WHAT IS LoRaWAN™?
Network Architecture
Many existing deployed networks utilize a mesh network architecture. In a mesh
network, the individual end-nodes forward the information of other nodes to
increase the communication range and cell size of the network. While this increases
the range, it also adds complexity, reduces network capacity, and reduces battery
lifetime as nodes receive and forward information from other nodes that is likely
irrelevant for them. Long range star architecture makes the most sense for preserving
battery lifetime when long-range connectivity can be achieved.
