Transect China in Half the Time Aboard the World's Longest High-Speed Rail Line

This story will display in ...

Transect China in Half the Time Aboard the World's Longest High-Speed Rail LineHigh speed rail may be a quixotic public works project here in California but for China, it's a cornerstone of the country's transportation infrastructure. Yesterday, Chinese officials expanded that infrastructure by inaugurating the longest such rail line on Earth and announced plans for seven more.

While not nearly as fast as the Tokyo-Nagoya mag-lev line Japan is working on, the high speed line running from, Beijing, the capital city of the People's Republic of China to Guangzhou, a provincial capital 1,428 miles (2,298 kilometers) to the South, is nearly five times as long. What's more, the line's trains reach speeds of 186 MPH (300 KPH) which shaves an astounding 12 hours off the trip. What was once a 20 hour-plus trek, now takes only eight. More than 150 pairs of trains will serve the line every day—darting from one capital city to the other with stops at other provincial capitals—Shijiazhuang, Wuhan and Changsha—along the way.

This is just one of eight new HSR lines China hopes to construct by 2020—four North-South and four East-West—to help ferry goods and people across the country's vast territories without having to rely on airlines or freeways. Instead, the Ministry of Railways (MOR) has upgraded conventional lines to accommodate high speed trains, built designated passenger lines, and even dabbled in mag-lev technology. In all, China operates the longest HSR network in the world, maintaining more than 5,800 miles (9,300 km) of rail. The MOR is working to more than double that figure to 11,184 miles (18,000 km) by 2015, according to the Xinhua News Agency, as part of the country's modernization efforts.

Gigabit Squared heading high-speed fiber and wireless internet initiative in Seattle

CITY OF SEATTLE, UNIVERSITY OF WASHINGTON, AND GIGABIT SQUARED ANNOUNCE PLAN TO DEVELOP ULTRA-FAST BROADBAND NETWORK

Plan begins with demonstration fiber project in 12 Seattle neighborhoods

SEATTLE (December 13, 2012) – Today Seattle Mayor Mike McGinn announced that the City of Seattle has reached an agreement with broadband developer Gigabit Squared to develop and operate an ultra high-speed fiber-to-the-home/fiber-to-the-business broadband network. The plan will begin with a demonstration fiber project in twelve Seattle neighborhoods and includes wireless methods to deploy services more quickly to other areas in the city. The initiative, leveraging the City of Seattle's excess fiber capacity, the expertise of Gigabit Squared, and the community leadership of The University of Washington, aims to stimulate business opportunities, spur advancements in health care, education, and public safety, and enhance quality of life for the residents and businesses of Seattle.

"This is a very promising proposal that can help bring 21st century infrastructure to Seattle," said McGinn. "I've heard from residents and businesses that Seattle needs better broadband service, and this agreement lays the groundwork for building that network. I'm excited to work with the University of Washington and Gigabit Squared to provide new Internet service choices."

The City, the University and Gigabit Squared have signed a Memorandum of Understanding and a Letter of Intent that allows Gigabit Squared to begin raising the capital needed to conduct engineering work and to build out the demonstration fiber network. The project is the second city project announced by Gigabit Squared as part of its multi-million dollar Gigabit Neighborhood Gateway Program. Gigabit Squared will collaborate with the City of Seattle and the University of Washington to initiate a process for sharing information and soliciting input on the project from members of the affected communities.

"The UW, the City of Seattle and Gigabit Squared are working together to make Seattle the most wired and connected city in the nation and to continue its role as a major leader in the innovation economy of the 21stcentury," said University of Washington President Michael Young. "This new level of high-speed connectivity will provide essential infrastructure to help us address some of our biggest problems in the areas of climate, the environment, education, energy, and transportation. It's definitely a game-changer, and we are delighted to be one of the driving forces in making this a reality."

The network, called Gigabit Seattle (www.gigabitseattle.com) includes three pieces: Fiber directly to the home and business in twelve demonstration neighborhoods, dedicated gigabit broadband wireless connections to multifamily housing and offices across Seattle, and next generation mobile wireless internet.

1) Fiber to the home and business: Gigabit Seattle plans to build out a fiber-to-the-home/fiber-to-the-business (FTTH/FTTB) network to more than 50,000 households and businesses in 12 demonstration neighborhoods, connected together with the excess capacity that Gigabit Seattle will lease from the City's own fiber network. Gigabit Seattle's technology intends to offer gigabit speeds that are up to 1,000 times faster than the typical high-speed connection.

The initial 12 neighborhoods include: Area 1: the University of Washington's West Campus District, Area 2: South Lake Union, Area 3: First Hill/Capitol Hill/Central Area, Area 4: the University of Washington's Metropolitan Tract in downtown Seattle, Area 5: the University of Washington's Family Housing at Sand Point, Area 6: Northgate, Area 7: Volunteer Park Area, Area 8: Beacon Hill and SODO Light Rail Station and Areas 9-12: Mount Baker, Columbia City, Othello, and Rainier Beach.

2) Dedicated gigabit to multifamily housing and offices: To provide initial coverage beyond the 12 demonstration neighborhoods, Gigabit Seattle intends to build a dedicated gigabit broadband wireless umbrella to cover Seattle providing point-to-point radio access up to one gigabit per second. This will be achieved by placing fiber transmitters on top of 38 buildings across Seattle. These transmitters can beam fiber internet to multifamily housing and offices across Seattle, even those outside the twelve demonstration neighborhoods, as long as they are in a line of sight. Internet service would be delivered to individual units within a building through existing wiring. This wireless coverage can provide network and Internet services to customers that do not have immediate access to fiber in the city.

3) Next generation mobile wireless internet: Gigabit Seattle will provide next generation wireless cloud services in its 12 neighborhoods to provide customers with mobile access.

The fiber network, the gigabit dedicated wireless connections, and wireless cloud services neighborhoods will together provide broadband wired and wireless network and Internet services, giving Seattle customers new choices.

"Seattle and its spirit of entrepreneurship, community advancement, innovation and invention make it the ideal City for this exciting initiative," said Mark Ansboury, president of Gigabit Squared. "Bringing the City of Seattle, the University of Washington, individual neighborhoods, as well as Gigabit Squared and our investors together, we're able to do what none of us could do individually – build a platform for economic development and business creation."

This is the first demonstration project of Gigabit Squared's Gigabit Neighborhood Gateway Program (GNGP), which will bring other projects like this to promote gigabit network innovation in six selected university communities across the country. The $200 million broadband program was developed in partnership with The University Community Next Generation Innovation Project (Gig.U).

"This exciting public-private partnership serves as an example to communities all over the world of how universities and their local stakeholders can collaborate to drive economic opportunities by putting private investment to work alongside public capital," said Blair Levin, Executive Director of Gig.U. "We're thrilled to see our Gig.U member, University of Washington, at the center of this innovative initiative to help Seattle communities benefit from the advanced applications and services accelerating the meaningful use of this gigabit speed network. Congratulations to all involved in the Seattle Broadband Initiative in developing this world-class fiber network that will support not only today's needs, but foster innovation and serve the research and community development needs of tomorrow."

IBM to showcase high-speed silicon nanophotonic technology at IEEE

A new IBM technology that has been in development for more than 10 years will be showcased this week at the IEEE International Electron Devices Meeting in San Francisco. It’s called silicon nanophotonics and according to the technology company, it could extend the life of networking equipment by a significant margin.

The technology uses pulses of light to transmit large amounts of data at very high speeds - up to 25Gbps per channel. Existing optical networks use individual silicon and photonic components but this new method would put all of that functionality onto a single chip.

Solomon Assefa, a nanophotonics scientist for IBM Research, says silicon allows for very dense integration. Instead of having just a single lane, this technology could allow for 50 different lanes, exponentially increasing bandwidth in the process.

Big Blue says the technology will ultimately replace interconnects currently used in data centers, servers and supercomputers. Experts are concerned because computers are becoming faster than the methods used to help them communicate with each other, introducing an unnecessary performance bottleneck that needs a solution before hardware could be pushed further.

This isn’t the first we have heard of silicon nanophotonics as IBM published a proof of concept in 2010. Since then, however, they have figured out how to build the components using current generation fabrication processes (90 nanometer, in this instance) while still maintaining the same level of performance and reliability that was originally conceived. They also claim that the technology can become a reality without incurring excessive cost.
