NTT employs Orbital Angular Momentum multiplexing for 100G wireless

NTT successfully demonstrated the first use of Orbital Angular Momentum (OAM) multiplexing to achieve 100 Gbps wireless transmission.

The laboratory tests combined OAM multiplexing with Multiple-Input Multiple-Output (MIMO) technology and carried the signals a distance of 10m.

NTT said a key feature of OAM is that electromagnetic waves can be superposed and separated because phase rotation occurs on the vertical plane in the propagation direction.  An electromagnetic wave with phase rotation cannot be received without a receiver having the same number of phase rotations at the time of transmission. NTT developed a transceiver operating in the 28 GHz band capable of OAM transmission. NTT also developed signal processing technology capable of handling 11 data signals simultaneously each at a bit rate of 7.2 to 10.8 Gbps, thereby achieving large-capacity wireless transmission at a total bit rate of 100 Gbps.

NTT believes the technology holds promise for achieving large-capacity wireless transmission at a level about 100 times that of LTE and Wi-Fi and about 5 times that of 5G.

Deutsche Telekom pursues “billions for millions” broadband strategy

Deutsche Telekom invested 5.4 billion euros on networks and new data centers in Germany in the last year, he said.

Speaking at Deutsche Telekom's shareholders' meeting in Bonn, CEO Tim Höttges said the company is pursuing a strategy of “billions for millions,” seeking to ensure that broadband coverage is built out as quickly and as comprehensively as possible. The targets for the next stage of Deutsche Telekom's broadband strategy are to provide 26 million households with up to 100 Mbps, and 15 million households with as much as 250 Mbps, by the end of the year.

Deutsche Telekom holds a 40 percent market share in the broadband market in Germany.

Höttges also called for increased competition in Germany, saying that other companies must also invest in new networks, instead of simply criticizing or “staying cozy in regulated markets.” Höttges said that there should be no more regulation for “new fiber-optic lines,” in order to achieve the goal of nationwide access to gigabit speeds faster.” We are pleased to have competition, at any rate, because if it is fair, then it is good for the customer,” said Höttges.

In 2017, Deutsche Telekom's revenue increased by 2.5 percent year-on-year to 74.9 billion euros, with adjusted EBITDA rising by 3.8 percent to 22.2 billion euros. Free cash flow was up 11.3 percent to 5.5 billion euros.

Regarding the planned merger with Sprint, Höttges said the deal would create better networks, new jobs, increased growth, and stronger competition in the United States. “I personally have spent seven years working to make this merger happen. There have been many ups and downs, but there is no opportunity without risks – risks that must be taken if we are to open up new horizons. I am convinced that this business combination is the best thing for the U.S. market and for Deutsche Telekom – and that goes for the long term,” said Tim Höttges.

Deutsche Telekom will further discuss its medium-term planning at its Capital Markets Day on May 24/25.

Tachyum announces its Universal Processor Platform

Tachyum, a start-up based in San Jose, California with offices in Slovakia, unveiled its new processor family – codenamed “Prodigy” – that combines the advantages of CPUs with GP-GPUs, and specialized AI chips in a single universal processor platform. The company says its processor architecture attains ten times the processing power per watt compared to conventional designs.

A key innovation of the design is the ability to connect very fast transistor with very slow wires, but technical details on the device physics have not yet been disclosed.

The universal processor promises programming ease comparable to a CPU with performance and efficiency comparable to GP-GPU. It is designed to handle hyperscale workloads, AI, HPC, and other demanding applications

Tachyum claims its Prodigy universal processor will enable a super-computational system for real-time full capacity human brain neural network simulation by 2020. One target application would be the real-time Human Brain Project, where there’s a need for more than 1019 Flops (10,000,000,000,000,000,000 floating-point operations per second - 10 exaflop).

“Rather than build separate infrastructures for AI, HPC and conventional compute, the Prodigy chip will deliver all within one unified simplified environment, so for example AI or HPC algorithms can run while a machine is otherwise idle or underutilized,” said Tachyum CEO Dr. Radoslav ‘Rado’ Danilak. “Instead of supercomputers with a price tag in the hundreds of millions, Tachyum will make it possible to empower hyperscale datacenters to produce more work in a radically more efficient and powerful format, at a lower cost.”

“Despite efficiency gains from virtualization, cloud computing, and parallelism, there are still critical problems with datacenter resource utilization particularly at a size and scale of hundreds of thousands of servers,” said Christos Kozyrakis, professor of electrical engineering and computer science at Stanford, who leads the university’s Multiscale Architecture & Systems Team (MAST), a research group for cloud computing, energy-efficient hardware, and operating systems. “Tachyum’s breakthrough processor architecture will deliver unprecedented performance and productivity.” Kozyrakis is a corporate advisor to Tachyum.

Verizon deploys LTE over CBRS spectrum

Verizon announced 4G LTE over CBRS spectrum (Citizens Broadband Radio Service) using its live commercial network in Florida.

The deployment uses a combination of Verizon licensed AWS and 700 MHz spectrum aggregated with 50 MHz of CBRS band 48 spectrum.  Verizon said it has achieved peak speeds of 790 Mbps using LTE Advanced features including multiple antennas, 256 QAM, and carrier aggregation across the shared and licensed spectrum.  The deployments in Florida involved outdoor and in-building systems.

Ericsson provided Ericsson Radio DOT system for indoor and Radio 2208 for outdoor, Qualcomm provided its Snapdragon TM 845 mobile test device with X20 LTE for access to CBRS on mobile devices, and Federated Wireless provided the prioritization through their Spectrum Controller, a Spectrum Access System (SAS) that dynamically allocates channels within the FCC’s spectrum sharing framework for this band.  Ericsson also provided the domain proxy to enable the radios to communicate with the Federated Wireless Spectrum Controller.

Commercial devices that can access the CBRS spectrum are expected in 2018.

Verizon said this real-world deployment marks the beginning of public access to the 150 MHz bandwidth of 3.5 GHz shared spectrum which until now has been used by the federal government for radar systems.

“As more people use more wireless devices to do more things in more places, building a network to stay ahead of customer demand is crucial,” said Mike Haberman, VP Network Engineering for Verizon.  “This shared spectrum resource is a critical component of our strategy to add capacity to our network.”

“We have been aggressively working over the past several years on deploying LTE Advanced features.  We’ve fully deployed carrier aggregation in our licensed spectrum across our network in over 2,000 markets, and have 4X4 MIMO and 256 QAM deployed in over 810 markets nationwide for our customers,” said Haberman.  “Combining those features with this shared spectrum band will provide more capacity, higher peak speeds and faster throughput when accessing the network for our customers who have come to expect the latest technology and highest reliability from Verizon.”

U.S. Senate votes to rescind FCC order ending Net Neutrality

The FCC voted 52-to-47  in favor of a bill that reverses the FCC's recent order ending Net Neutrality.

The bill now goes to the U.S. House of Representatives for consideration.


FCC votes 3-2 to end Net Neutrality rules

The FCC voted 3-2 along partisan lines to adopt the "Restoring Internet Freedom Order" proposed by FCC Chairman Ajit Pai to rollback Obama-era Net Neutrality rules. Voting in favor of the order were Republicans Ajit Pai, who argued that measure will usher in a new era of investment for Internet infrastructure. Also voting in favor were Republicans Michael O'Rielly and Brendan Carr. Voting against the measure were Democrats Mignon Clyburn and Jessica Rosenworcel.

FCC Chairman said that by returning to the classification of Internet services as an “information service”— removing the current Title II regulatory regime that gives the FCC say over the delivery of Internet content — the new order returns the industry to the status quo prior to 2015.

The vote proceeded despite an urgent request from the Attorney Generals of 18 states urging a delay to the vote due to a criminal investigation into possible fraudulent manipulation of the FCC's public comment process for this issue.  In a public letterto FCC Commissioners, the Attorney Generals said their ongoing review of the public comments process has revealed a large number of fake comment submissions using the names and identities of real people. The initial assessment is that there were over 1 million fake comments indicating a deliberate effort to skew the public comment process on an issue of national importance. The Attorney Generals are also requesting the help of the FCC in their investigation of "massive identity theft."

President Trump Picks Pai for FCC Chairman



President Donald J. Trump designated Ajit Pai as his choice to be Chair of the FCC. Ajit Varadaraj Pai was nominated for FCC Commissioner by President Obama in 2011. Pai took over the seat abandoned by Meredith Baker who left the FCC to take a job as a lobbyist for Comcast. Pai was previously a Partner in the Litigation Department of Jenner & Block LLP. Previously, Pai worked in the Office of the General Counsel at the Federal Communications...







FCC Votes 3-2 to Adopt Open Internet Rules

The Federal Communications Commission voted 3-2 to adopt a new set of Open Internet rules proposed by Commissioner Wheeler and backed by the Obama Administration. All of the new rules, which are based on the FCC's authority under Title II of the Communications Act of 1934, would apply to fixed and mobile broadband alike, while leaving room for reasonable network management and its specific application to mobile and unlicensed WiFi networks.

Here are the key provisions and rules of the Open Internet Order as outlined by the FCC:

Bright Line Rules:  The first three rules ban practices that are known to harm the Open Internet.

  • No Blocking: broadband providers may not block access to legal content, applications, services, or non-harmful devices.
  • No Throttling: broadband providers may not impair or degrade lawful Internet traffic on the basis of content, applications, services, or non-harmful devices.
  • No Paid Prioritization: broadband providers may not favor some lawful Internet traffic over other lawful traffic in exchange for consideration of any kind—in other words, no “fast lanes.”   This rule also bans ISPs from prioritizing content and services of their affiliates. It also prohibits practices that target specific applications or classes of applications.

Verizon designates AWS as its Preferred Public Cloud Provider

Verizon Communications has designated Amazon Web Services (AWS) as its preferred public cloud provider as part of a corporate-wide initiative to increase agility and reduce costs through the use of cloud computing.

Verizon is migrating over 1,000 business-critical applications and database backend systems to AWS, several of which also include the migration of production databases to Amazon Aurora—AWS’s relational database engine. Verizon is also building AWS-specific training facilities, called “dojos,” where its employees can quickly ramp up on AWS technologies and learn how to innovate with speed and at scale.

The companies noted that Verizon first started working with AWS in 2015. This latest wave of migrations to AWS accelerates Verizon's digital transformation.

"We are making the public cloud a core part of our digital transformation, upgrading our database management approach to replace our proprietary solutions with Amazon Aurora," said Mahmoud El-Assir, Senior Vice President of Global Technology Services at Verizon. “The agility we’ve gained by moving to the world’s leading public cloud has helped us better serve our customers. Working with AWS complements our focus on efficiency, speed, and innovation within our engineering culture, and has enabled us to quickly deliver the best, most efficient customer experiences."

“We look forward to continuing our work with Verizon as their preferred public cloud provider, helping them to continually transform their business and innovate on behalf of their customers. The combination of Verizon’s team of builders with AWS’s extensive portfolio of cloud services and expertise means that Verizon’s options for delighting their customers is virtually unlimited,” stated Mike Clayville, Vice President, Worldwide Commercial Sales at AWS.

NEC and Google test subsea modulation using probabilistic shaping

NEC and Google have tested probabilistic shaping techniques to adjust the modulation of optical transmission across the 11,000-km FASTER subsea cable linking the U.S. and Japan.

The companies have demonstrated that the FASTER open subsea cable can be upgraded to a spectral efficiency of 6 bits per second per hertz (b/s/Hz) in an 11,000km segment -- representing a capacity of more than 26 Tbps in the C-band, which is over 2.5X the capacity originally planned for the cable, for no additional wet plant capital expenditure. The achievement represents a spectral efficiency-distance product record of 66,102 b/s/Hz.

The field trial was performed with live traffic on neighboring channels.

The companies said their test used near-Shannon probabilistic-shaping at a modulation of 64QAM, and for the first time on a live cable, artificial intelligence (AI) was used to analyze data for the purpose of nonlinearity compensation (NLC). NEC developed an NLC algorithm based on data-driven deep neural networks (DNN) to accurately and efficiently estimate the signal nonlinearity.

"Other approaches to NLC have attempted to solve the nonlinear Schrodinger equation, which requires the use of very complex algorithms," said NEC's Mr. Toru Kawauchi, General Manager, Submarine Network Division. "This approach sets aside those deterministic models of nonlinear propagation, in favor of a low-complexity black-box model of the fiber, generated by machine learning algorithms. The results demonstrate both an improvement in transmission performance and a reduction in implementation complexity. Furthermore, since the black-box model is built up from live transmission data, it does not require advance knowledge of the cable parameters. This allows the model to be used on any cable without prior modeling or characterization, which shows the potential application of AI technology to open subsea cable systems, on which terminal equipment from multiple vendors may be readily installed."

Transpacific FASTER Cable Enters Service with 60 Tbps Capacity

The world's highest capacity undersea cable system has entered commercial service -- six fiber pairs capable of delivering 60 Terabits per second (Tbps) of bandwidth across the Pacific.

FASTER is a 9,000km trans-Pacific cable connecting Oregon and two landing sites in Japan (Chiba and Mie prefectures). The system has extended connections to major hubs on the West Coast of the U.S. covering Los Angeles, the San Francisco Bay Area, Portland and Seattle. The design features extremely low-loss fiber, without a dispersion compensation section, and the latest digital signal processing technology.

Google will have sole access to a dedicated fiber pair. This enables Google to carry 10 Tbps of traffic (100 wavelengths at 100 Gbps). In addition to greater capacity, the FASTER Cable System brings much needed diversity to East Asia, writes Alan Chin-Lun Cheung, Google Submarine Networking Infrastructure.

Construction of the system was announced in August 2014 by the FASTER consortium, consisting of China Mobile International, China Telecom Global, Global Transit, Google, KDDI and Singtel.
