Sooner and higher—or damaged and worse? IEEE Spectrum‘s readers gravitated to the extremes within the sorts of telecom tales they learn this yr. On the one hand, tales about Russia’s satellite tv for pc jamming operations in Ukraine and stumbling 5G efficiency around the globe attracted loads of consideration from our guests in 2023. However readers additionally appeared significantly wanting to know extra about a few of the latest and the very best within the discipline—information fee data shattered and new methods to maintain identities and authentications secure, to call only a couple.
Hold scrolling to see the highest 10 tales that IEEE Spectrum readers spent probably the most time with over the course of 2023.
1. Satellite Jamming Reaches New Lows

Russia’s ongoing invasion of Ukraine has, over its practically two-year course, has revealed rather a lot about the current state of electronic warfare. In early 2023, it grew to become clear that one new department of digital warfare was the jamming of low Earth orbit (LEO) communications satellites. These satellites—usually CubeSats, and orbiting 2,000 kilometers or decrease—have introduced new challenges to satellite tv for pc jamming in comparison with their bus-sized geostationary brethren.
One of many key options for LEO satellite tv for pc constellations is their must incessantly hand off alerts to the following satellite tv for pc coming over the horizon. These hand-offs must occur roughly each 7 to 10 minutes, and every time, they introduce a brand new alternative for a jammer to interrupt the sign. LEO satellites additionally typically have much less house, compute, and energy for safety measures in comparison with bigger satellites—and plenty of depend on off-the-shelf parts that usually include further vulnerabilities.
The upside is that loads of work is being put into making these new satellite constellations more secure, despite the fact that it’s going to probably take loads of rethinking about the right way to design and construct the hundreds upon hundreds of satellites that make up these rising networks.
2. 5G Networks are Performing Worse. What’s Going On?

2023 might be the yr during which 5G actually hit its stride. The one drawback is—that stride is a bit much less spectacular than the telecom industry may have hoped for. Particularly, add and obtain speeds for 5G networks around the globe had been typically worse, in comparison with efficiency metrics from a yr earlier.
There are some caveats to this seeming flop—for one factor, each mobile technology tends to undergo some rising pains as new capability is first constructed out (and performs nicely) after which utilized by extra individuals (typically dragging speeds again down as a consequence of community congestion). However there are some distinctive facets of 5G that haven’t achieved it any favors: Piggybacking off of 4G networks, failure to capitalize on millimeter wave spectrum, and more and more complicated applied sciences going into the networks.
One factor to keep watch over for the years forward? How 5G’s sluggish begin impacts the analysis instructions that the industry prioritizes for 6G and beyond.
3. Vint Cerf on 3 Mistakes He Made in TCP/IP
Peter Adams
Vint Cerf (AKA “Mr. Internet“) was the recipient of the IEEE’s 2023 Medal of Honor. Cerf was instrumental within the early days of the Web, together with co-creating a lot of the infrastructure that the worldwide community depends on to at the present time. He didn’t get every part proper, nonetheless.
Cerf recounted to IEEE Spectrum three of the errors he made whereas creating the Internet Protocol Suite (extra generally known as TCP/IP). They could appear apparent in hindsight—simply what number of bits could be wanted for Web addresses (32 wouldn’t be sufficient!) or simply how essential safety could be. However Cerf did get rather a lot proper. Even when he admits that, like everybody else, he by no means actually appreciated what the Web would turn out to be within the following many years.
4. This Mirror Reverses How Light Travels in Time
Nature Physics
If you’re still hanging in there after time interfaces and reversed signals, it’s fair to now ask, why? Beyond just being a physical proof of something that has been theorized for six decades, there are practical applications in telecom (as well as radar and optical computing). Time reversal is commonplace in signal processing. Currently, that’s often done digitally, which places demands on a network’s time, energy, and memory capacity. A time interface that can naturally reverse signals could be a lot quicker and fewer complicated.
5. Google Develops Quantum-Safe Security Keys

The looming creation of quantum computing has had cybersecurity researchers hunting for ways to make cryptographic systems that may stand up to the brand new capabilities of such computer systems. Google researchers developed an answer for quantum-safe safety keys, the bodily exterior units that operate as a substitute for passwords. Their approach is a quantum-resilient implementation of the FIDO2 standard for safety keys.
Safety keys admittedly don’t have a broad uptake to this point—passwords stay way more frequent. However their use is rising, and they’re more durable to compromise as a result of they require really plugging within the bodily key to the pc to entry an utility or service. The Google researchers in query have helped to make sure that rising recognition gained’t be minimize quick when quantum computing turns into extra mainstream and conventional cryptography cracks. Sadly, even a post-quantum safety key stays simply as weak to side-channel assaults, which is when a hacker positive factors direct bodily entry to the important thing. So even sooner or later, attempt to not misplace a safety key.
6. Can We Identify a Person From Their Voice?
Chad Hagen
The technique has had a controversial past—the concept first emerged around 1911, but only came into prominence in the 1960s. By 1979, however, it was discredited, at least until the last few years. The technology’s effectiveness remains unproven, however. The U.S. Secret Service claims to be able to identify an individual from a voice-only line-up, and Chinese courts have taken voiceprints into account in hundreds of judgments already. But a lack of standards and an increasing reliance on deep learning models to make vocal matches—models that cannot explain the connections they’ve made—suggest there’s a long way to go before voiceprinting ever gets its day in court.
7. How Police Exploited the Capitol Riot’s Digital Records
Gabriel Zimmer
The U.S. Capitol riot on 6 January, 2021 resulted within the largest collective investigation in U.S. historical past, because the Federal Bureau of Investigations sought to trace down and establish as lots of the contributors as doable. However the FBI didn’t flip to state-of-the-art applied sciences and strategies to ID rioters—they used the identical surveillance strategies used daily, in even probably the most minor prison circumstances.
What actually set the FBI investigations aside from something that got here earlier than, as contributor Mark Harris wrote for IEEE Spectrum on the two-year anniversary of the incident, is the sheer scale of the surveillance instruments that the FBI tapped into, and the massive implications that has for the way forward for digital surveillance. Questions like whether or not or not applied sciences like geofencing are constitutional most likely gained’t be settled any time quickly—however they’ve implications for everybody, within the U.S. and past, as all of us create an increasing number of detailed digital data of our each day lives.
8. NASA’s Laser Link Boasts Record-Breaking 200-Gb/s Speed
MIT Lincoln Laboratory
Everybody loves a very good pace file. This yr, NASA broke the information fee file for laser communications by beaming 200 gigabits of knowledge per second from its TBIRD system (quick for TeraByte InfraRed Supply). TBIRD is onboard the company’s Pathfinder Technology Demonstrator 3 satellite tv for pc, orbiting roughly 530 kilometers above the Earth’s floor. The achievement doubled the laser comms file set simply final yr, additionally by TBIRD.
The speed is equal to TBIRD transmitting the equal of 1,000 high-definition films (2 terabytes of knowledge) in a single 5-minute overhead cross. It’s orders of magnitude quicker than the radio hyperlinks historically used for satellite tv for pc communications. Excessive-speed laser comms could be a boon for house exploration, though there are nonetheless some common hurdles to beat: Beams are likely to dissipate over interstellar distances, and the Earth’s ambiance can wreak havoc on sign high quality. (Though to that finish, NASA can boast one other latest laser comms file shattered, this one achieved mere weeks ago—the primary video streamed from deep house by laser, reaching 267 megabits per second obtain pace.)
Along with the above challenges that TBIRD confronted down, the crew additionally had to verify the parts—supposed for terrestrial use—would survive the pains of launch and the hostile house setting. In a single early vacuum take a look at earlier than launch, for instance, the system’s optical fibers melted as a result of warmth couldn’t be depraved away quick sufficient. Nonetheless, the researchers hope to have the ability to push laser communications as far out as the moon, and within the meantime, it’s going to have loads of applicability planetside as nicely.
9. Cory Doctorow: Interoperability Can Save the Open Web

For Doctorow, interoperability is the key to a good Internet future. Quite simply, things should simply work together. That would require reversing the trend by tech companies to turn their platforms, services, and apps into walled gardens. Instead, Doctorow wants to see a “virtuous circle,” in which users are free to switch between services without friction, forcing companies to actually do right by consumers. And he’s got some ideas for the right way to make that occur.
10. Fiber-Optic Cables Are Natural Earthquake Detectors

Fiber-optic cables: Nice for shifting a lot of information round rapidly. Because it seems, they’re additionally nice at detecting earthquakes. Due to the medium of transmission—gentle beams by way of a glass tube—they’re naturally delicate to any form of vibration, together with these from an earthquake.
Seismometers are costly to keep up—the state of California alone has over 700 of them, they usually every price as much as US $50,000. After all, putting in fiber optic cables isn’t low-cost, however they’ll pull double obligation as communications channels and earthquake detectors. They usually’re already (nearly) all over the place.
