... using two Gateways

[zzz-teo]

@gohan ...to have a wired backbone in a bigger vertical installation, each level has a repeater for level wireless connectivity.

I guess at the moment you can only use repeater nodes and or use longer range radio modules

@gohan
... yes this is the only solution ... but using long range modules the network is exposed to neighborhoods and may someone be motivated to play with it!
By using RS485 backbone the exposed level is reduced. (as well as EMI exposure).
... and by using repeaters may not be stable due to area division by Slabs.

That's why encryption and signing have been invented 😁
