Abstract

The growing demand for reliable and cost-effective wireless communication systems for applications such as remote monitoring, control systems, and Internet of Things (IoT) networks highlights the challenges posed by existing technologies, including latency, limited range, and high-power consumption. This study focuses on the design and development of a full-duplex wireless transceiver system operating at 433 MHz, utilizing commercially available RF circuit modules. The objective is to enable simultaneous bidirectional data transmission, thereby enhancing communication efficiency while minimizing latency. The transceiver system was constructed using 433 MHz RF transmitter and receiver modules, microcontrollers for signal processing, and optimized antennas to ensure stable communication. The design incorporates features aimed at achieving low power consumption, compact circuitry, and advanced noise suppression. Experimental evaluations were conducted to assess performance and communication range. The system demonstrated reliable bidirectional communication within a 100-meter range. Its low power consumption and effective noise suppression ensured efficient operation with minimal interference, making it suitable for short-range applications. The full-duplex transceiver system offers a cost-effective and efficient solution for short-range wireless communication, with potential applications in IoT networks, remote monitoring, and control systems. It provides a solid foundation for further advancements in wireless technology.
