Our idea is simple, why don’t we create an application in android that can communicate using Radio Frequency signals. Android devices can’t communicate to each other directly through Radio Frequency. So we plan to make a small RF antenna (about the size of a pen) which can be carried easily. Android devices will make use of Bluetooth to connect to this antenna. And the antenna would transmit the messages in the form of Radio Frequency Signals. This way an effective communication can be established between a sender and the receiver without using any internet or mobile network data. By using this application, user can exchange in communication without a centralized mobile network. This can be implemented cheaply and effectively just by using a simple Arduino Board and an Android Device.

2. LITERATURE SURVEY In Paper [1], we have Wi-Fi Direct, which is a new technology defined by the Wi-Fi Alliance aimed at enhancing device to device communications in Wi-Fi. Thus, given the wide base Wi-Fi capabilities of the devices, and the fact that it can be entirely implemented in a software over traditional Wi- Fi radio’s, and this technology is expected to have a significant impact. Our results produce certain delays. These delays are to be expected in practice when Wi-Fi Direct devices discover each other and establish a connection.

1. INTRODUCTION
Paper [2], tells how to provide mobile users with costeffective wireless information services is becoming a hot topic for wireless vendors. This paper reports recent research and development efforts in constructing Mobile Jabber IM a wireless-based text chatting system,. It tells about the system architecture, system design, and technologies. The paper demonstrates the system application examples and shares the development and implementation experiences.
We have a wide range of chat application available in the internet. These applications have made our life easier by allowing us to connect with our friends and relatives in a split- second. So, it would be quite oblivious question that Now, why should we need a chat that uses RF signals. The answer is quite simple: Most of the chat application make use of internet which requires the user to connect to a Wi-Fi network which has data or the use rmust make use of data in his/her device, which is not economical. Of course, there are chats in android which work effectively in a Bluetooth/Wi-Fi network. But these technologies give a little range. i.e. The sender and the receiver must not be away more than 10 meters. This problem makes it quite impractical to use them.

In Paper [3], we have MultiNet, that facilitates simultaneous connections to multiple networks by virtualizing a single wireless card.There are many scenarios where it is desirable to have a wireless device which can be used to connect to multiple networks simultaneously.
