Energy-efficient LTE modem with speeds up to 450 Mbps

06.12.2014

Qualcomm Incorporated (NASDAQ: QCOM) today announced the release of the Qualcomm Gobi 9x45 360th generation multi-mode LTE modem and the 3100nd generation Qualcomm RFXNUMX Envelope Tracker QFEXNUMX energy tracker.

Both products are designed to provide high speed data download from the network, fast application performance, as well as improve the energy efficiency of the device and optimize energy consumption. New products are currently being tested by Qualcomm partners, and deliveries to the market are scheduled for 2015.

In addition to general improvements that optimize power consumption and PCB space, the 9x45 modem is the first Category 10 solution to support carrier aggregation worldwide, providing up to 450 Mbps downlink and up to 100 Mbps uplink. c, aggregating the frequencies of the TDD and FDD spectrum.

The modem is based on the second generation 20nm process technology and provides aggregation of up to three frequencies in the 60 MHz band on the downlink and up to two frequencies in the 40 MHz band on the uplink. The 9x45 modem integrates all major cellular standards including DC-HSPA, EVDO, CDMA 1x, GSM and TD-SCDMA, supports all major RF bands and their combinations, and provides geolocation in GPS, Beidou, GLONASS and Galileo systems. In addition, the new modem supports LTE Broadcast, VoLTE and LTE Dual SIM by default.

The layout of the QFE3100 has been optimized to reduce PCB area by 30%, making the chip more energy efficient than previous generation solutions.

The use of a 9x45 modem allows mobile device manufacturers to use the maximum available private spectrum, provide high data rates and greater flexibility in implementing network architecture.

Qualcomm's new solution meets market demands for more efficient power consumption and thinner devices, bringing diversity to mobile solutions. For consumers, this means up to 6x faster upload speeds and up to XNUMXx peak download speeds compared to LTE Category XNUMX devices. In addition, the advanced modem improves application responsiveness and better connectivity to LTE-A coverage.

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Implanted brain stimulator 30.04.2024

In recent years, scientific research in the field of neurotechnology has made enormous progress, opening new horizons for the treatment of various psychiatric and neurological disorders. One of the significant achievements was the creation of the smallest implanted brain stimulator, presented by a laboratory at Rice University. Called Digitally Programmable Over-brain Therapeutic (DOT), this innovative device promises to revolutionize treatments by providing more autonomy and accessibility to patients. The implant, developed in collaboration with Motif Neurotech and clinicians, introduces an innovative approach to brain stimulation. It is powered through an external transmitter using magnetoelectric power transfer, eliminating the need for wires and large batteries typical of existing technologies. This makes the procedure less invasive and provides more opportunities to improve patients' quality of life. In addition to its use in treatment, resist ... >>

The perception of time depends on what one is looking at 29.04.2024

Research in the field of the psychology of time continues to surprise us with its results. Recent discoveries by scientists from George Mason University (USA) turned out to be quite remarkable: they discovered that what we look at can greatly influence our sense of time. During the experiment, 52 participants took a series of tests, estimating the duration of viewing various images. The results were surprising: the size and detail of the images had a significant impact on the perception of time. Larger, less cluttered scenes created the illusion of time slowing down, while smaller, busier images gave the feeling of time speeding up. Researchers suggest that visual clutter or detail overload can make it difficult to perceive the world around us, which in turn can lead to faster perception of time. Thus, it was shown that our perception of time is closely related to what we look at. Larger and smaller ... >>
