Säkerhetshot och lösningar för privatpersoner med bredband

As more and more people gain access to Broadband in their properties, the security threats get bigger. A lot more people also have computers that they carry home from work where they store important information concerning the company. The information stored on theese computers can be very easy to retrieve if you have the will and the skill to do it. Very few people have any knowledge how to protect themselves from theese threats..

Framgångsfaktorer på bredbandsmarknaden ? vad utmärker en framgångsrik marknad?

This master thesis is written at the Royal Institute of Technology during the spring and summer of 2008.The assignment was to investigate what factors on a Broadband market determine how well it performsin terms of how many people have access to Broadband. These are the factors that determine whetheror not a country or market will be able to achieve a high Broadband penetration. The purpose of thisthesis was to establish a better understanding for what a market should look like or how a strugglingone can be complemented in order to succeed.As a foundation for this investigation, a group of benchmark countries were chosen and evaluated. Inaddition to this, a group of, developing MENA2-countries were chosen and evaluated. Finally, interviewswere performed with some of Sweden?s leading internet service providers, the regulatory agency andinfrastructure company, Skanova.Among the benchmark countries were Sweden, France, Canada, South Korea and Japan.

The increased degree of specialization means that these players need to cooperate with each other in different types of projects.Problem definition: What factors are important in a project to achieve the objectives as quickly as possible? More players should lead to cooperation difficulties, how can you coordinate in the best possible way? Today, it is desirable for all parties in the project to shorten down the lead time.Purpose: The main purpose is to explore the different factors that affects the project's lead time concerning Broadband installation. The part purpose, is to analyze and assess the conditions for cooperation between different players in the project for Broadband installation and to provide a recommendation.Method: In order to answer the problem definition, the paper is structured around a qualitative approach with interviews to obtain data. Mostly, the used data comes from primary sources with an extension of secondary sources.Theories: Theories that are used in the paper are: Communication Process, Communication Plan, Project Planning & Project Plan, Efficiency through collaboration, Communication in a network.Empiric: Empirical data consists of primary data collected through interviews.Analysis: The analysis is based on the variables from the theoretical frame of reference; Communications, Planning, Interaction & Information.

Förutsättning och fördelar att införa kvalitetsledningssystem enligt ISO 9001

The ISO 9000-series is a set of quality standards created by the International Organization for Standardization. The series is intended to provide guidance to companies in the process of deploying an effective quality management system. The series includes the requirements standard ISO 9001. This standard contains requirements on how a quality management system should be designed and how companies generally must work with quality issues. When a quality management system is introduced, if wanted, a quality certification can be implemented.

En branschanalys av den svenska mobilmarknaden -Strategi, konkurrenssituationen och 4G:s påverkan

Background and problemThe Swedish mobile market is highly competitive despite the oligopoly that currently exists. A short product life cycle together with fads and new innovations puts pressure on the operators to respond to the ever changing environment and to develop and adapt their strategies after it.As a previous study regarding a specific operator?s strategy was cancelled due to the extensive confidentiality surrounding it, an interest was sparked to perform an industry analysis as this is clearly something the actors spend a great deal of time on developing. The launch of the 4G network will offer new opportunities for the operators regarding products services. It may also impact the competition on the overall market.PurposeThe purpose of this thesis is to present a deep analysis of the industry and give the reader a comprehensive picture of existing conditions.

Verktyg för mätning av tjänstekvalitet på bredbandsnät

Operators and Internet service providers invest in Broadband to be able to deliver new services that require higher data transmission rate. A way to make this possible is to use ADSL, Asymmetric Digital Subscriber Line, as the access technology. To be able to handle this technology, the service providers should do a pre-qualification. Methods and tools are needed to analyze the local copper lines and decide if these qualify for ADSL with respect to service availability and possible bandwidth through the lines. This report brings up some methods for pre-qualification of ADSL, the important quality parameters and how to gather them from the available services today.

Undersökning av modulationsscheman för existerande bredbandsteknologier

In this thesis some different modulation schemes for xDSL-techniques are compared. The investigated techniques are ADSL, G.lite, ADSL2, HDSL, SHDSL and VDSL. The modulation methods used are DMT, CAP and different versions of PAM. Several Broadband techniques also use Trellis Coded Modulation (TCM) to increase the coding gain of the transmission. For each one of the different modulation methods the signal-to-noise ratio is calculated for generating a bit error rate probability of 10-7.

Användbara mobila reseplanerare

Enligt kommunikationsmyndigheten PTS finns det cirka 10miljoner mobiltelefonabonnemang endast i Sverige. Telefonerna innehåller operativsystem där det tillåts mängder av olika sorters program. I och med att Apple 2007 introducerade sin iPhone exploderade marknaden för så kallade Nomadic Devices. En telefon som mer är tänkt att fungera som någon form av handdator. Dessa telefoners utformning och funktioner möjliggör för utvecklare att ta fram mer avancerade program än man tidigare sett för mobiltelefoner.

Radomoptimering för luftburna störsändarkapslar

These studies are done in behalf of Saab AB AVITRONICS in Järfälla in the form of a thesis atthe Royal Institute of Technology in Stockholm.The task was to examine the parameters that plays a role in the construction of modern radomesoperating in Broadband applications.This was interesting for Saab to get an indication of which way they should go at the newdevelopment of radomes for the next generation of equipment for electronic warfare.After a thorough analysis of the influencing parameters, a optimization application was made toget a automated way to get a radome design by specifying data on the radome size, airloads,materials, etc.This is to minimise the time of the laborious work that radome development.inply.This was solved by letting ANSYS calculate the strength of the radome structure and MATLABcalculate electromagnetic data and cost models of different sizes and materials.All these parameters woven together with the optimization tool modeFrontier picks data from therespective program and perform an optimization algorithm and then iterate a step and sends thisdata to calculation programs for the new input data. In the end, we have received a convergedpoint with our optimal solution.For the presumptions and limitations for which applied for this thesis, the result was prettyintuitive. That is to say that the smaller radome - the less materal is needed and lowermanufacturing costs results in the cheapest solution possible. The reality is not so simple. Whereyou have to take more of the electrical details such as the effect on the transmitter as a majorfactor..

En ny musikarena utan solister

The music industry has been subject to great changes during the last ten years. The most significant factor contributing to this change is the increasing usage of Broadband and thereby the increasing frequency of downloading music illegally. Music piracy and file sharing have caused record sales to plummet. Consumers have now moved on to consuming music in a digital format, not only through downloading but also from streaming music online, an activity partly made possible by social media channels such as YouTube. As the consumption patterns have changed companies within the music industry have been forced to find other sources of income than record sales and they have also needed to find alternate ways to market their artists.
