Multiuse Text Messaging by RF is the exchange of brief written text messages between two or more portable devices. Secured wireless communication plays an important role for military, office, industry. Multiuse Text Messaging by RF project is specially made for wireless communication. It doesn’t need any networking service. As many times we need to communicate within a campus or a small area. So, this project can use for this purpose without paying messaging bill. The major point of this project is that it is secured wireless communication. Transmitter encodes the message before sending it which couldn’t decode easily by any receiver. Our receiver circuit knows the decoding format so it easily decodes and user can read the message. In this way user can get securely communicates with each other.
This project is used to communicate or transmit a text message from one place to another place through wireless. The text message is encrypted by using the Microcontroller and the encrypted message was transmitted through wireless Zigbee. At the receiver end the signal was received by the standard receiver and the analog signal was fed to the Microcontroller and it was decrypted by the Microcontroller and the message was displayed over the LCD display.
