2.5 LoRaWAN
®
specification
For the data transfer from the model PGW23.100.11 measuring instrument, a radio
module with LoRaWAN
®
version 1.0.3. is used. The specification of the radio module can
be taken from the following table:

1) Spreading factors (graded between 7 ... 12) are automatically assigned according to the ambient conditions between the instrument
and the gateway. A higher SF increases the sending time and improves the communication range, though the energy consumption
of the instrument rises.
2) The range of frequencies in the radio frequency spectrum that is limited by a lower and an upper frequency. The frequency band shown
in the table is defined in the document published in 2019 by the European committee for radio communications (ERC).
3) The part of the frequency spectrum that should be used for the transmission.
4) Amount of energy transmitted to the antenna for communication. In Europe, the maximum sending power for the uplink is limited
to 25 mW (14 dBm).
5) The fraction of time in which an end device can occupy a channel. In Europe there is a duty cycle depending on the selected
channel of 0.1 % or 1 % per day.
6) The speed with which the data is transmitted. Dependent upon the bandwidth used and the spreading factor.
