This charpter shows how to customized the frequency bands for the LoRaWAN gateway. Support below models:

2. Configuration Step by Steps

2.1 Determine the frequency band to be set

For example, we want to set the gateway to work for below frequency band

Determine what is the frequency to be used

2.2 Find suitable centra frequency

In the gateway, there are two radios: Radio0 and Radio1. We can configure the frequency at the ±400000hz range base on these two Radios. In this case, we can set: Radio0 = 865700000 and Radio1 = 866500000. And the eight frequency we need are:

  • Channel 0 frequency = radio0 – 300000Hz = 865700000 - 300000 = 865.4 Mhz
  • Channel 1 frequency = radio0 – 100000Hz = 865700000 - 100000 = 865.6 Mhz
  • Channel 2 frequency = radio0 + 100000Hz = 865700000 + 100000 = 865.8 Mhz
  • Channel 3 frequency = radio0 + 300000Hz = 865700000 + 300000 = 866.0 Mhz
  • Channel 4 frequency = radio1 - 300000Hz = 866500000 - 300000 = 866.2 Mhz
  • Channel 5 frequency = radio1 - 100000Hz = 866500000 - 100000 = 866.4 Mhz
  • Channel 6 frequency = radio1 + 100000Hz = 866500000 + 100000 = 866.6 Mhz
  • Channel 7 frequency = radio1 + 300000Hz = 866500000 + 300000 = 866.8 Mhz
  • Channel LoRaSTD frequency= 865.7Mhz, SF7, BW250Khz
