IoT sensors are a vital tool for organizations. They can provide you with the information that was previously inaccessible. With IoT sensors, a lot of items and environmental features can be monitored, cataloged, and optimized for the best possible business performance.
What happens if I take a sensor outside of the range of the GW?
The sensor has no knowledge of the coverage areas of the gateway so it will continue to transmit as configured until the sensor comes back into range of a gateway receiver. Some sensors have store and forward capability where the cloud-based application can query the device to resend any missed packets.
Do the sensors support end-to-end communication with other sensors?
LoRaWAN class A devices operate in a hub and spoke architecture with the devices each communicating directly with a LoRaWAN gateway (the hub). This is not a mesh-type network.
Can I synchronize sensors?
LoRaWAN class A operation is based on unsynchronized, small packet uplinks to a gateway. It is a type of unslotted packet radio network.
How do I change device settings?
Yes, sensor settings can be configured using an appropriate downlink message sent by the application. Each sensor has a full set of documentation including a technical reference manual (TRM) that contains all required information for sensor configuration.
How far can I take a sensor from the GW?
LoRaWAN sensor range is highly dependent on the propagation environment that the sensor is in. In outdoor rural areas, ranges on tens of km are possible, in urban to suburban environments ranges of 1 to a few km are more typical. In indoor applications in multi-story buildings, it is helpful to have gateways provisioned indoors. Building construction (wood, concrete, etc.) also plays a significant role in defining sensor range indoors. For complex indoor deployments please contact TEKTELIC support for guidance.
How can I see my device data?
Device/Sensor data is typically viewed on an application that can be viewed on a web-page or mobile device app. TEKTELIC provides data converters to assist with formatting data as part of custom application development and TEKTELIC also provides custom applications for specific use cases. LeapX is a simple mobile app to get you started quickly in visualizing your data.
When does a sensor receive downlinks from the network server?
For class A LoRaWAN devices, the sensor receives downlinks in one of two defined receive windows after sending an uplink.
