Regional Parameters

Hi All,

Am a bit confused regarding the Regional Parameters in the Device profile. It states that it can be set to A or B, but what does A or B mean?

I have devices with loraWAN 1.0.2 MAC version and no idea what to set the Regional Parameters to. The Device is an 868Mhz freq.

I have read the LoRaWAN specification and it states the following:


This seems confusioning as the table suggests any LoRaWAN 1.0.2 devices should be B.

Is this correct?

Thanks
Gary

The Regional Parameters are region specific values which are defined outside the LoRaWAN specification. Examples are the defined channels, max payload sizes, data-rate to spreadingfactor/bandwidth mapping, tx power mappings etc… These might be updated over time independent of the LoRaWAN MAC version.

You will find these specifications at: https://lora-alliance.org/resource-hub.

Hi Brocaar,
Thanks for the link.

I have read through the spec somewhat, but can’t make the link to A or B on the GUI.

Can you point me in the direction of GUI docs that explained these options and other options on the page.

Sorry for any inconvenience.

Gary

You can configure this in the Device Profile.

But what does ‘A’ mean and what does ‘B’ mean? I cannot find any reference to these either.

They are part of the version number. For example:

https://lora-alliance.org/resource-hub/lorawanr-regional-parameters-v102rb

1.0.2 revision B

I’d also like to get this straight. Is the following correct?

Each LoRaWAN version attempts to make it possible to adhere to the latest Regional Parameters, which are set by law in their respective regions. These Regional Parameters are described in documents released by the LoRa Alliance, which have names like, for example, v1.02rB, which in this case would indicate that in order to adhere to the Regional Parameters described in that document, you must (?) use LoRaWAN v1.02 and use your devices according to the Regional Parameters in that revision of the specification, in this case B.

So it is the responsibility of the End-node user to use the devices in adherence to the Regional Parameters, which involves stuff like not exceeding payload size, duty cycles, etc.

If this is correct, then why do we need to specify the revision in the Device profile? Does the Application Server have some mechanism to help enforce adherence to the Regional Parameters?

The device profile configures operation according not just to regional parameters, but to the LoRaWAN spec. The network server operates different depending on version. 1.0.3 vs 1.1 significantly, 1.0.2 vs 1.0.3 subtly (potentially), etc.
