Net Transformation tackles a broad set of topics around operator efforts to evolve and otherwise transform their telecom networks in an effort to reduce complexity, keep costs in check and earn new revenues.
Summary Bullets: • DAS will face steep hurdles in evolving to the 5G era.
• Vendors of distributed small-cell enterprise RAN solutions, once content to aim down-market from DAS, are increasingly aimed at competing with DAS head-on, exploiting DAS’s 5G vulnerabilities.
• However, any threat posed to DAS by 5G is likely to take years to have effect, increasing the long-term uncertainty surrounding these trends.
5G — in its early implementations, at least, aimed at mobile broadband, rather than the Internet of Things (IoT) — will be more evolution than revolution, boosting speeds that were already increasing steadily via advances in LTE technology. But in at least one respect, even 5G mobile broadband promises to do something truly disruptive: It could mean the demise of DAS.
That’s no small matter. Some estimates put the global DAS market well north of $6 billion annually. Walk into any stadium, hospital, shopping mall, or big-box store and make a mobile call; odds are you’re using a DAS, a carrier-neutral network that distributes the signals of multiple operators using shared antennas and other gear so that each operator doesn’t need its own separate in-building network.Continue reading “How 5G Could Kill Distributed Antenna Systems (DAS)”→
• Segment Routing Deployed in a Backbone Network: Cisco and China Unicom collaboration, a two year endeavor, enables the operator’s nationwide MPLS VPN network to support on-demand services. Cisco notes that this represents China’s first Segment Routing (SR) deployment and leverages its SDN technologies to provide an end-to-end solution. SR also helps mitigate the use of more complicated IP protocols (like RSVP-TE), which is a big advantage and leverages the power of SDN’s centralized management model. .
• Advanced Vendor Services Accelerated Delivery: Cisco’s Advanced Services teams provided full life cycle support and coordination with China Unicom and third-party suppliers, and tackled SDN, NFV, cloud computing, ultra-broadband networking, and related technology issues for the operator. The use of vendor supplied services has always been part of the “vendor – operator” model, but virtualized technologies pose additional time-to-market issues such as mastering new technologies and dealing with the complexity of integrating multiple components.
The announcement by Cisco and China Unicom represents a tangible example of how current infrastructure networks can be transformed to deliver flexible cloud-based services by exploiting new routing and networking techniques, such as segment routing which aligns well with centralized management and control (i.e., SDN) paradigms. What makes the solution significant is the combination of multiple technologies, SR, SDN controllers, service orchestration, and the ability to quickly compute optimal traffic paths through an IP network using a path computation engine (PCE). Individual components on their own cannot deliver the resultant end-to-end solution, which supports China Unicom’s ability to offer a range of named cloud-based services (Cloud Network Connection, Cloud Networking, Cloud Broadband, Unicom Cloud Shield, Intelligent Boutique Video Network, and Boutique Financial Network) which it noted in a joint press release with Cisco.

Investments by numerous vendors over the past few years in ‘LiFi’ are resulting in meaningful progress in 2018. A trial announced by Philips Lighting in March represents a huge endorsement.
While the technology remains several years away from commercial products, LiFi represents a truly disruptive technology that could augment traditional cellular and WiFi.
News flash: With seemingly insatiable customer demand for high-speed data and streaming video, network operators are increasingly concerned about how they can keep pace. And much of that concern centers on ‘bandwidth.’ Traditional cellular radio technologies are constrained, and operators and regulators are scrambling to find new spectrum on which to provide service, particularly with the 5G era looming. WiFi provides an effective tool to extend cellular or fixed coverage into homes and businesses, but it is difficult to seamlessly integrate into other networks and is racked with security vulnerabilities.

PCS Maximizes Fiber Utilization: The PSE-3 DSP relies on PCS modulation to increase available bandwidth per fiber close to its theoretical maximum.
PSE-3 Simplifies Network Operations: PCS enables the PSE-3 to tune its wavelength capacity from 100G to 600G, using a single modulation format, baud rate, and channel size.
Nokia’s new Photonic Service Engine 3 (PSE-3) is designed to improve optical performance, flexibility, and programmability across a wide range of wavelength capacities. To achieve this, the new DSP chipset utilizes probabilistic constellation shaping (PCS) – a modulation technique which improves optical reach performance by approximately 1 dB, or roughly 25% (compared to the most advanced optical systems today). This brings the optical system performance, according to Nokia, within a fraction of a dB of Shannon theoretical limits.

• Automates Complex Network Slicing Process: The Contrail Network Slicing Bot aims to simplify the highly complex process of defining, creating, provisioning and managing network slicing across both physical and virtual infrastructures. Network slicing is a fundamental tenet of all 5G architectures.
• Addresses Skill Set Shortage: Juniper’s network Bots, including the Slicing Bot, help alleviate the lack of internal staff education and higher level skillsets required to use network automation tools, which are often complex and require deep network knowledge. The Slicing Bot uses a high level human friendly language to translate operator intent into actionable workflows.
Juniper’s “Slicing Bot” launch enables operators to leverage technologies such as machine learning, network telemetry and SDN control, to help reduce the complexity they face as they attempt to deploy virtual networks to meet the growing demand for faster time-to-service. The new Contrail Slicing Bot joins three other Bots, which the company launched in December 2017. The Bots enable operators to operate at a business level (i.e., intent) to help automate complex network functions that are often error prone and time consuming due to manual processes and the lack of operational skills. The three initial Bot applications offered by Juniper included PeerBot, TestBot and HealthBot, which address key pain points for operators; the new Slicing Bot tackles the highly complex, but essential process of carving up the network into virtual slices, a fundamental building block for supporting 5G services.

While the healthcare system in the United States, and abroad, is a complex ecosystem with an array of interdependencies that are influencing the way the market is evolving, four major trends are having a strong impact circa 2018.
Shifts towards “Value-based Care”. Particularly in the U.S., the healthcare system is faced with significant rising costs due to a very large portion of its population moving into retirement age. In response, the U.S. government, the largest payer in the healthcare ecosystem, is taking steps to shift reimbursements towards “value-based payments.” A central tenet of this approach is to encourage a shift in industry focus from “paying for procedures” to “paying for outcomes”. While the business impact of this trend is to transfer increasing amounts of financial risk from payers to providers and patients, the theory is that it will also result in more targeted and effective treatment and care plans.
The need to protect profitability. As the movement towards value-based care shifts more financial risks to providers, many are taking steps such as scaling up through M&A, opening practices in desirable geographies and investing in specialties to protect their profitability. For example, hospital systems are opening urgent care facilities in suburban and rural areas, drug companies are merging and/or buying retail pharmacies, and healthcare payers are partnering with health systems to help promote wellness programs.
Ericsson’s Q4 2017 results showed signs of progress, including significant adoption of its 5G-focused Ericsson Radio System (ERS), an improved position in the Chinese market, and the elimination or completion of a dozen unprofitable and/or non-strategic services engagements.
Unfortunately, the weak results, coupled with continued management upheaval, paint a picture of a company that remains adrift despite replacing a significant portion of its leadership team in the past 18 months.
Ericsson released its Q4 2017 financial results January 31, and as the company had already forecast, it was mostly bad news, particularly when it comes to reported results which reflected a 12% decline in revenue and a painful -34.5% operating margin compared to -0.3% in Q4 2016 and -10% in Q3 2017. However, in the spirit of seeing the light at the end of the tunnel, there was some good news to offset the bad. To be clear, however, some of the news was just bad.
