For reliable IQMESH traffic, every routing Zone must contain a sufficient number of discovered Nodes. A general rule is the more Nodes in a Zone, the better. It is especially important for the Zones closer to the Coordinator and crucial for Zone 0. Moreover, reliability depends on the RF signal quality. A strong signal without interferences may enable satisfying communication even with lower redundancy. However, this condition can usually not be guaranteed in the future, that is why the higher redundancy is a must.
Example:
A: Suspicious redundancy B: Almost none redundancy C: No redundancy at all
A: Insufficient number of Nodes in individual Zones. It works in a good environment.
B: But the same network will hardly work if the conditions get worse. Thus, the redundancy increasing is recommended even in case A above.
C: „Line Mesh“ with absolutely no redundancy. The first broken line disables all remaining Nodes.
Adding one or a few dedicated routers into lower Zones or a long-range antenna like AN-09 at the Coordinator may significantly increase the redundancy and bring other improvements (faster traffic and shorter building up the network).
