Spreading Factor, Bandwidth, Coding Rate and Bit Rate in LoRa (English)

In the previous article, I discussed about several basic Spread Spectrum concepts while specifically talking about LoRa modulation and touching the topic regarding several parameters in LoRa. Those parameters in question are Spreading Factor, Bandwidth, and Coding Rate. The three parameters will determine how sensitive the LoRa receiver will perform and how fast the dataLanjutkan membaca “Spreading Factor, Bandwidth, Coding Rate and Bit Rate in LoRa (English)”

LoRa Modulation Basics (English)

LoRa is a spread spectrum modulation technology patented by Semtech. LoRa is a derivative of┬áChirp Spread Spectrum (CSS) which lowers data rate to improve sensitivity. If you want to place LoRa in the OSI Layer, implementation of LoRa modulation exists on the physical layer and can’t be bound to other layers above it. This allowsLanjutkan membaca “LoRa Modulation Basics (English)”
