This post not confirming airFiber performance and distance with speed claiming by UBNT. This post is only for helping technical person for AirFiber AF5 Point to Point configuration and describing basic feature about air Fiber Series.AirFiber5 means 5Ghz band and AirFiber 24 mean 24Ghz band which device working frequency for wireless connectivity.


airFiber AF5 and AF5u series working mode for Link Planning.

Although airFiber AF5 and AF5u both are same device. So you can plan airFiber with Different working mode supported by airFiber series.

  1. Point to Point Connectivity:

In point to Point connectivity two airFiber radio will be configured. One airFiber radio will configure with Master mode for Location A and Second airFiber radio will be in slave mode for Location B

  1. Daisy Chain :

Daisy chain is nothing but used like  relay for extending a Point to Point link to increase the distance. In this mode both node should be configured in same mode at same location. Exp: if location A configured with Master then daisy chain radio must be configured in master mode. See below picture to understating clearly.

What is Daisy Chain in airFiber Radio

  1. Ring Configuration:

Ring is stand for a redundant wireless path to avoiding network down depending on single point to point connectivity. In Ring use multiple radio to create a ring path if one path will down then network will connected through other path without goes down. One AirFiber radio will configure as Master and second configure as Slave.
