Hello, I was searching for the range ( in meters or Kilometers) of the STM32WLE5xx/ STM32WLE4xx ?? I couldn't find the information in the datasheet. Thanks for your help.

OK, now at least some parameters are given so that you can achieve ranges between 10...20km, when used with an appropriate antenna. Depending on the environmental conditions, other ranges are also possible. Also, you must not forget that the data rate plays a major role: for the 10...20km mentioned with LoRa, that is about 200bit/s.

Welcome, @AYous.3, to the community!

Of course, you cannot find any information on this in the data sheet. Even if the range is specified for a finished module, i.e. a complete radio system including antenna, this always applies under certain conditions. The range of a radio system and thus also of a system based on STM32WLE depends on many factors:

transmitting power, input sensitivity (both together called link budget),
antenna gain (determined by the antenna geometry, among other things),
modulation method,
attenuation of the objects lying between transmitter and receiver (walls, trees, mountains,...),
etc.

Does it answer your question?

It might be helpful to know what you actually want to achieve so that someone can help you.

Regards

/Peter

@Peter BENSCH Thanks for your help,

I'm not looking for a specified information because I know that It depends on many parameters. But I wanted to know approximately the range of this transceiver, in an open area for example with a 14 dBm as an output power using LoRa.

Depends on a lot of factors.

15 km LoS should be demonstrable, perhaps 30 km LoS with effort and suitable conditions/terrain. Vertically perhaps to the edge of space.
