Signals in the mmWave range require extra care and more expensive components than at sub-6 GHz frequencies. Data demands keep pushing for more bandwidth in wireless networks, and this trend will surely continue. AI, autonomous vehicles, AR/VR, and other technologies will see to that. The mmWave spectrum allocated for 5G can meet the bandwidth needs, […]
“As Silicon Labs’ most energy-efficient SoCs to date, all three will enable IoT device makers to build wireless devices for battery-optimised and battery-free devices that can harvest energy from external sources in their environments like indoor or outdoor ambient light, ambient radio waves, and kinetic motion,” said the company. Each has an Arm Cortex-M33 application […]
“ICU-10201 offers the sensitivity required for obstacle avoidance or proximity sensing, which is used frequently in robotics, drones and robot vacuum cleaners,” according to the company. “The sensor provides millimeter-accurate range measurements to targets at distances up to 1.7m, in any lighting condition including full sunlight, independently of the target’s color and optical transparency, like […]
Structure of SOT spin-LED. Credit: Nature (2024). DOI: 10.1038/s41586-024-07125-5 Scientists have used electrical pulses to manipulate magnetic information into a polarized light signal, a discovery that could revolutionize long-distance optical telecommunications, including between Earth and Mars. The breakthrough, described in a study published in Nature, involves the field of spintronics, which aims to manipulate the […]
Integrated communications and sensing at mmWave and sub-THz frequencies could add location detection that helps avoid accidents among pedestrians, bicycles, and vehicles. With the 5G commercial rollout well underway, users can now use its capabilities. Even so, the telecom industry is laying the groundwork for the next generation of cellular communications. 6G will use many […]

Its 235GHz antennas and the core active components are integrated on a single IC, and across a desktop it measures the range to a target with sub-mm accuracy, even if the object is moving at 600m/s – twice the speed of sound. These core components implement a ‘self-injection-locking’ oscillator, which exploits the sometimes undesirable effect […]
Thin umbilical cables to the scull tend to be the answer. These cables need to be very flexible as the brain is fixed within the skull, but rather ‘floats’ in liquid (cerebrospinal fluid – ‘CSF’) within the skull cavity. The gap is a few millimeters and the cable needs cross this while allowing for relative […]
Do you want assurance that cameras embedded in everyday devices don’t spy on you? Then you should check for cameras, SD card slots, and Wi-Fi-connections. We reviewed two devices that help to find those lurking spies. While discovering a hidden camera in an Airbnb, VRBO, or hotel is rare, there have been reports of travelers […]
