Alliance members include chip manufacturers, module suppliers, equipment manufacturers, telecom operators, system integrators and cloud service providers.
Main work:
Standardization: Release and maintain LoRaWAN protocol standards to ensure interoperability and compatibility.
Certification program: Provide certification for LoRaWAN devices and solutions to ensure that devices meet standard specifications.
Ecosystem construction: Promote cooperation in all links of the industrial chain and build a complete LoRaWAN ecosystem.
1.2 LoRaWAN protocol version
LoRaWAN 1.0: Initial version, defining the basic network architecture and device communication mechanism.
LoRaWAN 1.1: Enhanced security and roaming capabilities, supporting more device classifications and network functions.
LoRaWAN 1.2 and above: further optimizes performance and security, supports more efficient network management and application development.
1.3 Technical Specifications
Physical layer: Based on LoRa modulation technology, adopts Chirp Spread Spectrum (CSS) modulation method, supports long-distance, low-power communication.
MAC layer: defines basic communication operations such as device access, data transmission, and confirmation mechanism to ensure the reliability and security of data transmission.
Network layer: manages device access authentication, data routing, spectrum resource allocation, etc. to ensure efficient operation of the network.
Application layer: supports multiple application protocols, such as CoAP and MQTT, to facilitate application development and integration.
