This topic defines the terminology used with Alibaba Cloud Link WAN.

Term

Description

Alibaba Cloud Link WAN

Also known as Link WAN.

Online merchant

A user who connects gateways to build a private network.

Application tenant

A user who uses credentials issued by a network tenant to connect devices and develop applications.

Device partner

A partner who manufactures and sells devices that meet the Link WAN access standards.

Service partner

A partner who has obtained a Link WAN interoperability certificate.

Gateway

A network element in a LoRaWAN access network. It is responsible for uplink and downlink wireless communication with endpoints.

Node

A terminal or module with LoRa communication capabilities.

Credential

A network access credential. In the LoRaWAN protocol, the credential is written to the JoinEUI of the associated node device. Each node group uses the credential to access a specific network.

Private credential

Access permission is limited to a user's private network.

Ubiquitous credential

Access permission can be used to join a ubiquitous network, also known as a shared network.

Frequency plan

The radio frequency band in which LoRa gateways and nodes operate, such as CN470 in China and AS923 in the Asia-Pacific region.

Class A

The most power-efficient operating mode for a LoRa node. The server-side cannot actively send data to the node. Uplink data is sent on demand.

Class B

The server-side can actively send data to the node. The node operates in a power-saving mode with controllable latency.

Class C

The server-side can achieve real-time, bidirectional uplink and downlink communication. This mode has high power consumption and requires a fixed power supply.

D2D

Device-to-Device operating mode. It enables point-to-point communication and supports active downlink wake-up.

GwEUI

The identity of a LoRaWAN gateway.

DevEUI

The identity of a LoRa node.

Data egress

The destination for a node group's data stream. It can connect to user applications and supports MSMQ and Alibaba Cloud IoT Platform.

CN470

The radio spectrum resource from 470 MHz to 510 MHz in China. It can be used within the scope permitted by laws and regulations.

AS923

The radio spectrum resource from 920 MHz to 923 MHz in the Asia-Pacific region. It can be used within the scope permitted by laws and regulations.

Intra-frequency

Uplink and downlink communication in a LoRa network use the same frequency.

Inter-frequency

Uplink and downlink communication in a LoRa network use different frequencies.

Hybrid gateway

A gateway with hybrid capabilities. It allows uplink and downlink data to be simultaneously connected to both a local edge gateway and a public cloud gateway.

Production line configuration

Supports factory production lines. Keys downloaded from the cloud can be burned onto devices during production.
