Meshtastic is **not** LoRaWAN, nor TTN (TheThingsNetwork). Meshtastic uses the full spectrum frequency range designated to LoRa technology per region. This allows for several hundred possible frequency channels in the US region alone.

## Europe Frequency Bands
Power limits will generally be lifted in the software if `is_licensed` is set to `true` [HAM Mode](/docs/faq#amateur-radio-ham))
### 433 MHz
The maximum power allowed for Europe is +14dBm ERP ([Effective Radiated Power](https://en.wikipedia.org/wiki/Effective_radiated_power)).
The maximum power allowed for Europe is +14 dBm ERP ([Effective Radiated Power](https://en.wikipedia.org/wiki/Effective_radiated_power)).
The band range is from 433 to 434 MHz.
There are eight channels defined with a 0.2 MHz gap between them. Channel zero starts at 433.175 MHz
There are four channels defined with the standard radio preset `LongFast`. After factory reset the radio will be set to channel 3 with a center frequency of 433.875 MHz.
### 868 MHz (ISM Band)
### 868 MHz
The maximum power allowed for Europe is +27Bm ERP ([Effective Radiated Power](https://en.wikipedia.org/wiki/Effective_radiated_power)).
The maximum power allowed for Europe is +27 dBm ERP ([Effective Radiated Power](https://en.wikipedia.org/wiki/Effective_radiated_power)).
The band range is from 863 to 870 MHz.
The band range is from 869.40 to 869.65 MHz. This is less than the 863–870 MHz range defined as SRD Band, but allows for a higher ERP and a duty cycle of 10%.
There are eight channels defined with a 0.3 MHz gap between them. Channel zero starts at 865.20 MHz.
|Channel Number| Center Frequency|
|:---:|:---:|
| 10 |865.20 MHz|
| 11 |865.50 MHz|
| 12 |865.80 MHz|
| 13 |866.10 MHz|
| 14 |866.40 MHz|
| 15 |866.70 MHz|
| 16 |867 MHz|
| 17 |868 MHz|
There is one channel defined with the standard radio preset `LongFast`. After factory reset the radio will be set to channel 0 with a center frequency of 869.525 MHz.
## North America Frequency Bands
Power limits will generally be lifted in the software if `is_licensed` is set to `true` [HAM Mode](/docs/faq#amateur-radio-ham))
### 915 MHz (ISM Band)
The maximum output power for North America is +30 dBm ERP ([Effective Radiated Power](https://en.wikipedia.org/wiki/Effective_radiated_power)).
The band range is from 902 to 928 MHz.
There are thirteen channels defined with a 2.16 MHz gap between them. Channel zero starts at 903.08 MHz.
|Channel Number| Center Frequency|
|:---:|:---:|
| 00 |903.08 MHz|
| 01 |905.24 MHz|
| 02 |907.40 MHz|
| 03 |909.56 MHz|
| 04 |911.72 MHz|
| 05 |913.88 MHz|
| 06 |916.04 MHz|
| 07 |918.20 MHz|
| 08 |920.36 MHz|
| 09 |922.52 MHz|
| 10 |924.68 MHz|
| 11 |926.84 MHz|
| 12 |915 MHz|
There are 104 channels defined with the standard radio preset `LongFast`. After factory reset the radio will be set to channel 19 with a center frequency of 906.875 MHz.
