Blue Danube intros 96-element, Multiband, Massive MIMO Antenna

Blue Danube Systems, a start-up based in Santa Clara, California, introduced its 96-element, second-generation 5G-ready Massive MIMO system.

Blue Danube's the BeamCraft 600 series supports simultaneous beamforming over multiple frequency bands and across multiple cellular standards, allowing operators to deliver increased capacity through a single compact system.

The company said its Massive MIMO can dynamically direct radio frequency (RF) beams where mobile traffic is high and without changes to existing cell sites or smartphones. The 96-element BeamCraft 600 supports up to two active mid bands using 16 software configurable beams, double the capacity of the company’s previous generation. An integrated passive low-band option is also available to further conserve antenna mount positions.  Blue Danube has deployed active solutions in 3 mid bands to date (AWS, PCS, DCS) and will trial the multi-band BeamCraft 600 in 2Q’18. Additional products supporting higher frequency bands including TDD will be available in 2H’18.

“Blue Danube’s portfolio of Massive MIMO products enables operators to flexibly customize RF energy to optimize capacity, coverage and cell edge performance.” said Mark Pinto, CEO & President of Blue Danube Systems. “Our 5G-ready architecture allows beam-based network management leading to virtualization of the network RF functions. By avoiding the rigidity imposed by other radio architectures, we are enabling a completely flexible RAN ecosystem.”


  • Blue Danube Systems is headed by Dr. Mark Pinto, who previously was was an executive vice president at Applied Materials, where he launched the company’s solar business. Earlier in his career, Dr. Pinto was CTO of the Lucent Microelectronics Group and general manager of a wireless/wireline product division.
  • The company was founded by Dr. Mihai Banu, who developed the Blue Danube concepts independently since 2006. Previously,  he was R&D director at Agere Systems, working on analog circuits, RF systems for wireless LANs and wireless circuits research, and before that was Head of the Communications Circuits Research department at Lucent Technologies.
  • Investors in Blue Danube Systems include Sequoia, Northgate, Silver Lake, and AT&T.

One Africa Network envisions a regional traffic exchange

The Smart Africa Alliance (SAA) and Global Voice Group (GVG) have agreed to build an African Regional Traffic Exchange and Financial Settlement (ARTEF) Platform as part of the One Africa Network (OAN) initiative.

The idea is to establish a harmonized African telecommunications framework that would give African countries the potential to make significant leaps in development through lower intra-region communication costs. For consumers, the goal would be to lower the costs of communications by eliminating roaming charges. This would boost intra-African traffic, leading to more trade and economic growth. Calls from one OAN country to another would not have to leave the OAN zone to incur international changes.

As Patrice Baker, CEO of GVG, pointed out: “The OAN is a major initiative for the socio-economic development of Africa. The idea of a free roaming zone and the necessity of establishing a harmonized African telecommunications framework has been discussed for many years across the continent. It is time now for action. As a technical partner and provider of the traffic exchange platform, GVG is strongly committed to assist SAA members in the successful implementation of the OAN.”

Oracle to open 12 new cloud data center regions worldwide

Oracle announced plans to significantly expand its cloud infrastructure footprint by opening 12 new data center regions worldwide. The company seeks to increase the breadth and depth of Oracle Cloud services available across Asia, Europe, and the Americas.

The regional expansion will include locations in Asia including China, India, Japan, Saudi Arabia, Singapore, and South Korea; Europe including Amsterdam and Switzerland; and North America including two in Canada and two new US locations to support U.S. Department of Defense workloads.

Oracle's portfolio includes the breadth of cloud services (SaaS, PaaS, and IaaS) and new services in security, Blockchain, and Artificial Intelligence.

“The future of IT is autonomous. With our expanded, modern data centers, Oracle is uniquely suited to deliver the most autonomous technologies in the world,” said Oracle CEO Mark Hurd. “As we invest, our margins will continue to expand. And with our global datacenter expansion, we are able to help customers lower IT costs, mitigate risks and compete like they never have before.”

In addition, Oracle announced the industry’s first end-to-end financially backed cloud warranty for Infrastructure-as-a-Service (IaaS). Oracle said it is now the only cloud infrastructure provider offering guaranteed service levels across performance, manageability, and availability: the three key characteristics defining how enterprises measure cloud infrastructure providers. Under terms of the new performance SLA, Oracle Cloud Infrastructure guarantees it will deliver more than 90 percent of published performance every day in a given month. If it falls below that level for even as few as 44 minutes a month, customers may claim service credits according to Oracle’s terms of service.

“No cloud provider in the world can match what Oracle guarantees,” said Thomas Kurian, President of Product Development, Oracle. “Our competitors offer narrow commitments and countless exclusions in fine print while Oracle’s SLAs deliver an industry first: guaranteed performance, manageability and availability in the cloud.”

NEC develops digital beamforming for 5G in 28GHZ band

NEC has successfully tested a new digital beamforming transmission method that uses a massive-element active antenna base station and 28 GHz band spectrum.

The demo is described as the simultaneous beamforming transmission (four multi-user MIMO) from a single massive-element active antenna system (AAS) to four terminals.  NEC achieved a 3.1 Gbps cell throughput by applying a frequency bandwidth of 300 MHz.
 
NEC said its massive-element AAS, supporting a 28 GHz band, adopts a fully digital control system, which improves the precision of beamforming. The fully digital control system enables simultaneous beamforming in multiple directions from a single massive-element AAS unit and efficiently implements high-speed and high-capacity communication without interfering with adjacent users through spatial multiplexing.

The beamforming takes into account multipath, a non-direct wave signal, and moderately adjusts beam directions as needed. It also cancels out interference through multipath and reduces performance deterioration caused by inter-cell interference.

NEC enables its advanced beamforming without digital/analog signal and frequency converters. Instead, the massive-element AAS adopts a fully digital control system with less power and more compact conversion functions.

"In order to effectively implement sophisticated services that apply 5G features from 2020 onward, it is essential to utilize 28 GHz and other high frequency radio bands, which enable the securing of wide bandwidth, and the utilization of beamforming," said Katsumi Tanoue, Deputy General Manager, Wireless Access Solution Division, NEC Corporation. "Moving forward, NEC will continue its efforts in development and demonstration tests for a massive-element active antenna base station system that delivers high speed, high capacity and massive connectivity."

Viavi supplies 5G test equipment to China Mobile

VIAVI Solutions is supplying 5G test and measurement solutions to China Mobile, which aims to introduce 5G service in China by the end of 2019. VIAVI said it is a preferred vendor of China Mobile, supporting their specific technologies and aggressive roadmap with advanced test solutions. These include Slicing Packet Network (SPN) with FlexE interface, the technology the carrier is positioning for 5G transport.

Viavi said CMCC has determined that Slicing Packet Network (SPN) is an optimal technology to support next-generation architecture, bandwidth, traffic model, network slicing, latency and time synchronization. Flexible Ethernet or FlexE is used in conjunction with SPN to create smaller Ethernet channels from a larger one, or vice versa, to guarantee quality of service (QoS) and isolation between slices at the transport layer. CMCC has requested that the ITU undertake standardization of SPN. VIAVI is committing to support CMCC by delivering an SPN test platform, establishing a common foundation for network equipment manufacturers, chip developers and transceiver vendors to validate products based on this technology.

Combining Ride Hailing, Smart Cities, and Networking – part 1

Preamble: The world’s largest ride-hailing service is integrating its “DiDi Smart Transportation Brain” with the traffic planning authority in Beijing and other major Chinese cities to optimize the routing of its vehicles and lessen urban congestion. The AI system will pull data from traffic sensors and connected vehicles in a massive network application that will require the most advanced mobile and backhaul network.

On an average day, DiDi Chuxing, the ride-hailing service that acquired Uber China in August 2016, is enabling up to 25 million rides. Its app has been downloaded more than 450 million times. By the company’s reckoning, this makes it the world’s leading mobile transportation platform. There are over 21 million drivers in China signed up for DiDi and by some estimates, 80% of taxi fares in the big cities are now booked via its app.

DiDi has moved well beyond basic car rides. Its app now lets the user pick from a range of transportation options: Taxi, Express, Premier, Luxe, Hitch, Bus, Minibus, Designated Driving, Car Rental, Enterprise Solutions and even Bike-Sharing though the ubiquitous bluegogo brand. Hiring a bike on a short-term basis no longer requires a deposit –just the DiDi app and a valid user account. DiDi is now a simple and cashless way of travelling through China’s municipalities.

Business is booming too for Uber.  However, Uber and to some extent Lyft often finds itself in contentious relationships with the communities it serves. In the UK, Uber is beset by numerous legal and social difficulties. In September, Transport for London, stripped Uber of its license, accusing the company of being “unfit to operate.”  Last week, a protest against Uber by London black cab drivers caused gridlock across the city. Other municipalities are taking action as well. The City of York is the third British municipality that has acted to strip Uber of its license. In the EU, a recent ruling from the European court of justice (ECJ) has determined that Uber is a taxi operator and not an information service, requiring it to accept stricter regulation and licensing terms.  Even in its home market, Uber faces a slew of lawsuits from investors, ex-employees, customers and cities for a list of management missteps, improprieties, questionable business practices, data breaches and possibly criminal behaviour.

In contrast, DiDi Chuxing enjoys the implied endorsement of the Chinese government and the investment of all three of China’s Internet giants – Alibaba, Baidu, and Tencent – as well as Apple and dozens of other high-profile investors. Better yet, there is a regulatory framework for the company to grow.  In July 2016, China became the first country to officially legalize ridesharing. This came about when seven of China's ministries, including the Ministry of Transport, jointly published "Preliminary Rules on the Management of Online Car-Booking".

DiDi Chuxing, which is headquartered in Beijing, was founded in 2012 by Cheng Wei, a former employee of Alibaba. The company’s inception came approximately three years after Garrett Camp and Travis Kalanick established Uber, but in many ways, its brief life as a business has been just as eventful and even more meteoric.

From the outset, there were local rivals backed by various tech giants and a series of price wars. There were also protests by established taxi companies and their drivers. To gain size and stature, a merger with the biggest rival was necessary, followed by the acquisition of Uber China in August 2016, a deal that some called a forced marriage and others a marriage of convenience. (Uber retained a 5.89% interest in DiDi Chuxing, while DiDi Chuxing also got a minority interest in Uber Global).  The deal effectively consolidated the market in China, leaving this one big player and a much simpler regulatory job for government authorities.

DiDi Chuxing recent milestones
• Completed 7.43 billion rides in 2017. Launched accessible vehicles services with UNDP for disadvantaged people.
• Established a partnership with Stanford Artificial Intelligence Laboratory.
• Started new joint venture projects to build EV charging networks.
• DiDi Labs opens new campus in Mountain View.

Ericsson says 5G RAN software will be ready by Q4

Ericsson announced that its 5G Radio Access Network (RAN) software, based on the recently approved first 3GPP 5G New Radio (NR) standard, will be commercially available by Q4 2018, paving the way for operators to launch commercial services in 2019. The 5G radio network software complements Ericsson’s already launched baseband and 5G radios. The company says all of the base radios from the Ericsson Radio System delivered since 2015 will be 5G NR-capable by a remote software installation.

Ericsson’s 5G radio network software promises multi-band support for global deployment and will allow operators to use new frequency spectrum as it becomes available. It also introduces a new category of radio products called Street Macro – a new site type that addresses the need of operators to grow in cities with limited available radio locations. The idea is to place radios on building facades with a smaller footprint but the necessary strength to secure network efficiency and coverage. Ericsson is also adding new radios with Massive MIMO technology.

Ericsson also announced enhancements to its Distributed Cloud architecture, which support cloud application deployment across multiple sites - central, distributed, and edge. The design can be managed, orchestrated, and perceived as one solution in what the company calls "Software Defined Infrastructure (SDI) to the edge". In addition, the Ericsson Distributed Cloud will add support for hardware options in a multi-vendor framework.

Fredrik Jejdling, Executive Vice President and Head of Business Area Networks at Ericsson, says: “Operators who want to be early with 5G now have the essential pieces for launching 5G networks already this year. With our expanded platform, they will get more efficient networks as well as opportunities to create new revenues from emerging consumer and industrial use cases.”

Switch backs Gigawatt Nevada -- largest solar project in U.S.

Plans were unveiled for Gigawatt Nevada, an initiative to build the single largest solar project portfolio in the United States, by Switch and Capital Dynamics.

Switch is a leading co-location data center operator with massive facilities in Nevada including its flagship campus in Las Vegas and a new campus in Reno. The company also has a marquee data center in Grand Rapids, Michigan and is building another regional data center in Atlanta.

The Gigawatt 1 assets will be owned and developed by Capital Dynamics, the second largest owner of solar projects in the country.  Gigawatt 1 anchor tenants will include Switch and several of its Switch CORE client. The project is negotiating with multiple private and public sector access customers within Nevada and outside the state.

Gigawatt 1 is projecting energy costs substantially less than the renewable energy from NV Energy (Nevada Power).


“The foundation of Gigawatt Nevada is that Nevada should harness the sun the same way Alaska harnesses its oil to significantly benefit all Nevadans,” Rob Roy said.  “Nevada enjoys the best solar window in the nation and so we Nevadans should not only be using solar for ourselves, but exporting it throughout the Western U.S. to create new jobs, tax revenue, economic diversification, and raise energy independence.”

“Climate scientists have repeatedly warned that we must move to renewable energy as rapidly as possible, but many monopoly utilities continue to hold us back from making this transition,” said Gary Cook, Senior IT Sector Analyst and Energy Campaigner at Greenpeace.  “Gigawatt 1 shows that when Switch and other leading companies don’t take ‘no’ for an answer, they can work together and kick open the door to large-scale sources of renewable energy that are better for the planet, and better for the economy in Nevada.”
