  • CSR Debuts First SiRFstarV Chip Optimized for Mobile Devices

    CSR plc has introduced the SiRFstarV 5t tracker, the first SiRFstarV architecture product optimized to deliver continuous, highly accurate location awareness to the latest generation of smartphones, tablets, and other mobile devices. The quad-GNSS SiRFstarV 5t tracker is the first SiRFstarV device to offer exclusive CSR adaptive continuous tracking power management technology, which CSR said offers significant power savings for extended battery life, and also includes MEMS inputs, LTE immunity, enhanced active jammer removal and other SiRFstarV features.

    The SiRFstarV 5t is in use by LG Electronics for its first quad-core smartphone, the LG Optimus 4X HD, which takes advantage of the device’s GLONASS support and high sensitivity, CSR said.

    “With GPS, GLONASS, Galileo, and Compass system capabilities, our new power-saving technology and the other SiRFstarV features, the SiRFstarV 5t tracker is perfect for mobile device OEMs looking to create new products that take location and navigation to the next level for an enhanced user experience,” said Dave Huntingford, director of location product line marketing at CSR. “We believe the SiRFstarV 5t again demonstrates CSR leadership in providing best-in-class location solutions that meet or exceed the demanding requirements of smartphone OEMs and operators.”

    Optimized for size- and power-constrained applications, the SiRFstarV 5t boasts a number of enhanced SiRFstarV architectural features — from quad-GNSS support and MEMS-aiding, to improved sensitivity and interference rejection to small size and low BOM count — that result in location performance and power consumption improvements, reduced package size, easier integration and lower-cost implementation, CSR said. The SiRFstarV 5t supports A-GPS and A-GLONASS in MSA and MSB modes, and has been tested for all major carrier requirements, including SUPL1.0 and SUPL2.0, and offers improved 3GPP acquisition and tracking margins. SiRFInstantFix extended ephemeris technology for GPS and GLONASS is also supported.

    The SiRFstarV 5t supports all four major GNSS. With its 24 additional satellites, GLONASS provides a valuable augmentation to GPS and enables the SiRFstarV 5t to boost location performance, especially in urban canyons, for the most demanding applications by increasing service availability, reducing observation time and making solutions more precise. The SiRFstarV 5t additionally supports Galileo and Compass systems, when they become available, with a software upgrade for even greater performance and ensured compliance to existing and future requirements of the world’s major GNSS systems.

    The SiRFstarV 5t introduces CSR’s exclusive TricklePowerII technology, an improved intelligent power management system that can deliver significant power savings compared to other location solutions for continuous 1-Hz navigation. TricklePowerII continually measures the strength of the available satellite signals and dynamically adjusts the chip’s power consumption to just the right amount to achieve optimal location performance without wasting power. With many new mobile devices including MEMS (micro-electro-mechanical systems) sensors, the SiRFstarV 5t is able to utilize data from these sensors to improve navigation accuracy and reduce power.

    The SiRFstarV 5t has been designed from the ground up to provide superior immunity to interference from LTE (long-term evolution) radio signals, giving mobile device manufacturers confidence in its ability to coexist in their designs with LTE, CSR said. Coexistence of LTE with GPS, GLONASS, and other GNSS signals is critical for continuous location awareness and use of location-based services, and CSR has implemented a number of mechanisms to boost immunity to LTE interference in the SiRFstarV 5t.

    The SiRFstarV 5t also includes improved active jammer removal, a unique CSR technology first introduced with the SiRFstarIV architecture, which improves location performance by continually tracking and eliminating radio interference from up to eight sources, a critical requirement when GNSS devices are in close proximity to other electrically noisy devices like those found in a mobile handset.

    The complete CSR solution includes SiRFNav software running on the host CPU to calculate the precise position, velocity and time and provide complete control of GNSS operation, including navigation, assistance and nav-aiding. The solution requires minimal OS-dependent host system loading during tracking, simplifying system integration, and supports a wide variety of CPUs and operating systems.

  • Preparations Move Forward for Next Galileo Launch

     


    Galileo Flight Model #3 (FM3) is readied for the satellite’s fit check on the dispenser that will carry it and FM4 in a parallel arrangement on Soyuz’ next launch. The silver-colored dispenser is partly visible behind two mission team members during this activity in the Spaceport’s S1B payload preparation building.

     

    Both Galileo navigation satellites for Arianespace’s third Soyuz flight from the Spaceport are now in French Guiana, marking a new milestone for this mission scheduled in the second half of 2012, according to Arianespace.

    The Flight Model #4 (FM4) satellite arrived Friday at Félix Eboué International Airport near the capital city of Cayenne, delivered by a chartered Ilyushin Il-76TD cargo jetliner.

    Its FM3 co-passenger remains busy in the Spaceport’s S1B payload preparation building — completing its fit check with the dispenser for the dual-satellite payload arrangement on Soyuz. The dispenser was developed for Arianespace by RUAG Space, and carries the satellites in a parallel arrangement.

    These two spacecraft will join another pair of Galileo satellites launched by Arianespace in October 2011 on Soyuz’ maiden flight from French Guiana. All four are In-Orbit Validation platforms that will enable European industry to validate prototype Galileo-based receivers and services using actual satellite signals, while also allowing performance assessments of the ground system that will maintain the Galileo system’s precision.

    Arianespace is responsible for deploying the entire Galileo constellation, to be composed of 30 satellites in orbit as an independent global satellite navigation system for Europe.

    Galileo launches began with the 2005 and 2008 orbiting of two experimental satellites — GIOVE-A and GIOVE-B — carried on Soyuz vehicles operated from Baikonur Cosmodrome in Kazakhstan by Arianespace’s Starsem affiliate. It was followed by October 2011’s maiden Soyuz launch from French Guiana with the constellation’s first two operational satellites.

    Arianespace is able to use a mix of both its medium-lift Soyuz and heavy-lift Ariane 5 launchers in deploying the full Galileo system, demonstrating the company’s flexibility in orbiting satellite constellations.

  • Smartphones See Accelerated Rise to Dominance

    Driven by increased demand from developed regions for high-end models, along with an unexpectedly strong push from emerging economies for lower-cost products, smartphones are expected to rise to account for the majority of global cellphone shipments in 2013—two years earlier than previously predicted, according to research firm IHS iSuppli.

    Smartphone shipments in 2013 are forecast to account for 54 percent of the total cellphone market, up from 46 percent in 2012 and 35 percent in 2011, according to an IHS iSuppli Wireless Communications Market Tracker Report from information and analytics provider IHS. The year 2013 will mark the first time that smartphones will make up more than half of all cellphone shipments.

    “This represents a major upgrade for the outlook compared to a year ago, when smartphones weren’t expected to take the lead until 2015,” said Wayne Lam, senior analyst for wireless communications at IHS. “Over the past 12 months, smartphones have fallen in price, and a wider variety of models have become available, spurring sales of both low-end smartphones in regions like Asia-Pacific, as well as midrange to high-end phones in the United States and Europe. The solid expansion in both shipments and market share this year of smartphones will make them the leading type of mobile phone for the first time, and shipment growth in the double digits will continue for the next few years.”

    By 2016, smartphones will represent 67.4 percent of the total cellphone market.
    Feature Phone Finale
    While still accounting for less than 50 percent of the market this year, smartphones will become the single largest cellphone segment by the end of 2012, surpassing feature phones, reported IHI.The rise of smartphones to a plurality share this year means a fall from grace for feature phones, which are a grade above the most basic, low-cost entry-level phones but lack the sophisticated engineering and abundant functionality of smartphones. Feature phones commanded the wireless market as late as last year with 46 percent market share, but their portion will decrease to 41 percent this year, setting a trend of irreversible decline and progressive weakening in their numbers.

    By 2016, feature phones will be confined to a market share of 28 percent—less than half the share of smartphones by that time.

    A third type of phone, the entry-level and ultra-low-cost handset, will occupy the bottom tier of the market with approximately 14 percent share this year and end up with just 4.2 percent share by 2016.

    Wireless Handsets Get Smart 

    As smartphones become ever more popular and affordable, they will become the focal point of the handset industry, IHS believes. Smartphones will deliver multifunctional capabilities that enhance experiences, while at the same time providing a hardware venue toward increasing average revenue per user, made possible through the extensive data use of smartphone owners.

    Growth of the mobile applications development industry, which turns out innumerable applications on a variety of smartphone platforms, will also help maintain the continuing importance of the smartphone segment.

    Market Segments into Low-end vs. Midrange/High-end Smartphones

    The smartphone market is, in fact, made up of two segments—the midrange to high-end smartphone on the one hand, and low-end smartphones on the other. Already, manufacturers are introducing affordable low-end smartphones equipped with lower memory densities and a more limited feature set into developing countries and emerging markets, encouraging in these regions the use of data plans, which drive greater revenue. Low-end smartphone users will likely be first-time smartphone consumers, and will represent 43 percent of the total smartphone market by 2016.

    In comparison, the midrange to high-end smartphone segment consists of users in the developed countries or in the more industrialized urban areas of some developing nations. This group of smartphone users will continue to outnumber their low-end smartphone counterparts, with more than 700 million midrange to high-end smartphone users forecast by 2016.

    Apple and Google, now the two leading smartphone platforms, are the leaders in the space.

    The intense competition in smartphone platforms has by now resulted in a few casualties, including Symbian from Nokia and WebOS from Palm. No longer will hardware capabilities be the sole determinant of success for smartphones moving forward, IHS believes, as victory in the marketplace will now also rely on many other important factors. These include software capability, a sleek and intuitive user interface, the variety of available applications, strong support from the developer community, and the strength and seamlessness of vertical integration.

    Samsung of South Korea became the overall worldwide leader in handsets during the first quarter, displacing Nokia of Finland, which had occupied the top spot for well over a decade and is now at No. 2. U.S.-based Apple, China’s ZTE and LG Electronics, also of South Korea, rounded out the Top 5, accounting for 75.5 percent of all handset shipments—not just smartphones—during the first quarter, up marginally from 74.7 percent in the fourth quarter last year.

  • Rice University Announces New Mobile Technology they claim Dramatically Increases Data Capacity

    Researchers from Rice University unveiled a new multi-antenna technology that could help wireless providers keep pace with the voracious demands of data-hungry smartphones and tablets. The technology aims to dramatically increase network capacity by allowing cell towers to simultaneously beam signals to more than a dozen customers on the same frequency.

    Details about the new technology, dubbed Argos, were presented at the Association for Computing Machinery's MobiCom 2012 wireless research conference in Istanbul. Argos is under development by researchers from Rice, Bell Labs and Yale University. A prototype built at Rice this year uses 64 antennas to allow a single wireless base station to communicate directly to 15 users simultaneously with narrowly focused directional beams.

    Thanks to the growing popularity of smartphones and other data-hungry devices, the demand for mobile data is expected to grow 18-fold within the next five years. To meet demand, wireless carriers are scrambling to boost network capacity by installing more wireless base stations and shelling out billions of dollars for the rights to broadcast on additional frequencies.

    In tests at Rice, Argos allowed a single base station to track and send highly directional beams to more than a dozen users on the same frequency at the same time. The upshot is that Argos could allow carriers to increase network capacity without acquiring more spectrum.

    "The technical term for this is multi-user beamforming," said Argos project co-leader Lin Zhong, associate professor of electrical and computer engineering and of computer science at Rice. "The key is to have many antennas, because the more antennas you have, the more users you can serve."

    Zhong said the theory for multi-user beamforming has been around for quite some time, but implementing technology has proven extremely difficult. Prior to Argos, labs struggled to roll out prototype test beds with a handful of antennas.

    "There are all kinds of technical challenges related to synchronization, computational requirements, scaling up and wireless standards," he said. "People have really questioned whether this is practical, so it's significant that we've been able to create a prototype that actually demonstrates that this works."

    Argos presents new techniques that allow the number of antennas on base stations to grow to unprecedented scales. The Argos prototype, which was built by Rice graduate student Clayton Shepard, uses an array of 64 antennas and off-the-shelf hardware — including several dozen open-access test devices called WARP boards that were invented at Rice's Center for Multimedia Communications. In tests, Argos was able to simultaneously beam signals to as many as 15 users on the same frequency. For wireless carriers, that performance would translate to more than a six-fold increase in network capacity. Zhong said the base-station design can be scaled up to work with hundreds of antennas and several dozen concurrent users, which would result in much higher capacity gains.

    "There's also a big payoff in energy savings," Shepard said. "The amount of power you need for transmission goes down in proportion to the number of antennas you have. So in Argos' case, we need only about one-sixty-fourth as much energy to serve those 15 users as you would need with a traditional antenna."

    Zhong and Shepard said Argos is at least five years away from being available on the commercial market. It would require new network hardware and a new generation of smartphones and tablets. It might also require changes in wireless standards. Those are big hurdles, but Zhong said the potential benefits of multi-user beamforming technology make it a very likely next big step for the wireless industry.

    "The bandwidth crunch is here, and carriers need options," Zhong said. "They're going to pay close attention to any new technologies that may allow them to serve more customers with fewer resources."

    Research co-authors include Hang Yu and Narendra Anand, both of Rice; Li Erran Li and Tom Marzetta, both of Bell Labs; and Yang Richard Yang of Yale University. The research was supported by the National Science Foundation, Bell Labs, Alcatel Lucent and the Air Force Office of Sponsored Research.
