Quantum tunneling in graphene advances the age of terahertz wireless communications

Scientists from MIPT, Moscow Pedagogical State University and the University of Manchester have created a highly sensitive terahertz detector based on the effect of quantum-mechanical tunneling in graphene. The sensitivity of the device is already superior to commercially available analogs based on semiconductors and superconductors, which opens up prospects for applications of the graphene detector in wireless communications, security systems, radio…

Qualcomm Wins US Antitrust Lawsuit Appeal Over Chip Licensing

A U.S. appeals court on Tuesday reversed a lower court ruling against chip supplier Qualcomm in an antitrust lawsuit brought by the Federal Trade Commission. From a report: The United States Ninth Circuit Court of Appeals also vacated an injunction that would have required Qualcomm to change its intellectual property licensing practices. The decision amounted to a near complete victory for…

New ‘Spectra’ Attack Breaks the Separation Between Wi-Fi and Bluetooth

An anonymous reader quotes a report from ZDNet: Academics from Germany and Italy say they developed a new practical attack that breaks the separation between Wi-Fi and Bluetooth technologies running on the same device, such as laptops, smartphones, and tablets. Called Spectra, this attack works against “combo chips,” specialized chips that handle multiple types of radio wave-based wireless communications, such as…

Sony Builds IoT Chip With a 60-Mile Range

An anonymous reader quotes a report from Engadget: Sony is quietly launching a chip that could change how e-bikes, cars, street lamps and all kinds of other connected devices can relay information. The module, when installed on any IoT object, will allow it send data to Sony’s proprietary low-power wide area (LPWA) ELTRES network launching this fall. It can transmit up…
