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.
Federated Wireless announced a consortium designed to stake out a growth position in the emerging private LTE/CBRS market.
The consortium as comprised is incomplete; however, the announcement should serve as a wakeup call to public network operators that have thus far not taken a strong position in private LTE.
Amid the flurry of announcements emerging from this week’s AWS re:Invent in Las Vegas, which is quickly becoming one of the most important networking events of the year, was the announcement of a private LTE network consortium that relies on a number of partners to enable fast deployment of industrial IoT applications. Specifically, the consortium, led by Federated, includes:
Federated Wireless – using its cloud-based Spectrum Controller to enable secure access to the 3.5 GHz band;
Ruckus – providing what it bills as the “industry’s first” indoor LTE access points to use the 3.5 GHz CBRS spectrum;
Athonet – which sells a cloud mobile core product specifically designed for private networks;
Amazon Web Services (AWS) – specifically, the AWS cloud IoT platform to connect, manage, and monitor IoT devices at scale (Athonet’s BubbleCloud resides on the AWS cloud).
• Samsung’s bold announcement of $160 billion investment in the future missed an opportunity to highlight its 5G mobile access infrastructure capabilities.
• At this crucial inflection point in the run-up to the 5G era, Samsung’s longtime-underdog RAN business shouldn’t take a back seat in high-level messaging.
Samsung this week announced sweeping plans to invest a total of KRW 180 trillion (or about $160 billion) over the next three years in future growth areas including artificial intelligence (AI), 5G, automotive electronics components, and biopharmaceuticals.
Given the intended impact of the announcement, it’s surprising that Samsung didn’t take the opportunity to make a stronger statement about its role in 5G mobile access infrastructure. True, the release does state that the Korea-based tech giant “will also invest aggressively to become a global player in the advanced markets for 5G chipsets and related devices and equipment.” If that last word can be read to include mobile networking gear, then at least part of a single word in the 820-word message was aimed at capturing 5G networking mind share – not exactly a ringing bell.

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.
