Due to high interference, LoRa\u00ae cannot yet reach more than 2 kilometers when installed in populated locations such as cities. Furthermore, most off-the-shelf LoRa\u00ae Nodes are power-hungry and cannot operate on battery power for more than three days.<\/p>\n\n\n\n

To improve the situation of high dependence on power and the narrow transmission range of LoRa\u00ae in the urban area, Aiman Akid<\/a> deployed an optimization project for LoRa\u00ae point-to-point network. The purpose of the project is to build two optimization strategies and then assess the node’s operation. The first is the RTOS approach, which is Deep Sleep<\/strong>, to minimize the power consumption of the LoRa\u00ae sensor node. And the other is adding another LoRa\u00ae node as an intermediary node to extend the network transmission distance. To view the original project on hackster.io, please refer here<\/a>.<\/p>\n\n\n
