Broadcom releases satellite-constellation location IC

8521338394_ec9d0e1f06_c Broadcom Corporation has introduced a Global Navigation Satellite System (GNSS) chip, designated BCM47531, that generates positioning data from five satellite constellations simultaneously (GPS, GLONASS, QZSS, SBAS and BeiDou), totaling 88 satellites. The newly added Chinese BeiDou constellation increases the number of satellites available to a smartphone, enhancing navigation accuracy, particularly in urban settings where buildings and obstructions can cause interference.

The company’s new GNSS SoC is based on its widely deployed architecture that reduces the “time to first fix” (TTFF) and allows smartphones to quickly establish location and rapidly deliver mapping data. The SoC also features a tri-band tuner that enables smartphones to receive signals from all major navigation bands (GPS, GLONASS, QZSS, SBAS, and BeiDou) simultaneously.

The BCM47531 platform is available with Broadcom’s Location Based Services (LBS) technology that delivers satellite assistance data to the device and provides an initial fix time within seconds, instead of the minutes that may be required to receive orbit data from the satellites themselves.

The BCM47531 brings a number of powerful features to the table:

  • Simultaneous support of five constellations (GPS, GLONASS, QZSS,SBAS and BeiDou) allows for position calculations based on measurements from any of 88 satellites.
  • Broadcom's tri-band tuner brings the ability to receive all navigation bands, GPS (which includes QZSS and SBAS), GLONASS and BeiDou simultaneously to the commercial GNSS market without having to reconfigure and hop between bands.
  • Utilizes BeiDou signals for up to 2x improved positioning accuracy.
  • Best-in-class Assisted GNSS (AGNSS) data available worldwide from Broadcom's hosted reference network.
  • Allows a device to interchangeably use the best signal from any satellite regardless of the constellation, ensuring better accuracy in urban and mountainous environments.
  • Features advanced digital signal processing for interference rejection that enables satellite signal search and tracking during LTE transmission.
  • Leverages Broadcom's connectivity solutions including Wi-Fi, Bluetooth Smart, Near Field Communications (NFC), Instant Messaging System (IMES) and handset inertial sensor data for best indoor/outdoor location.

Nanobubbles with graphene - diamond substrate

Observing HighPressure Chemistry in Graphene Bubbles<br /> Scientists at the National University of Singapore have come up with a way to trap liquids inside nanoscale bubbles made of graphene, topping a diamond substrate. "We discovered a way to bond the two materials together by heating the diamond to its reconstruction temperature where its surface hydrogen is desorbed," said Kian Ping Loh, the research team leader.

The team were able to use these graphene bubbles as high pressure chemical reactors to perform reactions that are normally forbidden, such as fullerene polymerisation.

Anvil cells generate extremes of pressure by applying a force over as small an area as possible. As one of the thinnest elastic membranes in existence, graphene can be strain-engineered to form nanometre bubbles; spaces small enough to reach extremes of pressure when heated.2 Thanks to the bubbles’ impermeability to almost any fluid, this implies that graphene could be used to seal and pressurise fluids in nano-sized liquid cells.

China used more than half of world's ICs in 2012

0023ae82ca0f13af1f6d03 China's semiconductor use has hit a record high and accounts for more than half of the global market, but the country is overly dependent on foreign suppliers for relevant products, according to a PricewaterhouseCoopers report issued on Thursday.

With an 8.7 percent growth in 2012, China's semiconductor use was 52.5 percent of the total worldwide, said a PwC report titled China's Impact on the Semiconductor Industry - 2013 Update. Semiconductors act as an engine now driving an increasing amount of the technology in people's lives.

The growth in Chinese semiconductor use is a remarkable contrast to the global market for semiconductors, which experienced an overall decline of3 percent in 2012, the report said.

China is expected to continue its domination of semiconductor purchasing in the foreseeable future with its market share possibly reaching 60 percent by 2017,Raman Chitkara, PwC's global technology and semiconductor leader, said in an interview with China Daily.

"One of the major reasons why China has grown so big in semiconductor consumption is that the country isrising to become the world's capital of electronic manufacturing," Chitkara said.

India Plans To Build 2 Wafer Fabs

FAB_INDIA The government of India on Thursday approved "in principle" a plan to construct and equip two wafer fabrication facilities in the country, in a move designed to reduce India's reliance on imported semiconductors. Two consortia will go ahead with the twin fab projects. One is led by STMicroelectronics, an integrated device manufacturer, and the other is spearheaded by Tower Semiconductor, a silicon foundry. These companies will add their names to list of VLSI companies in India and boost the manufacturing capability.
"The Cabinet has given in-principle approval for setting up of semiconductor wafer fabrication manufacturing facilities," Information and Broadcasting Minister Manish Tewari told reporters after a meeting of the Union Cabinet, chaired by Prime Minister Manmohan Singh.
After considering proposals from two consortia, the government took the decision. The government received proposals from two consortiums to set up chip fabrication units in the country. One was led by Israel's Tower Jazz and the other was led by Geneva–based chipmaker STMicroelectronics.
Israel-based foundry chipmaker Tower Semiconductor Ltd, which operates under the brand name TowerJazz, partnered with IBM and Indian infrastructure conglomerate Jaypee Associates to build and operate a 300mm chip facility in India. On the other hand, STMicroelectronics partnered with Hindustan Semiconductor Manufacturing Corp. (HSMC).
Welcoming the government's decision, India Electronics & Semiconductor Association (IESA) President PVG Menon said, "The IESA deems the fab a highly strategic game changer for India. Some of the world's leading economies including the USA, France, Germany, Ireland, Japan, Singapore, Taiwan and China besides a number of developing economies like Malaysia and Israel have their own fabs. These fabs continue to contribute significantly to the growth and development of the economy of their respective countries and we hope that this would be the case in India as well."

Cisco’s nPower chips for moving data at 400 Gbps

cisco_networking_chip Semiconductors continue to advance, as a slew of announcements by Intel and Apple’s new A7 processor showed this week. But don’t forget about Cisco Systems.

The biggest provider of routing and switching systems has long retained the capability to design specialized processors for its hardware, as well as turn to off-the-shelf chips from commercial suppliers where that makes the most sense. Now Cisco designers have come up with another singular piece of home-grown silicon.

It’s a new product line called the nPower, and Cisco says the chips can pump as much as 400 gigabits of data per second. By contrast, the company’s prior technology could handle 140 gigabits and required more than one chip, Cisco says. The new capacity translates into hundreds of millions of transactions per second.

To what end? Of course, computer and smartphone users will continue to watch more YouTube videos and the like. But Surya Panditi, Cisco’s senior vice president and general manager of engineering, says a key driver for the technology is a coming change in the nature of network traffic.

Microsoft To Acquire Nokia's Devices And Services

nokia-lumia-800 Nokia, once a world leader in the mobile phone market, has had a tough few years and attempts by the company to join in on the smartphone explosion did not go well.

Nokia has seem somewhat of a resurgence lately with a series of high quality smartphones on the Windows Phone platform. Many of the phones such as the Lumia 928, 928 and 1020 with it's 41 megapixel are excellent devices and offer a real choice for anyone wanting to escape the ecosystems of Apple and Android. In fact the majority of users who actually try their Windows Phones quickly find that they enjoy the very different experience they have had with their previous smartphones. The problem for Nokia and Microsoft was getting users to even think about separating from their iPhone or Android device. 

According to the companies' press releases, 32,000 people will transfer across Microsoft, including 4,700 people in Finland and 18,300 employees directly involved in product manufacture. If you thought it was only the Windows Phone component of the phone business, you'd be wrong: Microsoft will also take into ownership Nokia's Asha range of feature phones. Patent-wise, Microsoft gets 10-year non-exclusive license to its Finnish partner's library of ideas and "reciprocal rights" to use Microsoft patents within its HERE mapping services. While Microsoft will be able to use the Nokia branding on its products, the Finnish company will now focus on its mapping, infrastructure and advanced tech arms.

In 2011, after writing a memo that said Nokia lacked the in-house technology and needed to jump off a "burning platform", Elop made the controversial decision to use Microsoft's Windows Phone for smartphones, rather than Nokia's own software or Google's (GOOG.O) ubiquitous Android operating system.

The deal will see Microsoft taking full control over Nokia's Smart Devices and Mobile Phones business units, which produce the Lumia family of smartphones and low-cost featurephones respectively. Nokia, meanwhile, retains its telecommunications hardware business Nokia Siemens Networks, Here location-based services arm, and its patent portfolio under the Advanced Technologies division. These patents are to be licensed to Microsoft for at least a ten-year period, the agreement states.

The acquisition will truly allow  Microsoft to enter the market in direct competition with its Windows Phone licensees. It's a move that was first telegraphed by the launch of the Surface family, which put the company in direct competition with third part manufacturer's in the Windows 8 and Windows RT tablet markets.
Nokia first started producing phones back in 1996 and for many years they were one of main innovators of smartphones. Of course the release of the iPhone in 2007 and the emergence of Android devices began to strangle Nokia. During the past couple of years Microsoft has provided a kind of life boat to Nokia with their Windows Phones and now it looks like Microsoft has taken over the reins entirely.
Time will tell for both Nokia and Microsoft, but at this very early point I believe it is a good move for both companies and consumers.
