8 Transfer measured values and data to the cloud
VEGAPULS Air 41 • Autarkic device with measured value transmission via radio technology
64808-EN-210426
8 Transfer measured values and data to the
cloud
8.1 Communication basics
To transmit the measured values and data to the cloud, the device
requires access to mobile network or a LoRaWAN network at the in-
stallation site, depending on the version. If no corresponding network
is available, a LoRaWAN gateway must be installed.
Note:
Ensure free access to the radio network. The device must not be
covered by metal or even enclosed. This especially for the medium
height of the housing.
Note:
Simultaneous operation of LTE-M or LTE-IoT and LoRaWAN is not
supported.
The following measured values or data are transmitted:
•
Distance from the medium surface (m)
•
Electronic temperature (°C)
•
Geographical position determined by GNSS (geographical coor-
dinates)
•
Mounting position (angle °)
•
Remaining life of Lithium cells (%)
•
Device status
The transmission options are described below.
8.2 NB-IoT/LTE-M - VEGA Inventory System
With NB-IoT (Narrow band Internet of Things) and LTE-M (Long
Term Evolution for Machines), the focus is on low data rates and high
transmission ranges. Another focus is on penetrating propagation
obstacles, such as buildings, for which the long-wave signal is well
suited.

VEGA Inventory System
Data is sent via an eSIM card integrated in the sensor. This card
sends the data via mobile network directly to the VEGA Inventory Sys-
tem. If no mobile network is available, a fallback to LoRa takes place
automatically (see below).
