Web based system for radio planning in WRAP

Shakya, Nabin Raj January 2009 (has links)
<p>Radio planning is designing of network structure and elements under various design requirements. With the increasing shortage of frequencies, radio planning has become more and more complex. Hence, to maintain accuracy and optimization computerized planning tools are needed.</p><p>This thesis focuses on developing a simplified and economical solution on web for radio planning tool using WRAP- the software for spectrum management and radio planning developed by WRAP International AB, Linköping, Sweden. In order to make WRAP calculations available for remote users it had developed APIs. The web-based WRAP needs to communicate with WRAP API server, for exchanging API messages in order to perform calculation. To make the system user friendly and interactive, latest web technologies are implemented.</p><p>In this thesis, we started development process right from requirements gathering to find out required components that need to be analyzed to find suitable web-based conversion. Further, we designed and implemented a software solution. The final part is evaluation to discover if requirements are fully implemented or not as well as to gather the performance result of the new system. It is found, the performance of web based WRAP is equally fast as desktop version for smaller coverage areas whereas, for larger coverage areas, web-based WRAP is slower than desktop version</p>

[en] GSM COVERAGE SYSTEM PLANNING WITH REPEATERS / [pt] PLANEJAMENTO DE COBERTURA DE SISTEMAS GSM COM USO DE REPETIDORES

BRUNO MAIA ANTONIO LUIZ 16 September 2002 (has links)
[pt] Este trabalho aborda a utilização de repetidores na implantação de sistemas móveis celulares. Esta técnica permite estender a cobertura dos sistemas móveis celulares com baixo custo e curto tempo de implantação a áreas ou ambientes onde a utilização de estações rádio base seria dispendiosa ou demorada.O impacto da inclusão deste elemento na interface rádio é detalhadamente analisada visando obter uma metodologia para o seu dimensionamento e para o cálculo das degradações produzidas na rede. É apresentada ainda uma metodologia completa para projetos com repetidores e descrita sua aplicação na implantação de um sistema GSM. / [en] This work deals with the use of active repeaters in the planning and deployment of cellular mobile systems. This technique allows the extension of the coverage of the cellular systems, with low cost and short building time, to areas where the use of radio base stations would be costly or difficult to implement.The impact of the inclusion of the active element in the radio interface is analyzed in full detail to provide methods for the calculation of the degradations produced in the network. A complete design methodology for projects with repeaters is also presented, as well as a case study for a GSM system.
