NUCLEO-WL55JC Distance Range

[EmdSTM32WL]

Hello ST Expert ,

I'm using the NUCLEO-WL55JC1 for my project as Gateway and End-device.

I have one Gateway and 4 end device ( based on the same baord ) , i don't made any hardware change , and I'm using the SW delivered by STMicroelectronics.

I have an issue for the distance range between the Gateway and the End device.

I'm using the same configuration in all boards ( gateway and end-devices )

- SF = 11 ; Freq = 125Khz

- 22dbi

=> The maximum range is 100 metres 

So ,I changed the Antenna  I had 300 meters..but it is not enough for my projects.

At least i want 1000 metres to connect all End device.

Any Suggestion please I'm very blocked

Best Regards

Hello everyone, I'm joining this thread because I'm experiencing some similar issues. I have 2 Nucleo WL55JC2 communicating via LoRa raw at 433MHz. I've already optimized dbm (maximum allowed), SF (7) and BW(500) but I can't still reach my 1.5/2 km target of range and consider that i have a constraint of maximum 100ms of latency. At now the range is around 600m. Do you have some suggestions or could it be the limit with the standard antenna?
