KW 29: 6G and mobile holograms, Amazon introduces smart shopping carts, Bridgestone develops flat tire warning system


6G and mobile holograms: As 5G continues to roll out, 6G research continues. Samsung is preparing for early 6G to launch two years ahead of the commonly predicted 2030 timeframe, even though both the proposed use cases and the underlying technology are currently shaky. Samsung also suggests that 6G will be needed to enable truly immersive extended reality, as next-generation XR headsets will need around 0.44Gbps throughput to power human retina-matching 16 million pixel displays. That’s more individual bandwidth than what 5G networks can guarantee. Samsung expects that mobile and larger displays will begin to display actual volumetric holograms, requiring at least 580Gbps for a phone-sized 6.7-inch display.

Amazon introduces smart shopping carts: Amazon is expanding its real-world footprint with another physical product: a shopping cart. The Dash Cart is in fact a smart version of the tried-and-true food transport vehicle. It is equipped with a touchscreen and other various hardware components to automatically detect what items a customer places inside and even how many of those items the customer has picked off the shelf. Upon checkout, the cart is taken through a special lane that checks customers out digitally without requiring a human cashier to ring them up.

Google Pixel Buds available in Germany: The so-called True Wireless In-Ear Headphones from Google are now available in Germany. Google introduced the Pixel Buds in October 2019. They can be connected particularly quickly with the fast pairing function. The integrated battery is sufficient for up to five hours of music playback, even up to 24 hours with the Qi-compatible charging case.

Xiaomi competes with Apple: Mi True Wireless Earphones 2 Basic have been launched as Xiaomi’s latest truly wireless earbuds. The new offering is essentially the affordable variant of the existing Mi True Wireless Earphones 2 that was launched in India in May. Xiaomi also offers touch controls on the earbuds that let users control the music or attend voice calls with a single tap.

Bridgestone develops flat tire warning system: Bridgestone teams up with Microsoft to develop a world-first monitory system for detecting tire damage issues in real-time. Bridgestone has developed a unique Tire Damage Monitoring System, using Microsoft Connected Vehicle Platform (MCVP). The system aims to increase road safety and reduce accidents caused by technical failure. Tire issues take four main forms: inadequate pressure, fatigue, irregular wear, and lastly, damage from curbs, potholes, or items on the road.

Defense against unwanted eavesdropping: Many devices with integrated voice assistance can unintentionally overhear conversations. A research team at TU Darmstadt has now developed a device for partners from the United States and France that can recognize when voice assistants stream audio recordings onto the internet without the consent of the users. Numerous English words were identified, which Alexa, for example, had misinterpreted as a wake-up word. The researchers built a functional prototype to counteract accidental audio transmissions.


“We were the most successful launch in the German app store ever.”
German coronavirus warn-app developer Peter Lorenz is enjoying the high download numbers despite some technical issues.


Lack of digitization in Berlin’s health departments hampers coronavirus app: The digital connection via QR code between the German government’s coronavirus warning app and Berlin’s health authorities isn’t working. People who want to report a positive Covid-19 test to the app still have to call a hotline. Certain questions are then used to verify whether the person has actually been infected. If this is the case, they will receive a confirmation on their smartphone, which can then be used to inform contact persons. This method was supposed to work automatically via QR codes, but that will still take some time in Berlin. The city’s health authorities are not yet connected to the server used to generate the QR codes.
