'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 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."
