What's LoRaWAN?

LoRaWAN (Long Range Wide Area Network) is a low-power long-distance wireless communication technology that uses unlicensed frequency bands (Sub-GHz bands) to achieve wide-area, long-distance, low-speed, and low-power communication.

What's the Applications of LoRaWAN?

Smart Cities, Smart Buildings, intelligent public transportation, IoT manufacturing, location information tracking of logistics goods and personnel, environmental sensing, smart agriculture, etc.

What's the Communication Protocol Stack of LoRaWAN?

The communication protocol stack of LoRaWAN includes the physical layer, data link layer and network layer. The physical layer uses LoRa modulation technology, the data link layer uses MAC protocol, and the network layer is responsible for device registration, identity authentication and key distribution.

What's the Advantage of LoRaWAN?

Low cost: No need for operator's communication network, users can build and operate their own network.
Flexibility: Not limited by operator's service area, independent network environment can be built.
Security: Provides device authentication, data encryption and integrity protection

What's the Project of LoRaWAN?

Cisco has deployed LoRaWAN-based gateways in some of Dubai's smart cities as part of its IoT connectivity technology
