how 5g makes use of millimeter waves




5g refers to the fifth generation of mobile networking standards determined by the 3gpp, the organization that sets the guidelines for every company operating in cellular communications. the official name, 5g nr, stands for new radio, and doesn't really mean anything. it'll be used the way "lte" is ...



c spire and phazr complete 5g trial with millimeter waves in mississippi




c spire, a privately-held wireless provider that serves the american south, completed a technical trial with phazr last week at c spire’s headquarters in ridgeland, miss. the goal was to test the startup’s millimeter wave base station technology, which could become a key component of future 5g n...

here's what you need to know




today, qualcomm officially announced the first 5g millimeter wave and sub-6ghz antennas for mobile devices. these antennas will help bring 5g into reality, and you’ll see them in devices soon — before the end of 2018.before we go any further, let’s first talk about what millimeter wave (mmwave...



millilabs ignores industry skepticism to build emulator for millimeter waves




the startup says it has an alternative to expensive over-the-air tests for 5g



5g bytes: millimeter waves explained




today’s mobile users want faster data speeds and more reliable service. the next generation of wireless networks—5g—promises to deliver that, and much more. right now, though, 5g is still in the planning stages, and companies and industry groups are working together to figure out exactly what ...

waves in lakes make waves in the earth




beneath the peaceful rolling waves of a lake is a rumble, imperceptible to all but seismometers, that ripples into the earth like the waves ripple along the shore.



unusual sound waves discovered in quantum liquids




ordinary sound waves—small oscillations of density—can propagate through all fluids, causing the molecules in the fluid to compress at regular intervals. now physicists have theoretically shown that in one-dimensional quantum fluids not one, but two types of sound waves can propagate. both types...



destabilized solitons perform a disappearing act




when your heart beats, blood courses through your veins in waves of pressure. these pressure waves manifest as your pulse, a regular rhythm unperturbed by the complex internal structure of the body. scientists call such robust waves solitons, and in many ways they behave more like discrete particles...

droplet explosion by shock waves, relevant to nuclear medicine




an arrow shooting through an apple, makes for a spectacular explosive sight in slow motion. similarly, energetic ions passing through liquid droplets induce shock waves, which can fragment the droplets.



columbia engineers invent breakthrough millimeter-wave circulator ic




new york, ny -- oct. 6, 2017 -- columbia engineering researchers, led by harish krishnaswamy, associate professor of electrical engineering, in collaboration with professor andrea alu's group from ut-austin, continue to break new ground in developing magnet-free non-reciprocal components in modern s...



apple granted approval to test its 5g wireless technology




however, apple is targeting millimeter-wave broadband at higher frequency and smaller wavelength bands than the spectra t-mobile and sprint are currently focusing their networks on. however, those companies and others have acquired plenty of millimeter-wave spectra of their own. millimeter-wave tech...



physicists image individual molecules by watching them absorb light




what do ships, bats and torpedoes have in common? they navigate by emitting sound waves and listening where those get absorbed or reflected. humans do the same with light waves, except that they rely on external sources like the sun for the original emission. however when looking at something as sma...



towards mastering terahertz waves?




the terahertz waves span frequency ranges between the infrared spectrum (used, for example, for night vision) and gigahertz waves (which find their application, among other, in wi-fi connections). terahertz waves allow for the detection of materials that are undetectable at other frequencies. howeve...



lariat upgrade will test dune design




in particle physics, the difference of a millimeter or two can make or break the experiment. in march, the lariat experiment began a proof-of-concept test to make sure the planned deep underground neutrino experiment (dune) will work well with that 2-millimeter difference.



alma eyes icy ring around young planetary system




an international team of astronomers using the atacama large millimeter/submillimeter array (alma) has made the first complete millimeter-wavelength image of the ring of dusty debris surrounding the young star fomalhaut. this remarkably well-defined band of rubble and gas is likely the result of exo...
