Increasing Data Transmission Reliability using Pseudo-spread-spectrum Short-Range Radio Networks

Wireless Sensor Networks (WSNs) have become a key technology in various fields, enabling efficient data collection and monitoring. However, the coexistence of Wi-Fi networks and WSNs operating in the 2.4GHz spectrum, such as those utilizing nRF24L01P modules, may be prone to interference and raise challenges to achieve a reliable data transmission. This paper aims to explore a novel approach to enhance data transmission reliability by employing pseudo-spread-spectrum short-range radio networks. The goal is to spread the spectrum of nRF24L01P modules over multiple channels, utilizing multiple radio receivers, each operating on a different channel, and enabling the transmitter to dynamically change its frequency if acknowledgements are not received. A comparative analysis has also been conducted to determine the effectiveness of spreading the spectrum in data transmission reliability enhancement.
