Trust us, you need to pay attention to Samsung’s new mobile modem

Samsung has announced the Exynos Modem 5100, something that would usually be a relatively uninteresting piece of equipment, but made more special here because of its 5G capabilities. Be prepared — the onslaught of 5G-related technology is only just getting started.

What makes this special? It’s almost certainly the modem that will provide 5G connectivity for future 5G smartphones and other mobile devices from Samsung and its partners. Samsung does not explicitly state which devices it will be used in or when it will happen, but does say the modem has been successfully tested using a 5G “end user equipment prototype” — that’s a phone to you and me — equipped with the modem and connected to a 5G base station.

The good news is the Exynos Modem 5100 isn’t solely a 5G modem, as it will connect to most networks we use right now, including 2G, 3G, HSPA, 4G LTE. This is essential, as 5G will take a while to become widely available, and even with a 5G phone in our hand, we’ll have to fall back on 4G LTE and perhaps even 3G regularly for a start.

Samsung also estimates the kind of speed boost we’ll get from a phone that uses the Exynos 5100 Modem. The maximum downlink, says Samsung, will be between 2Gbps and 6Gbps, depending on the type of connection it has at the time. This means the connection could be up to five times faster than Samsung’s current modems. Squeezing all this technology, both current and future, into a single chip that unlike Motorola’s 5G Moto Mod, stays hidden away inside a device is a major step towards a consumer-friendly 5G’s launch.

5G’s actual launch window is still unknown, even with Verizon’s bluster surrounding the 5G Moto Mod, and even when it does come we’ve no idea how many people will be able to take advantage of such a fast connection, or how much it will cost. Samsung has warned that the Galaxy S10, expected early in 2019, will not be a 5G phone, indicating it will be later in the year before we see a compatible device from the manufacturer. When it does come, it will likely have the Exynos Modem 5100 inside.

One other thing to consider here is the use of the Exynos name. This may mean only Samsung’s phones that use its own Exynos processors — usually launched internationally — will get the Exynos Modem 5100, and Qualcomm-powered devices launched in the U.S. and selected other regions will use a different chip. The modem’s announcement comes soon after Samsung revealed a new RAM module suited to 5G mobile devices.

Samsung will make the Exynos Modem 5100 chip available to its customers, which may have different plans for it, before the end of this year.

Xiaomi 18 Fold has me questioning what a compact phone should look like, or even cost
I love compact phones, but these wide foldables have me rethinking the whole concept now
Xiaomi 18 Fold at IFA 2026

The best part of my job is the access to some of the coolest gadgets, especially the latest and greatest smartphones. Even then, I often found myself gravitating towards compact phones. At this point, I'd even skip a premium foldable just so I could have something a little more handy.

But every now and then, a larger phone would have this one feature or show me why a bigger phone is still so popular. I also want to play games, watch videos, and occasionally keep two apps open without fighting for every inch of screen space. A smaller phone makes many parts of my life easier, but the compromises aren't nonexistent. Simply making the phone wider may solve those problems, but eventually it becomes harder to handle again.

Xiaomi’s latest foldable has me convinced this design is here to stay
The Xiaomi 18 Fold pairs an unusual wider design with a surprisingly large battery, homegrown silicon, and flagship cameras, all packed into a 219-gram body.

September is becoming a very interesting month for foldable phones, and Xiaomi has just added another to the pile. The Xiaomi 18 Fold has launched in China with a shorter, wider shape that looks a little like a passport when closed. It’s quite a departure from the tall and narrow book-style foldables we’ve become used to, but Xiaomi isn't alone in thinking this might be the way forward.

Samsung already went down a similar road with the Galaxy Z Fold 8 in July, giving it a shorter, wider footprint and a 4:3 display when unfolded. Apple is expected to reveal its first foldable iPhone on September 9 — just two days after Xiaomi's launch — and rumors have repeatedly pointed toward a similar passport-style design. Then there's Huawei, which launched the Mate XT 2 today as well, although it is taking things in an entirely different direction with a tri-fold design.

Huawei’s latest tri-fold can take an ECG, and it’s like the old Galaxy era is back
This Samsung Galaxy S5 feature is getting revived for Huawei's $3000 tri-folding phone

Huawei just dropped its new tri-fold as a spectacular piece of hardware. The redesigned Mate XT 2 has a 10.2-inch folding display, a tougher inward-folding mechanism, and a jaw-dropping price tag. But now that Huawei has revealed the full specifications, one of its most interesting features has little to do with the screen.

The Mate XT 2 can record an electrocardiogram, or ECG, using electrodes built into its metal frame. So if a user unfolds the phone and holds the two sides with both hands, the device can capture a 30-second reading. The accompanying software then generates an ECG report that can flag sinus rhythm, atrial fibrillation, premature ventricular contractions, and premature atrial contractions in adults.
