Abstract

The paper presents a radio frequency data transmission system between PCs or other units communicating via the RS-232 interface. The main functionality of the proposed system is to transfer data between two PCs without any cable connection. The heart of the circuit is a Telecontrolli radio frequency module. The main task to control the data transfer is done by a PIC microcontroller. Since the wireless communication is noisy, a special error recognition and correction algorithm and a protocol using them were developed. Both are implemented in the microcontroller. The error correction algorithm is Hamming coding.
