LoRaWAN is low power wide area network for short. It is applicable for wireless battery-powered devices in regional, national or global networks. According to the LoRa alliance, LoRaWAN can realize the key requirements of IoT, such as secure bidirectional communications, mobility and localization services.
The LoRaWAN specification enables the rollout of IoT applications by providing seamless interoperability between smart devices without the need for complex local installations.In LoRaWAN network architecture, gateways are connected to network servers via standard IP connections, while terminal devices use single-hop wireless communication to one or more gateways.
All endpoint communication is typically bidirectional, but also supports operations such as multicast, enabling broadcast communication time to be reduced through in-flight software upgrades or other mass distribution of messages.
Low power wan will be a major part of the growth of the Internet of things products in the coming years. LoRa’s main advantages are long range, low power and low-cost connections. Another key advantage of LoRa and LoRaWan is device and network security.
The LoRa alliance emphasizes that the LoRaWAN protocol offers many advantages in terms of bidirectional, security, mobility, and accurate localization that other LPWAN technologies cannot address.
