The USA LoRaWAN frequency spectrum has 64 uplink channels available (125 kHz each) (channels 0-63) starting at 902.3 MHz which increment every 200 kHz up to 914.9 MHz.
There are 8 additional uplink channels (500 kHz each) (channels 64-71) from 903 MHz which increment every 1.6 MHz up to 914.2 MHz.
For gateway to end-node device communication, there are 8 downlink channels (500 kHz each) (channels 0-7) from 923.3 MHz which increment every 600 kHz up to 927.5 MHz.
For 8 channel gateways:
The Things Gateway from The Things Network (TTN) also uses Sub-Band 2 for LoRaWAN communication as listed in the following link: https://www.thethingsnetwork.org/docs/lorawan/frequency-plans.html#us902-928
Laird Sentrius RM191 gateways will default to sub-band 2. They can be reconfigured, if required as instructed in the Channel Masking section of the RM1xx LoRa smartBASIC Extensions guide for Laird LoRaWAN gateways on page 14.
Multitech gateways are configured by selecting one of the 8 channel sub-bands as shown in the table, each containing eight 125kHz uplink channels and one 500kHz downlink channel.
LORIX One IP65 outdoor gateway can operate from -30°C to +55°C and can be found at the following link: https://www.lorixone.io/en/products
All 8 downlink channels should be enabled on commercially available gateways.
MeteoHelix weather station.
Gateways or LoRa application server like The Things Network, Loriot, Loraserver.io and others, govern which frequency sub-band you need to use. USA, Canada, Mexico, Brazil and Australia LoRaWAN version MeteoHelix IoT Pro micro-weather stations feature the ability to turn-on and off different uplink broadcast channels via a downlink command as shown in the following List of available downlink commands for MeteoHelix LoRaWAN weather stations.
BARANI DESIGN Technologies MeteoHelix weather stations default to Sub-Band 2 when reset using a magnet placed next to the filter cap.
The “All Bands” option (not selecting a sub-band) may be used if you don’t know the configuration of a gateway. This will result in a one in eight chance of the gateway connecting with an end-node device since each gateway only supports 8 out of the available 64 uplink channels in the USA LoRaWAN frequency band.
