A team of Rice University engineers has secured a $1.9 million grant from the U.S. Department of Commerce’s National Telecommunications and Information Administration to develop a new way to test 5G networks.

The project will focus on testing 5G networks for software-centric architectures, according to a statement from Rice. The funds come from the NTIA's most recent round of grants, totaling about $80 million, as part of the $1.5 billion Public Wireless Supply Chain Innovation Fund. Other awards went to Virginia Tech, Northeastern University, DISH Wireless, and more.

The project at Rice will be led by Rahman Doost-Mohammady, an assistant research professor of electrical and computer engineering; and Ashutosh Sabharwal, the Ernest Dell Butcher Professor of Engineering and chair of the Department of Electrical and Computer Engineering. Santiago Segarra, assistant professor of electrical and computer engineering and an expert in machine learning for wireless network design, is also a co-principal investigator on this project.

"Current testing methodologies for wireless products have predominantly focused on the communication dimension, evaluating aspects such as load testing and channel emulation,” said Doost-Mohammady said in a statement. “But with the escalating trend toward software-based wireless products, it’s imperative that we take a more holistic approach to testing."

The new framework will be used to "assess the stability, interoperability, energy efficiency and communication performance of software-based machine learning-enabled 5G radio access networks (RANs)," according to Rice, known as ETHOS.

Once created, the team of researchers will use the framework for extensive testing using novel machine learning algorithms for 5G RAN with California-based NVIDIA's Aerial Research Cloud (ARC) platform. The team also plans to partner with other industry contacts in the future, according to Rice.

“The broader impacts of this project are far-reaching, with the potential to revolutionize software-based and machine learning-enabled wireless product testing by making it more comprehensive and responsive to the complexities of real-world network environments,” Sabharwal said in the statement. “By providing the industry with advanced tools to evaluate and ensure the stability, energy efficiency and throughput of their products, our research is poised to contribute to the successful deployment of 5G and beyond wireless networks.”

Late last year, the Houston location of Greentown Labs also landed funds from the Department of Commerce. The climatetech startup incubator was named to of the Economic Development Administration's 10th cohort of its Build to Scale program and will receive $400,000 with a $400,000 local match confirmed.

Houston-based nonprofit accelerator, BioWell, also received funding from the Build to Scale program.

Why this company adopted robotic dog technology

guest column

What has 4 legs, can recognize your face, and precisely obey commands on cue? If you guessed a dog, you’re half right.

I’m referring to robotic dogs, a modern marvel of innovative engineering. AT&T recently expanded our solution offers to include network-connected robotic dogs for public safety, defense, federal and state agencies, local police and fire departments, and commercial customers. We do this in collaboration with a leading provider of robotic dogs, Ghost Robotics.

Robotic dogs are just one way we are proving the innovation and transformational possibilities of 5G and IoT. Network-connected robotic dogs can deliver a broad range of IoT use cases, including many that have previously required putting personnel in dangerous situations. Here’s a quick look at some of the fantastic capabilities network-connected robotic dogs deliver.

  • Our robotic dogs can support public safety agencies and organizations on FirstNet – the nation’s only network built with and for America’s first responders. FirstNet delivers always-on prioritized network connectivity for these “first responder” robotic dogs, helping them stay connected during disaster response and recovery, facilities surveillance, and security operations. They can support search and rescue, venture into areas that could imperil human lives, and support the ability to reestablish local communications services following major infrastructure damage.
  • We can integrate Geocast into the robotic dogs to provide Beyond-Visual-Line-of-Sight (BVLOS) operational command and control so that operators of the dogs can be located virtually anywhere in the world and remotely operate them. Geocast is an AT&T innovation covered by 37 patents.
  • The robotic dogs can be equipped with sensors that allow them to operate autonomously without human intervention. They can be outfitted with drones that can launch and return to their backs while in motion, allowing the drones and dogs to perform missions as an integrated team.
  • Rugged terrain? Water? Not a problem. These robotic dogs can move across natural terrain, including sand, rocks, hills, rubble, and human-built environments, like stairs. They can operate fully submerged in water and, like living dogs, can swim.
  • An early use case adopted by the military involves equipping our robotic dogs with wireless network-connected cameras and deploying them to patrol military bases. Robotic dogs we provided to the Air Force at Tyndall Air Force Base in the Florida panhandle are doing just that. Our robotic dogs patrol the flight line and base perimeter at Tyndall, feeding video data in real-time to base personnel who can safely track activity 24/7/365 and support the safety of base operations. They can perform the same task for commercial users, indoors or outdoors. For example, they can patrol the perimeters of large warehouses or outdoor fence lines.
  • They can also support hazmat efforts, inspect mines and high-voltage equipment, and detect explosive devices including improvised explosive devices (IEDs): all while keeping people out of harm’s way.
  • Another interesting use case involves equipping robotic dogs with Long Range Acoustic Devices (LRADs). LRADs are sound cannons that produce noise at high decibels and varying frequencies. We have discussed with the Navy the possibility of outfitting our robotic dogs with sound cannons to warn off wild boars and feral dog packs that have impeded operating crews working on telecommunications infrastructure located in remote areas of one of its bases.

Commercial applications for network-connected robotic dogs are proliferating. Utility companies, for example, are using robotic dogs equipped with video cameras to perform routine equipment inspections in substations. Human inspection requires operators to shut down the facilities during inspections; the robotic dogs eliminate the need to take this precaution. Allied Market Research projects a $13.4 billion global market for the particular use case of robotic dogs performing such inspections.

Our robotic dogs can also be equipped with technology that extends network connectivity into difficult-to-reach areas or mechanical arms that can grip and carry materials such as tools. Their use cases include Pick and Pack capabilities for warehouse operations to improve order fulfillment efficiency.

And this is just the beginning. We’ve said from the outset that the 5G journey of innovation and solution development would evolve to deliver new ways to conquer many challenges.

Now, we’ve let the dogs out.

How 5G and smart cities technology are transforming the city of Houston

guest column

A firefighter stands in front of a burning building in Sunnyside. A drone buzzes overhead to capture video of the parts of the structure they can't get eyes on. Infrared technology helps them see "through" the building to where people may be trapped. Robotic cameras are sent in to provide live video from inside, while a tablet shows blinking dots in real time of where the other firefighters are as they move through the different floors of the building.

An injured civilian is pulled out of the flames. A drone delivers potentially life-saving medication while the paramedics assess the damage. The victim's medical records are shared instantaneously with the hospital, and paramedics are connected live to the emergency room while in-transit. As they make their way to the hospital, traffic signals are a step ahead – lights are green at just the right time on Reed and Almeda, clearing the way for an expedited ride and keeping traffic safe for all until the ambulance arrives at the hospital where medical personnel already know what's needed and are ready to jump into action.

It may sound like something out of a science fiction novel, but much of this is already happening. And the parts that aren't commonplace yet may be a reality very soon. We've heard about smart cities technology for some time, and different cities will adopt technology at different paces, but the pieces are finally coming into place.

What has changed to bring this futuristic world into the present? 5G.

There's a lot of noise out there about 5G, and from a consumer standpoint most of the chatter is about speed. Yes, 5G is faster, but here at AT&T we're quick to point out that speed is only the beginning: The capacity and responsiveness of 5G technology is what makes it revolutionary for use cases like these.

According to analyst research reported by CIO Magazine, 4G technology allows around 2,000 devices all connecting at the same time in a 1-kilometer area (0.386 miles). It's the reason that you might have trouble getting a call or a text to go through when you're at a crowded stadium. The network is ready and willing, but too much demand on one location slows things down.

Think about all the connections necessary in the above scenario. The drones, each firefighter, the robotic camera, the tablets, the ambulance and its equipment, sensors in the building, the hospital and all the people waiting there, the traffic signals… the list goes on. Well, 5G technology enables something called Massive IoT and can mean as many as 1 million devices can be connected in that same kilometer range, according to analyst research reported by CIO Magazine. That's game changing. AT&T has already installed its fastest 5G+ technology at the Toyota Center. Hopefully the next time you're there you'll feel the difference for yourself.

But having all those things talk to each other only makes a real difference if the connection is uninterrupted and in as real time as possible. 5G gives us that, as well. Ultra-low latency reduces response times to milliseconds. And when you add near-zero lag time to all those connections, the future becomes the present.

At AT&T we're passionate about public safety. That's why we created FirstNet, the first dedicated network exclusively for first responders, which ensures that the lines of communication stay open when they're needed the most. Harris Health System and Harris County Juvenile Probation are among the agencies already using the network. Going forward, FirstNet could be a crucial part of smart cities technology as capabilities increase.

There are plenty of use cases that 5G will continue to enhance: Think live feeds of police body cameras and locations when in a pursuit, helping increase efficiency and accountability. Think about the first responders themselves. Did you know that heart attack is the leading cause of death among firefighters? Vital signs could be monitored allowing alerts to a fire company of an elevated heart rate in their crew, potentially saving the life of a lifesaver.

5G could be the catalyst that leads to the true adoption of autonomous cars, as millions of sensors allow not only vehicle to vehicle communication, but could also integrate pedestrian traffic, making it safer for everyone as we move towards assisted and eventually self-driving vehicles.

Utility grid sensors could allow power companies to plan more effectively for use, pinpoint outages quickly, and use AI to divert energy and heal itself.

And we all know about Houston traffic. What if there's a world coming soon where we could alleviate just 20 percent of the congestion through smart city technology? In an hour commute, you just got 12 minutes back to spend with your family.

The technology is already getting smarter. The cities won't be far behind.

Houston is poised to lead 5G growth in Texas, according to a new report

leading the stream

Based on one key measure, Houston sits at the forefront of a telecom revolution that could spark a regional economic impact of more than $30 billion.

Data published recently by the Texas Comptroller's Office points out that as of last November and December, Houston led all cities in Texas for the number of so-called "small cells." Small cells are a key component in the rollout of ultra-high-speed 5G wireless communication throughout the Houston area and the country.

As the Texas Comptroller's Office explains, small cells are low-powered antennas that communicate wirelessly via radio waves. They're usually installed on existing public infrastructure like street signs or utility poles, instead of the big communication towers that transmit 4G signals.

The comptroller's tally shows Houston had approved 5,455 small-cell sites as of the November-December timeframe. That dwarfs the total number of sites (1,948) for the state's second-ranked city, Dallas.

"Houston is in the vanguard of small cell permitting in Texas, and not just because it's the state's largest city; advocates have lauded its proactive approach to 5G. Other cities, particularly smaller ones, are lagging well behind," the Comptroller's Office notes.

According to CTIA, a trade group for the wireless communications industry, 5G holds the promise to deliver an economic impact of $30.3 billion in the Houston area and create 93,700 jobs. The group says industries such as health care, energy, transportation, e-commerce, and logistics stand to benefit from the emergence of 5G.

"Maintaining world-class communications infrastructure is a requirement for success in a rapidly changing global economy. Small cells and fiber technology are the key foundational components for network densification and robust 5G. Cities like Houston that have embraced the need for this infrastructure will see the benefits of 5G faster than others," Mandy Derr, government affairs director at Houston-based communications infrastructure REIT Crown Castle International Corp. and a member of the Texas 5G Alliance, tells InnovationMap.

Derr says leaders in Houston have embraced the importance of small-cell technology through "reasonable and effective" regulations and processes aimed at boosting 5G capabilities. Three major providers of wireless service — AT&T, T-Mobile, and Verizon — offer 5G to customers in the Houston area.

"More small cells and fiber provide greater and faster access for the masses, enabling the connectivity that is essential to our businesses today — whether it's accepting payments on a mobile card reader, completing a sale on the go, or reliably reaching consumers where they are," Derr says.

In a blog post, Netrality Data Centers, which operates a data center in Houston, proclaims that Houston is shaping up to be a hub of 5G innovation.

"Houston has always been on the frontline," Mayor Sylvester Turner said during a 5G roundtable discussion in 2019. "It is who we are. It is in our DNA. We are a leading city. We didn't wait for somebody else to go to the moon. Or to be the energy capital of the world. Or the largest medical center in the world. But you don't stay at the front if you don't continue to lead."

Houston medtech startup clears FDA approval for new surgical tool

precision surgery

Houston-based Prana Surgical will soon bring a new electrosurgical tool to operating rooms around the country. The Prana System officially cleared U.S. Food and Drug Administration (FDA) approval earlier this month.

"Receiving FDA clearance for the Prana System represents a defining milestone for our company," Joanna Nathan, CEO and co-founder of Prana Surgical, said in a news release. "Surgeons today are increasingly focused on achieving precise outcomes while minimizing disruption to healthy tissue. The Prana System was designed to support that shift by integrating targeting and excision into a single, streamlined tool."

Prana Surgical began as Prana Thoracic in 2022. Back then, the company primarily focused on developing screening tools for lung cancer diagnosis. It raised $6 million in series A funding rounds in 2023 and 2024 before transitioning to broader surgical needs in 2025.

The Prana System is a minimally invasive, image-guided, single-use tissue extraction tool designed to retrieve samples without damaging healthy tissue. The tool is still designed with the respiratory system in mind, helping Prana in the fight against lung cancer and other thoracic diseases.

Reducing the impact of tissue extraction via electrosurgery and enhanced image scanning can significantly reduce complications. The Prana System combines localization and tissue-cutting capabilities in one, which keeps surgeons from having to swap out components during a procedure, making for a smoother process. It can core, cut and feel blood vessels on the way toward the intended target, giving surgeons greater control over tissue preservation.

"Electrosurgery is foundational to modern surgery, but there is still opportunity to improve how energy-based tools are applied in minimally invasive settings," Nathan added. "Our goal is to introduce a new class of image-guided surgical tools that enable more precise intervention across a range of procedures."

The company projects sales of $7.5 billion from the Prana System in the United States, estimating that 2.5 million surgical modules will be able to use the new tool. While starting out focused on biopsies, the company plans to evolve the system into other procedures, such as ablation, in the future. It is also planning for a controlled U.S. clinical rollout as it moves toward commercialization

Texas still ranks as No. 1 in U.S. for inbound moves, but growth dips

by the numbers

Texas continues to be the country’s No. 1 magnet for newcomers from other states, giving a boost to the state’s economy. However, Texas’ appeal weakened in 2024 compared with the previous year, due in large part to spiking home prices.

An analysis of U.S. Census Bureau data by self-storage platform StorageCafe shows Texas saw net interstate migration of 76,000 people in 2024. Texas’ net interstate migration dropped nearly 50 percent from 2023, according to the analysis. Net migration refers to the number of incoming residents minus the number of outgoing residents.

California remained the top source of newcomers for Texas, sending nearly 77,000 residents to the Lone Star State in 2024, the analysis says. Florida ranked second, followed by New York, Colorado and Illinois.

“These trends reveal Texas’ continued pull from both high-cost coastal markets and other large Sun Belt states, resulting in a mix of affordability-driven and job-driven relocation,” StorageCafe says.

Putting a damper on the influx of new residents: a roughly 124 percent surge in Texas home prices over the past decade, according to StorageCafe.

“While the state remains significantly more affordable than California, its top feeder state, the once-wide pricing gap has narrowed,” says StorageCafe. “For many movers, Texas is still a relative bargain, but no longer an undisputed one.”

Nonetheless, Texas keeps attracting young, highly educated people, which bodes well for the state’s long-term economic outlook, StorageCafe says. More than half of new arrivals to Texas in 2024 held at least a bachelor’s degree, and the age of newcomers averaged 32.

Where are most of these young, highly educated newcomers settling?

Lloyd Potter, former Texas state demographer, tells StorageCafe that population growth in Texas is happening most rapidly in suburban “ring counties” at the expense of slowing growth in urban cores. Ring counties are on the outskirts of major metro areas.

“Many people are moving from urban cores to suburban rings seeking lower costs, newer housing, better schools, and more space,” Potter says. “Typically, a move to a suburban county will be within commuting or hybrid‑commuting distance of major metro economies.”

Artemis II makes historic call to space station with help from Houston Mission Control

History in the making

Still aglow from their triumphant lunar flyby, the Artemis II astronauts made more history Tuesday, April 7: calling their friends aboard the International Space Station hundreds of thousands of miles away as they headed home from the moon.

It was the first moonship-to-spaceship radio linkup ever. NASA's Apollo crews had no off-the-planet company back in the 1960s and 1970s, the last time humanity set sail for deep space.

"We have been waiting for this like you can’t imagine,” Artemis II commander Reid Wiseman called out.

For Christina Koch on Artemis II and Jessica Meir aboard the space station, it marked a joyous space reunion despite being 230,000 miles (370,000 kilometers) apart. The two teamed up for the world's first all-female spacewalk in 2019 outside the orbiting lab.

Koch told her “astro-sister” that she'd hoped to meet up with her again in space “but I never thought it would be like this — it's amazing.”

“I'm so happy that we are back in space together,” Meir replied, “even if we are a few miles apart.”

Houston's Mission Control arranged the cosmic chitchat between the four lunar travelers and the space station's three NASA and one French residents.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

“It just made it even more special. It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive,” she told the space station crew. “The specialness and preciousness of that really is emphasized” when viewing the home planet from the moon.

By late Tuesday afternoon, the Artemis II astronauts had beamed back more than 50 gigabytes' worth of pictures and other data from the previous day's lunar rendezvous, which set a new distance record for humanity. The highlight: an Earthset photo reminiscent of Apollo 8's Earthrise shot from 1968.

"While they are inspirational and, I think, allow all of us to really feel a little bit of what they were feeling, there's also a lot of science hidden inside of those images," said Mission Control's lead lunar scientist Kelsey Young. “The conversations and the science lessons learned are just beginning."

During a debriefing with Young, the astronauts recounted how they spotted a cascade of pinpricks of light on the lunar surface from impacting cosmic debris. The flashes lasted mere milliseconds and coincided by chance with Monday evening's total solar eclipse.

Young said it was too soon to know whether the crew witnessed an actual meteor shower or more random, run-of-the-mill micrometeoroid hits. Either way, there were “audible screams of delight” in the science operations center, she said.

Koch described being awe-struck by not just the beauty of Earth, “but how much blackness there was around it.”

“It just made it even more special. It truly emphasized how alike we are, how the same thing keeps every single person on planet Earth alive,” she told the space station crew. “The specialness and preciousness of that really is emphasized” when viewing the home planet from the moon.

The first lunar explorers since Apollo 17 in 1972, Wiseman and his crew are aiming for a splashdown off the San Diego coast on Friday to wrap up the nearly 10-day test flight. The recovery ship USS John P. Murtha left port Tuesday for the target zone.

It sets the stage for next year's Artemis III, a lunar lander docking demo in orbit around Earth. Artemis IV will follow in 2028 with two astronauts attempting to land near the lunar south pole.

As for the Orion capsule’s pesky potty, Mission Control assured the astronauts that no maintenance was required Tuesday. The toilet has been on-and-off limits to the crew ever since last week’s launch, prompting them to rely on a backup bag-and-funnel system for urinating.

NASA Administrator Jared Isaacman told the crew following the lunar flyby Monday night: “We definitely have to fix some of the plumbing” ahead of the next Artemis mission. Engineers suspect a clogged filter in the overboard flushing system.

Aside from the toilet and other relatively minor matters, the mission has gone well, Isaacman noted at a news conference Tuesday, “but I'll breathe easier when we get through reentry and everybody's under chutes and in the water.”
