ANALYTICAL STUDY OF DEDICATED NETWORK FOR IOT USING LoRaWAN TECHNOLOGIES

The Internet of things (IoT) is invasive our lives by connecting encompassing human things to the internet. In this paper, we've got an inclination to addresses the long range wide area network (LoRaWAN) that pulls various attentions primarily by their ability to produce lowcost property to the low-power devices which are distributed over very huge geographical areas. LoRaWAN offers radio coverage over very huge area by approach of base stations and adapting transmission rates, transmission power, modulation, duty cycles, etc., such end-devices incur awfully low energy consumption due to their being connected.

A study of LoRa low power and wide area network technology

2017 International Conference on Advanced Technologies for Signal and Image Processing (ATSIP)

LoRa T M is low power wide area wireless network (LPWAN) protocol for Internet of Things (IoTs) applications. LPWAN has been enabling technology of large scale wireless sensor networks (WSNs). Effective cost, long range and energy efficiency of LPWANs make them most suitable candidates for smart city applications. These technologies offer novel communication paradigm to address discrete IoT's applications. LoRa is a recently proposed LPWAN technology based on spread spectrum technique with a wider band. LoRa uses the entire channel bandwidth to broadcast a signal which makes it resistant to channel noise, long term relative frequency, doppler effects and fading. This paper focuses on the emerging transmission technologies dedicated to IoT networks. Characteristics of LoRa are based on three basic parameters: Code Rate (CR), Spreading Factor (SF) and Bandwidth (BW). This paper provides in depth analysis of the impact of these three parameters on the data rate and time on air.
