One critical aspect of a successful 5G deployment is the mobile network operator’s ability to support user equipment, radio network, core network and management products that are manufactured by a multitude of device and network equipment vendors. The multiple connectivity options in 3GPP architecture for 5G have created several possible deployment alternatives.
The latest Ericsson Technology Review article argues that there is a significant risk of ecosystem fragmentation if too many different connectivity options are deployed. After considering all the options, the authors conclude that a deployment approach based on options 3 and 2 will reduce network upgrade cost and time, simplify interoperability between networks and devices, and enable a faster scaling of the 5G ecosystem.
With 5G bringing in new possibilities for operators across the globe, a higher capacity microwave backhaul becomes even more important to ensure high-quality mobile broadband. This year’s Ericsson Microwave Outlook report discusses how this demand can be met with advanced microwave technology, spectrum, combination with fiber, and machine intelligence.

To meet the requirements of use cases in areas such as the Internet of Things, AR/VR, Industry 4.0 and the automotive sector, operators need to be able to provide computing resources across the whole telco domain – all the way to the edge of the mobile network. Service exposure and APIs will play a key role in creating solutions that are both effective and cost efficient.
The latest Ericsson Technology Review article explores recent advances in the service exposure area that have resulted from the move toward 5G and the adoption of cloud-native principles, as well as the combination of Service-based Architecture, microservices and container technologies. It includes examples that illustrate how service exposure can be deployed in a multitude of locations, each with a different set of requirements that drive modularity and configurability needs.
Mobile data traffic volumes are expected to increase by a factor of four by 2025, and 45 percent of that traffic will be carried by 5G networks. To deliver on customer expectations in this rapidly changing environment, communication service providers must overcome challenges in three key areas: building sufficient capacity, resolving operational inefficiencies through automation and artificial intelligence, and improving service differentiation. This issue of ETR magazine provides insights about how to tackle all three.
BRIDGING THE GAP BETWEEN PHYSICAL AND DIGITAL REALITIES
The key role that connectivity plays in our personal and professional lives has never been more obvious than it is today.

NB-IoT: a sustainable technology for connecting billions of devicesEricsson
Under the umbrella of 3GPP, radio-access technologies for mobile broadband have evolved effectively to provide connectivity to billions of subscribers and things. Within this ecosystem, the standardization of a radio technology for massive MTC applications – narrowband IoT (NB-IoT) – is also evolving. The aim is for this technology to provide cost-effective connectivity to billions of IoT devices, supporting low power consumption, the use of low-cost devices, and provision of excellent coverage – all rolled out as software on top of existing LTE infrastructure. The design of NB-IoT mimics that of LTE, facilitating radio network evolution and efficient coexistence with MBB, reducing time to market, and reaping the benefits of standardization and economies of scale.
The IoT embeds a broad range of MTC applications, and among the different types, massive MTC – including applications like smart metering, agriculture and real estate monitoring – sets a number of performance targets for connectivity. Attempting to meet these IoT targets using a radio-access technology designed for mobile broadband, however, doesn't make economic sense. Networks that provide connectivity to massive MTC applications need a radio-access technology that can deliver widespread coverage and low power consumption, often in signal-challenged locations. Hence the need for narrowband-IoT (NB-IoT).
NB-IoT is a 3GPP radio-access technology designed to meet the connectivity requirements for massive MTC applications, as well as the design targets for IoT including low device cost, extended coverage, 40 devices per household, long battery life, and uplink latency of under 10 seconds.
NB-IoT enjoys all the benefits of licensed spectrum, the feature richness of EPC, and the overall ecosystem spread of 3GPP. At the same time, NB-IoT has been designed to meet the challenging TCO structure of the IoT market.
This articles reveals how NB-IoT is being designed and how it can be deployed in GSM spectrum, within an LTE carrier, or in an LTE or WCDMA guard band.

A presentation made at A 2-day Annual Symposium, organized by Electrical/Electronic Engineering Department, FUTO, at School of Engineering and Engineering Technology (SEET) Complex Auditorium, FUTO, Imo State. (August 18, 2016)
Interesting Whitepaper from #HCLTECH, though a bit old (2016) but good for beginners on 5G and introductory know-how about 5G start with IMT2020. Informative insights.
Currently, there is a hype around 5G, the wireless technology which is meant to deliver higher multi-Gbps peak data speeds, more reliability, massive network capacity, and increased availability, in order to empower new experiences and connect new industries. Indeed 5G, and related technology, open up an industrial Internet with the potential to deliver new digital services for long-term economic growth.
The following document is written as a summary of essentials around 5G based on already published materials. It aims at helping non-specialists to get an initial idea of the new exciting technologies and their potential impact on our future.
LTE mobile technology has changed our lifestyles significantly with high data rates and low latency. With the
diverse services and requirements demanded from today's mobile industry, however, LTE by itself is not capable
of handling the necessary throughput, latency and reliability. Compared to LTE, 5G enables much higher data
rates and ultra-low latency by using wide spectrum of high-frequency bands and advanced networking
technology. 5G targets twenty times higher data rates and much shorter latency than LTE. As a result, more
reliable transmissions and higher UE connection density will be possible in the 5G network.

Leading the LTE IoT evolution to connect the massive Internet of ThingsQualcomm Research
Connecting the IoT—and virtually everything—requires wireless technologies that can scale up to high-performance IoT but also scale down to low complexity IoT application needs. LTE with its global footprint and scale will play a key role in connecting the IoT, and continues to evolve to also address the massive, wide-area, low-power, low-complexity IoT applications. In 3GPP Release 13, two complementary narrowband technologies – eMTC & NB-IoT – were introduced to reduce complexity, lower power consumption, deepen coverage, and increase user density. In 2017, commercial LTE IoT is starting to connect the massive IoT, and it will become an essential part of the 5G Platform, which initially focuses on enhanced mobile broadband. Its rich roadmap will further enhance efficiencies, bring new capabilities, and expand into unlicensed spectrum to meet tomorrow’s massive IoT needs.

This report describes the 5G requirements, use cases and technologies which are modelling the transformation of the core network and a roadmap how the 3GPP Evolve Packet Core can be modified to become the core for the 5G networks.
4G LTE over satellite is arriving to the market at a faster pace than 2G and 3G did when they emerged. 4G carries the promise of a true mobile broadband experience with high volumes, higher speeds and enhanced efficiency, blurring the lines between cellular and wifi. Mobile operators will nevertheless wonder if 4G can be even more successful than its predecessors, and what value it really brings to the subscriber. They will also want to know if there are specifi c characteristics required to run the service over satellite, and if it is possible to optimize the traffi c just like in 2G and 3G to gain bandwidth and decrease the OPEX. Lastly, can 4G deployments be future proof in light of the upcoming 5G standards?

The growing interest in cloud computing scenarios that incorporate both distributed computing capabilities and heterogeneous hardware presents a significant opportunity for network operators. With a vast distributed system (the telco network) already in place, the telecom industry has a significant advantage in the transition toward distributed cloud computing.
This Ericsson Technology Review article explores the future of cloud computing from the perspective of network operators, examining how they can best manage the complexity of future cloud deployments and overcome the technical challenges. Redefining cloud to expose and optimize the use of heterogeneous resources is not straightforward, but we are confident that our use cases and proof points validate our approach and will gain traction both in the telecommunications community and beyond.
Ericsson Technology Review: Optimizing UICC modules for IoT applicationsEricsson
Commonly referred to as SIM cards, the universal integrated circuit cards (UICCs) used in all cellular devices today are in fact complex and powerful minicomputers capable of much more than most Internet of Things (IoT) applications require. Until a simpler and less costly alternative becomes available, action must be taken to ensure that the relatively high price of UICC modules does not hamper IoT growth.
This Ericsson Technology Review article presents two mid-term approaches. The first is to make use of techniques that reduce the complexity of using UICCs in IoT applications, while the second is to use the UICCs’ excess capacity for additional value generation. Those who wish to exploit the potential of the UICCs to better support IoT applications have the opportunity to use them as cryptographic storage, to run higher-layer protocol stacks and/or as supervisory entities, for example.
Ericsson Technology Review: 5G BSS: Evolving BSS to fit the 5G economyEricsson
The 5G network evolution has opened up an abundance of new business opportunities for communication service providers (CSPs) in verticals such as industrial automation, security, health care and automotive. In order to successfully capitalize on them, CSPs must have business support systems (BSS) that are evolved to manage complex value chains and support new business models. Optimized information models and a high degree of automation are required to handle huge numbers of devices through open interfaces.
This Ericsson Technology Review article explains how 5G-evolved BSS can help CSPs transform themselves from traditional network developers to service enablers for 5G and the Internet of Things, and ultimately to service creators with the ability to collaborate beyond telecoms and establish lucrative digital value systems.
Ericsson Technology Review: 5G migration strategy from EPS to 5G systemEricsson
For many operators, the introduction of the 5G System (5GS) to provide wide-area services in existing Evolved Packet System (EPS) deployments is a necessary step toward creating a full-service, future-proof 5GS in the longer term. The creation of a combined 4G-5G network requires careful planning and a holistic strategy, as the introduction of 5GS has significant impacts across all network domains, including the RAN, packet core, user data and policies, and services, as well as affecting devices and backend systems.
This Ericsson Technology Review article provides an overview of all the aspects that operators need to consider when putting together a robust EPS-to-5GS migration strategy and provides guidance about how they can adapt the transition to address their particular needs per domain.
Ericsson Technology Review: Creating the next-generation edge-cloud ecosystemEricsson
The surge in data volume that will come from the massive number of devices enabled by 5G has made edge computing more important than ever before. Beyond its abilities to reduce network traffic and improve user experience, edge computing will also play a critical role in enabling use cases for ultra-reliable low-latency communication in industrial manufacturing and a variety of other sectors.
This Ericsson Technology Review article explores the topic of how to deliver distributed edge computing solutions that can host different kinds of platforms and applications and provide a high level of flexibility for application developers. Rather than building a new application ecosystem and platform, we strongly recommend reusing industrialized and proven capabilities, utilizing the momentum created with Cloud Native Computing Foundation, and ensuring backward compatibility.
Ericsson Technology Review: Spotlight on the Internet of ThingsEricsson
The Internet of Things (IoT) has emerged as a fundamental cornerstone in the digitalization of both industry and society as a whole. It represents a huge opportunity not only in economic terms, but also from a global challenges perspective – making it easier for governments, non-governmental organizations and the private sector to address pressing food, energy, water and climate related issues.
5G and the IoT are closely intertwined. One of the biggest innovations within 5G is support for the IoT in all its forms, both by addressing mission criticality as well as making it possible to connect low-cost, long-battery-life sensors.
With this in mind, we decided to create a special issue of Ericsson Technology Review solely focused on IoT opportunities and challenges. I hope it provides you with valuable insights about the IoT-related opportunities available to your organization, along with ideas about how we can overcome the challenges ahead.
This presentation explains the importance of SD-WAN technology as part of the Enterprise digital transformation strategy. It goes over the first wave of SD-WAN in a single vendor deployment, with Do-it-yourself (DIY) as the preferred model. Then continues with the importance of orchestration in the second wave of SD-WAN deployments in a multi-vendor ecosystem, turning to SD-WAN Managed Services as the preferred model. It ends up with some examples of use cases and the Verizon customer case. More information on Ericsson Dynamic orchestration - http://m.eric.sn/6rsZ30psKLu

Ericsson Technology Review: Key technology choices for optimal massive IoT de...Ericsson
The massive IoT device domain faces two key challenges: cost-efficiently connecting a large number of devices in a wide area, and efficiently managing these devices over their complete life cycle. Further, since security and trust are key requirements in most massive IoT applications, it is important to ensure that the devices are secure, both in terms of communication and data integrity end-to-end (E2E), from device to data usage.
The latest Ericsson Technology Review article explores how to address these challenges in five key technology areas – connectivity, communication protocols, security, identity solutions and machine intelligence (MI). Carefully considered choices in these areas make it possible to achieve the desired key device characteristics and create IoT devices that support the multitude of existing and emerging massive IoT use cases.
Ericsson Technology Review: The advantages of combining 5G NR with LTEEricsson
Capacity exhaustion is a growing challenge for network operators due to the rapidly increasing data consumption by mobile broadband (MBB) subscribers. Rather than addressing this by densifying 4G networks with new sites, 5G New Radio (NR) offers operators the opportunity to meet growing demand and improve performance through the efficient use of new frequency bands at existing sites. The latest Ericsson Technology Review article explains how deploying 5G NR with mid bands (3-6GHz) at existing 4G sites enables maximal reuse of site infrastructure investments as well as delivering a significant performance boost. By adding NR with 100MHz unpaired spectrum, it is possible to achieve eight times higher downlink capacity relative to LTE (2x50MHz paired spectrum). Massive MIMO techniques, such as beamforming and multi-user MIMO, deliver improved downlink data rates both outdoors and indoors.

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

"Impact of front-end architecture on development cost", Viktor TurskyiFwdays
I have heard many times that architecture is not important for the front-end. Also, many times I have seen how developers implement features on the front-end just following the standard rules for a framework and think that this is enough to successfully launch the project, and then the project fails. How to prevent this and what approach to choose? I have launched dozens of complex projects and during the talk we will analyze which approaches have worked for me and which have not.

BY REDUCING ARCHITECTURE OPTIONS
Simplifyingthe
Previous mobile generations have taught us that industry efforts to reduce
fragmentation yield massive benefits. In the case of 5G, an industry effort
to focus deployment on a limited set of key connectivity options will be
critical to bringing it to market in a timely and cost-efficient way.
TORBJÖRN CAGENIUS,
ANDERS RYDE,
JARI VIKBERG,
PER WILLARS
The multiple connectivity options in the 3GPP
architecture for 5G have created several
possible deployment alternatives. Initial
deploymentsfocusonoptions3(non-standalone
New Radio) and 2 (standalone New Radio).
However, the deployment of several
additional options would create a level of
complexity that impacts the whole 5G
ecosystem – across operator network
operations, equipment vendors and user
equipment (UE) chipset vendors as well as
spectrum assets. To avoid ecosystem
fragmentation, we believe that the best
approach is to limit the number of options
that are deployed.

Key enablers
❭❭ LTE-NR spectrum sharing
3GPP specifications allow efficient sharing of operator spectrum, so that one carrier appears as an NR carrier
to NR UEs, and an LTE carrier to LTE UEs. Resources are pooled and distributed dynamically between the two
RATs, according to instant needs. There is no impact on legacy LTE UEs, and the impact on LTE capacity is very
small. Compared with classic refarming, this provides a smooth migration of spectrum from LTE to NR as
NR-capable UE penetration increases, enabling NR to be rolled out on new and legacy bands.
❭❭ Spectrum regulation
Spectrum is becoming technology neutral in most of the world except for a few markets and frequency bands
where the spectrum license is currently tied to a specific RAT, prohibiting NR to operate in existing frequency
bands.ItisimportantthatregulatorsacknowledgetheneedforNRdeploymentinallbands.Thisisakeyenabler
