Traditional LoRaWAN is based on a star topology rather than a mesh (I say traditional as there are P2P and mesh flavors of LoRa now available). OP mentioned wanting to retain network functionality in the event that the network gateway goes down which would rule out LoRa / star network topologies.
- 3np 5y agoIs this something inherent in the protocol making it less suitable for mesh applications or simply convention and lack of implementation? Do the mesh flavors require new hardware?
- namibj 5y agoLoRa gets part of its efficiency from fairly brutal sleeping, to the point where the radio would only get turned on to transmit when sensor data meaningfully changed or some (weeks) timeout comes up to say "yes, I'm still alive". Also, it's range being longer than normal mobile phone cellular radio allows getting away with sparingly-positioned gateways. Also it's not truly star, but rather gateways vs. nodes (at least with the popular LoRaWAN stuff). All gateways that pick up a node's transmission will report it to central servers.
