Hi

in data sheet of different stm32WB modules, i see that max Output Power (dBm) is +6.

Why is it 6 and not 8? I thought for europe the limit is 8?

In case I want to sell the devices IN USA, max  allowed TX power is even +20dbm. Does ST have any module with +20dBm?

and one generic question: I am building a wearable measuring some medical data(EMG data). Is there any standard putting a limit on TX power? Or can I go with +6 dBm?

thx

Hello @MK..1 

Maximum output power on the STM32WB is 6 dBm. The limitations on the Maximum TX power is limited only by the low of each country.

Best Regards.
