TEMPEST-D stands for “Temporal Experiment for Storms and Tropical Systems – Demonstration” and is a technology demonstration mission for a future cubesat constellation to provide the first ever temporal observations of cloud and precipitation processes and their evolution in time on a global scale. A mm-wave radiometer operating from 89 to 182 GHz is on […]
Tim Lee talks about 5G technology roadmap at Rising Stars Conference to students and young professionals.
Organizers: SungWon Chung, University of Southern California, Los Angeles, CA, USA Hermann Boss, Rhode & Schwartz, Munich, Germany Noriaki Kaneda, Nokia Bell Labs, Murray Hill, NJ, USA This workshop overviews the recent advancements in digital pre-distortion (DPD) and digital post-correction (DPC) techniques over a broad range of spectrum from DC to mmWave. Beyond the classical […]
KT Corp. (formerly Korea Telecom), the 2018 Winter Olympics Games’ official sponsor, has announced plans for the first big test run of networking technologies that could herald peak download rates up to 100 times as fast as today’s 4G systems, with delays as low as 1 millisecond. KT’s competitors SK Telecom and LG U+ are […]
Researchers at Chalmers University in Sweden have combined flexibility and terahertz detection into one flexible, graphene-based detector that could lead to new products such as wearable terahertz sensors for medical diagnosis. In research published in the journal Applied Physics Letters, the Chalmers researchers developed a field-effect transistor (FET) built up on a plastic substrate in […]
University of Washington (UW) researchers have developed a low-cost, long-range data-communication system that could make it possible for medical sensors or billions of low-cost “internet of things” objects to connect via radio signals at long distances (up to 2.8 kilometers) and with 1000 times lower required power (9.25 microwatts in an experiment) compared to existing […]
Low modulus, compliant systems of sensors, circuits and radios designed to intimately interface with the soft tissues of the human body are of growing interest, due to their emerging applications in continuous, clinical-quality health monitors and advanced, bioelectronic therapeutics. Although recent research establishes various materials and mechanics concepts for such technologies, all existing approaches involve […]
Silicon has been the mainstay of chips because silicon possesses a “Goldilocks” band gap of 1.1 electron Volts (eV), which makes it possible to operate integrated circuits at a low voltage, leading to reduced leakage of current. Another key feature of silicon is that it can be used to make a convenient “native” insulator, in […]
As we start looking towards more comprehensive exploration of the Moon and of Mars, the assumption is that we’re working on sending humans to the surface of those worlds. It’s going to be exponentially more difficult and dangerous than sending robots, but that’s what exploration is all about, right? There’s an article in the current […]
A wireless industry consortium is developing a new technology called MulteFire that it says delivers the high performance of 4G LTE cellular networks while being as easy to deploy as Wi-Fi routers.Rather than relying on the licensed spectrum purchased for today’s LTE service, MulteFire operates entirely in the unlicensed 5 gigahertz band. And to set […]
5G technologies are early in their development, and the business cases for them are a bit fuzzy, but wireless researchers and executives still had plenty to celebrate this week at the annual Brooklyn 5G Summit. They’ve made steady progress on defining future 5G networks, and have sped up the schedule for the first phase of […]
A world of millimeter-wave networks, laid out by computer, crisscrossing cities and into the stratosphere, where cell phone towers can be easily replaced by tethered autonomous copters—that’s the telecommunications infrastructure of the future. So says Facebook’s Yael Maguire, head of the company’s Connectivity Lab. Read more
An international team of researchers has developed a low-power gas sensor chip that can operate at room temperature, making possible the development of personal air-quality monitoring devices that we could carry around with us. In research described in the journal Science Advances, the team of researchers fabricated a chemical-sensitive field-effect transistor (CS-FET) platform based on […]
Researchers at IBM Research Alamaden have developed a new approach to measuring the magnetic field of individual atoms that for the first time gives scientists the ability to put the sensor exactly next to the atom they want to measure, providing them with a strong and direct signal of the magnetic field. The energy resolution […]
Student design competition supported by MTT-11 and MTT-9. For details, see: http://ims2017.org/technical-program/competitions/student-design The instructions can be downloaded here. Abstract: New nonlinear characterization instruments associated with advanced digital signal processing algorithms turned digital predistortion, DPD, into the distortion cancellation method of choice to relax the linearity-efficiency compromise of wireless systems. Soon after its dawn, about some […]
IEEE’s 5G wireless initiative has the goal of serving many more users with much higher transmission speeds. But with the existing cellular bands tightly packed, where does all the required additional network capacity come from? In contrast with the traditional radio-spectrum management view of scarce capacity, where a finite amount of spectrum must be divided […]
