Using experimental LoRaWAN address space in a production environnment

In LoRaWAN there is the concept of “address space”, where nodes on a network are assigned a particular address depending on the type of network server being used. This is described in this page of TTN.

The experimental space uses addresses starting with 0x00/0x01/0x02/0x03, which is what loraserver uses. Since these addresses are non-unique and they are validated using a MIC, collisions are avoided. What I am wondering is why there is a concept of address space in the first place. Does it even matter? Would it be a problem in the long term to use an “experimental” address space in production environment?


As far as I’m aware of, the prefix only matters for roaming. E.g. by looking at the prefix, the network-server is able to forward the data to an other network in case of a different prefix. See also the LoRaWAN Backend Interfaces specification.

So in theory, if one uses the experimental address space, loraserver can’t be used for a roaming system.
