What is LoRa? (2020) | Learn Technology in 5 Minutes

Hello and welcome to another episode of “Learn Technology in 5-minutes from MAKERDEMY. In this video, we will learn about LoRa, the low power wide area network technology for the Internet of Things. You are familiar with Wide Area Network technology like the cellular 4G and 5G which allow data transmission over long distances. However, cellular WAN consumes a lot of power. How often do you charge your mobile phone? I charge my phone every day. Cellular WAN allows us to transmit large amounts of data at high speeds over long distances. The trade-off here is high power consumption. Now let us think of an IoT solution wherein we have wireless sensor nodes spread over a few kilometers to transmit their sensor values via a network a few times every hour. Furthermore, these nodes operate on batteries that are supposed to run at least for a couple of years. These nodes can’t be mains charged like your mobile phone. The data transmitted will be small and sporadic. Under such conditions, we need a wireless network t
