Nokia and Etisalat have set a capacity record during the world’s first field trial of single-carrier terabit-per-second data transmission on a deployed fiber network.
A terabit-per-second is enough bandwidth to download the entire Game of Thrones video series in HD in under two seconds. This comes as Etisalat is investing heavily in its core network infrastructure in anticipation of the massive increase in traffic from high bandwidth services.
The Nokia field trial demonstrates that Etisalat’s existing network can support the higher optical wavelength bit rates that will be required to support high-bandwidth services such as 5G extreme mobile broadband (very fast wireless to the mobile), fiber-to-the-home (FTTH) and Data Center Interconnect (DCI) cloud services.
Higher bit rates per wavelength provide power and space savings, improved network simplicity, increased spectral efficiency and capacity, and ultimately reduced cost per bit compared to optical networks composed of lower rate channels.
The trial successfully transmitted a record 50.8 terabits per second using multiple wavelengths, each with a net information rate of 1.3 terabits per second, over a 93-km fiber route of Etisalat’s wavelength division multiplexing (WDM) network. Leveraging a single optical carrier operating at 100 Gigabaud, the terabit wavelengths employed Nokia Bell Labs-pioneered probabilistic constellation shaping, or PCS, to intelligently shape the signal to achieve maximum capacity for the specific fiber route. Nokia’s Photonic Service Engine 3 – now shipping to customers as part of Nokia’s 1830 portfolio – is the first coherent digital signal processor to implement PCS.
Esmaeel Alhammadi, Senior Vice President, Network Development at Etisalat, said, "We are pleased to have partnered with Nokia Bell Labs to demonstrate that our optical network is capable of transporting a terabit per second over a single wavelength, and a total per-fiber capacity of over 50 terabits-per-second. Increasing network capacity helps us to provide bandwidth-hungry services such as 5G extreme mobile broadband, fiber-to-the-home and DCI for enterprises.”
Sam Bucci, Head of Optical Networking at Nokia, said, “The introduction of 5G will require a network that can support dramatic increases in bandwidth in a dynamic fashion. This ground-breaking trial with Etisalat is testimony to Nokia’s commitment to continue to invest in coherent and optical component technologies required to meet the 5G networking challenge at the lowest total cost of ownership for our customers.”
Nokia has a long history of advancing the frontiers of optical transmission. It was the first to demonstrate single-carrier 100G transmission in a deployed production network in 2007, and the first to commercialize single-carrier 100G and 200G wavelengths in 2010 and 2013, respectively. More recently, the Nokia Bell Labs optical research team published the world’s first terabit-per-second transmission lab trials in 2015 and 2017. By extending these records to a deployed operator network, Nokia Bell Labs is bringing the age of terabit wavelength networks a big step closer to reality.
Details of the trial have been published in a post-deadline paper at the European Conference on Optical Communication, held last week in Dublin, Ireland.
Vodafone’s network was down across Europe on Thursday with thousands of customers unable to use the internet or make phone calls.
Issues began at around 14:42 BST according to network monitor Down detector. Customers all over the UK reported issues and so did customers in Spain, Ireland, Italy, Germany, Greece and Portugal.
Many customers took to Twitter to express their frustration on the matter.
Vodafone then acknowledged the outage and tweeted, “We are currently investigating a potential outage to our fixed and mobile services. We thank you for your patience as we work to get this resolved.”
The company has around 19.5 million UK customers and around 444 million globally.
Initially, it looked more like an isolated issue with customers in some UK cities thought to have been among those affected; however, Economics Correspondent Paul Cogan at Virgin Media TV noticed that Down Detector showed more maps with even more outages.
He stated, “Vodafone’s problems don’t seem to be restricted to just Europe. Down Detector outage maps show problems in India, Australia, New Zealand and Turkey.”
The global disruption was then confirmed when Vodafone Ghana tweeted, “Vodafone Ghana wishes to apologize for the intermittent network challenges experienced by some of our mobile customers. Resolving it remains our topmost priority. We shall keep you updated. Thanks for your patience.”
Vodafone then apologized for the inconvenience and said the services were back to normal. “This issue has now been fully resolved and normal service has been restored to customers. We thank you for your patience and sincerely apologize for the inconvenience caused.”
The network outage comes a month after Vodafone set its launch date for its new 5G network in seven UK cities.
The company last experienced an outage in October 2018.
A robust ecosystem is driving 5G deployments to support enhanced mobile broadband (eMBB) and fixed wireless access (FWA) use cases, which sets the stage for sophisticated 5G applications requiring low latency and high reliability.
UK telecommunication operators are pooling together in an effort to try and tackle the coverage issues afflicting rural areas.
Ericsson has launched its critical communications broadband portfolio for service providers. This will enable service providers to meet the business-critical and mission-critical needs of industries and public safety agencies as digitalization and modernization of land mobile radio communications increases.
When communication is disrupted by minutes, seconds, or even milliseconds, it can have huge consequences for business operations, or serious implications for public safety. The need for fast and reliable communication is therefore paramount.
Such critical communications are used in many areas: from first responders and nationwide emergency services to workforce safety in enterprises. There is a growing demand for business and mission-critical broadband for such use cases. Service providers need to deliver the highest level of availability, reliability and security to meet this demand.
To meet critical communications users’ needs, Ericsson has developed a new portfolio comprising three offerings: critical network capabilities; critical broadband applications;\ and flexible deployments for both local private networks, and nationwide mission-critical LTE networks.
Per Narvinger, Head of Product Area Networks, Ericsson, says: “We see growth opportunities for service providers and government operators by addressing new segments with LTE/5G networks. Our critical broadband portfolio will enable our customers to effectively secure the critical communication needs of sectors such as public safety, energy and utilities, transportation, and manufacturing.”
Critical network capabilities
This offering includes advanced features for critical network performance and covers the following: high network availability; multi-network operation with spectrum sharing techniques; and coverage and capacity for critical applications. It also includes network security capabilities that ensure network services are maintained even when the infrastructure is under attack. Finally, quality of service, priority and preemption all guarantee latency performance and capacity requirements during high load and congestion.
The critical network capabilities include new features that simplify the rollout of broadcasting services across nationwide areas. Another new feature enables radio access sites to operate in fallback mode, should the network connection fail. This offering also includes deployable systems that allow temporary coverage for disaster recovery and operations in rural areas without existing coverage.
Critical broadband applications
This offering covers Ericsson Group-Radio that provides mission-critical push-to-talk, data and video services. This will enable, for example, blue light personnel such as the police to be more effective in performing community services that require advanced mobile broadband.
Flexible deployments for private networks
New business models are emerging for industries. From owning and operating their own networks, critical industries are now procuring private networks and services that leverage service providers’ existing network assets and operations – without compromising required local control.
Ericsson’s flexible deployments for private networks range from network slicing to fully dedicated networks, enabling service providers to offer scalable, critical broadband network solutions and services for critical industries.
Ericsson also offers managed services for private networks, with solutions based on AI and automation that predict and prevent events while reducing OPEX. These solutions enable service providers to reduce time-to-market and onboard new industries, while securing critical service level agreements.
Critical broadband will enable industries to increase efficiency through the following: enhancing workforce productivity and safety; massive onboarding of devices and sensors; real-time location of assets and equipment; and data collection to boost equipment and personnel performance and avoid downtime.
KDDI, a leading telecommunications operator in Japan, is deploying Nokia's G.fast solution to apartments and multi-dwelling units (MDU) buildings to deliver ultra-broadband services to customers.
Reducing the need to install new fiber, Nokia's technology will enable KDDI to use existing copper lines in MDU buildings to deliver 830Mbps combined uplink and downlink speeds to customers.
To support customers' ultra-broadband needs, Japanese operators are using fiber where possible along with new technologies like G.fast for a large number of MDU locations where copper is already installed.
Developed by Nokia Bell Labs, G.fast uses vectoring technology to effectively reduce cross-talk interference that typically impacts data speeds over copper networks.
Providing support for Japan's VDSL2 specifications, Nokia's G.fast solution will minimize the impact to existing VDSL systems and enable operators to quickly upgrade their high-speed internet service to gigabit class through a simple CPE (customer premises equipment) replacement.
KDDI has been deploying Nokia's G.fast solution and has started its rollout of 'au Hikari MDU Type G'.
Teresa Mastrangelo, principal analyst at Broadband Trends said: "G.fast continues to be a preferred choice for operators seeking to deliver gigabit broadband services to MDUs as it eliminates many of the issues found with FTTH deployments such as building types and access. However, in Japan, deploying G.fast can be just as challenging as fiber due to the unique VDSL ecosystem and standards in place.
As one of the few vendors capable of supporting both the global and local Japanese VDSL standard, Nokia has been able to help KDDI capitalize on the benefits of G.fast and seamlessly scale and migrate their network with minimal disruption. This win is another great example for how G.fast technology is being used to quickly address customers need for greater broadband speeds."
Shigenari Saito, Administrative Officer, General Manager, Network Technology Development Division, Technology Sector, at KDDI said:
"KDDI already provides 10Gbps service for our 'au Hikari' FTTH customers, but the speed we can provide has been limited to 100Mbps service for MDUs where fiber is difficult to deploy. Nokia's G.fast solution enables us to connect existing 100Mbps users and new G.fast users under the same DPU (distribution point unit). This gives us the flexibility and economical path to meet the customer's demands for higher speed. Our decision to deploy Nokia G.fast is based on our long-term relationship and Nokia continues to be our long-term partner for delivering technology innovations."
Sandra Motley, president of Nokia's Fixed Networks Business Group, said: "Operators looking to quickly roll out new ultra-broadband services are increasingly adopting multi-technology strategies that allow them to maximize the use of both fiber and copper technologies. This is particularly true in some cases like inside an apartment building, where more traditional Fiber-to-the-Home solutions can be very challenging to deploy. We are excited to be working with KDDI to deploy our G.fast solution to deliver fiber-like speeds that will enhance the way customers experience their broadband services."
European telecommunications vendor Ericsson has compiled another comprehensive Mobility Report and the strategic forecast is projecting that 5G will reach 1.5bn subscriptions by 2024.
5G is expected to reach more than 40 percent global population coverage and 1.5 billion subscriptions for enhanced mobile broadband by the end of 2024. This will make 5G the fastest generation of cellular technology to be rolled out on a global scale, according to the latest edition of the Ericsson (NASDAQ: ERIC) Mobility Report.
Key drivers for 5G deployment include increased network capacity, lower cost per gigabyte and new use case requirements. North America and North East Asia are expected to lead the 5G uptake.
In North America, 5G subscriptions are forecast to account for 55 percent of mobile subscriptions by the end of 2024. In North East Asia, the corresponding forecast figure is more than 43 percent.
In Western Europe, 5G is forecast to account for some 30 percent of mobile subscriptions in the region by end of 2024.
The uptake of NB-IoT and Cat-M1 technologies is driving growth in the number of cellular IoT connections worldwide. Of the 4.1 billion cellular IoT connections forecast for 2024, North East Asia is expected to account for 2.7 billion – a figure reflecting both the ambition and size of the cellular IoT market in this region.
Diverse and evolving requirements across a wide range of use cases are prompting service providers to deploy both NB-IoT and Cat-M1 in their markets.
Mobile data traffic grew 79 percent between Q3 2017 and Q3 2018 – China a key engine
Mobile data traffic in Q3 2018 grew close to 79 percent year-on-year, which is the highest rate since 2013. Increased data-traffic-per-smartphone in North East Asia– mainly in China – has pushed the global figure notably higher.
With a traffic growth per smartphone of around 140 percent between end 2017 and end 2018, the region has the second highest data traffic per smartphone at 7.3 gigabytes per month. This is comparable to streaming HD video for around 10 hours per month.
North America still has the highest data traffic per smartphone, set to reach 8.6 gigabytes per month by the end of this year – which can be compared to streaming HD video for over 12 hours monthly.
Ericsson claims that between the timeframe of 2018-2024, total mobile data traffic is expected to increase by a factor of five, with 5G networks projected to carry 25 percent of mobile traffic by the end of the period.
Fredrik Jejdling, Executive Vice President and Head of Business Area Networks, says: “As 5G now hits the market, its coverage build-out and uptake in subscriptions are projected to be faster than for previous generations. At the same time, cellular IoT continues to grow strongly. What we are seeing is the start of fundamental changes that will impact not just the consumer market but many industries.”
The Mobility report also features articles on fixed wireless access and how to make it a reality, streaming video from megabits to gigabytes, and developing the smart wireless manufacturing market.
Ericsson and Russian service provider MTS have teamed up to provide a superior mobile broadband experience for hundreds of thousands of football fans attending the upcoming global soccer tournament in Russia, through Europe’s largest deployment of Massive MIMO (Multiple Input, Multiple Output) to date.
Whether in the stadiums, in fan zones, selected transportation hot spots, or at some of Russia’s most famous landmarks, fans will be able to enjoy higher data speeds in seven of the 11 tournament cities.
In Moscow alone, the deployment covers two stadiums and fan zones, Sheremetyevo airport, Red Square, Tverskaya Street and Gorky Central Park.
Saint Petersburg coverage includes stadium and fan zones, Dvortsovaya Square, and Moskovsky railway station. The other covered cities are Yekaterinburg, Kazan, Niznny Novgorod, Samara and Rostov-on-Don. Ericsson installed AIR 6468 for MTS at more than 40 sites across the seven cities.
Ericsson AIR 6468 is the industry’s first New Radio (NR)-capable radio designed for compatibility with the 5G New Radio standard while also supporting LTE. It features 64 transmit and 64 receive antennas enabling it to support our 5G plug-ins for both Massive MIMO and Multi-User MIMO.
Through the intelligent reuse of system resources, Massive MIMO improves capacity by transmitting data to multiple user devices using the same time and frequency resources with coordinated beam forming and beam steering.
Massive MIMO is making it easier for operators to evolve their networks for a 5G future. This includes Ericsson’s 5G Plug-ins, which are based on many of the breakthrough capabilities in our award-winning 5G Radio Test Bed and 5G Radio Prototypes, currently deployed in operator field trials.
Andrei Ushatsky, Vice President, Technology and IT, MTS, says: "This launch is one of Europe's largest Massive MIMO deployments, covering seven Russian cities, and is a major contribution by MTS in the preparation of the country's infrastructure for the global sporting event of the year. Our Massive MIMO technology, using Ericsson equipment, significantly increases network capacity, allowing tens of thousands of fans together in one place to enjoy high-speed mobile internet without any loss in speed or quality.”
Arun Bansal, Senior Vice President, Head of Europe and Latin America, Ericsson, says: “Hundreds of thousands of football-loving fans are about to experience ultra-high data speeds thanks to our Massive MIMO deployment for MTS across seven tournament cities. Data-demanding mobile connectivity is going to play a huge part in their tournament experiences, so we are delighted to team up with MTS to ensure they enjoy a mobile experience like never before, whether they are at the game, in a fan zone, or at other selected areas.”
More than 1.5 million international fans are expected in Russia across the month-long tournament, which gets underway on June 14 and ends on July 15.
Nokia and Zain Saudi Arabia are deploying Nokia's FastMile technology to provide a superior customer experience to Zain's customers. The deployment, the first for Nokia FastMile in the Middle East and Africa region, follows a successful trial of the technology which recorded speeds of 20 Mbps - significant considering the current demands on 4G networks - and provided seamless 4G macro network coverage to reach users located in a challenging environment.
Zain is deploying the technology in the western and southern region of the country and also in the cities of Jeddah and Makkah. Interestingly, the FastMile solution will not only be deployed in the typical rural environments, but more in suburban areas, where no fiber or copper network is available, using the 1800 MHz band.
"We are enthusiastic about the success of the Nokia FastMile trial and the subsequent deployment of the technology, which will help us address the problem of poor in-house coverage and provide a much-improved user experience,” said Eng. Sultan Abdulaziz AlDeghaither, Chief Technology Officer, Zain Saudi Arabia. “We are committed to providing the best-in-class quality of experience to our customers, and this project is a key step in that direction."
Service providers usually struggle with in-house coverage in a 4G network. Nokia FastMile allows them to improve in-house coverage and provide ultra-fast mobile broadband speeds to end-users by cost effectively re-using an existing macro network infrastructure. In this case, the increase in throughput will enable Zain to build additional revenue streams by launching new and innovative services, as well as help attract new subscribers.
"This deployment starts a new chapter in our longstanding relationship with Zain. We look forward to working with them to deliver a better broadband experience,” said Ali Al Jitawi, head of the Zain Saudi Arabia customer team at Nokia. “FastMile provides operators with an innovative way to re-use existing networks to meet growing broadband requirements. This deployment reinforces Zain's technology leadership, allowing it to use the latest technology solutions to meet the requirements of their customers."
Vodafone Germany said it plans to invest €2 billion in its fixed infrastructure as it moves to deliver gigabit fiber broadband to 13.7 million customers. The company said it aims to finish the investment by 2021 and will focus on three segments in cooperation with partner companies in Germany.
The network expansion and upgrade plays into Vodafone Germany’s aim to become a “leading converged communications operator” in the country. The operator said its enterprise-focused unit will bring fiber connectivity to 100,000 companies across 2,000 business parks at a cost of around €1.4 billion to €1.6 billion.
Vodafone Germany’s consumer operation, it said, will fork out €200 million to €400 million to expand its fiber network to reach 1 million homes in rural areas. The overall scheme will include €200 million invested into upgrading existing cable infrastructure to deliver gigabit speeds to Vodafone Germany’s cable base of 12.6 million.
Vodafone Germany CEO Hannes Ametsrejter said he was “excited to announce this transformation investment plan for Germany, which will bring gigabit broadband services to millions of consumers and business.”
Ametsrejter added, “The project is consistent with our strategic goal to become a leading converged communications operator in Germany, enabled by a best-in-class gigabit network infrastructure.”
The company’s fixed unit contributed 40 percent of service revenue in Germany in the opening quarter of its financial year, contributing €1 billion in quarterly earnings, according to Vodafone’s Q1 fiscal financial statement covering the three months to end June.
The investment is Vodafone’s largest since its £19 billion ‘Project Spring’ investment, a two-year strategy to improve its mobile infrastructure. The operator’s presence in Germany’s broadband market grew when in 2013 it acquired the country’s largest cable operator Kabel Deutschland for €7.7 billion.
