As the philanthropic partner of IEEE, the IEEE Foundation expands the organization’s charitable body of work by inspiring philanthropic engagement that ignites a donor’s innermost interests and values.

One way the Foundation does so is by partnering with IEEE units to create memorial funds, which pay tribute to members, family, friends, teachers, professors, students, and others. This type of giving honors someone special while also supporting future generations of engineers and celebrating innovation.

Below are three recently created memorial funds that not only have made an impact on their beneficiaries and perpetuated the legacy of the namesake but also have a deep meaning for those who launched them.

EPICS in IEEE Fischer Mertel Community of Projects

The EPICS in IEEE Fischer Mertel Community of Projects was established to support projects “designed to inspire multidisciplinary teams of engineering students to collaborate and engineer solutions to address local community needs.”

The fund was created by the children of Joe Fischer and Herb Mertel to honor their fathers’ passion for mentoring students. Longtime IEEE members, Fischer and Mertel were active with the IEEE Electromagnetic Compatibility Society. Fischer was the society’s 1972 president and served on its board of directors for six years. Mertel served on the society’s board from 1979 to 1983 and again from 1989 to 1993.

“The EPICS in IEEE Fischer Mertel Community of Projects was established to inspire and support outstanding engineering ideas and efforts that help communities worldwide,” says Tina Mertel, Herb’s daughter. “Joe Fischer and my father had a lifelong friendship and excelled as engineering leaders and founders of their respective companies [Fischer Custom Communications and EMACO]. I think that my father would have been proud to know that their friendship and work are being honored in this way.”

The nine projects supported thus far have the potential to impact more than 104,000 people because of the work and collaboration of 190 students worldwide. The projects funded are intended to represent at least two of the EPICS in IEEE’s focus categories: education and outreach; human services; environmental; and access and abilities.

Here are a few of the projects:

• The Engineering Outreach at San Diego K–12 Schools project aims to bridge the city’s STEM education gap by sending IEEE members to schools to teach project-based lessons in mechanical, aerospace, electrical and computer engineering, as well as computer science. The project is led by the IEEE–Eta Kappa Nu honor society’s Kappa Psi chapter at the University of California San Diego and the San Diego Unified School District.
• Students from the Sahrdaya College of Engineering and Technology student branch in Kodakara, India, are developing an exoskeleton for nurses to support their lumbar spine region.
• Volunteers from the IEEE Uganda Section and local engineering students are designing and fabricating a stationary bicycle to act as a generator, providing power to families living in underserved communities. The goal of the project is to reduce air pollution caused by generators and supply reliable, affordable power to people in need.
• The IEEE Colombian Caribbean Section’s Increasing Inclusion of Visually Impaired People with a Mobile Application for English Learning project aims to ensure visually impaired students can learn to read, write, and speak English alongside their peers. The section’s members are developing a mobile app to help accomplish their goal.

IEEE AESS Michael C. Wicks Radar Student Travel Grant

The IEEE Michael C. Wicks Radar Student Travel Grant was established by IEEE Fellow Michael Wicks prior to his death in 2022. The grant provides travel support for graduate students who are the primary authors on a paper being presented at the annual IEEE Radar Conference. Wicks was an electronics engineer and a radio industry leader who was known for developing knowledge-based space-time adaptive processing. He believed in investing in the next generation and he wanted to provide an opportunity for that to happen.Ten graduate students have been awarded the Wicks grant to date. This year two students from Region 8 (Africa, Europe, Middle East) and two students from Region 10 (Asia and Pacific) were able to travel to Denver to attend the IEEE Radar Conference and present their research. The papers they presented are “Target Shape Reconstruction From Multi-Perspective Shadows in Drone-Borne SAR Systems” and “Design of Convolutional Neural Networks for Classification of Ships from ISAR Images.”

IEEE Nick Holonyak Jr. Medal for Semiconductor Optoelectronic Technologies

The IEEE Nick Holonyak Jr. Medal for Semiconductor Optoelectronic Technologies was created with a memorial fund supported by some of Holonyak’s former graduate students to honor his work as a professor and mentor. Presented on behalf of the IEEE Board of Directors, the medal recognizes outstanding contributions to semiconductor optoelectronic devices and systems including high-energy-efficiency semiconductor devices and electronics.

Holonyak was a prolific inventor and longtime professor of electrical engineering and physics. In 1962, while working as a scientist at General Electric’s Advanced Semiconductor Laboratory in Syracuse, N.Y., he invented the first practical visible-spectrum LED and laser diode. His innovations are the basis of the devices now used in high-efficiency light bulbs and laser diodes. He left GE in 1963 to join the University of Illinois Urbana-Champaign as a professor of electrical engineering and physics at the invitation of John Bardeen, his Ph.D. advisor and a two-time Nobel Prize winner in physics. Holonyak retired from UIUC in 2013 but continued research collaborations at the university with young faculty members.

“In addition to his remarkable technical contributions, he was an excellent teacher and mentor to graduate students and young electrical engineers,” says Russell Dupuis, one of his doctoral students. “The impact of his innovations has improved the lives of most people on the earth, and this impact will only increase with time. It was my great honor to be one of his students and to help create this important IEEE medal to ensure that his work will be remembered in the future.”

The award was presented for the first time at this year’s IEEE Honors Ceremony, in Boston, to IEEE Fellow Constance Chang-Hasnain and Life Fellow Fumio Koyama for “pioneering contributions to vertical cavity surface-emitting laser (VCSEL) and VCSEL-based photonics for optical communications and sensing.”

Establishing a memorial fund through the IEEE Foundation is a gratifying way to recognize someone who has touched your life while also advancing technology for humanity. If you are interested in learning more about memorial and tribute funds, reach out to the IEEE Foundation team: donate@ieee.org.

In 6G telecom research today, a crucial portion of wireless spectrum has been neglected: the Frequency Range 3, or FR3, band. The shortcoming is partly due to a lack of viable software and hardware platforms for studying this region of spectrum, ranging from approximately 6 to 24 gigahertz. But a new, open-source wireless research kit is changing that equation. And research conducted using that kit, presented last week at a leading industry conference, offers proof of viability of this spectrum band for future 6G networks.

In fact, it’s also arguably signaling a moment of telecom industry re-evaluation. The high-bandwidth 6G future, according to these folks, may not be entirely centered around difficult millimeter wave-based technologies. Instead, 6G may leave plenty of room for higher-bandwidth microwave spectrum tech that is ultimately more familiar and accessible.

The FR3 band is a region of microwave spectrum just shy of millimeter-wave frequencies (30 to 300 GHz). FR3 is also already very popular today for satellite Internet and military communications. For future 5G and 6G networks to share the FR3 band with incumbent players would require telecom networks nimble enough to perform regular, rapid-response spectrum-hopping.

Yet spectrum-hopping might still be an easier problem to solve than those posed by the inherent physical shortcomings of some portions of millimeter-wave spectrum—shortcomings that include limited range, poor penetration, line-of-sight operations, higher power requirements, and susceptibility to weather.

Pi-Radio’s New Face

Earlier this year, the Brooklyn, N.Y.-based startup Pi-Radio—a spinoff from New York University’s Tandon School of Engineering—released a wireless spectrum hardware and software kit for telecom research and development. Pi-Radio’s FR-3 is a software-defined radio system developed for the FR3 band specifically, says company co-founder Sundeep Rangan.

“Software-defined radio is basically a programmable platform to experiment and build any type of wireless technology,” says Rangan, who is also the associate director of NYU Wireless. “In the early stages when developing systems, all researchers need these.”

For instance, the Pi-Radio team presented one new research finding that infers direction to an FR3 antenna from measurements taken by a mobile Pi-Radio receiver—presented at the IEEE Signal Processing Society‘s Asilomar Conference on Signals, Systems and Computers in Pacific Grove, Calif. on 30 October.

According to Pi-Radio co-founder Marco Mezzavilla, who’s also an associate professor at the Polytechnic University of Milan, the early-stage FR3 research that the team presented at Asilomar will enable researchers “to capture [signal] propagation in these frequencies and will allow us to characterize it, understand it, and model it... And this is the first stepping stone towards designing future wireless systems at these frequencies.”

There’s a good reason researchers have recently rediscovered FR3, says Paolo Testolina, postdoctoral research fellow at Northeastern University’s Institute for the Wireless Internet of Things unaffiliated with the current research effort. “The current scarcity of spectrum for communications is driving operators and researchers to look in this band, where they believe it is possible to coexist with the current incumbents,” he says. “Spectrum sharing will be key in this band.”

Rangan notes that the work on which Pi-Radio was built has been published earlier this year both on the more foundational aspects of building networks in the FR3 band as well as the specific implementation of Pi-Radio’s unique, frequency-hopping research platform for future wireless networks. (Both papers were published in IEEE journals.)

“If you have frequency hopping, that means you can get systems that are resilient to blockage,” Rangan says. “But even, potentially, if it was attacked or compromised in any other way, this could actually open up a new type of dimension that we typically haven’t had in the cellular infrastructure.” The frequency-hopping that FR3 requires for wireless communications, in other words, could introduce a layer of hack-proofing that might potentially strengthen the overall network.

Complement, Not Replacement

The Pi-Radio team stresses, however, that FR3 would not supplant or supersede other new segments of wireless spectrum. There are, for instance, millimeter wave 5G deployments already underway today that will no doubt expand in scope and performance into the 6G future. That said, the ways that FR3 expand future 5G and 6G spectrum usage is an entirely unwritten chapter: Whether FR3 as a wireless spectrum band fizzles, or takes off, or finds a comfortable place somewhere in between depends in part on how it’s researched and developed now, the Pi-Radio team says.

“We’re at this tipping point where researchers and academics actually are empowered by the combination of this cutting-edge hardware with open-source software,” Mezzavilla says. “And that will enable the testing of new features for communications in these new frequency bands.” (Mezzavilla credits the National Telecommunications and Information Administration for recognizing the potential of FR3, and for funding the group’s research.)

By contrast, millimeter-wave 5G and 6G research has to date been bolstered, the team says, by the presence of a wide range of millimeter-wave software-defined radio (SDR) systems and other research platforms.

“Companies like Qualcomm, Samsung, Nokia, they actually had excellent millimeter wave development platforms,” Rangan says. “But they were in-house. And the effort it took to build one—an SDR at a university lab—was sort of insurmountable.”

So releasing an inexpensive open-source SDR in the FR3 band, Mezzavilla says, could jump start a whole new wave of 6G research.

“This is just the starting point,” Mezzavilla says. “From now on we’re going to build new features—new reference signals, new radio resource control signals, near-field operations... We’re ready to ship these yellow boxes to other academics around the world to test new features and test them quickly, before 6G is even remotely near us.”

This story was updated on 7 November 2024 to include detail about funding from the National Telecommunications and Information Administration.

Waiting for each part of a 3D-printed project to finish, taking it out of the printer, and then installing it on location can be tedious for multi-part projects. What if there was a way for your printer to print its creation exactly where you needed it? That’s the promise of MobiPrint, a new 3D printing robot that can move around a room, printing designs directly onto the floor.

MobiPrint, designed by Daniel Campos Zamora at the University of Washington, consists of a modified off-the-shelf 3D printer atop a home vacuum robot. First it autonomously maps its space—be it a room, a hallway, or an entire floor of a house. Users can then choose from a prebuilt library or upload their own design to be printed anywhere in the mapped area. The robot then traverses the room and prints the design.

It’s “a new system that combines robotics and 3D printing that could actually go and print in the real world,” Campos Zamora says. He presented MobiPrint on 15 October at the ACM Symposium on User Interface Software and Technology.

Campos Zamora and his team started with a Roborock S5 vacuum robot and installed firmware that allowed it to communicate with the open source program Valetudo. Valetudo disconnects personal robots from their manufacturer’s cloud, connecting them to a local server instead. Data collected by the robot, such as environmental mapping, movement tracking, and path planning, can all be observed locally, enabling users to see the robot’s LIDAR-created map.

Campos Zamora built a layer of software that connects the robot’s perception of its environment to the 3D printer’s print commands. The printer, a modified Prusa Mini+, can print on carpet, hardwood, and vinyl, with maximum printing dimensions of 180 by 180 by 65 millimeters. The robot has printed pet food bowls, signage, and accessibility markers as sample objects.

Currently, MobiPrint can only “park and print.” The robot base cannot move during printing to make large objects, like a mobility ramp. Printing designs larger than the robot is one of Campos Zamora’s goals in the future. To learn more about the team’s vision for MobiPrint, Campos Zamora answered a few questions from IEEE Spectrum.

What was the inspiration for creating your mobile 3D printer?

Daniel Campos Zamora: My lab is focused on building systems with an eye towards accessibility. One of the things that really inspired this project was looking at the tactile surface indicators that help blind and low vision users find their way around a space. And so we were like, what if we made something that could automatically go and deploy these things? Especially in indoor environments, which are generally a little trickier and change more frequently over time.

We had to step back and build this entirely different thing, using the environment as a design element. We asked: how do you integrate the real world environment into the design process, and then what kind of things can you print out in the world? That’s how this printer was born.

What were some surprising moments in your design process?

Campos Zamora: When I was testing the robot on different surfaces, I was not expecting the 3D printed designs to stick extremely well to the carpet. It stuck way too well. Like, you know, just completely bonded down there.

I think there’s also just a lot of joy in seeing this printer move. When I was doing a demonstration of it at this conference last week, it almost seemed like the robot had a personality. A vacuum robot can seem to have a personality, but this printer can actually make objects in my environment, so I feel a different relationship to the machine.

Where do you hope to take MobiPrint in the future?

Campos Zamora: There’s several directions I think we could go. Instead of controlling the robot remotely, we could have it follow someone around and print accessibility markers along a path they walk. Or we could integrate an AI system that recommends objects be printed in different locations. I also want to explore having the robot remove and recycle the objects it prints.

The Europa Clipper, set for launch in October, will explore a distant ocean world.

A collaboration between a space company and a fashion company yields something elegant.
