Análise de ferramentas e tecnologias de acesso a internet via dispositivos móveis

Abstract

This work presents an analysis of the access technologies available and of some content conversion tools for Internet access using mobile devices. On the first part of this work the evolution of the protocols and technologies available for mobile access is presented. This evolution provides mobile data transfer rates comparable to those available for desktops. Analisys and comparison of some content conversion tools was performed in the second part of this work. Eight sites were accessed by a Palm Treo 650 smartphone, using different content conversion tools. The results were compared considering the amount of data transfered and visual presentation of the pages. Although it is possible do view web content directly from the standard browser available in the device, the use of conversion tools reduced limitations and errors, providing a better content display. The use ofthese tools also provided a reduction on the amount of data transfer, resulting in higher access speed and in the possibility of access cost reduction.
