Abstract

The rise of mobile phone technology and the internet (TCP/ IP) which still computer increase hope to integrate them. The internet is part of worldwide telecommunication system and mobile phone is symbol of high mobility. The integration between mobile phone and the internet will provide everyone with much easier telecommunication. Developing internet application in the mobile phone will be an interesting area of information technology. Fortunately, Java has developed new platform Java 2 Micro Edition which especially use for developing for limited device configuration such mobile phone and PDA.. Applying internet protocol in the mobile phone would be very challenging as the protocol was designed for computer. Compare to computer, mobile phone has a lot of limitations such as less memory space, smaller user interface, smaller input device and unreliable cellular network. These limitations occur because mobile phone is small device. Hardware quality and unreliable connection will create limited quality software development above. Obviously, mobile phone firmware will have a lot of limitation, especially to implements internet protocol. The objective of this research is to evaluate the quality of internet protocol used in the Java based mobile phone. FTP Client developed using Java 2 Micro Edition is used for the evaluation process. Evaluation was conducted by comparing the quality network connection when the application was running in the 3 different environments. First, the application was run in an emulator which used in Windows XP Operating System in a computer wired network. Second, the application was run in an emulator used in Windows XP Operating System in an GPRS cellular network. Third, the application was run in the mobile phone using GPRS cellular network. The experiment results show that there is no difference between computers wired network and GPRS cellular network. However, the comparison between second and third experiment result show some differences. In the third experiment, it was found that there are some errors when the application is closing the connection to the FTP Server. This error shows that the internet protocol in the firmware is different from the computer using Windows XP Operating System. Closing connection standard in the internet protocol is not fully implemented by the mobile phone firmware.
