5 g latin america april 2019 network densification requirements v1.0Alberto Boaventura
Brings the discussion about the challenges about how network densificiation addresses 5G high density traffic and related challegens. Discusses about: interefence mitigation; synchronism and latency management; high capilarity optical transport challenges; network optimization challenges and AI bennefits; importance of public policy and others.
The Next Generation Mobile Networks Alliance feels that 5G should be rolled out by 2020 to meet business and consumer demands. In addition to providing simply faster speeds, they predict that 5G networks also will need to meet new use cases such as the Internet of Things (internet connected devices) as well as broadcast-like services and lifeline communication in times of natural disaster. Although updated standards that define capabilities beyond those defined in the current 4G standards are under consideration, those new capabilities have been grouped under the current ITU-T 4G standards. The U.S. Federal Communications Commission (FCC) approved the spectrum for 5G, including the 28 Gigahertz, 37 GHz and 39 GHz bands, on July 14, 2016. 5G research and development also aims at improved support of machine to machine communication, also known as the Internet of things, aiming at lower cost, lower battery consumption and lower latency than 4G equipment. To put it simply, the use cases for 4G networks has expanded well beyond the initial scope of the standard. 5G is what you get when you reset the standard/design to cope with the increase in scope.4G networks don’t just support mobile devices anymore. IOT (Internet of Things) devices are everywhere and the number of them is only going to increase. We’re seeing 4G modems in smart watches, in CCTVs and even in doorbells.

Ericsson Technology Review – Microwave backhaul gets a boost with multibandEricsson
With the exception of Northeast Asia, 65 percent of all cell sites will be connected to the rest of the network using microwave backhaul technology by 2020. Between now and then, the performance of microwave backhaul will continue to improve, supporting growing capacity needs through technology evolution and more efficient use of spectrum. So as the dominant backhaul media in modern networks, the ability of microwave to carry traffic plays a significant role in providing good mobile network performance.
Technology evolution, increased mobility, and massive digitalization continue to place ever more demanding performance requirements on networks. The constant pressure to increase performance translates into a need for more spectrum, and more efficient use of it – not just when it comes to radio access, but for microwave backhaul as well.
But spectrum is a finite natural resource, so technology developments not only need to be able to make use of higher frequencies, they also need to unleash the potential of all the untapped spectrum that exists.
Radio-link bonding is a well-established method for enhancing peak capacity, enabling multiple radio carriers to be aggregated into a single virtual one. So far, developments have focused on bonding carriers within the same frequency band. The multiband booster concept, however, uses radio-link bonding to aggregate carriers in different frequency bands, enabling the full spectrum potential to be unleashed.
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.

Visual Perception 101: Designing Better User Interfaces by Calvin Arterberry Calvin Arterberry, MA
Learn how to design better user experiences and user interfaces with this introductory presentation on the fundamentals of Visual Perception and cognitive psychology.
Vision is our most developed sense and one upon which we rely to make many decisions, conscious or otherwise. Many of our everyday interactions, such as driving a car, greeting familiar faces on the street, or deciding which dish to order at a restaurant, are guided by our visual sense. For the most part, this works well. But sometimes we are reminded of our visual system’s limitations and surprising behavior through optical illusions that exploit misjudgments in size, distance, depth, color and brightness, among many others. This lecture presents and explains a diverse collection of visual perception phenomena that challenge our common knowledge of how well we detect, recognize, compare, measure, interpret, and make decisions upon the information that arrives at our brain through our eyes. It also explains the relationships between the latest developments in human vision research and emerging technologies, such as: self-driving cars, face recognition and other forms of biometrics, and virtual reality. After seeing a large number of examples of optical illusions and other visual phenomena, this talk will make you wonder: can you really trust what you see?

PHP Frameworks: I want to break free (IPC Berlin 2024)Ralf Eggert
In this presentation, we examine the challenges and limitations of relying too heavily on PHP frameworks in web development. We discuss the history of PHP and its frameworks to understand how this dependence has evolved. The focus will be on providing concrete tips and strategies to reduce reliance on these frameworks, based on real-world examples and practical considerations. The goal is to equip developers with the skills and knowledge to create more flexible and future-proof web applications. We'll explore the importance of maintaining autonomy in a rapidly changing tech landscape and how to make informed decisions in PHP development.
This talk is aimed at encouraging a more independent approach to using PHP frameworks, moving towards a more flexible and future-proof approach to PHP development.
zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Removing Uninteresting Bytes in Software FuzzingAftab Hussain
Imagine a world where software fuzzing, the process of mutating bytes in test seeds to uncover hidden and erroneous program behaviors, becomes faster and more effective. A lot depends on the initial seeds, which can significantly dictate the trajectory of a fuzzing campaign, particularly in terms of how long it takes to uncover interesting behaviour in your code. We introduce DIAR, a technique designed to speedup fuzzing campaigns by pinpointing and eliminating those uninteresting bytes in the seeds. Picture this: instead of wasting valuable resources on meaningless mutations in large, bloated seeds, DIAR removes the unnecessary bytes, streamlining the entire process.
In this work, we equipped AFL, a popular fuzzer, with DIAR and examined two critical Linux libraries -- Libxml's xmllint, a tool for parsing xml documents, and Binutil's readelf, an essential debugging and security analysis command-line tool used to display detailed information about ELF (Executable and Linkable Format). Our preliminary results show that AFL+DIAR does not only discover new paths more quickly but also achieves higher coverage overall. This work thus showcases how starting with lean and optimized seeds can lead to faster, more comprehensive fuzzing campaigns -- and DIAR helps you find such seeds.

A tale of scale & speed: How the US Navy is enabling software delivery from l...sonjaschweigert1
Rapid and secure feature delivery is a goal across every application team and every branch of the DoD. The Navy’s DevSecOps platform, Party Barge, has achieved:
- Reduction in onboarding time from 5 weeks to 1 day
- Improved developer experience and productivity through actionable findings and reduction of false positives
- Maintenance of superior security standards and inherent policy enforcement with Authorization to Operate (ATO)
Development teams can ship efficiently and ensure applications are cyber ready for Navy Authorizing Officials (AOs). In this webinar, Sigma Defense and Anchore will give attendees a look behind the scenes and demo secure pipeline automation and security artifacts that speed up application ATO and time to production.
We will cover:
- How to remove silos in DevSecOps
- How to build efficient development pipeline roles and component templates
- How to deliver security artifacts that matter for ATO’s (SBOMs, vulnerability reports, and policy evidence)
- How to streamline operations with automated policy checks on container images

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).

Climate Impact of Software Testing at Nordic Testing DaysKari Kakkonen
My slides at Nordic Testing Days 6.6.2024
Climate impact / sustainability of software testing discussed on the talk. ICT and testing must carry their part of global responsibility to help with the climat warming. We can minimize the carbon footprint but we can also have a carbon handprint, a positive impact on the climate. Quality characteristics can be added with sustainability, and then measured continuously. Test environments can be used less, and in smaller scale and on demand. Test techniques can be used in optimizing or minimizing number of tests. Test automation can be used to speed up testing.

Editor's Notes
Very often, it is claimed – especially from Femtocell equipment vendors – that Femtos enable ‘huge savings” in the macro network and only by this make the business case! So, we decided to take a closer look! Please mind: The DFP data demand (Kim Larsen) has been used as input. Further we used the Network Economic RAN and Femto cost model for this calculation. Please also mind that this is a strategic analysis, i.e. that the modelled cost increase due to traffic demand is not aligned with local budgets (click)
We assume that only those “heavy users” will get a Femto. (Please mind that this is an important assumption. As in reality not every heavy user is likely to accept a Femto – he may not like the concept or does not have the necessary broadband subscription– our cost saving calculations should be regarded as an upper limit ! Now we know the number of Femtos, which need to be deployed in each year. We look into the Femto cost model (click – Femto TCO curve is blinking) and get the cost of Femto deployment for each year. As even with a deployment of Femtocells, the traffic in the macro network will continue to grow, we again have to look in RAN model and calulate the increase in TCO of the Macro network compared to the base year, this time however including the offload effect of Femtos. (click – Macro TCO curve - incl. Femto – is blinking) The upgrade costs of the Macro network which occur despite Femto deployment have to be added on top of the costs of the femto deployment itself. These total costs incurred by Femtos can now be compared to the costs without Femtos (thus the Macro upgrade costs stand alone) So - (click: animation starts – bottom graph appears)
