LoRa propagation at 433 MHz in tropical climate environment

Abstract

LoRa employs chirp spread spectrum technology and being consider spread spectrum technology and being considered as one of the promising system for Low-Power -Wide-Area-Network (LPWAN) to supp ort the growth of Internet of Things (IoT) applications ) applications. Designed to operate in the industrial, scientific and medical (ISM) bands, LoRa had been tested and evaluated mainly in Europe and US in the bands, LoRa had been tested and evaluated mainly in Europe and US in the 868 MHz and 915 MHz modulation bands. This paper provides some initial results in the 868 MHz and 915 MHz modulation bands. This paper provides some initial results in the performance of LoRa signal propagatio performance of LoRa signal propagation of 433 MHz modulation in tropical climate environments.
