Industry Alliances Collaborate on Internet of Things

The IPSO Alliance, which promotes IP for smart object communications, has formed partnerships with the IPv6 Forum and the ZigBee Alliance to more quickly accelerate the adoption of IP networked devices for use in energy, consumer, healthcare and industrial applications, often referred to as the "Internet of Things."

Specifically, IPSO and the ZigBee Alliance will collaborate on wireless home area networks (HAN) using the ZigBee IP specification and the ZigBee Smart Energy standard. The two alliances will work on expanding HANs by using IP technology, which will give utilities more flexibility in future Smart Grid deployments.

IPSO and the IPv6 Forum will promote a common platform of interoperability based on the IPv6 Ready Logo Program and drive deployment of Internet of Things based on IPv6. Forum members will jointly benefit from this awareness and interop initiative in sharing essential knowledge in their key events and in seeking and designing new joint initiatives on a worldwide basis.

"Having the support of two industry influences like the ZigBee Alliance and IPv6 Forum validates the demand for IP solutions in the market," said Geoff Mulligan, chairman of the IPSO Alliance. "We continue to see IP becoming the solution of choice for enabling communication for smart objects."http://www.zigbee.org

Each Ethernet Service Location is an Ethernet serviceable physical location/address, readily searchable, for example, via the CENX Market application.

Vitesse Debuts 65nm EcoEthernet SparX-III Silicon

Vitesse Semiconductor introduced its new SparX-III family of Gigabit Ethernet (GE) switching silicon designed for green-enabled Ethernet SMB and enterprise equipment with substantially lower power consumption and higher density.

The launch includes a two chip 25-port GE switch solution that can be paired with Vitesse's recently launched SimpliPHY 12-port Gigabit Ethernet PHY with dual media copper and fiber support. Both devices feature Vitesse's EcoEthernet 2.0 technology, which offers energy efficiency capabilities such as a "PerfectReach" intelligent cable length algorithm, "ActiPHY" automatic link-power down, as well as IEEE 802.3az idle power savings.

Leveraging Vitesse's 65-nm technology, the SparX-III family delivers power dissipation of <400mW/port for 1000BASE-T copper and below 50 mW/port for fiber. This eliminates the need for a cooling fan, reducing cost and noise, and increasing system reliability. In addition, customers leverage their hardware and software investment for 16- and 10-port GE switches using the pin-compatible VSC7421 and VSC7420.

SparX-III also provides an innovative low latency architecture, which improves network performance for time-sensitive applications like IPTV, VoIP, IP conferencing, and gaming. Other new built-in features such as hardware network loop detect and an overheat protection functionality allow ODMs and OEMs to further augment system reliability.

Avago Readies Amplifiers for Cellular and LTE Base Stations

Avago Technologies announced two next generation, low noise amplifiers (LNAs) for cellular infrastructure base station applications, such as transceiver radio cards, tower mounted amplifiers (TMAs), combiners, repeaters and remote/digital radio heads.

Avago said its designs are optimized for ensuring best signal quality in crowded spectrum, where receiver sensitivity is one of the most critical requirements. Proper LNA selection, in particular the first-stage LNA, greatly affects the BTS receiver sensitivity performance. Low noise figure is a key design goal. Avago will offer a noise figure of 0.48 dB at 1900 MHz.

Another key design factor is linearity, which affects the receiver's ability to distinguish between closely spaced wanted and spurious signals. Third order intercept, OIP3, is used to specify linearity. At 1900 MHz and typical operating condition of 5 V/51 mA, Avago's proprietary GaAs Enhancement-mode pHEMT process technology gives a noise figure of 0.48 dB and an OIP3 of 35 dBm. At 2500 MHz and typical operating condition of 5 V/56 mA, the noise figure is 0.59 dB and OIP3 is 35 dBm. With a low NF and high OIP3, the new Avago LNAs offer more design margin for the BTS receiver path than previous amplifiers.

Nokia and Yahoo! Form Global Strategic Alliance

Yahoo! and Nokia announced a worldwide strategic alliance aimed at integrating their e-mail, instant messaging and maps and navigation services on both PC and mobile devices. Select, co-branded service offerings are expected to become available from the second half of 2010, with global availability expected in 2011.

Under the deal, Nokia will be the exclusive, global provider of Yahoo!'s maps and navigation services, integrating Ovi Maps across Yahoo! properties, branded as "powered by Ovi." Yahoo! will become the exclusive, global provider of Nokia's Ovi Mail and Ovi Chat services branded as "Ovi Mail / Ovi Chat powered by Yahoo!". In addition, the companies will establish ID federation between their services, beginning by making it easy for people to use their Ovi user IDs across select Yahoo! properties to more easily access online content and services.

Some notable statistics:

  • Nokia shipped 432M mobile devices during 2009,that's 14 devices every second and 68M were smartphones

  • Every day, 1.2B people use a Nokia device

  • Yahoo! has 586M+ unique visitors globally, reaching 48% of the online population

Verizon Tunes its 40 Gbps Optical Wave Service for Wholesale Customers

Verizon Global Wholesale is rolling out a number of enhancements for its Optical Wave Service, including new 40 Gbps on OC768c Point-to-Point Link capabilities, 10 Gbps Channelized Wave with Muxing and a versatile interconnection offer.

Verizon's Optical Wavelength Service provides a fully managed, point-to-point circuit over a dedicated wavelength that runs across its ROADM-based shared network infrastructure. The wholesale service enables other carriers to directly monitor network performance and alarms.

Verizon's Optical Wave Service is now supporting 40 Gbps point-to-point transport. This new 40 Gbps capacity interfaced as an OC768c link, offering four times the capacity that was previously available.

The second new capability gives carriers the option of a 10G channelized (or multiplexed) wave service back to a point of presence. This allows them to aggregate lower speed services at a Verizon switching center location onto the 10G channelized wave service. In addition, customers can also deliver Optical Wave Service from a customer premises into a collocation space.

A third key enhancement allows the Optical Wave Service to interconnect with Verizon's SONET ring services (for example, IntelliLight Optical Transport Service and Integrated Optical Service). The enhancement enables ring customers to further embed and expand their network capabilities into a region with the simple provisioning of OWS circuits that run off of the ring at Verizon switching centers, avoiding the more costly connection process, which requires adding nodes to a ring. With provisioning, the capacity of the metro rings can be expanded less expensively and traffic fed onto the rings more economically, dropping the per-bit cost of data services.

"Our goal in creating new Optical Wave Service enhancements is to expand our fiber-based transport services, using the power of our metropolitan networks and the reconfigurable optical add drop multiplexers (ROADM) that power them so that our point-to-point wavelength services can deliver extremely high-quality and very cost-effective transport," said Matthew Duckworth, director of product marketing for Verizon Global Wholesale. "This is just the beginning of our efforts to continue to meet our wholesale customers' needs for bandwidth and reliable transport services that will help them succeed in the marketplace."

IBM Agrees to Acquire Sterling Commerce from AT&T for $1.4 Billion

IBM will acquire Sterling Commerce from AT&T for approximately $1.4 billion in cash.

Sterling Commerce, which is based near Columbus, Ohio, provides solutions for B2B integration, community management, secure file transfers, selling, order management, and logistics management. The company says 80 percent of the FORTUNE 500 use its solutions for business process integration, secure file transfers, multi-channel selling, supply chain fulfillment, and payment management, and that it enables more than 1 billion business interactions a year.

IBM sees these interactions growing dramatically due to the proliferation of electronic business transactions, from banks exchanging transaction data and manufacturers sourcing raw materials electronically, to retailers automating stock replenishment and managing orders online. Such intelligent transactions, and the software that supports them, help deliver the agility businesses need to be successful. This complements IBM's middleware portfolio.

"Businesses today are operating in a highly competitive global environment in which lines between actions taking place within and outside an organization's four walls are blurring," said Craig Hayman, general manager, WebSphere, IBM. "This acquisition will give IBM new tools to help clients build dynamic business networks that connect partners, suppliers and clients and deliver a consistent customer experience across channels. In addition, the fact that much of this can be done in the cloud will make it compelling to large numbers of our customers."

FCC Opens 25 MHz OF Spectrum for Mobile Broadband

The FCC adopted rules that will make available 25 megahertz of spectrum for mobile broadband service in much of the United States.

Specifically, the newly adopted Order amends the Wireless Communications Service (WCS) rules to immediately make 25 megahertz of spectrum available for mobile broadband services. The existing WCS rules constrain operations to fixed services, but the Commission found today that those rules can be revised to allow mobile broadband services without risking harmful interference to neighboring operations.

The FCC also adopted enhanced build-out requirements for WCS licensees, to ensure that the promise of mobile broadband is realized. These requirements are designed to spur investment that will promote the deployment of innovative mobile broadband services across the country.

Together, the Orders establish a regulatory framework for the co-existence of WCS and SDARS licensees in the 2.3 GHz frequency band in the following manner:

  • Mobile and portable broadband devices: Mobile and portable station power levels are permitted up to 250 mW average equivalent isotropically radiated power (EIRP) per 5 megahertz in WCS Blocks A and B and in the portions of WCS Blocks C and D that are separated by 2.5 megahertz from the SDARS band edges; duty cycle limitations and automatic transmit power control (ATPC) will apply; out of-band emissions (OOBE) requirements on WCS mobile and portable devices are also relaxed.

  • WCS base and fixed stations: Base and fixed stations in WCS Blocks A and B are permitted to operate with up to 2 kW average EIRP per 5 megahertz but stations in the C and D blocks remain limited to the 2 kW peak EIRP level currently specified in the Rules; WCS base and fixed stations' OOBE are also relaxed; a notification process with SDARS and coordination process with aeronautical mobile telemetry (AMT) users are also established.

  • Performance requirements for WCS licensees: For mobile and point-to-multipoint services, WCS licensees must serve 40 percent of a license area's population within 42 months, and 75 percent within 72 months. For fixed point-to-point services, WCS licensees must construct and operate 15 point-to-point links per million persons in a license area within 42 months, and 30 links within 72 months, together with a minimum payload capacity to ensure that the spectrum is used intensively. Licensees will not be required to satisfy submarket construction requirements.

  • WCS Coordination with Flight Testing Service. In those license areas where WCS licensees must coordinate with aeronautical mobile telemetry receive sites to serve a significant percentage of a market's total population, alternative requirements apply for mobile and point-to-multipoint services. Specifically, affected licensees must serve 25 (rather than 40) percent of the population within 42 months, and 50 (rather than 75) percent within 72 months.

  • SDARS terrestrial repeaters: Permanent rules are established for the operation of SDARS terrestrial repeaters. Repeaters operating up to 12 kW average EIRP will be authorized under a blanket licensing regime. The Commission also denies petitions for reconsideration of the 1997 SDARS Order filed by the Consumer Electronics Manufacturing Association (CEMA) and the Cellular Phone Taskforce.

The National Broadband Plan recommends that the Commission make 500 megahertz of spectrum available for broadband use in the next 10 years, including 300 megahertz for broadband use in the next five years.

FCC Approves Verizon-Frontier Deal

The FCC approved the transfer of 4.8 million lines in primarily rural and smaller-city areas to Frontier Communications from Verizon Communications.

The FCC believes the transaction will help advance the goals of the National Broadband Plan by bringing broadband to millions of consumers, small businesses, and anchor institutions in 14 states across the West, Midwest, and South.

To gain the approval, Frontier has committed to deploy broadband with actual speeds of at least 3 Mbps downstream to at least 85 percent of transferred lines by the end of 2013, and actual speeds of at least 4 Mbps downstream to at least 85 percent of the transferred lines by the end of 2015, with all new broadband deployment offering actual
speeds of at least 1 Mbps upstream.

In addition Frontier will launch an anchor institution initiative to deploy fiber to libraries, hospitals, and government buildings, particularly in unserved and underserved communities.

Fujitsu and University of Tokyo Develop 25 Gbps Quantum Dot Laser

Fujitsu Laboratories and the University of Tokyo have developed the first quantum dot laser capable of 25 Gbps transmission. Researchers believe the technology can be scaled to 100 Gbps and above.

Quantum dot lasers are semiconductor lasers which employ quantum dots - nanometer-sized semiconductor particles as an active material for lasing. The researchers cite several advantages over other types of semiconductor lasers, such as being less sensitive to temperature fluctuations, while offering tremendous advances over previous semiconductor lasers in terms of lower power consumption, greater transmission distances, and faster speeds.

Quantum well lasers, which have conventionally been used as optical sources for data communications, have a problem of dramatic increases in power consumption attributable to increased driving current when temperatures rise. The quantum dot laser developed by Fujitsu Laboratories and the University of Tokyo uses 3-dimensional (3D) semiconductor nanostructures to produce quantum effects, thus giving it excellent characteristics, including stable operation over a range of temperatures and low power consumption. However, the quantum dot laser had been limited to handling data transfer speeds up to 10 Gbps.

In order to increase the speed of quantum dot lasers, it was necessary to increase the laser's optical gain, which in turn required an increase in the number of underlying quantum dots. New quantum dot fabrication technology was developed and applied. Layers of quantum dots with a higher density than conventionally employed were then stacked, thereby doubling the laser's operation speed and enabling a significant improvement over previous technologies. The result was a quantum dot laser capable of high-speed operations at 25 Gbps.

Fujitsu and Fujitsu Laboratories have developed this technology in an industrial-academic collaboration with Professor Yasuhiko Arakawa's laboratory of the University of Tokyo. Part of this research belongs to a project contracted to the Photonics Electronics Technology Research Association (PETRA) by the New Energy and Industrial Technology Development Organization (NEDO), while part of the research was carried out under Japan's Ministry of Education, Culture, Sports, Science and Technology's Special Coordination Funds for Promoting Science and Technology.
