Here’s an example of a product that’s impossible to grade with a single score: the Audio-Technica DSR9BT headphones. They are unique both technologically and practically, providing the best sound out of any wireless headphone yet, but only in limited circumstances. They outperform every other pair of Bluetooth headphones when listened to in a quiet environment, but they fail miserably when taken out into the din of a busy street. I’ve been excited about the $549 DSR9BTs since I first heard Bjork’s Homogenic through them at CES in January. The soundstage and stereo separation from these nominally closed-back headphones are exceptional, and Bjork’s voice is recreated with affecting fidelity. Pressing play on these cans is going to wow most listeners, because they just don’t sound like wireless headphones. In all of my testing and experience with headphones, I’ve never heard anything so pure and undistorted without a wire attached. The DSR9s … [Read more...] about The best-sounding Bluetooth headphones are unfit for mobile use
A New York City resident was ordered to turn off his bitcoin miner after the Federal Communications Commission discovered that it was interfering with T-Mobile's wireless network. After receiving a complaint from T-Mobile about interference to its 700MHz LTE network in Brooklyn, New York, FCC agents in November 2017 determined that radio emissions in the 700MHz band were coming from the residence of a man named Victor Rosario. "When the interfering device was turned off the interference ceased," the FCC's enforcement bureau told Rosario in a "Notification of Harmful Interference" yesterday. "You identified the device as an Antminer S5 Bitcoin Miner. The device was generating spurious emissions on frequencies assigned to T-Mobile's broadband network and causing harmful interference." The FCC told Rosario that continued interference with T-Mobile's network while operating the device would be a violation of federal laws "and could subject the operator to severe penalties, including, but … [Read more...] about Bitcoin miner in NYC home interfered with T-Mobile network, FCC says

Total shipments of mobile phone displays, including thin-film transistor liquid crystal display (TFT LCD) and active matrix organic light-emitting diode (AMOLED) panels, reached 2.01 billion units in 2017, up 3 percent from 2016, according to preliminary estimate from business information provider IHS Markit (Nasdaq: INFO).In the growing mobile phone display market, shipments of low-temperature-poly-silicon (LTPS) TFT LCD panels, which realize high-resolution images, increased by 21 percent to 620 million units in 2017 compared to the previous year. Shipments of amorphous silicon (a-Si) TFT LCD mobile phone panels declined 4 percent to 979 million units during the same period. Even though shipments of AMOLED panels jumped in the second half of 2017 thanks to the launch of the iPhone X, combined with the weak demand in the first half, its shipments were up just 3 percent to 402 million units in 2017.In the smartphone-use LTPS TFT LCD market, Tianma, a leading small and medium panel … [Read more...] about Chinese panel makers catching up fast in LTPS LCD panel shipments for mobile phones
Microprocessors, which first appeared in the early 1970s as 4-bit computing devices for calculators, are among the most complex integrated circuits on the market today. During the past four decades, powerful microprocessors have evolved into highly parallel multi-core 64-bit designs that contain all the functions of a computer’s central processing unit (CPU) as well as a growing number of system-level functions and accelerator blocks for graphics, video, and emerging artificial intelligence (AI) applications. MPUs are the “brains” of personal computers, servers, and large mainframes, but they can also be used for embedded processing in a wide range of systems, such as networking gear, computer peripherals, medical and industrial equipment, cars, televisions, set-top boxes, video-game consoles, wearable products and Internet of Things applications. The recently released 2018 edition of IC Insights’ McClean Report shows that the fastest growing … [Read more...] about Mobile system-on-chip designs, embedded processing lift MPU market
