AT&T Extends its NetBond between clouds

AT&T NetBond is introducing a "cloud-to-cloud" feature that efficiently moves workloads across highly secure connections between public, private and hybrid cloud services in the NetBond for Cloud ecosystem.

AT&T NetBond for Cloud promises scalable network connectivity for efficient traffic flow between clouds. AT&T said that with this feature, each ecosystem cloud – private or public – can now be efficiently connected to another and remain off internet. Customers can easily manage connections between clouds by using the digital AT&T cloud portal. Network managers no longer have the time-consuming manual task of working with multiple cloud providers to build connection points individually – they can now create or change connectivity configurations within minutes.

“Many businesses use 3 or more clouds. And they’re often a mix of public, private or hybrid,” said Roman Pacewicz, Chief Product Officer, AT&T Business. “No matter the combination, it can be challenging if cloud environments have to mix. An important part is enabling efficient and highly secure network connections that help customers move their workflows between cloud endpoints. With NetBond for Cloud, it’s simple.”

Security options are available to manage the flow between end users and applications that can be used with the cloud to cloud feature. Our NetBond for Cloud service is fully off-internet, providing simple, highly secure access to industry-leading cloud services from virtually anywhere.

AT&T Tests Single Wavelength 400G Ethernet

AT&T completed testing a single-wavelength 400 gigabit Ethernet (GbE) circuit across its production network.

The multi-step trial used open-sourced white boxes to act as network equipment. AT&T said this aligns with its move toward an open, software-centric network.

“Introducing 400 GbE is a natural next step. Customer demands have shifted to faster speeds, more video-centric content and cloud integration,” said Roman Pacewicz, chief product officer, AT&T Business.

“This industry-first also aligns with our shift toward an open and software-centric network. Utilizing open-source controller technology, the end-to-end service transported across the AT&T OpenROADM metro network – using optical gear from Ciena, a developer of next-generation coherent optical solutions – provides further flexibility and cost-effective services for customers. Prior to this successful trial, all other field demonstrations have required multiple wavelengths to create a 400 GbE connection."

http://www.att.com

In October 2016, AT&T announced plans to conduct 400 Gigabit Ethernet testing in 3 phases:

  • Phase 1: Will use optical gear from Coriant to carry a true 400GbE service across a long-distance span of AT&T global backbone from New York to Washington, demonstrating that AT&T’s nationwide software-centric network is 400G-ready.
  • Phase 2: Will trial a 400GbE on a single 400G wavelength across AT&T’s OpenROADM metro network. We’ll use optical gear from Ciena, a developer of next-generation coherent optical solutions, to show the network is ready to transport 400GbE to serve our customers in a metro area.
  • Phase 3: Will test the first instance of a 400GbE open router platform. The “disaggregated router” platform uses merchant silicon and open source software – another industry first.

AT&T's fixed 5G trial expands to more cities

In a show of confidence in 5G, AT&T announced the expansion of its fixed wireless 5G trials to business and residential customers in Waco, Texas; Kalamazoo, Michigan; and South Bend, Indiana by the end of the year. Trial participants in the new markets may include universities, hospitals, churches, restaurants, and other small businesses. Participants will be able to stream premium live TV via DIRECTV NOW and experience faster broadband services, all over a 5G internet connection.

AT&T has been running a 5G field trial in Austin, Texas for some time. In June, this trial was expanded to included fixed 5G connections to various types of businesses and residences. The company said this testing reveals insights into millimeter wave (mmWave) performance and propagation, including variance for foliage, building materials, device placement, the surrounding environment and how weather impacts the signal and system. The testing showed speeds up to 1 Gigabit per second and latency rates well under 10 milliseconds for the radio link at customer trial locations in Austin.  AT&T is also conducting outdoor pre-standards mobile 5G testing.

AT&T said that the expanded field testing in Waco, Kalamazoo, and South Bend will increase the number of participants and expand the physical footprint. The company hopes to begin standards based deployment as early as late 2018.

“In Austin, we see all types of weather and substantial foliage,” said Marachel Knight, senior vice president, Wireless Network Architecture and Design, AT&T. “Taking our fixed wireless 5G trials out of the lab and into the real world helps us learn important factors about mmWave and 5G. And in doing so, we’re learning how to better design our network for the future.”

“We’ve been testing and demonstrating 5G technologies with AT&T for over a year and now we’re expanding the scope of our trial to AT&T customers in Waco,” said Joakim Sorelius, head of Product Area Network Systems at Ericsson. “Ericsson is providing an end to end solution that includes new 28GHz radios, virtualized RAN and a full 5G virtualized Core. By testing the technologies in the live commercial-like environment and trialing new 5G use cases together, we are able to gain valuable experience in preparation for commercial deployments based on 3GPP New Radio (NR) technology.”

AT&T preps for its mega-merger with Time Warner – Part 2

Part 1 of this article covered operational metrics from AT&T's Q2 2017 financial report. This week, AT&T confirmed that its $109 billion blockbuster acquisition with Time Warner is on track and likely to close by the end of the year. Although the company did not explicitly say that regulators, including the Department of Justice and the FCC, are likely to approve the merger, one can presume that no major issues have been presented yet that could threaten the deal. As the first mega-merger to face review under the Trump Administration, it has not been exactly clear what level of objections such mergers might face, especially under a president who routinely attacks CNN (a Time Warner property) as 'fake news'. Under the Obama administration, AT&T was blocked from acquiring T-Mobile US because the combination was seen as market consolidation that would be detrimental to consumers.

Key terms of the AT&T – Time Warner combination

As a reminder, AT&T officially announced its intention to acquire Time Warner on October 22, 2016. The deal was to be structured as a stock-and-cash transaction valued at $107.50 per share, representing a transaction value of $108.7 billion. The companies said the reason for the deal is to combine Time Warner's library of content and ability to create new premium content with AT&T's extensive customer relationships, world’s largest pay TV subscriber base and scale in TV, mobile and broadband distribution. Time Warner, which was formed in 1990 through the merger of Time Inc. and Warner Communications, encompasses many premium media properties, including HBO, New Line Cinema, Turner Broadcasting System, The CW Television Network, Warner Bros., CNN, Cartoon Network, Boomerang, Adult Swim, DC Comics, Warner Bros. Animation, Castle Rock Entertainment, Cartoon Network Studios, Esporte Interativo, Hanna-Barbera Productions, Warner Bros. Interactive Entertainment. It also owns 10% of Hulu.

The basic idea driving the merger is for Time Warner to act as the content arm for AT&T, providing mobile and fixed broadband line subscribers with valuable material as part of packaged service bundle. Consumers presumably would purchase an AT&T service bundle based on the perceived quality and value of the package rather than simply the lowest price for mobile connectivity. This will allow ARPU to rise and ensure a 'stickiness' factor that goes beyond the latest mobile handset deals, currently a leading cause for subscriber churn.

As a content provider, Time Warner requires far less ongoing capital expenditures than AT&T, which must invest routinely in its infrastructure. AT&T has stated that it expects $1 billion in annual run rate cost synergies within 3 years of the deal closing due to cuts in corporate and procurement expenditures. As there is little overlap between the companies, its not clear where these savings would come from. Time Warner does maintain its corporate headquarters in high-priced Manhattan, but this is where significant content transactions are negotiated and it is unlikely to be relocated to Dallas.

Rising debt load

One outcome of a combined AT&T and Time Warner is that the investor profile will be very different. An article this week by Bloomberg points out that after the merger is completed, AT&T's net debt will rise to $182 billion. This will transform AT&T into a more leveraged conglomerate, putting much greater pressure on how management can use free cash flow from operations. Over the past few years, AT&T has been using significant amounts of cash to buy back its own shares, thus increasing shareholder value. AT&T has also been one the more generous corporations in terms share dividends, reportedly returning 70% of free cash flow last year, or about $11.8 billion, according to Bloomberg. Going forward, more cash will be needed to service the heavier debt load, so we might expect that less cash will be available for dividends or share buybacks.

Betting on bundling

For the deal to be a success, AT&T and Time Warner will have to generate some real synergy in the minds of consumers. With Net Neutrality principles no longer an area of focus for the FCC under the new chairman, Ajit Pai, AT&T will have more leeway in positioning special service packages for its subscribers. For instance, home entertainment services may be the first big use case for 5G networks starting in 2019. A mobile operator such as AT&T might launch a 4K TV package for residential consumers in certain markets. With connection speeds in the hundreds of megabits, AT&T could deliver a strong 5G TV service featuring exclusive shows from HBO or Castle Rock Entertainment, while also including in the package regular LTE smartphone connectivity for all members of a household. Such an offer would be unmatched by rivals such as Sprint and Comcast.

There is already some movement in this direction. AT&T is ready to launch a 5G video trial with DIRECTV NOW service in Austin, Texas. The trial will evaluate how fixed wireless mmWave technology handles heavy video traffic. Previously, AT&T reported that its 5G lab trials were achieving speeds up to 14 Gbit/s and latency of under 3 milliseconds.

But how is video bundling working so far for AT&T? In July 2015, AT&T completed its acquisition of DIRECTV, making it the largest pay TV provider in the U.S. with more than 26 million customers in the U.S. and millions more in Latin America, including Mexico and the Caribbean. The implied total equity value of this deal was $48.5 billion although the total transaction value was $67.1 billion, including DIRECTV's net debt.

The DIRECTV acquisition also brought exclusive, premier content, particularly live sports programming to AT&T, including exclusive pay TV rights to NFL SUNDAY TICKET, ownership of ROOT SPORTS Networks and minority stakes in the Game Show Network, MLB Network, NHL Network and the Sundance Channel. Soon after completing the merger, AT&T began offering bundles combining cellular service, satellite-TV or U-serve TV over FTTH (in certain markets). These offers have been widely promoted via TV and print advertising, in the carrier's retail stores, and in notices to AT&T's millions of mobile users.

On a regular basis since then, AT&T execs have described the merger as a 'hit', citing higher ARPU from consumers who take both services. By Q2 2016, AT&T added nearly 1 million DIRECTV subscribers. In more recent quarters, this moment appears to have stalled, perhaps because the pay TV segment is no longer growing as more cord-cutting consumers look to over-the-top (OTT) services instead of traditional satellite TV subscriptions. Operating metrics for Q2 showed a loss of DirecTV and U-verse TV subscribers in the quarter. However, AT&T’s over-the-top DirecTV Now service continues to add subscribers every quarter and now stands at 491,000 users. So, if hardware-based bundling is capex intensive and no longer growing, perhaps OTT packages are the way to go.

AT&T partners with Ericsson for 5G trial of DIRECTV NOW in Austin

AT&T, which last year completed what it claimed to be the first fixed wireless 5G business customer trial in Austin, has announced the launch of a second trial involving the use of millimetre wave (mmWave) technology to deliver high speed 5G network services to more locations in Austin, Texas.

AT&T's second trial is designed to provide an ultra-fast Internet connection to residential, small business and enterprise locations utilising Ericsson's 5G RAN and the Intel 5G Mobile Trial Platform. Trial participants will be able to stream premium live TV via DIRECTV NOW and access faster broadband services over a fixed wireless 5G connection.

AT&T believes that the trial will provide speeds of up to 1 Gbit/s using mmWave spectrum. It noted that earlier this year it successfully delivered DIRECTV NOW utilising mmWave technology at its Middletown lab in New Jersey, which was claimed to be the first time DIRECTV NOW had been delivered over a 5G connection.

The latest trial covers a variety of customers, such as residential, small business and enterprise, and by using DIRECTV NOW and other applications AT&T is seeking to gain further insights into mmWave performance characteristics and better understand the need for standards development.

The fixed wireless 5G trial in Austin is due to last for several months. AT&T will also continue 5G testing using its network testbeds. At the same time, the company will continue its research into the role of software-defined networks and experimenting with advanced virtualised-RAN core network capabilities during the year.


The operator stated that data traffic on its mobile network has increased by more than 250,000% since 2007, with video now constituting more than half of mobile data traffic. In addition, video traffic has risen by over 75% and smartphones were responsible for nearly 75% of data traffic carried in 2016.

AT&T to launch software-based 10G XGS-PON trial

AT&T announced it will conduct a 10 Gbit/s XGS-PON field trial in late 2017 as it progresses with plans to virtualise access functions within the last mile network.

The next-generation PON trial is designed to deliver multi-gigabit Internet speeds to consumer and business customers, and to enable all services, including 5G wireless infrastructure, to be converged onto a single network.

AT&T noted that XGS-PON is a fixed wavelength symmetrical 10 Gbit/s passive optic network technology that can coexist with the current GPON technology. The technology can provide 4x the downstream bandwidth of the existing system, and is as cost-effective to deploy as GPON. As part of its network virtualisation initiative, AT&T plans to place some XGS-PON in the cloud with software leveraging open hardware and software designs to speed development.
AT&T has worked with ON.Lab to develop and test ONOS (Open Network Operating System) and VOLTHA (Virtual Optical Line Terminator Hardware Abstraction) software. This technology allows the lower level details of the silicon to be hidden. AT&T stated that it has also submitted a number of open white box XGS OLT designs to the Open Compute Project (OCP) and is currently working with the project to gain approval for the solutions.

The company noted that interoperability is a key element of its Open Access strategy, and prompted the creation of an OpenOMCI specification, which provides an interoperable interface between the OLT and the home devices. This specification, which forms a key part of software-defined network (SDN) and network function virtualisation (NFV), has been distributed to standards and open source communities.



  • AT&T joined OCP in January 2016 to support its network transformation program. Earlier this year at the OCP Summit Edgecore Networks, a provider of open networking solutions and a subsidiary of Accton Technology, announced design contributions to OCP including a 25 Gigabit Ethernet top-of-rack switch and high-density 100 Gigabit Ethernet spine switch. The company also showcased new open hardware platforms.
  • At the summit, Edgecore displayed a disaggregated virtual OLT for PON deployment at up to 10 Gbit/ based on the AT&T Open XGS-PON 1 RU OLT specification that was contributed to the OCP Telco working group.
  • Edgecore's ASFvOLT16 disaggregated virtual OLT is based on the AT&T Open XGS-PON 1 RU OLT specification and features Broadcom StrataDNX switch and PON MAC SOC silicon, offering 16 ports of XGS-PON or NG-PON2, with 4 x QSFP28 ports and designed for next generation PON deployments and R-CORD telecom infrastructure.

AT&T and China Telecom sign partnership deal

AT&T and China Telecom announced they have signed a framework agreement that strengthens their cooperation to support the development of advanced network services for multinational companies operating in China.

Through the agreement, the companies will help multinational customers leverage secure global communications to support business growth in China and worldwide. AT&T and China Telecom will also jointly work to create new services in the areas of Internet of Things (IoT), cloud-based big data, Voice over LTE (VoLTE) roaming, and software-defined networks (SDN).

The companies noted that the new agreement renews the 20-year authorisation under which Shanghai Symphony Telecommunications (SST), the joint venture formed bAT&T, China Telecom and Shanghai Information Investments, was established in 2000. As part of the new agreement, the parties intend to expand the scope of SST and the locations it serves to enable the delivery of new business services and technologies to customers.

Specifically, under the renewed agreement the companies plan to:

1.         Help establish industry standards for SDN and support their adoption.

2.         Launch bilateral roaming tests, as contemplated in a previously executed roaming agreement for business customers.

3.         Explore the potential of VoLTE roaming.

AT&T Demos 650 Mbit/s using LTE + LAA

AT&T and Ericsson announced that they have conducted a live LTE-LAA technology field trial, during which initial wireless data rates of more than 650 Mbit/s were achieved in downtown San Francisco.

AT&T noted that LTE-LAA technology is expected to play a key role in its push to achieve theoretical peak speeds of 1 Gbit/s at selected small cell sites by the end of this year. In addition, the technology also constitutes a key element as the operator works to upgrade the network and increase speeds in its 5G Evolution markets.

The operator stated that while 5G standards are yet to be finalised, it is seeking to lay the foundation for future wireless networks leveraging the 5G Evolution program and technologies including LTE-LAA as it aims to begin delivering 5G wireless data speeds as early as late 2018.

AT&T previously demonstrated the ultra-fast speeds enabled by LTE-LAA at Mobile World Congress in Barcelona, where it showed mobile user speeds of up to 1 Gbit/s utilising LTE-LAA combined with carrier aggregation, 4 x 4 MIMO and 256QAM.

LTE-LAA combines unlicensed spectrum with licensed spectrum through carrier aggregation to increase overall network capacity and enable faster, more reliable wireless speeds. The technology is designed to co-exist with other unlicensed spectrum technologies such as WiFi via a feature termed 'listen before talk', which allows fair coexistence between LTE-LAA and WiFi.



  • AT&T announced in April that as part of its 5G Evolution program it planned to begin offering higher speed, lower latency services for wireless customers with the latest devices in 20+ major metro areas by the end of the year. The new wireless capability was initially available in parts of Austin, where AT&T wireless customers with a Samsung Galaxy S8 or S8+ are able to access faster 5G Evolution Internet speeds.
  • AT&T stated at that time that the higher speed service would be expanded to Indianapolis in the summer, with plans to extend it to markets including Atlanta, Boston, Chicago, Los Angeles, Nashville and San Francisco.

AT&T launches fixed wireless Internet in 8 states

AT&T announced that its Fixed Wireless Internet for rural and underserved locations is now available in a further eight states, expanding on the initial launch of the service in Georgia in April this year.

With the latest launch, the AT&T fixed wireless Internet service is available to more than 70,000 locations across underserved or unserved areas in the 9 states. AT&T noted that the service expansion is part of its FCC Connect America Fund (CAF) commitment, through which it plans to serve a total of over 400,000 locations by the end of 2017 and more than 1.1 million locations by 2020.
The states where the fixed wireless Internet service is being launched are as follows: Alabama; Florida; Kentucky; Mississippi; North Carolina; South Carolina; Tennessee; and Louisiana.

AT&T stated that it plans to expand the service to 18 states overall during 2017, including Arkansas, California, Illinois, Indiana, Kansas, Michigan, Ohio, Texas and Wisconsin. AT&T plans to reach a total of more than 67,000 locations across Georgia using fixed wireless technology by 2020.



  • AT&T's fixed wireless Internet service provides a home Internet connection for customers in rural and underserved areas and offers a minimum download speed of 10 Mbit/s. The connection is delivered from a wireless tower to a fixed antenna located at the customers' homes or businesses.
  • AT&T announced in January that following trials of fixed wireless Internet (FWI) service in 2016 in a number of states as part of efforts to expand access to rural locations with slow or no Internet connectivity via its participation in the CAF II program, it would launch FWI in areas where it had accepted CAF support.

FirstNet and AT&T detail progress

FirstNet and AT&T, which in April announced a partnership for the deployment of a national high-speed data and voice network for first responders, have detailed State Plans for U.S. states and territories to support the roll-out of the FirstNet network.

The companies noted that the State Plans are being delivered three months ahead of the original schedule and represent a milestone in the deployment of the FirstNet network. The State Plans are being released via an online portal, while states and territories will have up to 45 days to review the plans. States and territories will be able to exchange feedback with FirstNet prior to an official 90-day period for governors to make an 'opt-in/opt-out' decision on their state plans.

A decision by a state/territory to opt-in will allow FirstNet and AT&T to immediately begin delivering services to the state or territory's public safety community, as well as enabling infrastructure investments for the network.

The partners stated that when a governor opts-in, FirstNet and AT&T will launch the network build process, thereby prompting:

1. Transfer of the financial, operational and technical risks of building, maintaining and upgrading the FirstNet network in that state/territory to AT&T for a period of 25 years.

2.         The launch of key network features, including priority access to voice and data across the existing nationwide AT&T LTE network.

3. The provision of pre-emption over the AT&T LTE network, which is due to be enabled by year-end, meaning that fire, police and EMS will have dedicated access to the network when necessary.

4. The delivery of new feature-rich services at competitive rates.


  • AT&T announced in April that it had been selected by the First Responder Network Authority (FirstNet) to build and manage the first broadband network dedicated to U.S. police, firefighters and emergency medical services (EMS) across 50 states, 5 U.S. territories and the District of Columbia.

  • Under the terms of the 25-year agreement, FirstNet was to provide 20 MHz of telecoms spectrum and payments of $6.5 billion over the next five years to support the network build-out, while AT&T was to invest approximately $40 billion over the term of the contract to build, deploy, operate and maintain the network.

How to Scale IoT?



There are two stages to scaling IoT solutions, says Mobeen Khan, IoT Strategy& Project Management, AT&T.  The first happens during the prototyping and second when you've figured out what you are going to build and now need to deploy hundreds of thousands of end devices.
