UBNT airFiber AF5 Full Duplex 5Ghz Point to Point Configuration.

UBNT airFiber one of the best high throughput 11 ac Point to point wireless connectivity solution for telecom and local ISP. To get better performance and high-speed wireless connectivity you need to proper ubnt airfiber af5 point to point configuration with proper channel selection to avoid interference.

UBNT airFiber AF5 Point to Point Configuration with Full Duplex

UBNT is a well know name of Wireless Manufacturing industry. After Success Full point to point wireless device now producing CCTV camera, Network switch and long-range high throughput point to point Wireless solutions. Ubiquity Network claims 1.2+Gbps Throughput with 100+ KM Point to Point Wireless connectivity solution for AirFiber series. There are many good wireless solutions already performing good produced by airFiber with the low-cost product. UBNT especially design product for ISP and Telco,s. This post not confirming airFiber performance and distance with speed claiming by UBNT. This post is only for helping technical persons for ubnt airfiber af5 point to point configuration and describing basic features 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 the same devices. So you can plan airFiber with Different working mode supported by the airFiber series.

  1. ubnt airfiber af5 point to point configuration 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 nodes should be configured in the same mode at the 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

2: Ring Configuration:

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