In addition to the simple Point-to-Point (PtP) link design, the airFiber 24 (AF24) can be used in ring edundancy patterns as well as daisy-chained paths, as shown below.
Ring Redundancy
Multiple AF24 radios can be placed in a ring-topology for redundancy. If one link goes down, other links have alternate routes available. For each link, configure one airFiber radio as Master and the other as Slave.

Daisy-Chain Paths
Multiple AF24 radios can also be used to extend the distance of a link like a series of PtP relays (PtPtP). Radios in the same node must use the same Wireless Mode (Master or Slave) to ensure low-latency across the entire link.
