New Project - LoRa

New Project - LoRa

What is LoRa?
LoRa is a wireless technology developed to create the low-power, wide-area networks (LPWANs) required for machine-to-machine (M2M) and Internet of Things (IoT) applications. The technology offers a very compelling mix of long range, low power consumption and secure data transmission and is gaining significant traction in IoT networks being deployed by wireless network operators.
A network based on LoRa wireless technology can provide coverage that is greater in range compared to that of existing cellular networks. In fact, many mobile network operators have chosen to complement their existing cellular/wireless networks with a LPWAN based on LoRa technology because it is easy to plug into their existing infrastructure and also allows them to offer their customers a solution to serve more IoT battery-operated applications.
