With the high availability of mobile phones nowadays, multimedia communication technology through wireless network has become more and more popular. However wireless communication relies heavily on commercial service provider using GSM or 3G networks. The general purpose of this project is to design and develop an integrated mobile solution which is capable of providing communication services through the WI-FI network on Symbian Phones. In this project, Nokia phones with Symbian OS v9.3 operating system are used to communicate with each other using WI-FI network operating at 2.4 GHz. The communication services can be in the form of chatting, image, audio and video files. The design and development process follows the methodology of modular design; different functions are developed individually. There are three phrases of the project. In the first phrase, basic functions such as taking picture, recording audio and video, composing text message, browsing file directory are implemented. In the second phrase, the main focus is on the transmission of data. It is initially developed to be able to transmit plain text messages over UDP. The students proceeded to transmit small size file over the network. Subsequently it continued to explore the possibilities to handle transmission of files of larger sizes which need fragmentation. Finally, this project involves integration of all the modules. Together with the development by a fellow student, the integrated solution has been produced with the capabilities of chatting, sending picture and audio as well as video data. This enables mobile phone users to stay wirelessly connected without the involvement of the commercial telecommunications provider.
