LoRaWAN™ for Europe
LoRaWAN™ defines ten channels, eight of which are multi data rate from 250bps to
5.5 kbps, a single high data rate LoRa® channel at 11kbps, and a single FSK channel
at 50kbps. e maximum output power allowed by ETSI in Europe is +14dBM, with
the exception of the G3 band which allows +27dBm. ere are duty cycle restrictions
under ETSI but no max transmission or channel dwell time limitations.
LoRaWAN™ for North America
e ISM band for North America is from 902-928MHz. LoRaWAN™ defines 64,
125kHz uplink channels from 902.3 to 914.9MHz in 200kHz increments. ere are
an additional eight 500KHz uplink channels in 1.6MHz increments from 903MHz to
914.9MHz. e eight downlink channels are 500kHz wide starting from 923.3MHz
to 927.5MHz. e maximum output power in North America 902-928MHz band is
+30dBm but for most devices +20dBm is sufficient. Under FCC there are no duty
cycle limitations but there is a 400msec max dwell time per channel.
