hunt for light dark matter: QROCODILE project reveals world-leading constraints

2025-09-15

A new experiment called QROCODILE, led by the University of Zurich and the Hebrew University of Jerusalem, has achieved record sensitivity in the hunt for light dark matter. Using superconducting detectors cooled to near absolute zero, the team set world-leading limits on how dark matter interacts with ordinary matter — opening the door to future breakthroughs in one of physics’ greatest mysteries. [Hebrew University of Jerusalem]– Dark matter, the elusive substance that makes up about 85% of the universe’s mass, remains one of the greatest mysteries ...

2D x-ray imaging technique reveals hidden processes in CO2 electrolyzers

2025-09-15

Electrochemical devices that convert CO2 into useful chemicals are a promising route toward sustainable industrial production, yet their long-term stability remains a major challenge. A new study by researchers from Technical University of Denmark (DTU), Ecole Polytechnique Fédérale de Lausanne (EPFL), and the European Synchrotron Radiation Facility (ESRF) introduces a powerful in-operando two-dimensional X-ray diffraction imaging techniques that allows researchers to watch, in real time, what happens inside a membrane–electrode assembly (MEA)-based CO2 electrolyzer. The ...

Rational high entropy doping strategy via modular in-situ/post solvothermal doping integration for microwave absorption

2025-09-15

Materials scientists have long pursued advanced microwave absorption materials to address growing electromagnetic pollution challenges in both military stealth and civilian shielding applications. Transition metal dichalcogenides, particularly MoS2, have emerged as promising candidates due to their unique 2D layered structures and tunable electronic properties. However, conventional single-element doping strategies have shown limited effectiveness in achieving broadband absorption, while multi-element high-entropy doping in MoS2 systems remains ...

Recent advances in exciton-polariton in perovskite

2025-09-15

Perovskites, a class of materials known for their stellar performance in solar cells, are now making waves in the world of advanced optics. These versatile semiconductors can capture and emit light in ways that traditional materials like silicon cannot, offering a cheaper and simpler way to create cutting-edge technologies. This review explores a fascinating phenomenon called exciton-polaritons, hybrid particles formed when light and matter merge so strongly that they act as one. This merging, or “strong coupling,” happens when light bounces inside tiny cavities, interacting intensely ...

Over-the-counter sales of overdose reversal drug naloxone decline after initial surge

2025-09-15

Sales of the overdose reversal medication naloxone increased after it was made available to the public without a prescription but then dipped quickly in the period following debut of over-the-counter sales, according to a new RAND study. Over-the-counter sales of naloxone peaked during the first month of availability in September 2023, then declined rapidly before stabilizing until August 2024, when there was a small increase, according to the study published in the journal JAMA Internal Medicine. The drug can prevent death among people who have overdosed on ...

Global trends and disparities in social isolation

2025-09-15

About The Study: In this cross-sectional study, social isolation was found to have increased globally after the COVID-19 pandemic, with the initial increase disproportionately seen in lower-income populations and subsequent increases broadening across socioeconomic strata. Targeted interventions for vulnerable groups and research examining country-level policies are urgently needed to mitigate high isolation levels and reduce inequities.
