Document ETSI compliance on docs/devices/open-source-hardware/nrf52840-series/mesh-tower/Usage.md #13

Description

@monty241

The mesh tower comes with an antenna "N-interface fiberglass antenna 5.5dBi", directly attached to the device.

The specifications state:

LoRa Transmit Power: 21 ± 1 dBm

Are the standard settings such that ETSI regulations are met? Or to what value should they manually be changed to meet regulations?

Without further technical knowledge, I would come to effective raditioaon of 21 dBm + 5,5 antenna gain - 0 or little cabling - 2,15 > 14 dBM ERP.

For compliance, does reducing transmit power by 10 dB suit the regulations? And is that possible in the user interface to set?
