KW 14: Cellular waves can be used as an energy source, How the pandemic is changing the IoT market, LG Electronics exits the smartphone business


Cellular waves can be used as an energy source: Researchers at the Georgia Institute of Technology have devised a novel way to harvest 5G frequencies at 28GHz to power IoT nodes, in effect turning them into a wireless power grid. The Rotman lens-based rectifying antenna (dubbed the rectenna) was developed such that it could be produced on a flexible substrate with 3D printing, and thus easily incorporated into an IoT node. The Rotman lens is key for beamforming networks and is frequently used in radar surveillance systems to see targets in multiple directions without physically moving the antenna system. However, the researchers point out, to harvest sufficient power to supply low-power devices at long ranges, large aperture antennas as needed. The drawback with large antennas, unfortunately, is that they have a narrowing field of view. This prevents their operation if the antenna is widely dispersed from a 5G base station.

German Internet Association (eco) calls for higher security standards for IoT: According to the German Internet Association (eco), a German security seal for IoT devices based on the ETSI EN 303 645 standard could improve security in the Internet of Things (IoT) as well as transparency for consumers. For this reason, the association has formulated five requirements, because currently all too often the security of the networked devices that are already in existence is left by the wayside. Even if users could adapt their devices accordingly, it is important that the devices are appropriately secured at the factory, especially since laypeople can hardly assess whether their consumer IoT products are safe or unsafe.

How the pandemic is changing the IoT market: Covid-19 has caused a delay of one year in the growth of devices with Bluetooth, according to the Bluetooth Market Update 2021, which was published by the Bluetooth Special Interest Group (SIG). Annual shipments of Bluetooth enabled devices will increase from four billion in 2020 to over six billion in 2025.

LG Electronics exits the smartphone business: LG Electronics, the South Korean giant – has exited the smartphone industry following weeks of speculation. LG’s exit makes it the first major player to quit the smartphone business amid mounting losses. LG has a notable presence in the US, with a market share of 9% in the December 2020 quarter, according to Counterpoint Research. Its exit will allow Apple and Samsung to gobble up even more market share.

Pandemic fuels growth in chip manufacturing in Saxony: Delivery bottlenecks in semiconductor production are helping the East German economy: In Dresden, for example, three well-known semiconductor manufacturers are planning investments worth billions. The global demand for computer chips is growing because they are essential for networked devices. The expansion of production in the German state of Saxony began a little more than ten years ago. According to the industry association “Silicon Saxony” there are now around 2,300 companies with more than 65,000 employees and Saxony has advanced to become an important location for European microelectronics.

Free developer kits from Thomas-Krenn: The server manufacturer Thomas-Krenn provides IoT developers with free developer kits to implement IoT projects with LoRaWAN technology. If you want to participate, you can apply – preferably with a description of the project – because the number of free kits is limited. Thomas-Krenn would like to learn more about possible applications through the campaign.
