Intends to analyze the challenges for low latency services and upcoming new data opportunities. Describes the Internet data service waves: Internet Mobile; Internet of Things and now Tactile Internet, how low latency is becoming the king and new data services, the main attribute. Tactile Internet will open immersive services experience beyond current audiovisual ones, but it depends to understand the human sense reaction idiosyncrasies. Also for IoT, how latency will affect overall productive processes since new robotics control for Industry 4.0 to remote surgery. It introduces the Edge Computing as one the most important toll to reduce latency by facilitating data processing at or near the source of data generation. I.e., Edge Computing avoids the application data travels from the source to very far application and processing hosts. But the latency reduction does not have an unique strategy, and it requires to have transport network proper dimensioned and configured can certainly improve the network low latency. In addition, new transport architecture with simplification collapsing network layers, network aware multidomain control, automation etc. will be definitively imperative for optimizing latency for new critical applications. Improving processor performance using technologies beyond regular x86 servers, such as: GPUs, FPGA, DPDK etc, can reduce the time of workloads and delivering/returning data to user application with readiness.
In terms of low latency opportunities, accordingly to Chatan Sharma Consulting, Edge Internet economy will be over $4.1 Trillion worldwide. The initial growth will come from Edge serving existing use cases and will gradually be accelerated by the new use cases as the deployment becomes more widespread and developers learn to take advantage of the Edge Internet architecture for applications across industry domains in all major markets. But for MNOs, Edge Computing will open a several opportunities such as Service Integration, Managed Services, IaaS/PaaS/SaaS, new collocation business modelling etc. Besides latency, in general Edge Computing can bring an immediate benefit around local traffic offloading that implies in reducing overall CapEx cost. Higher Traffic Density can rapidly justify the Edge Computing deployment.

Mobile Network Operators need to continuously expand capacity to meet the rapid growth in mobile data consumption. Crucially, this extra capacity needs to be delivered where demand arises, including deep indoors and in areas that are covered by fewer mobile radio sites. While substantial amounts of mid-bands spectrum and high-band spectrum are becoming available, the gap in the amount between low-band (sub-1 GHz) and mid-bands is increasing.
It was a great pleasure having this presentation presented at the Tehran 5G Conference in Iran this October, 2016. It kick started my thinking & analysis of the economics of 5G, While 5G have many great technology promises, a lot have to happen with our business models and economics to also cash in on those promises. Enjoy this presentation and stay tuned for many more on this important topic.

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.

The more people have been able to achieve while on the move, the more dependent society has become on mobile broadband networks. As applications like self-driving vehicles and remotely operated machinery evolve, become more innovative, and more widespread, the level of performance that 5G networks need to deliver will inevitably rise. Keeping pace with ever-increasing demand calls for greater flexibility in all parts of the network, which in turn requires tight integration between 5G radio, transport networks, and cloud infrastructures.

Founded in 2006, the HetNet Forum is the only national network of leaders focused on shaping the future of heterogeneous wireless networks (the HetNet). The HetNet is a wireless ecosystem, comprised of a variety of mobile and wireless technologies and infrastructure, interoperable with the macro-cellular network providing harmonious voice and data communications.
Cellular networks have facilitated positioning in addition to voice or data communications from the beginning, since 2G, and we’ve since grown to rely on positioning technology to make our lives safer, simpler, more productive, and even fun. Cellular positioning complements other technologies to operate indoors and outdoors, including dense urban environments where tall buildings interfere with satellite positioning. It works whether we’re standing still, walking, or in a moving vehicle. With 5G, cellular positioning breaks new ground to bring robust precise positioning indoors and outdoors, to meet even the most demanding Industry 4.0 needs.
As we look to the future, the Connected Intelligent Edge will bring a new dimension of positional insight to a broad range of devices, improving wireless use cases still under development. We’re already charting the course to 5G Advanced and beyond by working on the evolution of cellular positioning technology to include RF sensing for situational awareness.

Ericsson Technology Review: Meeting 5G latency requirements with inactive stateEricsson
Low latency communication and minimal battery consumption are key requirements of many 5G and IoT use cases, including smart transport and critical control of remote devices. Thanks to Ericsson’s 4G/5G research activities and lessons learned from legacy networks, we have identified solutions that address both of these requirements by reducing the amount of signaling required during state transitions, and shared our discoveries with the 3GPP.
This Ericsson Technology Review article explains the why and how behind the new Radio Resource Control (RRC) state model in the standalone version of the 5G New Radio standard, which features a new, Ericsson-developed state called inactive. On top of overcoming latency and battery consumption challenges, the new state also increases overall system capacity by decreasing the processing effort in the network.
This presentation summarizes the many technology ideas and business models to achieve Ultra-efficient network operation while safeguarding customer quality and expectations. This work was presented at Informa's Broadband MEA conference in Dubai, 26th of Match 2012.

Encryption in Microsoft 365 - ExpertsLive Netherlands 2024Albert Hoitingh
In this session I delve into the encryption technology used in Microsoft 365 and Microsoft Purview. Including the concepts of Customer Key and Double Key Encryption.
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.

Combination of huge number of Smallcells with fiber premises for connectivity
will bring an important concern for 5G infrastructure.
CRAN requires a tighter latency requirement for
interefrence control (e-ICIC and CoMP) - In general IP
backhaul transport cannot accomplish this latency level
in X2 interface.
CRAN unfolds complexity of capillarity for access
trasportation;
mmWave has a benefit to provide a very high capacity
but a short range coverage. Thus, multiplying the
number of Smallcells .
9. TCO Optimization & Reduction
● Simplification of IP hierarchies by providing a more "flat" network;
● Integrated planning of IP and Transmission networks;
● Service virtualization, network optimization, and on-demand allocation;
● Time-to-market agility;
● Programmability, service automation and speed of provisioning;
● Reduction of Network Costs (CAPEX and OPEX), with the reduction of the number of routers, spare-
parts, support contract, management license etc.
● Data Plane Control Plane Separation, vendor-independent unified control;
● Reduction of Engineering sites, main sites in the SDN-NFV model, Telco-Datacenters;
● Integration of IP core and TX (OTN + DWDM), full-mesh core (minimize latency and router interfaces),
SDN-WAN multilayer;
Typical Multilayer
Node
● Superchannel DWDM (400G / 1T) in the short and
medium term, single-carriers grouped with more
spectral efficiency.
● Same modulation of 100G, optimizes costs and
covers the same distance (span).

11. Lifecycle Management
Optimization of Total Costs:
Voice: 2G => 3G and Data: 3G => 4G bring significant savings in terms of total network costs;
Service balancing should take into account not only the network cost but the best use of an expensive
and scarce resource: spectrum;
Phaseout Management:
Today the mobile network has 3 access technologies (2G / 3G / 4G) that need to be realized:
management, planning, deployment, O & M, etc. multiplying operating costs (OpEx) and investments
(CapEx);
Some operators have already announced the end of either the 2G network or the 3G network aiming not
only to simplify and reduce operating costs, but also to re-use spectrum;
User Experience:
Churn is still the biggest challenge for operators, mainly due to the costs associated with acquiring new
users in a consolidated market.
The negative perception of services due to poor user experience is the main reason for the cancellation
and / or change of service provider.
Asset Management:
Technology evolution takes better advantage of features and brings a general improvement in overall
user experience. It also optimizes long-term investments and spectrum.
Technology and life cycle management is not simple, but it is one of the most important tools for
network strategic planning and even for tactical and operational planning.

13. Digital Transformation in Telecommunication Industry
Source: World Economic Forum 2017 : Digital Transformation Initiative Telecommunications Industry
Digital transformation in telecommunications could unlock more than $2 trillion in
value for the industry, consumers and wider society over the next decade.
● Accordingly with WEF 2017, SDN & NFV plays the central
role of Digital Transformation of Operator Network
● These technologies promise several important benefits: SDN
by separating the control and data layers; and NFV by
replacing complex network functions with easy-to-
manipulate virtualized software.
● Widespread adoption of these technologies will be driven
primarily by network cost reduction – 64% of operators
rated this as the main adoption trigger in a recent survey.
● It is estimated that SDN and NFV could generate savings of
25% to 75% of overall operator operating expenditure
thanks to significantly reduced provisioning, monitoring and
hardware costs.
● These technologies also promise to create value for
customers through flexible services, faster times to market
and improved user experiences.
● The ability to view and manipulate network functions on
demand, and at a granular level, will catalyse service
innovation and allow stronger collaborations between
customers and providers.
