  • Apple Watch 11 Now Connects to Starlink for Messaging and Emergencies

    Apple Watch 11 Now Connects to Starlink for Messaging and Emergencies

    Key Takeaways

    1. Apple Watches can now connect to the Starlink network for messaging in remote areas, thanks to partnerships with Rogers and KDDI.

    2. The Apple Watch Ultra 3, Watch 11 Series, and Watch SE 3 can utilize Starlink messaging, with Rogers offering a free beta version for Apple Watch 11 users.

    3. KDDI in Japan provides a paid service for Starlink messaging, allowing users to send texts, share locations, and receive emergency alerts.

    4. Apple plans to enhance satellite messaging capabilities for iPhones, including image sharing and access for third-party apps, alongside Apple Maps for navigation in areas without cellular coverage.

    5. Future updates may allow direct satellite connectivity for iPhones and Android devices without needing a Starlink Mini dish, depending on the launch of Starlink’s V3 satellites in 2026.

    While Apple has put money into Globalstar as the satellite service for its iPhones, the new Watch series can now link up with the larger Starlink network from Elon Musk’s SpaceX.

    Starlink Support for Apple Watches

    Both Rogers in Canada and KDDI in Japan have revealed that the Apple Watch Ultra 3, the Watch 11 Series, and the Watch SE 3 can now utilize Starlink messaging even in remote areas. All Apple Watch models from 2025 that have cellular capabilities can benefit from the Starlink services provided by these companies. Rogers is offering its Starlink Cellular add-on in a beta version for free, allowing Apple Watch 11 users to send messages from their watches in places where there is no cellular coverage, thanks to Starlink satellites.

    Texting Options in Japan

    KDDI in Japan also supports Starlink messaging from the Apple Watch; however, this feature is a paid service, similar to what T-Mobile provides for many of its phones in the United States. KDDI notes, “In addition to sending and receiving text messages, Apple Watch can also share your location and receive emergency alert emails.”

    The likely implication of this is that T-Mobile may also introduce the Starlink satellite feature for the Apple Watch in the US, similar to its offerings for iPhones. Apple, which first introduced emergency satellite services for iPhones back in 2022, is now reportedly seeking to broaden its service options, which its Globalstar partner may struggle to provide without a significant upgrade to its constellation or a partnership with a bigger entity like SpaceX.

    Enhanced Messaging and Navigation

    Apple is aiming to enhance media messaging to include images and allow third-party app developers access to its satellite connectivity. Apple Maps is also set to join the satellite service, enabling iPhone users to navigate in areas lacking cellular coverage, just like Google Maps does with T-Satellite Starlink service.

    The iPhone 18 is expected to support the 5G NTN protocol for non-terrestrial connectivity, allowing its modem to maintain a connection by extending cell tower coverage with satellite signals when necessary. After SpaceX acquired Dish’s spectrum, Elon Musk has ambitious plans for Starlink to become a standalone carrier offering global 5G coverage via satellite, although at slower speeds than terrestrial networks, which are around 100 Mbps.

    Future of Connectivity

    With this setup, users won’t need the Starlink Mini dish while on the move and can connect directly to satellite broadband with their iPhones or Android devices. These plans depend on launching thousands of Starlink direct-to-cell V3 satellites, which SpaceX is set to start in 2026. Until then, limited Starlink connectivity is accessible for both the Apple Watch and iPhone through various carriers.

  • Smartwatches’ Accuracy in Detecting Atrial Fibrillation: Apple vs. Garmin vs. Fitbit vs. Samsung

    Smartwatches’ Accuracy in Detecting Atrial Fibrillation: Apple vs. Garmin vs. Fitbit vs. Samsung

    Key Takeaways

    1. Smartwatches from various brands are generally effective in detecting atrial fibrillation, with overall sensitivity at 95% and specificity at 97%.
    2. There are significant differences in detection capabilities among brands, with Garmin and Samsung performing best, while Fitbit lags behind.
    3. Sensitivity (ability to identify disease) and specificity (ability to identify healthy individuals) are key metrics in evaluating smartwatch performance for atrial fibrillation detection.
    4. The study is a systematic review, analyzing existing research rather than conducting new measurements, which allows for a broader evaluation of multiple devices.
    5. The research is in preprint and has not yet undergone peer review, indicating that findings may evolve with future studies and new device introductions.

    A fresh meta-analysis and systematic review, which is currently in preprint, indicates that smartwatches from different brands can effectively detect atrial fibrillation overall. We will delve into the background of this study type and the specific technical terms later. This open-access meta-analysis by Barrera et al. assessed studies with a total of 17,349 participants. The researchers measured sensitivity, specificity, and the area under the curve (AUC). The findings reveal that while there are variations in the ability to detect atrial fibrillation, the technology is generally dependable across multiple manufacturers. The sensitivity across all devices tested was 95%, and the specificity was 97%.

    Variations Among Manufacturers

    There are distinctions among different brands. For instance, Garmin Forerunner models with the relevant function report a sensitivity of 97% and a specificity of 98%, while the Apple Watch has sensitivity and specificity values of 94% and 97%, respectively. On the other hand, Fitbit is noticeably behind, with a sensitivity of 66% and a specificity of 79%. The smartwatch that offers the most precise diagnostics can be determined best by looking at the area under the curve (AUC) of the SROC (Summary Receiver Operating Characteristic), with Samsung ranking highest. However, we should not interpret the findings of this study, particularly for devices boasting sensitivity and specificity well over 90%, as a strict hierarchy that should directly guide consumer choices. Additionally, it’s not always guaranteed that both electrocardiographs and optical sensors can reliably detect atrial fibrillation, even though PPG-based systems allow for more regular or continuous monitoring.

    Understanding Sensitivity and Specificity

    Some background information might be required for interpretation and classification, along with explanations of technical jargon. In a medical-diagnostic setting, sensitivity refers to the percentage of diseases or “abnormalities” that are identified, whereas specificity denotes the proportion of healthy individuals accurately recognized as healthy. As we explained in our analysis of the Apple Watch’s blood pressure function, these two metrics are interconnected. Diagnostic techniques can be adjusted for higher sensitivity or specificity within certain boundaries, assuming the method is fundamentally appropriate. In screening procedures like atrial fibrillation detection, high sensitivity should be prioritized from the individual patient’s viewpoint. While a false-positive result could lead to unnecessary waiting at the doctor’s office and an unwarranted ECG, this is certainly a far lesser concern than the heightened mortality risk tied to undetected atrial fibrillation.

    Nature of the Study

    The study is classified as a systematic review, which means that Barrera N et al. did not conduct any measurements themselves, but rather analyzed existing studies and included them in their evaluation (or excluded them). The benefits of such studies are that they gather a considerable number of participants and assess a wider range of brands/devices. It’s important to note that this review includes various specific model versions from different manufacturers, and the number of test subjects for each specific device can vary widely. Moreover, the measurement techniques employed in the individual studies are not always consistent. The study by Barrera N et al. is still in the preprint phase and has not yet undergone peer review. Finally, the research landscape may evolve, particularly if new devices are introduced to the market.

  • Raspberry Pi Wi-Fi Chip Accurately Measures Heart Rate Without Trackers

    Raspberry Pi Wi-Fi Chip Accurately Measures Heart Rate Without Trackers

    Key Takeaways

    – Inexpensive Wi-Fi chips, like the $5 ESP32, can track heart rates as accurately as high-end devices such as the Apple Watch 10.
    – The Raspberry Pi outperformed expectations by analyzing Wi-Fi Channel State Information (CSI) data with AI algorithms for heart rate measurement.
    – Wi-Fi channel characteristics change slightly with each heartbeat and breath, allowing for accurate pulse detection through machine learning.
    – The system can measure heart rates regardless of participants’ positions, making it versatile for various settings.
    – Researchers are expanding their work to include breathing rate detection, which could aid those with sleep apnea.

    Cheap Wi-fi chips, similar to those in a $30 Raspberry Pi, can accurately measure human pulse, rivaling clinical heart rate monitors and pricey fitness trackers like the Apple Watch.

    Pulse-Fi Study Insights

    Researchers from UCSC, who led the Pulse-Fi study, found that a basic Wi-Fi network made with a $5 ESP32 chip can track heart rates as effectively as the Apple Watch 10, which is currently on sale at $359 on Amazon. The findings show that these inexpensive devices can perform on par with much costlier options.

    The Raspberry Pi’s test results were even better, as the researchers analyzed Wi-Fi Channel State Information (CSI) data through AI algorithms to determine the heart rates of over 100 participants in the study.

    How It Works

    The Wi-Fi channel characteristics, such as phase, frequency in the environment, and amplitude, change slightly with every breath and heartbeat. These tiny variations are filtered using machine learning algorithms that eliminate other factors affecting CSI, allowing the Raspberry Pi to accurately measure the pulse of all 118 participants in the research.

    Interestingly, the Wi-Fi network was capable of detecting heart rates regardless of the participants’ positions—whether they were moving, standing, sitting, or lying down.

    Development of the System

    To accomplish this, the team had to build a database from the ground up and utilize a clinical-grade oximeter as a reference device. This helped the AI algorithms learn which changes in Wi-Fi channel frequency or amplitude were associated with a heartbeat and which were due to other interferences.

    The AI system they implemented allowed for pulse detection from a greater distance, enabling casual heart rate monitoring through Wi-Fi networks using the Pulse-Fi algorithm. In addition to heart rate detection, the UCSC researchers are now also focusing on recognizing breathing rate patterns, which could benefit individuals suffering from sleep apnea.
