Nokia demonstrations at SCTE•ISBE Cable-Tec Expo 2019

The future of cable networks

This interactive, HTML-based demo depicts how the environment for cable services is changing and how cable networks must adapt.The demo will show how the Nokia broad end to-end portfolio of products and solutions can be used in future cable networks to deliver new levels of operational flexibility, innovative services and exceptional customer experience. Based on various use case examples associated with key cable operator needs, it shows how Nokia products and technologies can be applied to cable’s 10G initiative, cable 5G and wireless services, next-generation operations and service agility, customer experience transformation, smart home/Internet of Things (IoT) and more.

MSO edge cloud

Cloud computing is transforming the MSO landscape, offering flexibility and lower total costs, high service availability, the ability to run network functions at the edge and offer very high throughput and low latency applications to their customers. Cloud capabilities must be distributed across the network to form an edge cloud, which places computing resources where the traffic is — at the edge of the network. This demonstration would include the Nokia Open Compute Platform (OCP), an ultra-small footprint provided by the Edge Cloud solution. This solution is complemented by real-time optimized, OPNFV compatible cloud infrastructure with OpenStack distribution built to run in small data centers while providing the performance and low latency required by solutions like Cloud RAN, vCMTS and distributed gateway functions such as Wireless Access Gateway, virtual residential gateway and mobile gateway. It offers the solution with ease of deployment using remote upgrade automation and configuration management.

Application demonstration will include edge video orchestration, VR 360 and Scene analytics. The Nokia Edge Video Orchestration (EVO) application creates a new multimedia experience for end users at event locations; for example, sports arenas, racetracks, concerts and congress venues. Video content is locally produced, orchestrated and distributed to the visitor audience and, as the majority of tasks are executed in close proximity to the event location (“hotspot”), the solution contributes significantly to network efficiency improvements. The VR 360 application stitches video feeds from multiple cameras and the content is optimized, packaged and distributed from the multi-access edge computing (MEC) platform to devices (VR headsets).

With cameras now being turned into IoT sensors, multiple data sources are combined by the Nokia Scene Analytics to analyze these various streams to detect any anomalies. It discovers on its own what is “out of the norm” and only records the video that is important to review. Under ordinary circumstances there would be the need for personnel to review reams of video to detect a problem, which is an unmanageable task. Scene Analytics makes the unmanageable manageable.

The edge cloud will be a fundamental asset for service providers to support new services and applications, opening new vertical market opportunities.

Wireless solutions for cable

As MSOs are in the process of implementing their wireless strategies, the following use cases will be presented.

  1. Nokia CBRS Radio Access Solution can help cable operators provide fixed wireless access (FWA) to residential and enterprise customers. The deployments will be outdoors on designated towers, side walls, poles and/or rooftops. AZQC (4x5W) will serve as the radio of choice for FWA applications. In the future, Nokia will introduce a 64T64R Massive MIMO product at the CBRS band as well, to further increase capacity and coverage.
  2. Mobile offload: By deploying LTE on the CBRS band, the cable operator can offload significant user traffic from their mobile virtual network operator (MVNO) partner’s network and substantially reduce roaming charges. Nokia can help customers implement the traditional macro cell architecture or the all-in-one small cell deployment, depending on the objectives and constraints.
  3. Private LTE: Enterprises today must support real-time interactions with operations, employees, customers, partners and suppliers anywhere and at any time. Private LTE, which is sometimes referred to as Dedicated LTE and Enterprise LTE, offers enterprises full control of all data traffic and applications. Private LTE networks allow enterprises to integrate machines, sensors, people, vehicles and things with a very high level of security, service reliability and performance to meet the requirements of almost all industry vertical applications.
  4. IoT: Networks will enable IoT and applications such as Smart Cities, analytics applications for asset-intensive industries, and other industry 4.0 applications.

Nokia equipment/demos

a. AZQC, Massive MIMO solution:
Nokia AZQC radio is currently the flagship CBRS macro radio that supports 4x5W transmission over 80 MHz of OBW within the 3550–3700 MHz CBRS frequency band. It supports simultaneous operations of LTE and 5G NR carriers. At <6.5 L and 7.5 kg, AZQC is a very compact unit that can be easily mounted on walls, poles or rooftops. Nokia is also planning to introduce the next generation 64T64R Massive MIMO version of CBRS radio that will further boost output power, eliminate the need for external antennas and increase overall coverage and capacity.

Nokia provides high performance CBRS customer premises equipment (CPE) to establish network connectivity with the base station. The Nokia CBRS CPE has compact form factor (9 in x 9 in x 1.2 in) that makes it easy to install. The fixed beam antenna has 15 dBi of gain and maximizes throughput within the cell site coverage area.

c. Multi-band indoor and outdoor unit (MBI/MBO) small cells:
Finding new sites for traditional macro cells is increasingly complex and expensive. Small cells will play a critical role in providing operators with a solution that can be easily and quickly deployed in strategic locations to add capacity and coverage. These smaller radius sites will be characterized by “light” deployment principles involving low-cost, easily available locations such as light poles, traffic lights, building walls and street level shelters. The critical enablers for these lighter deployments are base station size, low power consumption, wireless backhaul and “all-in-one box” solutions. Nokia has the broadest range of small cells product portfolios on the market. All-in-one Flexi Zone BTS provides specific capacity and coverage with macro-like performance and feature parity.

d. Single box, strand mount small cell for CBRS (prototype):
The Nokia FW2QQC is an all-in-one BTS solution that has all the benefits of the regular multi-band outdoor small cell mentioned above, but with a mechanical design adjustment to make it strand mountable and supports DOCSIS 3.1 backhaul using an adjunct Lindsay outdoor gateway box. It is the perfect solution for cable operators to build wireless coverage wherever cable strands are available.

e. Nokia Integrated Operations Center for IoT/Smart Cities:
The Nokia Integrated Operations Center (IOC) for public safety is designed to meet the needs of public safety agencies faced with growing responsibilities and a transition from voice-based to broadband data-centric emergency response. The IOC enables rapid, coordinated and fact-based decision making, by making use of video communications, IoT, analytics and automation. Virtual emergency response centers help to coordinate decision making, balance workloads and support multiagency interworking.

End-to-End (E2E)/Turnkey services for cable (Wi-Fi and wireless)

Nokia will be presenting some of their service capabilities for deploying large heterogenous wireless access networks. These include:

  • Determining high value sites (SCORE), RF design, analytics tools
  • Site acquisition, construction, system integration
  • Maintain and operate and build-operate-transfer (BOT) models

Today’s wireless networks are characterized by the need to deploy large numbers of base stations capable of providing sufficient coverage and capacity for end-customer satisfaction. Higher density areas require smaller cells, often located at street level, which create significant challenges for operators in terms of performance and cost.

The Nokia SCORE process is an innovative service solution that helps determine the best value sites for deployment of wireless base stations. By evaluating the impact of various site options in terms of RF performance and cost, Nokia can rank various site options in terms of their effective relative value in the wireless network, thus allowing an operator to choose the most appropriate sites for the network.

The SCORE process is underpinned by the Nokia high precision RF prediction tools and the hetnet engine room (HER) system that leverages soft auditing capabilities, physical databases and fiber mapping to predict accurate deployment cost estimates.

The highly flexible SCORE process supports multiple wireless technologies and site providers, including municipalities. Nokia looks forward to engaging in discussions with operators about the SCORE process and the ability to choose the best value sites for your wireless system deployment.

vDAA Unified Cable Access solution

Cable operators are facing competing pressures as never before. Consumers and businesses are demanding ever more bandwidth, more responsive networks, increased reliability, new services and more. As MSOs strive to meet their customers’ demands, they must contend with business challenges demanding that they reduce capital and operating expenses, simplify their infrastructure, build new revenue generating services, increase service velocity and future-proof their networks.

To accomplish this, most MSOs are progressing toward a Distributed Access Architecture (DAA), moving typical headend/hub functions closer to the end user, eliminating cable specific hardware and digitizing the headend-to-node link. The Nokia Unified Cable Access and vDAA solution implements a virtualized cable modem termination system (CMTS) for even greater efficiency and flexibility.

The Unified Cable Access (UCA) solution section of Nokia’s booth at SCTE Cable-Tec Expo will showcase some of the advanced technologies necessary to meet customer and MSO goals.

Low latency DOCSIS

Many current and future web-based applications require both high bandwidth and low latency. CableLabs developed the Low Latency DOCSIS (LLD) specification to address latency issues related to both queuing delay and media acquisition delay. A key method for managing queuing delay is to use a dual queue in combination with Low Latency Low Loss Scalable Throughput (L4S), which is based on Data Center TCP (DCTCP), a scalable congestion control used in data centers for very high throughputs with ultra-low delay and loss. L4S improves many current applications (e.g., web browsing, video chat) and will enable many future applications (e.g., HD video conferencing, cloud-rendered interactive video, cloud-rendered virtual, reality, augmented reality, remote presence with remote control and more).

The L4S technology and its benefits will be explained in this interactive demo in which visitors can load up an emulated broadband internet access with numerous interactive multimedia applications and enjoy remarkably and predictably low queuing delay, giving unprecedented interactivity for all applications at the same site, even under heavy load.


DOCSIS 3.1 includes orthogonal frequency division multiplex (OFDM) and orthogonal frequency division multiple access (OFDMA), a new physical layer technology delivering better spectral efficiency than SC-QAM. This important technology, and the increased scaling and performance it enables, will be demonstrated with live traffic flowing across a Gainspeed access node implementing DOCSIS 3.1.

Video core

Delivering traditional QAM video in a DAA does not work because the link between the headend/hub and the node is digital, and the QAM modulation is performed in the node itself. For cable operators not immediately transitioning to all-IP video, an alternative method of delivering QAM video must be employed. One option is to use a video core, which is an auxiliary core as defined by the CableLabs Flexible MAC Architecture (FMA) standards. The video core performs all the functions of an EQAM except the modulation and PHY, which are performed by the DAA node. This demo will better explain this approach utilizing an AppearTV video core to send video across a live Gainspeed DAA node to a TV with a QAM receiver.

IP video over DPoE

Some MSOs are making the changeover to all-IP video concurrent with their evolution to a DAA. Many MSOs are running fiber to the home (FTTH), especially in greenfield deployments. The Nokia Unified Cable Access solution enables both HFC/DOCSIS and EPON/DPoE nodes to be managed by a single Gainspeed Access Controller. This demonstration will highlight this capability and show IP video delivered through a Gainspeed EPON/DPoE fiber access node to a Nokia ONU.

R-PHY interoperability

The Nokia Gainspeed family of products and vDAA is “FMA-ready” — designed to be compliant with the CableLabs FMA specification. This enables a cable operator to use the Gainspeed Access Controller and vCMTS in conjunction with other standards-compliant remote PHY nodes. In this demonstration, we will show how the Gainspeed Access Controller and virtualized CMTS interoperate with third-party remote PHY devices (RPD).

Gainspeed family of products

On display will be an array of products that are part of the Nokia cable offerings and UCA solution including the Gainspeed Access Controller, vCMTS, Video Engine, HFC/DOCSIS and fiber/DPoE nodes and more.

5G transport from an MSO perspective

RAN technology is evolving with 5G, from distributed to centralized and cloud architectures. Centralization and the “cloudification” of baseband processing can bring technical and economic benefits. However, there are challenges. As we move toward 5G, a wide range of RAN options will coexist, creating higher service demands on all parts of the transport network — fronthaul, mid-haul and backhaul for the mobile network operators MNOs).

In this presentation, Nokia will describe different options for MSOs to provide wholesale services to MNOs, across a range of service business models spanning fronthaul, mid-haul and backhaul deployment scenarios. For MNOs seeking front haul connectivity directly to/from the radio tower, optimized solutions include cell site routers using IXR-E, and time sensitive packet switch (TPS) for fronthaul connections back to DU/CU/BBU nodes. Mid-haul and backhaul solutions include SR-2 aggregation routers, optimized WDM line systems, and 100G/400G coherent transceivers.

Transport for MSO Distributed Access Architecture

Nokia solutions enabling an end-to-end Converged Interconnect Network (CIN) for DAA/Deep Fiber solutions will be on display. This display includes solutions for metro/regional optical transport networks, providing scalable bandwidth from 100G to 600G per wavelength, bandwidth agility and survivability with advanced wavelength switched line systems, and future-proof and open infrastructure that can scale to support next generation optics, including 800G+ per wavelength transport and 100G/400G transceivers. Optical transport solutions for DAA access to RPD/RMD nodes include cost-effective and low footprint optical line systems that support 10G DWDM deployment today and scaling to 100G coherent transceivers in the future. Packet access aggregation devices in environmentally hardened clamshell designs that can be deployed in an outdoor strand, on a pole, or on pedestal mounting configurations and supporting packet aggregation of 10G traffic from RPD/RMD will enable migration to CIN/DAA architectures with greater bandwidth efficiency closer to the network edge, while support for 100G/400G pluggable coherent transceivers with extended reach enable hub bypass.

Analytics and automation

Network Services Platform: This demo provides an overview of the Nokia Network Services Platform (NSP) with focus on the latest advancements in network automation, programmability and optimization. It also provides a preview of forward-looking capabilities that incorporate machine learning concepts and assurance automation.

Nokia Deepfield: We will be demonstrating the Nokia Deepfield Network Firewall (DNF). The DNF will demonstrate a workflow that can be used with whitelists to permit traffic for critical internet infrastructure, minimizing false positives. Due to the Nokia patented Secure Genome solution, we have a good understanding of how the internet works, which IPs are part of critical infrastructure, and which IPs have been part of botnets. The DNF can also use this information to create blacklist CIDR lists to drop, or rate-limit traffic during an attack. The same workflow can be used to create inspection policies to create dynamic mirror policies to create a looking glass. We will create IP filters that use the Nokia FP4 network processors unmatched payload capability, and with real-time telemetry streaming, we will get feedback about the filter entries.

Cloud security and intelligence: Nokia will demonstrate cognitive security orchestration with dynamic monitoring, advance analytics and closed loop automation with identity and access management paired with malware detection to identify threats before they find their way to high value assets. The demo highlights automation of response by using cyber playbooks to defend modern attacks such as distributed denial of service (DDoS), advanced persistent threats, malware, ransomware or IoT attacks. Machine learning, cognitive analytics and automation are central to this solution with high levels of accuracy achieved to reduce the false positives in alarm management and to handle a large volume of alerts. Also, on display will be the Nokia Netguard Audit Compliance Manager, a next configuration management solution and Certificate Life Cycle Manager, a tool for life cycle management of certificates issued by multivendor Certificate Authorities.

The Nokia evolved Service Operations Center (eSOC) solution combines network intelligence with service quality insights and customer/subscriber analytics. The result is automated, informed and effective operations. It automates less important aspects of network operations while efforts are prioritized on troubleshooting those issues that have the most impact on customer service quality.
