Corporate Wireless IP TelephonyGarcía Hijes, Raúl January 2005 (has links)
IP telephony is defined as the transport of telephony calls over an IP network. IP telephony exploits the integration of voice and data networks. However, enterprises are still reluctant to deploy IP telephony despite the potential increase in productivity and reduction of costs. The principal concerns are: can IP telephony provide the same level of performance in terms of security, reliability, and scalability as traditional telephony? If so, are its proclaimed benefits such as flexibility and mobility cost-effective? The aim of this thesis is to analyze how to deploy IP telephony in large corporations - while providing the necessary security and facilitating mobility. Through the different parts of this thesis, we will analyze the applicable technologies, along with their integration and management. We will focus on the essential requirements for an enterprise of scalability, reliability, flexibility, high-availability, and cost-effectiveness. The massive changes brought about due to the deregulation of telecommunications in nearly all countries, the increasingly global nature of business, and the progressively affordable and power technology underlying information and communication technologies have lead to increasing adoption of IP telephony by residential and commercial users. This thesis will examine these technologies in the context of a very large distributed corporation. / IP telefoni är definierat som transporten av telefon samtal genom ett IP nätverk. IP telefoni utnyttjar integrationen av tal och data nätverk. Dock är affärsföretag fortfarande motsträviga till att införa IP telefoni trots potentiell ökning i produktivitet och minskade kostnader. Huvud bekymren är: kan IP telefoni tillhandahålla samma nivå av prestanda med avseende på säkerhet, tillförlitlighet, och skalbarhet som traditionell telefoni? Och i så fall, är dom proklamerade fördelarna flexibilitet och rörlighet kostnadseffektiva? Målet för detta examensarbete är att analysera hur IP telefoni kan införas i stora affärsföretag - medan samtidigt tillhandahålla nödvändig säkerhet och främja rörlighet. Genom olika delar av detta examensarbete, analyserar vi tillämpliga teknologier, inklusive deras integrering och skötsel. Vi kommer att fokusera på de grundläggande kraven för ett affärsföretag gällande skalbarhet, tillförlitlighet, flexibilitet, hög tillgänglighet, och kostnadseffektivitet. Dom massiva förändringarna frambringade i och med avregleringen av telekommunikation i stort sett alla länder, affärsverksamhetens alltmer globala natur, och de progressivt kostnadseffektiva och kraftfulla underliggande teknologier bakom informations och kommunikations system har lett till ökande adoptering av IP telefoni av både privata och kommersiella användare. Detta examensarbete undersöker relevanta teknologier i samband med mycket stora utbredda affärsföretag. / <p>Exchange student from Centro Politecnico Superior (University of Zaragoza, Spain).</p>

Exploring the influence of size and geography on SMEs’ and large corporations’ CSR practices in Hungary and in Sweden when facing financial shortageGaál, Bence, Vágó, Georgina January 2022 (has links)
Background: CSR has become an integral part of most businesses during the years, however, it has not necessarily happened by choice for every company. Stakeholders have become aware of the negative impact ofcorporations’ operations and actions on the planet and on society, consequently, they started to pressure companies to be more responsible when conducting business. However, facing financial shortages might interfere with the accomplishment of these practices and corresponding activities. Furthermore, as differently sized and differently located companies might practice CSR in a different way, size and geographical location might also have an influence on these CSR practices and activities. Purpose: The purpose of this research is to explore the influence of size and geography on CSR practices and activities adopted by SMEs and large corporations in Sweden and in Hungary when facing shortage in their financial resources. Method: In order to achieve the purpose, a qualitative research method has been used. Multiple case studies were conducted with two Hungarian SMEs, a Hungarian large enterprise, a Swedish SME and a Swedish large firm. The empirical data was collected with the help of semi-structured interviews as well as data from corporate websites, annual reports, sustainability reports and social media. Conclusion: The results of this thesis show that the approach each company takes to practicing CSR seems to influence all of their activities. The size of the company appears to influence fewer practices, while geography comes across as having the least influence among these factors.
