LoRaWAN

Definition

LoRaWAN (Long Range Wide Area Network) is a low-power, wide-area networking protocol designed for wireless communication between devices, particularly useful for IoT applications. It enables long-range transmissions with low power consumption, making it ideal for implantable and wearable sensors that need to transmit data over extended distances without frequent battery replacements or recharging.

5 Must Know Facts For Your Next Test

1. LoRaWAN operates in sub-gigahertz frequency bands, allowing it to achieve communication ranges of up to 15 kilometers in rural areas and several kilometers in urban environments.
2. The protocol uses spread spectrum technology to increase resistance to interference and enables secure data transmission through encryption.
3. LoRaWAN is particularly beneficial for battery-operated devices, as it can allow them to run for several years on small batteries due to its low power requirements.
4. It supports a large number of devices in a single network, making it scalable for various applications, including smart cities and healthcare monitoring systems.
5. LoRaWAN networks can be configured in a star topology where multiple sensors communicate with a single gateway, which then connects to the internet, simplifying network architecture.
