TopIntroduction
Currently there are a number of wireless communication technologies that can be used to connect a device to the internet. Every application is based on factors such as range, data rate, cost, power consumption, volume and form factor that have to be considered. This paper provides an insight to the LoRaWAN and compares its advantages to other protocols. It also discusses how LoRa can be efficiently implemented for IoT applications.
Every technology has both merits and demerits. For example, Wi-Fi can transmit large amount of data at high speed, but it has a limited range of operation. A cellular network provides high speed and long range, but its power consumption is high. IoT applications such as remote data acquisition, urban lighting control, weather monitoring, and agriculture, each have a different set of priorities. The amount of data being estimated or controlled in these applications, for example, climate conditions, soil dampness levels, or streetlights, all change gradually over an expanded time-frame. What's more, the sensor hubs are frequently miles separated and are battery operated, so the ideal remote convention must have the capacity to send information bundles effectively over long separations with least power utilisation. The LoRa convention was intended for precisely these necessities. LoRa is focused on Low Power Wide Area Network (LPWAN) applications.
LoRa is used for long range and low power communication between the node and the server. This is done by isolating the node and server by introducing a gateway. The packet sent by the node to the gateway is encrypted and uplinked such that it would consume just a fraction of the power as compared to direct uplink to the server. Since LoRa is relatively new technology the main objective of the research would be to develop a node (end device) which operates on an independent power source to collect data points. This method of acquiring the data has proved to be power efficient.
