### spread_factor
|
|
|
|
LoRa is a spread spectrum technology. spread_factor is how much the signal is spread over the spectrum. SF8 = 2^8 or spread 256 times. SF12 = 2^12 or spread 4096 times.
|
|
|

### tx_power
|
|
|
|
Configured transmit power out of the LoRa radio, measured in dBM. Setting this to `0` will use the device default which is the max legal continuous power for your region.
|
|
|
|
:::caution
|
|
Ensure that you are not exceeding your country's regulations.
|
|
|
|
`Country regulation - antenna gain = tx_power max setting`
