1.3 | 26 | In the gateway, there are two radios: (% style="color:#037691" %)**Radio0** (% style="color:black" %)and (% style="color:#037691" %)**Radio1**.(% style="color:black" %) We can configure the frequency at the (% style="color:#037691" %)**±400000hz **(% style="color:black" %)range base on these two Radios. In this case, we can set: (% style="color:#037691" %)**Radio0 = 865700000** (% style="color:black" %)and(% style="color:#037691" %)** Radio1 = 866500000**.(% style="color:black" %) And the eight frequency we need are: |

1.1 | 27 | |
| |
1.2 | 28 | * Channel 0 frequency = radio0 – 300000Hz = 865700000 - 300000 = 865.4 Mhz |
| 29 | * Channel 1 frequency = radio0 – 100000Hz = 865700000 - 100000 = 865.6 Mhz | ||
| 30 | * Channel 2 frequency = radio0 + 100000Hz = 865700000 + 100000 = 865.8 Mhz | ||
| 31 | * Channel 3 frequency = radio0 + 300000Hz = 865700000 + 300000 = 866.0 Mhz | ||
| 32 | * Channel 4 frequency = radio1 - 300000Hz = 866500000 - 300000 = 866.2 Mhz | ||
| 33 | * Channel 5 frequency = radio1 - 100000Hz = 866500000 - 100000 = 866.4 Mhz | ||
| 34 | * Channel 6 frequency = radio1 + 100000Hz = 866500000 + 100000 = 866.6 Mhz | ||
| 35 | * Channel 7 frequency = radio1 + 300000Hz = 866500000 + 300000 = 866.8 Mhz | ||
| 36 | * Channel LoRaSTD frequency= 865.7Mhz, SF7, BW250Khz | ||
