Samsung claims biggest share of Korea's 5G rollout

Equipment from Samsung Electronics Co. represents the largest share the recent 5G network rollouts from all three mobile operates in Korea.

Korean operators have been transmitting 5G signals in Seoul and metropolitan areas since December 1, 2018 using 5G base station radios and 5G core solutions from Samsung’s Networks Business unit.

Specifically, Samsung has supplied 5G core solutions and more than 53,000 5G radio base stations to Korea’s three operators. The deployments used Samsung’s 5G Massive-MIMO Unit (MMU) radio base station in the 3.5GHz spectrum. The ability to re-use existing sites has been key to enabling the Korean operators to deploy a 5G network consisting of tens of thousands of radios within just a few months since the December 1st launch.

The virtualized 5G core solutions, provided to all three Korean operators for their 5G commercial launch, support both legacy 4G networks and next-generation 5G services in Non-Standalone (NSA) mode. Samsung will support the migration to Standalone (SA) mode through a future software upgrade. Samsung’s solution implements many of the key technologies of 5G networks, such as Control and User Plane Separation (CUPS), which are essential for network operators to scale their networks and support the new services enabled by 5G technology.

“Korea is one of the first markets in the world in which the 5G experience is opening up for consumers, and we’re thrilled to play a key role in the nationwide rollout of 5G with our unparalleled 5G network solutions,” said Paul Kyungwhoon Cheun, Executive Vice President and Head of Networks Business at Samsung Electronics. “As a longstanding innovator in the 5G space and one of the few vendors offering a full end-to-end 5G solution, Samsung is at the forefront of pushing the limits of 5G and beyond.”

TNS and Metaswitch deliver Hosted Robocall Blocking Service

Transaction Network Services (TNS) and Metaswitch introduced Call Guardian Authentication Hub, a new hosted STIR/SHAKEN solution that provides carriers with a call authentication solution.

FCC Chairman Ajit Pai has challenged U.S. operators to adopt protocols that combat illegal spoofing and better protect subscribers from unwanted robocalls, or face regulatory action.

Call Guardian Authentication Hub is a fully managed service that combines the TNS Call Guardian analytics and robocall detection solution used by leading U.S. wireless and landline service providers with Metaswitch’s STIR/SHAKEN compliant MetaSphere QCall solution, which enables signing and verifying Caller ID. Metaswitch was the first vendor to both complete successful implementation of a STIR/SHAKEN caller ID authentication solution in the ATIS robocalling testbed and deploy in production with a Tier 1 provider in North America.

The Call Guardian Authentication Hub leverages TNS’ visibility into over 1 billion call events daily resulting from TNS’ connectivity with more than 500 North American carriers. While STIR/SHAKEN enables carriers to sign calls within their own network, the Call Guardian Authentication Hub simplifies signing of inter-carrier calls by automatically authenticating and verifying calls and applying the appropriate call validation treatment. It includes support for universal call blocking of illegal robocalls as defined by U.S. and Canadian regulators.

“For STIR/SHAKEN to dramatically reduce nefarious robocalls, call authentication must extend beyond the Tier 1 carriers that have the budget and resources not available to the hundreds of other smaller service providers,” said Bill Versen, Chief Product Officer at TNS. “Our combined solution with Metaswitch uniquely fills this market gap by offering any service provider operating in North America a feasible path towards rapidly deploying the STIR/SHAKEN call authentication framework.”

While leading U.S. carriers are moving towards STIR/SHAKEN implementation, a majority of cross-carrier U.S. wireless voice traffic does not exclusively transit the networks of the largest carriers, allowing bad actor robocallers to simply continue originating traffic from Tier 2 and 3 carrier networks that do not deploy STIR/SHAKEN compliant solutions. At the same time, Canadian Telecommunications Service Providers (TSPs) have a requirement to implement authentication and verification of caller ID information for Internet Protocol (IP) voice calls to empower Canadians to better protect themselves against nuisance calls.

“As the 2019 TNS Robocall Investigation Report found, only 10% of high risk robocalls come from Tier 1 carriers, which is why carriers of all sizes, as well as telecom regulatory authorities recognize how critical STIR/SHAKEN is to protect their business and consumer subscribers and restore trust in voice calling,” stated Shriraj Gaglani, EVP, Business & Corporate Development, Metaswitch. “Instead of spending months on interoperability testing and other cost-intensive components of STIR/SHAKEN implementation and deployment, carriers can deploy the Call Guardian Authentication Hub in a matter of days.”

An additional capability of this service allows operators to identify and apply treatment to spoofed calls that have traversed non-IP networks or do not have STIR/SHAKEN framework deployed. This multi-layered approach maximizes the effectiveness of the solution.

The Hawaiki transpacific cable is a 15,000 km fiber optic deep-sea, carrier-neutral cable with a design capacity of 67 Tbps. Hawaiki went live in July 2018.

“Choosing the WBX in Seattle was a natural but strategic decision for us,” said Remi Galasso, Chief Executive Officer, Hawaiki. “With over 250 carriers, cloud, and content providers within their ecosystem we could not have found a more ideal location.”

NETSCOUT trims quarterly outlook citing delayed project

NETSCOUT SYSTEMS announced preliminary financial results for its fourth quarter and fiscal year ended March 31, 2019 below previous guidance.

The company now expects 4Q FY2019 revenue to be approximately $15 million lower than originally anticipated, primarily due to delayed revenue recognition on a large service assurance project at an international mobile operator. However, NETSCOUT anticipates a solid quarterly GAAP and non-GAAP EPS performance due to healthy gross margins resulting from a more favorable product mix and lower operating costs.

Anil Singhal, NETSCOUT’s president and CEO, stated, “Our fourth-quarter fiscal year 2019 revenue shortfall was primarily caused by a longer-than-expected implementation schedule for the largest phase of a $15 million project at an international mobile operator, which delayed revenue recognition. Nevertheless, we expect that the revenue associated with this phase of our customer’s project will be recognized within the next several quarters. Despite this delay, we produced another quarter of solid top-line results in our enterprise customer segment and experienced a relatively strong performance in our security product area. Healthy gross margins aided by good adoption of our software-centric offerings and cost controls throughout the year played important roles in our ability to successfully achieve our prior EPS guidance.”

Singhal concluded, “As we move forward, we believe that the most severe headwinds impacting our revenue performance in recent years have largely subsided, and we remain focused on executing key elements of our strategy that we believe are integral to driving improved, sustainable financial performance. Our plans for fiscal year 2020 anticipate both organic top-line growth and EPS growth. We will share more insight when we report our full-year fiscal year 2019 results next month.

Google's Dunant cable leverages SDM for 250 Tbps capacity

Google's Dunant submarine cable system, which will link the U.S. and France, will be the first subsea cable to leverage space-division multiplexing (SDM), enabling 250 terabits per second capacity.

In a blog posting, Vijay Vusirikala, Director of Network Architecture and Optical Engineering at Google, says SDM will increase cable capacity in a cost-effective manner.

Dunant's design uses twelve fiber pairs and power-optimized repeaters. Whereas traditional subsea cables are powered from the shore end and rely on a dedicated set of pump lasers to amplify the optical signal for each fiber pair, SDM allows pump lasers and associated optical components to be shared among multiple fiber pairs.

Orange joins Google's Dunant transatlantic cable project

Orange is joining Google's Dunant transatlantic project, which is a 6,600km submarine cable connecting the United States to the French Atlantic coast. The system is expected to be ready for services late 2020.

As the French landing partner, Orange will build and operate the landing station on the French Atlantic coast and provide the backhaul service to Paris. In parallel, Orange will benefit from fiber-pairs with a capacity of more than 30 Tbps per pair.

Google to build private "Dunant" cable from Virginia to France

Google is planning a new transatlantic subsea cable system linking the east coast of the United States to Europe to bolster its global network.

Dunant, which is named in honor of Swiss businessman and humanitarian Henri Dunant, will be a four-fiber pair cable system spanning over 6,400km from Virginia Beach to the French Atlantic coast.

Google has selected TE SubCom to build the Dunant submarine cable system. Activation is expected in late 2020.

Henri Dunant was the founder of the Red Cross and recipient of the first Nobel Peace Prize.




SubCom confirms next gen SDM high fiber count undersea systems

SubCom confirmed the manufacturing and installation of next-generation SDM high fiber count (HFC) undersea systems. The company’s repeaters incorporate SDM technology with an HFC solution that utilizes pump sharing amplifier architecture for increased system reliability and optimized cost-effective capacity. This flexible architecture allows every amplifier to be supported by a combination of pump lasers, thus providing maximum overall capacity across 12FP, 16FP and 24FP trunk and branch segments.

SubCom also confirmed that its Wavelength Selective Switch (WSS) ROADM technology is now in production. WSS filter technology supports fully-flexible, reconfigurable routing of the optical spectrum on each fiber pair. This flexibility allows customers to dynamically reassign the optical spectrum between trunk and branches throughout the system’s life to achieve maximum value. Further flexibility is achieved using SubCom’s enhanced branching units (eBU) for optical path switching on up to 24FP branches.

To drive improvements in cable manufacturing, optical assembly and system integration, SubCom is using the latest tools and technologies at its factory in New Hampshire.

“We’re proud to consistently provide our customers with robust, future-proofed products that enable cable systems to operate at their peak performance over many years,” said David Coughlan, CEO of SubCom. “Our customers have peace of mind knowing that our strong optical and marine engineering offer them the best value for their investment. Getting the wet plant right and having the best products, installation and maintenance technology is the key to ensuring long-term, successful operation.”

Lean NFV proposes a Key-Value Store to simplify deployments

A new industry initiative known as Lean NFV is aiming to simplify the process of onboarding virtualized network functions (VNFs).

Six years after the publication of the first Network Functions Virtualization (NFV) specification, proponents of Lean NFV argue that the technology has failed to live up to its promises largely due to complexity and inefficiency in the deployment model.

The topic was addressed in a keynote at last week's Open Networking Summit in San Jose presented by Scott Shenker, Professor of Computer Science, UC Berkeley; Sylvia Ratnasamy, Associate Professor of Computer Science at UC Berkeley & CTO of Nefeli Networks; and Constantine Polychronopoulos, VP & CTO of the Telco Business Unit at  VMware. 

Specifically, complexity in the current deployment model arises in three areas:  when the NFV manager is integrated with the existing computational infrastructure, when VNFs are integrated with the NFV manager, and when coordination is required between the various components of the NFV manager.

Lean NFV is advocating a key-value (KV) store to serve as a universal point of integration for VNFs. Many open source key-value store implementations have been deployed by companies such as Google, IBM, LinkedIn, Redis, etc.

The goal with Lean NFV is to allow NFV solutions to be “plugged in” to any computational infrastructure. With this model, principles, an NFV manager is responsible for the management of both individual VNFs and end-to-end service chains, including lifecycle management tasks such as placement, launching, configuring, chaining, scaling, healing, monitoring, and upgrades. KV-based integration also allows VNFs to evolve incrementally and independently.

Lean NFV argues this model is synergistic to ETSI MANO and supportive of the work being done with ONAP, the network automation platform of the Linux Foundation. Furthermore, the model scales for the network slicing and microservices requirements in full 5G architecture.

A whitepaper on this topic is published here:

UK operators: Huawei ban would bring heavy cost

A restriction placed on Huawei in the telecom supply chain could delay a full 5G launch by between 18 and 24 months and cost the UK economy between £4.5bn and £6.8bn, according to a study published by Mobile UK, which is the trade association for the UK’s mobile network operators -  EE, O2, Three and Vodafone.

The study argues that a delay to 5G rollout while operators make alternative procurement arrangements with other suppliers may seriously threaten the UK’s aspiration to be a world leader in 5G, something that has been central to the UK government’s industrial strategy since 2016.



The report also provides the following summary of 5G plans

EE
EE plans to activate 5G sites in 16 UK cities in 2019. The first launch cities will be the UK’s four capital cities – London, Cardiff, Edinburgh and Belfast – and Birmingham and Manchester. As well as the six launch cities, through 2019 EE will also be introducing 5G across the busiest parts of ten more UK cities: Glasgow, Newcastle, Liverpool, Leeds, Hull, Sheffield, Nottingham, Leicester, Coventry and Bristol. The first 1,500 sites that EE is upgrading to 5G in 2019 carry 25% of all data across the whole network, covering 15% of the UK population. EE will launch with multiple smartphone partners, as well as an EE 5G home router with external antenna, to showcase the power of 5G for broadband. 

O2 
O2 will begin the roll-out of its 5G network in 2019 in Belfast, Cardiff, Edinburgh and London. Other areas of the UK will see roll-out from 2020 to coincide with the wider availability of 5G handsets.

Three 
Three will launch 5G in H2 2019 with a data-only Fixed Wireless Access (FWA) product as part of a £2bn network investment. The initial launch will be in London and other major cities where they see value to be greatest. This forms part of Three’s tiering strategy – to upgrade the busiest sites on its network. 

Vodafone 
Vodafone are already trialling 5G in Birmingham, Bristol, Cardiff, Glasgow, Liverpool, London and Manchester and will be delivering 5G to Birkenhead, Blackpool, Bournemouth, Guildford, Newbury, Portsmouth, Plymouth, Reading, Southampton, Stoke-on-Trent, Warrington and Wolverhampton later in 2019.
