Last year, Houstonians Clayton and Emily Harris became the first commercial 5G customers. Now, a full year later, the Houston has a major seat at the table that's discussing the advancement of 5G technology.

At a forum on Tuesday, October 1, hosted by CTIA and the Center for Houston's Future, experts discussed Houston's role in the conversation about 5G. Here are some overheards from the morning event.

“We cannot take our leadership in 4G for granted as we transition to 5G.”

— Senator Ted Cruz. Cruz's keynote address warns of the United States resting on its laurels in the race to 5G. While the country had the edge on foreign competition for 4G, that doesn't mean 5G will have the same result, he says. In fact, Cruz cites multiple studies that show China and South Korea lead the race in 5G. Deloitte's research found that China has outspent the U.S. by $24 billion and has built 350,000 new sites, while the U.S. has built fewer than 30,000. The study also showed China is prepared to invest $400 billion. This information aside, Cruz tells the crowd that America has the ability to win the race to 5G.

“I think it’s a wonderful story to see how Texas has been leading the way.” 

— Brendan Carr, FCC commissioner. Carr references the Harris family, as well as other Texas cities he's visited that have been working hard to advance 5G. For Carr, expanding and implementing 5G is a huge opportunity for job creation. "The U.S. isn't the only country in the world that wants these jobs," he says to the crowd. "They're not the only country that wants to see the half a trillion dollars in economic growth that's going to come from this next-generation technology."

“I’ll admit, I’m an optimist, but there are significant challenges to making this 5G future a reality.”

— Jesse Bounds, director of innovation for the city of Houston. Bounds cited a few obstacles to overcome. There's a need for massive investment in infrastructure to blanket cities in 5G, and telecom companies are expected to spend $8 billion over the next five years to build this infrastructure, and cities too will need to invest in smart city technology. Consumers will need to pay more for data, and US consumers pay some of the highest rates in the world already. Not to mention the fact that a third of Americans don't have access to home internet. "As we build the infrastructure of the future, we must do so in a way that closes the digital divide so that those Americans can enjoy the same level of opportunity and prosperity that we do," Bounds says.

"Houston’s 5G network performance is 17 times better than the 4G. That’s today, in the very early days of 5G.”

— Paul Challoner, vice president of network product solutions at Ericsson. Challoner tells the crowd that of course this affects speed of data transferring and that is a huge pro for the technology, but there are other important perks for 5G advancement. The tech also affects device density, meaning that, a very large city like Houston, might have issues in dense areas. 5G also improves connectivity in crucial situations, like in the case of a surgeon using a device during surgery. Lastly, Challoner mentioned 5G is the most advanced technology when it comes to cybersecurity.

"One area that I’m most excited about is all the things that we don't talk about. All the applications that haven't yet been imagined, that are being dreamt up by software developers in their dorm rooms."

— Mishka Dehghan, vice president of 5G development at Sprint. Dehghan points out that 10 years ago, no one could have imagined ride sharing, now that is a huge industry with developing technology thanks to mobile data usage. With with the onset of 5G, she says she can't wait to see what technology is created in the next 10 years.

How Houston innovators played a role in the historic Artemis II splashdown

safe landing

Research from Rice University played a critical role in the safe return of U.S. astronauts aboard NASA’s Artemis II mission this month.

Rice mechanical engineer Tayfun E. Tezduyar and longtime collaborator Kenji Takizawa developed a key computational parachute fluid-structure interaction (FSI) analysis system that proved vital in NASA’s Orion capsule’s descent into the Pacific Ocean. The FSI system, originally developed in 2013 alongside NASA Johnson Space Center, was critical in Orion’s three-parachute design, which slowed the capsule as it returned to Earth, according to Rice.

The model helped ensure that the parachute design was large enough to slow the capsule for a safe landing while also being stable enough to prevent the capsule from oscillating as it descended.

“You cannot separate the aerodynamics from the structural dynamics,” Tezduyar said in a news release. “They influence each other continuously and even more so for large spacecraft parachutes, so the analysis must capture that interaction in a robustly coupled way.”

The end result was a final parachute system, refined through NASA drop tests and Rice’s computational FSI analysis, that eliminated fluctuations and produced a stable descent profile.

Apart from the dynamic challenges in design, modeling Orion’s parachutes also required solving complex equations that considered airflow and fabric deformation and accounted for features like ringsail canopy construction and aerodynamic interactions among multiple parachutes in a cluster.

“Essentially, my entire group was dedicated to that work, because I considered it a national priority,” Tezduyar added in the release. “Kenji and I were personally involved in every computer simulation. Some of the best graduate students and research associates I met in my career worked on the project, creating unique, first-of-its-kind parachute computer simulations, one after the other.”

Current Intuitive Machines engineer Mario Romero also worked on Orion during his time at NASA. From 2018 to 2021, Romero was a member of the Orion Crew Capsule Recovery Team, which focused on creating likely scenarios that crewmembers could encounter in Orion.

The team trained in NASA’s 6.2-million-gallon pool, using wave machines to replicate a range of sea conditions. They also simulated worst-case scenarios by cutting the lights, blasting high-powered fans and tipping a mock capsule to mimic distress situations. In some drills, mock crew members were treated as “injured,” requiring the team to practice safe, controlled egress procedures.

“It’s hard to find the appropriate descriptors that can fully encapsulate the feeling of getting to witness all the work we, and everyone else, did being put into action,” Romero tells InnovationMap. “I loved seeing the reactions of everyone, but especially of the Houston communities—that brought me a real sense of gratitude and joy.”

Intuitive Machines was also selected to support the Artemis II mission using its Space Data Network and ground station infrastructure. The company monitored radio signals sent from the Orion spacecraft and used Doppler measurements to help determine the spacecraft's precise position and speed.

Tim Crain, Chief Technology Officer at Intuitive Machines, wrote about the experience last week.

"I specialized in orbital mechanics and deep space navigation in graduate school,” Crain shared. “But seeing the theory behind tracking spacecraft come to life as they thread through planetary gravity fields on ultra-precise trajectories still seems like magic."

UH breakthrough moves superconductivity closer to real-world use

Energy Breakthrough

University of Houston researchers have set a new benchmark in the field of superconductivity.

Researchers from the UH physics department and the Texas Center for Superconductivity (TcSUH) have broken the transition temperature record for superconductivity at ambient pressure. The accomplishment could lead to more efficient ways to generate, transmit and store energy, which researchers believe could improve power grids, medical technologies and energy systems by enabling electricity to flow without resistance, according to a release from UH.

To break the record, UH researchers achieved a transition temperature 151 Kelvin, which is the highest ever recorded at ambient pressure since the discovery of superconductivity in 1911.

The transition temperature represents the point just before a material becomes superconducting, where electricity can flow through it without resistance. Scientists have been working for decades to push transition temperature closer to room temperature, which would make superconducting technologies more practical and affordable.

Currently, most superconductors must be cooled to extremely low temperatures, making them more expensive and difficult to operate.

UH physicists Ching-Wu Chu and Liangzi Deng published the research in the Proceedings of the National Academy of Sciences earlier this month. It was funded by Intellectual Ventures and the state of Texas via TcSUH and other foundations. Chu, founding director and chief scientist at TcSUH, previously made the breakthrough discovery that the material YBCO reaches superconductivity at minus 93 K in 1987. This helped begin a global competition to develop high-temperature superconductors.

“Transmitting electricity in the grid loses about 8% of the electricity,” Chu, who’s also a professor of physics at UH and the paper’s senior author, said in a news release. “If we conserve that energy, that’s billions of dollars of savings and it also saves us lots of effort and reduces environmental impacts.”

Chu and his team used a technique known as pressure quenching, which has been adapted from techniques used to create diamonds. With pressure quenching, researchers first apply intense pressure to the material to enhance its superconducting properties and raise its transition temperature.

Next, researchers are targeting ambient-pressure, room-temperature superconductivity of around 300 K. In a companion PNAS paper, Chu and Deng point to pressure quenching as a promising approach to help bridge the gap between current results and that goal.

“Room-temperature superconductivity has been seen as a ‘holy grail’ by scientists for over a century,” Rohit Prasankumar, director of superconductivity research at Intellectual Ventures, said in the release. “The UH team’s result shows that this goal is closer than ever before. However, the distance between the new record set in this study and room temperature is still about 140 C. Closing this gap will require concerted, intentional efforts by the broader scientific community, including materials scientists, chemists, and engineers, as well as physicists.”
