<p>Mobile Phone, without this we can’t think to pass a day in presence. We have found a rapid increase of mobile phone users from a few years ago till now. Day by day the modern technologies allow the mobile phone to become smaller, cheaper, and more reliable.

We measured the field intensity at near field and estimated the field strength at the far field region at 3 meters. To measure the field intensity and the effective radiated power we used HR1 near field scanner.

Furthermore, we measured our DUTs at 3 meter with a far field measurement system with optical fiber connection. A feasible relation between field strength and measured power was defined in order to correlate the near field scanner results with the far field measurement system.</p><p> </p><p>This paper also provides a short design guide line for built in FM antennas by relating the antenna size and placement to input power and the field strength in mobile phone FM transmitter application</p>

The high penetration rate of mobile phones along with the recent technological development has created a whole new marketing medium named mobile advertising filled with possibilities for the advertisers. Earlier studies have although indicated the success of this new advertising channel to depend on user acceptance of receiving mobile ads. Wherefore a study of consumer attitudes towards mobile advertising can be considered necessary in order to create a lucrative business. Even though this topic is relatively new several studies have already been gathered concerning user attitudes towards mobile advertising, mostly in Asian countries. Our paper aims to fill up the research gap by targeting the research to young adults in Sweden and providing thus with a study on young adult attitudes towards mobile advertising and the factors affecting them, in Sweden. To be able to see if any relation between existing literature and empirical data exists four hypotheses have been constructed. This paper has identified user acceptance of advertising, user-based characteristics, advertising characteristics, as a well as mobile service characteristic to be main consumer acceptance drivers of mobile adverting. The four hypotheses set up for the paper could be confirmed with the help of a Pearson correlation test, which showed a significant relationship between all tested variables and a weak positive correlation. The relations are though weaker than the previous literature declares. Further results of this paper indicates that users are in general negative towards mobile advertising, and that permission and incentive based services most likely are to influence consumer attitudes towards the service.

This project has been made in collaboration with the company Tinitell in Stockholm. The purpose of the project is to design mobile phones for children. This report explains all the Design Process, as SVID (Swedish Industrial Design Foundation) describes it. It starts with a research phase and according to its conclusions, a concept generation phase follows. After discussing the possible concepts, the best alternative is selected and developed. The final part of the report is the analysis and conclusions of the whole process. / Detta projekt har genomförts i samarbete med Tinitell i Stockholm. Syftet med projektet är att ta fram en design på mobiltelefoner anpassade för barn i åldrarna fem till elva år. Frågeställningen som skall besvaras i denna uppsats är ”Hur bör dessa telefoner fungera, och hur bör de se ut?” Målet har varit att ta fram en design som är häftig och innovativ men samtidigt enkel och rolig för barn att använda. Den skall även vara en trygghet för föräldrarna då den möjliggör kommunikation mellan förälder och barn vart som helst, när som helst. Projektet började med en omfattande undersökning bestående av observation av barn som hanterar mobiltelefoner, vilka problem som uppstår och vad man kan utveckla för att tillgodose barns behov, utöver detta genomfördes även tre stora enkäter. Barn i olika åldrar hanterar saker på olika sätt beroende på karaktärsdrag, utveckling och beteende. Baserat på detta faktum togs beslutet i början av arbetsprocessen att dela in användaren i tre olika åldersgrupper. Övergångsåren (5- 6 år), mellanåren (7-9 år) samt yngre ungdomsåren (10-11 år). Utifrån de första skisserna valdes tre olika koncept ut, ett för varje åldersgrupp. Trots att alla tre telefoner har samma grundfunktioner har de, beroende på åldersgrupp, olika extra funktioner och olika utformning för att på bästa möjliga sätt passa slutanvändaren. De tre skisserna presenterades för Mats Horn, grundare av Tinitell. De hade dock räknat med att göra en fast investering och valde därför att fokusera på produktion och design för en av modellerna. För att kunna välja ut ett av koncepten genomfördes en ”value opportunity analysis”, efter att ha tolkat resultaten från denna undersökning valdes koncept två (7-9 år) ut för vidareutveckling. Efter att ha gjort flertalet digitala 3D-modeller och provat många olika idéer nådde jag slutligen mitt mål vad gäller design och funktion för telefonen. Resultatet är Tiniphone, en mobiltelefon med touch-screen utformad som ett armband som barnet kan fästa på armen. Alla funktioner i Tiniphone kontrolleras av föräldrarna via en dator. Detta projekt har genomförts parallellt med Tinitell, som jobbar på en liknande produkt. Jag är väldigt nöjd med slutresultatet och jag hoppas att Tinitell kan använda det material jag framställt som hjälp och inspiration för att hitta en slutdesign för telefonen.

Methods to improve self-care and clinical management of heart failure are required, especially in light of the anticipated increase in heart failure prevalence and associated high costs. Remote patient monitoring (RPM) has been shown to improve heart failure outcomes, but the feasibility and efficacy of mobile phone-based RPM systems are still unknown. The main objectives of this research were to investigate the optimal design of a mobile phone-based RPM system, and to determine the effects of the system on self-care, clinical management, and health outcomes. A mobile phone-based RPM system was first developed using a user-centric design process. It was then evaluated with a six-month randomized controlled trial consisting of 100 patients attending a heart function clinic. The quality of life improved only for the intervention group, but both intervention and control groups improved with respect to self-care, heart function, and heart failure prognosis. The clinic was determined to be a confounder. Patients who were enrolled into the clinic for less than six months showed significantly greater improvements (six months is required for patients to stabilize from medication optimization). Therefore, a subgroup analysis using data from the 63 patients who were enrolled into the clinic for over six months at time of recruitment was performed. The results from the subgroup analysis indicated that the RPM system improved self-care, heart function, and heart failure prognosis at statistically significant and clinically meaningful levels. These improvements were found to be a result of enhanced self-care knowledge and practices, as well as enhanced clinical management enabled by the system. No differences in mortality or hospital admissions were found between groups, but the trial was underpowered to detect changes in these outcome measures. In summary, mobile phone-based RPM was found to be a feasible and effective tool to help improve heart failure management and outcomes.

Mobile Phone, without this we can’t think to pass a day in presence. We have found a rapid increase of mobile phone users from a few years ago till now. Day by day the modern technologies allow the mobile phone to become smaller, cheaper, and more reliable. This also creates new possibilities for applications and integrations of the classical broadcast systems and modern mobile phone technologies. One example is the FM transmitter in mobile phone. The FM transmitter in a mobile phone is a “cool” feature which allows listening to the music content in phone on a car or home radio.   This thesis work deals with the near field characterization of FM transmitters in mobile phone applications. The RF scientists and engineers neglect the near field zone because typical RF links operate at distances of many wavelengths away where near field effects are totally insignificant.

In this thesis we introduce a half-wavelength loop antenna for operation as an internal antenna for mobile phones. First, we introduce a single loop antenna for single-band operation (eg., UMTS band), and experimental and simulated results are presented. Next, we introduce a dual-band loop structure which covers the operating bandwidths of the GSM/DCS dual-band mobile phone. The proposed dual-loop antenna is studied, especially for the effects between the two loops of the antenna. Both of the single-loop and dual-loop antennas have the characteristics of generating similar surface currents on the ground plane with that of the conventional monopole and planar inverted-F mobile phone antennas.

Telecom market was opened due to the demand of Taiwan¡¦s joint WTO and Mobile operator became a ¡§new star¡¨ business then. The first private-owned telecom operator launched service in 1997, then, mobile phone penetration rate grew up rapidly from 6% of 1997 to more than 100% of 2003. Taiwan¡¦s mobile phone penetration rate has ranked No.1 in the world; meanwhile, mobile operators in Taiwan also faced the challenge of the coming new telecom era-mobile value added service. Mobile value added service was introduced to Taiwan market 5 years ago and it became the theme of competition within these two years. Most of the papers were focused on the entire telecom competing strategy, very few of them were involved the study of value added service. The study, therefore, tries to adopt case study to analyze the difference of key players in the market and hope to provide recommendation to those players in mobile telecom market. Following are the major discoveries: A. The marketing strategy and key elements of value added service of those key players are too similar to cause the competitive advantage B. Players are eager to win in launch timing and therefore, lack of solid marketing survey and study. C. Players need to enhance the conception and operation for service marketing because most of the marketing operation were still based on traditional 4P D. When there is no difference in either products or strategy, successful and complete execution will lead to the final succeed.

The growth rate in the field of Computer, which is one of the traditional 3C industries, has been getting slower in recent years, then Communication replaces it and serves as the main driving force to keep the 3C industry growing. The author chooses mobile phone as the main subject of the thesis to analyze since mobile phone is the product which has the largest market share and the greatest potential for growth in the field of Communication. Under current trend development of mobile phone, the thesis aims to analyze and investigate 1)the product architecture of mobile phone; 2) what kind of change it has on the business architecture of mobile phone chip manufacturer; 3) what kind of impact it brings on chip manufacturer which works in concert, i.e. Foundry Fab. The research begins with the analysis of the application terminal of market. The author classifies the mobile phone into two categories, namely, low-end and high-end, and organized the collected information/data about the current market demand of mobile phone, changes of internal mobile phone devices, and requirements on Foundry OEM services. Also, data/info about the strategic activities of leading mobile phone IC chip corporations are collected and organized; the collected data will be presented and analyzed. Finally, the analysis will be the base, which the conclusion will be drawn upon. The study discovers that the original product architecture of mobile phone displays an ¡§integral-closed¡¨ structure; however, under current trend development of mobile phone, the low-end mobile phone had changed into a ¡§modular-closed¡¨ structure, even increasing the ¡§open¡¨ degree. The product architecture of high-end mobile phone is characterized by ¡§integral¡¨ and ¡§modular¡¨ since the specifications of internal devices of high-end mobile phone are more complicated and still not established yet. Moreover, the high-end mobile phone is in the stage of development, together with the addition of new functions, which in turn resulted in a perplexing and uncertain business environment. Therefore, companies often form strategic alliances in order to reduce the risks of developing new products in an unstable business environment. The competition pattern has changed from ¡§firm against firm¡¨ to ¡§alliance against alliance¡¨. Hence, we can tell the impacts resulted from the change of product architecture on business architecture. Finally, the answers of some questions are still cannot be found not due to the limitation of the study. Therefore, a list of unsolved questions is given in the end of the study so as to form an initial lead in the development of a ground for further research.

An internal small antenna usually suffers from degradation in performance of impedance bandwidth and radiation patterns. In this thesis, we design and fabricate a broadband interior type planar monopole with an omni-directional radiation pattern over a wide operation band using a slant feeding strip. It has a measured impedance bandwidth about 465MHz with center frequency at 1.66GHz (1427 ¡V 1892MHz) and the maximum cross polarization level about -13dB at 1800MHz, which is GSM1800 band in mobile communications. A modified design is an interior planar monopole with a slant slit. It has a measured impedance bandwidth about 455MHz with center frequency at 1.71GHz (1487 ¡V 1942MHz), including GSM1800 and PCS1900 band, and the maximum cross polarization level about -15dB at 1800MHz. The antennas have the dimensions of 40mm*15mm which occupies a small size on the system board and they are suitable to be mounted within the mobile handset device.
