Abstract

Wi-Fi technology is a form of telecommunication that allows data and voice transmissions to be sent across a wide range of interconnected networks. The success in deploying services and applications based on this concept needs the development of applications that allows intermediate users the reception and forwarding of information to destination users. The user may take the maximum benefit from the technology acquired inside the mobile phone for instance, since it is possible extend the radio coverage by several hops, and enjoy similar mobile2018;s operator services free of charge. In this work we are going to present the development of an integrated Java application to send SMS and Voice among user mobile phones through its WIFI interface. A software application is developed using Android which allows free and secured communication between selected phones in the Wi-Fi network. The base idea is unifying voice and data onto a single network infrastructure by digitizing success of wireless and mobile communications has resulted in the creation of a large variety of technologies. Expanding services through the use and coordination of these diverse networks will provide user mobility between different types of systems.
