    Exploring the ICT market with learning´s from a leading market: With an internationalization perspective2015Independent thesis Basic level (university diploma), 10 poäng / 15 hpOppgave
    Abstract [en]

    Purpose - The purpose of the thesis is “To explore the Thai ICT market and identify

    differences with the leading market” Where the research questions are:

    1. How are the main actors influencing the ICT market in Thailand?

    2. How can the ICT market in Thailand be improved by identifying the gaps to

    the leading market?

    Method – For reaching the purpose a qualitative case study has been carried out,

    methods that are used are interviews, observations, document studies and literature

    study. Secondary data has been collected from document studies and was compiled in

    excel documents. Primary data has been collected from interviews, employees at

    Ericsson in Thailand has contributed when gather data about organizational

    culture. Interview with representatives from institutions in Thailand were made to

    achieve current data. Interviews were made to receive a primary source of information

    with high focus on the thesis subject and strengthen by secondary data.

    Findings – The most urgent problem to improve the ICT market in Thailand is to

    develop the infrastructure. The infrastructure needs to be developed in rural areas and

    urban areas. Institutions in ICT need to do active work on the market in order to

    expand and develop the market. Service operator’s needs to standardise and offer less

    price plans in order to minimize confusion among the consumers. The consumers

    need to increase their usage of ICT services in order to decrease the gap to the leading

    ICT market. One solution could be that the government push the development with all

    actors on the ICT market. Changing the foreign business act can lead to investments

    needed to expand the infrastructure. Further, creating a demand of higher technology

    from the consumer’s perspective will pressure the actors to develop robust network of

    high technology and benefit future development of technology.

    Implications – This study has been carried out on location in Thailand but

    communication has not been made in the national language in Thailand, which can

    contribute to misunderstandings of data. The study´s result is strengthened by being

    on location in Thailand, gathering primary data by interviews and do observations on

    place in the target environment.

    Delimitations – The delimitations have been made to look at the ICT market from

    Thailand’s perspective with learning’s from Sweden. Further, delimitations to explore

    the main actors that are influencing the market has been done. A market has many

    environmental forces and they needed to be restricted in this study.

    Telepreneurship: Strategic bliss2010Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    The strategic management literature indirectly considers entrepreneurship as a subset of strategy, and the historical evolution of the field, specifically that of the Entrepreneurship division of the Academy of Management. Schendel (1990) which placed great emphasis on the topic of entrepreneurship and admitted that some argue that entrepreneurship is at the very heart of strategic management. This thesis explores the strategic use of entrepreneurship in the telecommunication industry.

    Through the use of strategic entrepreneurship theories both from the strategy and entrepreneurial fields provide the thesis with a foundation to explore and extract empirical results from two case samples known as Vox telecom and Telkom limited. Through an Interpretivist research design which includes thirty interviews in three different phases resulted in the empirical primary data for analysis. The research approach was carried out through an adaptive GT (Grounded Theory) technique which allowed the thesis to capture industry and organisational specific behaviours. The adaptive GT resulted in open, axial and selective coding which finally represented three themed domains. The domains include: the environmental, innovation and corporate orientation domain.

    The adaptive GT results were conducted through eighteen steps which finally represented three cycles. Chapter 6 represent the first cycle, which demonstrate the analysis and result of the primary data which was gathered during the 1st interview phase, mostly collecting entrepreneurial management practises while the 2nd interview phase represent the strategic organisational empirical findings. The result mainly describes the telecom industry through the scope of the two organisations in our sample, namely Telkom and Vox telecom in South Africa.

    The second cycle demonstrates the analysis and results which ultimately described the thesis knowledge contribution. The result is displayed and demonstrated in Chapter7 as the Telepreneur framework. The Telepreneur framework includes three models, namely the Telenetwork, Technovation and Telepreneurship model.

    Finally, in Chapter8 we attempt to test the formulated Telepreneur framework. This chapter represent the third cycle in which describes the result and analysis of the tested Telepreneur framework. The testing is conducted through evaluating the Telepreneur framework in the telecom industry through the third interview phase. The testing processes use two sets of survey data therefore quantitatively testing the result against specified industry data to further generalize the Telepreneur frame. In the end the outcome demonstrated a positive correlation regards the suggested formulated findings grounded in theory verses the empirical testing of the two sample cases and secondary survey data.

    A comparison of energy usage between LoRa 433Mhz and LoRa 868MHz2021Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    The number of devices connected to the internet is constantly increasing and therefore putting more weight on the importance of low energy usage. LoRa which is the physical part of the LoRaWAN communication protocol that this paper focuses on is popular in the area of IoT because of its low energy usage. The purpose of this paper was to find out how the energy usage differentiate between two of the most commonly used LoRa frequencies 433MHz and 868MHz.

    LoRa is often used with battery driven components within IoT such as temperature or humidity sensors. It is of great importance to keep the maintenance cost for these devices to a minimum. And it is therefore important to find the most energy efficient solutions for communication between LoRa components.

    To get an answer from the purpose of this paper, two questions were formulated, and they were in turn answered by using an experimental research method. For the experiment, two devices were set up using: one transmitter combined with a current sensor and one receiver, both of which were capable of using either LoRa 433MHz or 868MHz. The experiment was then conducted by transmitting 1000 packages for every DR and both of the frequencies.

    The results were analysed in an empirical quantitative way which showed that the higher frequency of 868MHz consumed more energy in all of the experiments. One discovery that was quite interesting was that the difference could be mitigated by using different data rates.

    The result in this paper is intended to increase the knowledge regarding LoRa and its energy usage. This papers result can be used as a reference when choosing between what frequency and data rate to use when working with LoRa.

    ePM: Project Management transposed online: The use of information communication tools to support inter-organizational project work2010Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    The purpose of this bachelor paper is to analyze the different technologies used for supporting inter-organizational project work and how these technologies influence the project’s overall success. The results of this research have proved that the main impact ePM tools (e-Project Management tools) have upon inter-organizational projects are in terms of time-savings and easiness of communication when in need for communicating abroad with different business partners. Various types of collaboration tools can help the communication process between organizations and provide the project participants with the means of creating and supporting a collaborative environment. Other perceived benefits of ePM tools have been resulted including: reduce project costs due to time-savings and quality of information which lowers the risks for deficiency occurrences; improve the decision-making process; improve internal and external communication; facilitate knowledge sharing and expertise exchange; and create an agile business environment characterized by innovation, flexibility, faster market reaction and ability to work efficiently. Global time zones and communication skills are challenges to creating an efficient collaborative inter-organizational environment.

    Svenska internetoperatörers beslutsprocess kring val av Wi-Fi-Router: En kvalitativ intervjustudie2023Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    This study investigates how Swedish internet service providers (ISP) choose a Wi-Fi-Router for use by private customers. The study investigates the process of choosing a Wi-Fi-Router and what features the companies prioritize during the process. These features can be aspects such as security, speed, capacity, Wi-Fi standard and price. The study seeks to answer how the decision-making process is carried out in the companies, but also how the Wi-Fi-Routers features are prioritized during the decision-making process. 

    This was investigated using qualitative methods in the form of semi-structured interviews. The interviews were held remotely, which allowed for a larger spread of respondents. After the interviews, the data was coded using thematic analysis to arrive at the results of the study. 

    The study identified several different phases during the decision-making process that ISP’s go through. After identifying the phases, they were placed in a model which seeks to describe the decision-making process for all ISPs. 

    The most important aspect during the decision-making process was the price. The remaining aspects were decided by the Wi-Fi-Router's price and compromises had to be made to lower the price to a reasonable level for both the company and the customer. In addition to the price, the companies aimed to find a balance between the other features, where compromises can be made for features they consider to be less important.

    Metod för att bestämma drifttid2015Independent thesis Basic level (degree of Bachelor), 10 poäng / 15 hpOppgave
    Abstract [en]

    The usage time is an important part of the specification for products powered bybatteries. The usage time is affected by a number of different elements; technical,environmental and how the product is being used. The method to determine theusage time is intended to define how measurements and calculations are to berealized along with influencing factors to keep in mind. With support from thismethod the intention is to gain control on how well the established usage time canbe expected to cohere with the real value and what affects the value.The study is done specifically for hearing protectors with battery powered built inelectronically functions. The functions can be level dependent function forambient hearing, 2-way radio communication, Bluetooth or FM-radio.The first chapter of the report describes the literature study performed in theproject. This study handles factors affecting measurements, factors with need tobe considered in the measurement situation and how deviations are handled.The following chapter begins with a description on previously used measurementtechniques for determination of the usage time. This is followed by a descriptionof three different methods developed in this project. A description of a couple ofmeasurements performed to investigate factors that affects the usage time is alsoincluded in this chapter.In the chapter describing the analysis of the study, the three methods developed inthis project are analyzed. This analyze is performed with the formulation ofquestion for the project, what has appeared in the literature study and themeasurements performed.The summary from the project includes factors affecting the measurement andhow to handle deviations in order to keep them as low as possible. The differentfunctions in the products affects the usage time in different proportions. Themost prominent factors are the balance of how much different functions are beingused when the usage time are decided, how batteries behave in different situationsand how the measurement equipment and the connection of the same affects themeasurement result.As part of the summary the advantages with one of the three methods developedare described and compared to the other two developed test methods. Thepreferred method uses usage time logging in real time during a test situation wherethe product is controlled to work in a situation trying to emulate normal use.

    Anti-collision algorithms and performance analysis for UHF passive RFID networks: IEEE Publication Titile (Optimal Dynamic Frame-Slotted Aloha)2011Independent thesis Advanced level (degree of Master (Two Years)), 20 poäng / 30 hpOppgave
    Abstract [en]

    Passive UHF RFID systems using Dynamic Frame-Slotted ALOHA (DFSA) adjust the frame size according to the number of tags, but frame size N is equals to 2^Q and cannot be adjusted exactly to the number of tags to be identified. In this thesis, we propose an optimal Aloha algorithm (ODFSA), which uses probabilistic approach for tags to access the frame. The Query or Query Adjust packet contains both the parameter Q and P called frame access probability, which represent the ratio of number of active tags in the current frame to the estimated total number of tags which remain to be identified in the system. Estimation of number of unread tags is updated after end of each frame; parameters Q and P are calculated and informed at the beginning of each frame.Our proposed ODFSA algorithm is purely built on EPC Global class-1 Gen. 2 standards. The proposed algorithm uses probabilistic approach instead of grouping. At the beginning of each frame, the reader sends a Query or Query adjust packet as in EPC Global Class-1 Gen.2 does, but the packet contains also a field called frame access probability, P. When a tag receives the packet, the tag generates a random value p. If p <=P, the tag participates into the current frame, otherwise it waits for the next frame. Estimation of numbers of unread tags is updated after end of each frame, parameters Q and P are calculated and informed at the beginning of each frame. Mathematical analysis and computer simulations show that the proposed Aloha achieves maximum system efficiency, utilizes less number of slots compared with other algorithms and also takes less identification time.

    Context-based Ontology-driven Recommendation Strategies for Tourism in Ubiquitous Computing2014Inngår i: Wireless personal communications, ISSN 0929-6212, E-ISSN 1572-834X, Vol. 76, nr 4, s. 731-745Artikkel i tidsskrift (Fagfellevurdert)
    Abstract [en]

    Tourism is an information-intensive business. At present, there are a lot of information and tourism resources available on the internet that lead to low searching efficiency and effectiveness, the user may get too many seeking results but not related to his interest, or few results than his expected. The user can know clearly what he wants, but sometime the user doesn't know what kind information he needs. User's demand can be formulated as direct demand and potential preference. At the same time, the study shows that there is strong relationship between the traveler's potential preference and the characteristics of tourism resources. In order to solve the information overload challenge, recommendation services are increasingly emerging. Currently, recommendation methods focus on dealing with personalized matching based on the user preference. However, these methods skip the user's direct demand. In this paper, we propose ontology-driven recommendation strategies based on user's context. The strategies use ontology to describe and integrate tourism resources, achieve the goal of associating user's direct needs and his potential preference as the context in recommendation. Moreover, theoretical analysis and experiments show that the proposed approach is feasible, the results of the evaluation are discussed.
