Abstract
LoRa WAN is a newly emerged game changing communication technology for sending small data packets of size 50 bytes or less, wirelessly over an area of up to 10 Km without the need of an internet connection. LoRa WAN has its own frequency band and the band is different for every country. This technology is now starring to boost WSN technology better than ever before. This paper aims to, power up a LoRa Enabled Device or a LoRa Gateway by using a reliable dual mode non-conventional energy resource for storage and utilization, find peak performances altering the data rate that can be achieved in a LoRa WAN Communication (using Indoor RAK Gateway), make use data compression techniques, data packet encoding / decoding, Coding Apple Shortcuts, setting up Siri and Google Assistant for voice control and future scope.
Highlights
LoRa WAN is a ground-breaking technology based on spread spectrum modulation techniques derived from chirp spread spectrum technology which was developed by Cycleo of Grenoble, France and later acquired by Semtech which led to the development of the LoRa Alliance [1]
In the year 2015, Kaur N and Balguvhar S proposed the use of an embedded Piezoelectric Transducer (PZT) patches in Structural Health Monitoring (SHM) which can be made use of to harvest energy and can be stored to a capacitor or even a battery which can later be used for the purpose of SHM, the same PZT patch and a Concrete Vibration Sensor (CVS) was used as sensors, they showed that the picoelectric activity from the vibrations caused by the bridge and the produced energy can be harnessed to power up tiny devices with or without a battery[2]
It can be concluded that the receiving end could have a LoRa gateway or another Heltec’s ESP32 LoRa SX1278 which can make use of the harnessed power which is stored in the storage cell
Summary
LoRa WAN is a ground-breaking technology based on spread spectrum modulation techniques derived from chirp spread spectrum technology which was developed by Cycleo of Grenoble, France and later acquired by Semtech which led to the development of the LoRa Alliance [1]. LoRa WAN was created to overcome the need of an internet connection or a physical connection and its hurdles for long distance transmission of sensor data, this doesn’t mean that it wouldn’t cause hurdles for laying and using physical electric power supply connections which may be vulnerable to power failures. To overcome these convectional power supply issues we could make use of a reliable non-conventional energy source such as Piezoelectric and Solar power. The frequency at which LoRa WAN communicates is different for each country, the frequency band that is bound to be used in India is IN865
