Nokia successful field trial of single-carrier, 50.8 terabit-per-second on Etisalat’s WDM fiber optic network

Nokia and Etisalat (UAE) report the completion of a multi-terabit-per-second, single-carrier data transmission over an operator-deployed fiber network in a field trial.  Nokia said in a press release that a terabit-per-second is enough bandwidth to download the entire “Game of Thrones” video series in HD in under two seconds.

Using Etisalat’s wavelength division multiplexing network, the companies were able to reach a transmission speed of 50.8 terabits per second over 93 kilometers of optical fiber.

Nokia said 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-kilometer fiber route of Etisalat’s wavelength division multiplexing (WDM) network.

The Nokia field trial showed that Etisalat’s existing network could support the higher optical wavelength bit rates that will be required to support high-bandwidth services such as 5G extreme mobile broadband, fiber-to-the-home (FTTH) and data center interconnect (DCI) cloud services.

Here are the key points:

  • Trial is the world’s first terabit-per-second, single-carrier data transmission over an operator deployed fiber network.
  • New transmission capacity record comes as Etisalat invests in core network infrastructure in anticipation of a new generation of high-bandwidth services.
  • Results move Nokia Bell Labs’ experimental lab records of terabit-per-second single-carrier transmission to a deployed operator network.

In addition to the speeds, higher bit rates per wavelength enable power and space savings, improved network simplicity, as well as increased spectral efficiency and capacity. It also enables reduced cost per bit compared to optical networks composed of lower rate channels, according to Nokia.

Using a single optical carrier operating at 100 Gigabaud, the terabit wavelengths tapped into Nokia Bell Labs’ probabilistic constellation shaping (PCS) to intelligently shape the signal to achieve maximum capacity for the specific fiber route. Nokia said its Photonic Service Engine 3 was 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-fibre capacity of over 50 terabits-per-second.  Increasing network capacity helps us to provide bandwidth-hungry services such as 5G extreme mobile broadband, fibre-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 Nokia trial with Etisalat were published in a post-deadline co-authored paper at the European Conference on Optical Communication (ECOC), held last week in Dublin, Ireland:

Verizon & Nokia demo “5G NR” transmission on a “commercial network”

Verizon and Nokia have completed the first over-the-air, end-to-end “5G NR” data transmission on a commercial 3GPP 5G New Radio (NR) network, the companies announced. The transmission was between commercially deployed Nokia radio equipment and Verizon’s 5G network core and millimeter wave spectrum to a Nokia test van parked in the downtown area of Washington, D.C.

…………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………..

Editor’s Note: 

“5G NR” is based on 3GPP release 15 spec, whereas it’s 3GPP release 16 (with parts of release 15) which will be submitted as a candidate IMT 2020 Radio Interface Technology (RIT) at the July 2019 ITU-R WP 5D meeting. Also, we don’t consider an end to end transmission using only Nokia endpoint terminals a “commercial network,” which is one in which there are many paying customers and endpoint terminals from several vendors (not just Nokia).

…………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………………..

Verizon and Nokia said that the transmission was another of their ongoing demonstrations of 5G NR technology. They expect to launch commercial 5G mobile service in 2019. In June, the two companies completed a series of outdoor data sessions over the 5G NR standard, and used multi-carrier aggregation to boost those signals into the gigabit-per-second range. Last month, Verizon and Nokia said they completed the first successful transmission of a 3GPP NR 5G signal to a receiver in a moving vehicle.“The cadence and frequency of these significant milestone achievements from Verizon and Nokia show just how quickly we’re taking the promise of 5G technology from the lab to the field and to the marketplace where our customers will ultimately use this revolutionary technology,” said Bill Stone, Verizon vice president, technology development and planning, in a prepared statement. “We said Verizon will be first to 5G, and our latest milestone moves us closer to fulfilling that promise.”

“Nokia and Verizon have had a tremendous summer for 5G innovations and technology advancements,” said Marc Rouanne, Nokia president mobile networks, in a prepared statement. “We are thrilled to be on the forefront of this new technology, helping Verizon make yet another significant stride towards becoming the first-mover to the market.”

The announcement followed Verizon and Nokia last month transmitting a pre-standard 5G signal between two radio sectors to a moving vehicle, calling the successful trial a “major 5G milestone”.

Verizon earlier announced it would launch 5G residential broadband service in Los Angeles, Sacramento, Houston and Indianapolis, in the second half of this year (based on Verizon’s proprietary spec), to be followed by a mobile 5G solution.  That’s all before the ITU-R IMT 2020 standards are finalized in late 2020.

Verizon & Nokia complete 3GPP NR vehicle handoff

Verizon and Nokia announced they were able to achieve a key milestone on the road to 5G: handing off a signal seamlessly to a vehicle traveling between two radio sectors.  The test took place at Nokia’s Murray Hill, N.J., campus. A data transmission at 28 GHz was sent from two 3GPP New Radio (NR) radios on a Nokia building to a vehicle outfitted with a receiver and equipment to measure transmission statistics. The vehicle traveled between the two radios, achieving seamless NR Layer 3 3GPP-compliant mobility hand off of the signal between the two sectors, intra-gNB and inter-DU, according to the companies.

5G Mobility Demo

Verizon said that the call mobility test involved a data transmission at 28 GHz that was sent from two 3GPP compliant NR radios on Nokia’s building, to a vehicle that had a receiver and test equipment to measure transmission information.

“The vehicle traveled between the two radios, achieving seamless 5G NR Layer 3 3GPP-compliant mobility handoff of the signal between the two sectors,” Verizon said, noting that these were intra-gNodeB and inter-distributed unit handovers.

“Unlike some of the incremental 5G technology announcements we’ve seen lately, tests like the one we conducted are significant advancements in the development of 5G technology,” said Bill Stone, vice president, Technology Development and Planning for Verizon, in a press release. “By taking these tests out of the lab and into the field, we’re replicating the experience users will ultimately have in a 5G mobility environment,” he added.

“We are pleased to showcase the acceleration of the mobile capabilities in 5G,” said Marc Rouanne, president, Mobile Networks, Nokia, in the release. “Enhanced mobile broadband is one of the first services being delivered on Nokia’s end-to-end 5G Future X portfolio. As a result, we can help our customers meet their early 5G deployment schedules and initial coverage demands.”

Verizon plans to be the first to launch 5G residential broadband service in four markets this year:  Los Angeles, Houston, Sacramento and Indianapolis.  Verizon CEO Hans Vestberg told CNBC the operator is going to be first in the world with 5G. “We are building everything right now,” he said, with 5G mobile phones due in the hands of consumers next year.

AT&T – Nokia Partnership for Reliable IoT Connectivity

AT&T is partnering with Nokia to provide reliable connectivity for the Internet of Things (IoT) devices.  Chris Penrose, the President of the IoT Solutions of AT&T, said the carrier’s enterprise customers will benefit from this partnership through the simplified adoption of IoT devices and the improved ability of the network operator to respond to the concerns of its customers. Furthermore, the carrier noted in its announcement that this partnership enables AT&T to address specific business concerns of companies using latest technologies including 5G network slicing.

Worldwide IoT Network Grid (WING), a service that is developed and managed by Nokia, will be used by AT&T.  WING assists network operators in managing IoT devices, securing connected appliances, and facilitating the billing of the carrier’s customers. Another advantage of utilizing Nokia’s WING service is that it allows AT&T’s customers to access the global IoT ecosystem and infrastructure of the Finnish tech firm. It is expected that the core network assets of Nokia’s WING service will become available in 20 different countries by 2020.

AT&T will also utilize its own cloud-based service dubbed as the Multi-Network Connect platform. This platform enables businesses to manage their IoT devices remotely using a variety of communication technologies, including 2G, 3G, 4G LTE, Low-Power Wide Area Network (LPWAN), and satellite. Aside from the compatibility with a variety of communications standards, the carrier claims that another benefit of using its Multi-Network Connect platform is the ability to manage and monitor the devices using a single portal.

The partnership will begin developing, testing and launching IoT offerings this year. Offerings will be available in more than 20 countries in Europe, Asia, North America, South America and the Middle East by the first quarter of 2020. The partners will target a number of industries, including transportation, health, manufacturing, retail, agriculture, utilities, consumer electronics and smart cities. The initiative will “help set the stage for the evolution to global 5G,” according to the companies.

More specifically, the partnership will:

  • Address specific business requirements through capabilities like 5G network slicing that allows a single network to be partitioned into multiple networks.
  • Meet local regulatory requirements for IoT devices.

This is not the only IoT partnership in which AT&T is involved. In February, the mega telco and Ericsson said that they are teaming  up for IoT device certification. The collaboration includes testing, verification and “white glove” assistance with regulatory approval process. The program is available in more than 150 countries.

Early last year, AT&T said that Carrier, one of the world’s largest appliance and equipment manufacturers (made famous by Donald Trump’s visit), will build AT&T’s IoT functionality into its heating, ventilation and cooling (HVAC) product line.
