Abstract

Low Power Wide Area Network (LPWAN) satellite communication has an emergency feature that offers hope for future IoT communication systems,as it is certain to avoid problems and obstacles or barriers that occur,such as obstacles and limited distance in terrestrial-based LPWAN telecommunications. Resilience in the transmission process is determined by signal strength over a wide bandwidth,little interference that causes signal attenuation,and also allows communication using batteries and small transmission power,as well as superior security systems that can face the challenges of very long distances and also overcome high signal attenuation. As well as a communication system that can be effectively used in the process of transmitting data in active conditions,with a low signal-noise ratio (SNR) indicator and a Receive Signal Strength Indicator (RSSI) that remains stable. So,using DSSS (Direct Sequence Spread Spectrum) in the future will have a significant impact on the attenuation of the signal that occurs. From the results of the method comparison,Processing Gain (dB) using Traditional DSSS is 21 dB,while using DSSS Improvement for LPWAN can increase to $\mathbf{2 1 ~ d B}$.
