    Exclamation Sprint's Network Vision initiative

    What is Sprint's 'Network Vision' ?

    http://newsroom.sprint.com/press_kit...presskit_id=19

    Network Vision, originally announced in December 2010, is Sprint’s plan to consolidate multiple network technologies into one seamless network with the goal of increasing efficiency and enhancing network coverage, call quality and data speeds for customers across the United States.

    On Oct. 7, 2011, Sprint announced its plans to accelerate deployment of Network Vision and its plans to roll out 4G LTE on its 1.9 GHz licensed spectrum. Sprint expects the rapid deployment to reach 250 million people by the end of 2013.


    Dan Hesse, Sprint CEO
    “Our progress deploying Network Vision enables Sprint to extend and evolve our 4G leadership and to improve the experience for 3G customers. Our next-generation network and cutting-edge device lineup, combined with the industry’s best pricing plans, give Sprint customers the best experience in wireless.”


    Current vs. New cell site

    Today, Sprint uses separate equipment to deploy services on 800 MHz and 1.9 GHz spectrum. Through Network Vision Sprint will install new network equipment and software that brings together multiple spectrum bands, or airwaves, on a single, multimode base station. The new equipment makes it easy to accommodate additional spectrum bands.





    With Network Vision, Sprint will make substantial changes to the cell sites that power its wireless network. The top image shows Sprint’s existing base stations, which require single, refrigerator-sized cabinets for each technology. Large black coaxial cables must run from each cabinet to the top of the cell tower, which has an inherent loss of signal. The Network Vision multi-mode base station will require less space. Other advantages will include the ability for Sprint to use spectrum bands on multiple technologies, replacing coaxial cables with fiber that is not affected by signal loss and improved remote radio heads that replace existing less efficient radios.


    Multi-mode technology


    The implementation of multimode technology throughout the Sprint network will:
    • Enhance service
    • Create network flexibility
    • Reduce operating costs
    • Improve environmental sustainability

    · Berge Ayvazian, Senior Consultant, Heavy Reading
    “This is a very bold move. Sprint was first with an all-digital wireless network; the first to upgrade to EVDO; and more recently, the first to broadly offer 4G services. Sprint is once again first to deploy a common converged mobile network that will strengthen its 3G services; enhance its 4G technology options; and continue delivering the industry’s leading push-to-talk offering.” -- December, 2010

    7/30/2013
    Network Vision Progress: Strong progress on Network Vision deployment with more than 20,000 sites currently on air -- up 50 percent from last quarter. The number of sites that are either ready for construction, already underway or completed has grown to more than 30,000.

    Roll-out of LTE on 1.9 GHz spectrum: Sprint will extend its 4G leadership position in the U.S. by adding LTE technology to enhance its current 4G offerings, with plans to launch LTE on its existing 1.9 GHz spectrum by mid-year of 2012. Sprint expects its 4G coverage footprint to cover 200 million people by the end of 2013.

    Sprint Direct Connect: On October 2, 2011 Sprint launched Sprint Direct Connect, the next generation of push-to-talk service with broadband data capabilities. Operating on the CDMA network, we expect Sprint Direct Connect to give customers 3x greater coverage—from 900,000 square miles to approximately 2.7 million - a broader lineup of devices including smartphones, and all the benefits associated with broadband capabilities.

    3G Network Improvement: Sprint expects a significant improvement in customers’ 3G network experience, including expanded coverage, improved network reliability, better voice quality, and faster 3G data speeds. Based on forecasts of data demand, Sprint is confident its 3G network will meet customers’ growing data demands.

    Financial benefit to Sprint

    · Sprint expects the Network Vision plan to bring financial benefit to the company.

    · This is to come from reducing operating costs and also by avoiding future expenses as wireless data traffic continues to grow.

    · The total estimated incremental cost of the Network Vision program over the deployment period is between $4 billion and $5 billion.

    · Sprint estimates the total net financial benefit over a seven-year period will be between $10 billion and $11 billion.

    · Cost savings are expected to come from capital efficiencies, reducing energy costs, lowering roaming expenses, backhaul savings and the eventual reduction in the total number of cell sites.



    EV-DO Advanced, while offering operators a way to improve network performance via a software upgrade, doesn't address peak download speeds. It does, however, improve overall network capacity and latency through techniques such as load balancing, adaptive frequency reuse and single-carrier multilink. Moreover, the upgrade is compatible with existing Rev. A devices.

    1X Advanced builds on 1X technology and adds techniques such as BTS interference cancellation, radio link enhancements and others to provide boosts to performance including up to a 4x increase in voice capacity and up to a 70% increase in coverage.



    'Sprint Deploying 2.5GHz LTE Nationwide'



    "Now that we own 100 percent of Clearwire, with the help of SoftBank, we said, how do we take full advantage of the 2.5 GHz spectrum?" Euteneuer said. "The best way to do that is to have it fully integrated with the rest of your spectrum capabilities. And to do that you really need to put it on every tower."

    The Sprint CFO said because of the weaker propagation characteristics of 2.5 GHz, Sprint will deploy small cells and other sites beyond the 38,000 Network Vision sites the company has mapped out. He said it is unclear at this point if the nationwide deployment of Clearwire's spectrum will be finished by the end of 2014. Clearwire commands around 160 MHz of spectrum in the top 100 markets.

    Looking ahead though, Elfman said the 2.5 GHz expansion will proceed at a brisk clip. "It will not be fully built up, but it will be quite a bit easier than the current Network Vision plan because we will already have backhaul," Elfman said of the 2.5 GHz expansion, according to a Seeking Alpha transcript. "We will already have done most of the leasing and it will be more of an overlay effect the way you're seeing our competitors do overlay LTE network. So it will move much faster than the current Network Vision plan."

    Sprint Picks Ciena for 400G

    http://www.lightreading.com/document.asp?doc_id=221923&

    Sprint plans to upgrade its optical backbone with 400Gbit/s coherent wavelengths running on Ciena Corp. gear, the vendor is announcing Wednesday.

    The new backbone will run on Ciena's 6500 Packet-Optical Platform exclusively, Ciena says. The 400Gbit/s part won't come right away, as the interfaces aren't shipping yet. Sprint and Ciena are planning for field trials to run in early 2013.

    Sprint was already using Ciena's optical gear in general. The upgraded backbone is part of Sprint's overall Network Vision plan, which includes Alcatel-Lucent, Ericsson AB and Samsung Corp. in other capacities.

    Ciena has already said that BT Group plc will be a 400Gbit/s customer as well.

    Why this matters

    It's further evidence that 400Gbit/s will be important as a stopgap while the industry waits for 1Tbit/s transmission to be developed. Bandwidth demand, it seems, really is that urgent in spots.

    AlcaLu implied as much in May, claiming 20 customers are ready to deploy its 400Gbit/s interfaces when they're ready at the end of the year.

    'Sprint enables 100G Ethernet wavelength services, sets path for 400G'


    Sprint (NYSE: S) continues to make progress with its own 100G optical path by completing two key trials of the technology on its wireline network.

    Working with its optical systems partner Ciena (Nasdaq: CIEN), the service provider deployed a 100G circuit over a 1,304-mile span in the United States and recently completed a live 400G trial.

    During its 100G circuit trial, which is now integrated into its network infrastructures and is in-service between Chicago and Fort Worth, Texas, it did not need to conduct regeneration between each point. Sprint said that being able to transmit at longer distance enables the service provider to reduce latency and increase reliability.

    The service provider said that the 100G technology it has deployed will enable it to achieve speeds up to 10X faster and, later, up to 40x faster without network upgrades. Its Ethernet Wave Services can provide 100G speeds now and 400G in the future.

    In its 400G trial in Silicon Valley, Sprint ran 400 Gbps channels alongside existing channels carrying live customer traffic. While it has not announced any specific date as to when it would need 400G, it said that it "foresees the opportunity to add a network equivalent of high-speed traffic lanes for customers with high-demand requirements."

    As previously reported, Sprint is upgrading its optical network backbone with Ciena's 6500 platform to support its Network Vision initiative.

    'Sprint reaches new milestones for network speed'

    Teaming with Ciena, Sprint demonstrates network readiness to support rapidly growing wireless and wireline data needs of customers

    OVERLAND PARK, Kan., and HANOVER, Md. — 08/15/2013

    Sprint (NYSE:S) and Ciena (NASDAQ: CIEN) have teamed to achieve two significant milestones in speed and capacity on Sprint's network:

    · Earlier this year, the companies trialed, and Sprint has since deployed, one of the longest 100 Gigabits-per-second (Gbps) circuits in the United States with a live transmission that required no signal regeneration over a distance of 2,100 km, or 1,304 miles.

    · Last month, the companies successfully completed a live 400Gbps trial on Sprint's network.

    The trials validate Sprint's leadership in deploying new network technologies designed to meet exponential growth in demand for data by Sprint business and consumer customers. This includes bandwidth-intensive cloud services and other applications like streaming HD video, telepresence and high-capacity data center connectivity.

    Until recently, the Sprint network offered wireline services at speeds of up to 10Gbps. The trials demonstrated the viability of using innovative technology to achieve speeds up to 10 times faster (and up to 40 times faster in the future), without requiring costly network upgrades to Sprint's robust fiber infrastructure. Sprint Ethernet Wave Services will support 100Gbps speeds now, and Sprint expects to leverage Ciena's coherent optical technology to support services operating at 400Gbps in the future.

    Key results from the two field trials:

    100Gbps: The 100Gbps circuit trialed earlier this year is now integrated into the Sprint optical network infrastructures and is in-serviced between Chicago and Fort Worth, Texas. The 100Gbps link uses Ciena WaveLogic 3 coherent optical processors on the 6500 Packet Optical Platform to enable Sprint to successfully transmit data at 100Gbps over the 2,100km (1,304-mile) circuit, with no regeneration of the signal at points in between. The longer distance between regeneration points provides reduced latency, hardware benefits and improved reliability, flexibility and performance for customers.

    400Gbps: This trial was performed in the Silicon Valley area using existing Sprint fiber infrastructure and Ciena's 6500 with WaveLogic 3 cards; this high-capacity link operated without error. This demonstrated the viability of using 400Gbps channels alongside existing channels carrying live customer traffic. As a result, Sprint foresees the opportunity to add a network equivalent of high-speed traffic lanes for customers with high-demand requirements.

    "Customers have expressed their hunger for higher speed networks to support their substantial data needs, which we project will only continue to grow exponentially," said Wayne Ward, vice president-Business and Product Development, Sprint. "The 400Gbps trial demonstrates our ability to offer higher speeds with our existing fiber, which means that our customers can feel assured that our network is future-proofed to meet their needs as they evolve. The delivery of 100Gbps and 400Gbps speeds will be critical as we launch our Ethernet Wave Services and support a growing wireless infrastructure."

    As announced in 2012, Sprint is upgrading its optical backbone network with Ciena's 6500 Packet-Optical Platform as part of its Network Vision initiative. The advanced network is expected to enable Sprint to enhance transport network scalability, cost and performance. By adding Ciena's coherent optical technology to the mix, Sprint can scale its core network initially to 40Gbps and 100Gbps, and later to 400Gbps and beyond, as network demands dictate.

    "Service providers are increasingly challenged to satisfy surging demand for bandwidth-hungry services and applications," said Francois Locoh-Donou, senior vice president-Global Products Group, Ciena. "Ciena's market-leading coherent technology offers the flexibility, programmability, scalability and cost-efficiency needed to meet these demands at 100Gbps speeds, 400Gbps speeds and beyond. These recent trials illustrate Sprint's ability to support high-speed data and significantly increase the traffic-carrying capacity of optical channels with no change to the underlying infrastructure – and that is a significant coup for any operator in this highly competitive market."
