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-known name of the Wireless Manufacturing industry. After Success Full point-to-point wireless devices now producing CCTV cameras, Network switches, 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 the AirFiber series. There are many good wireless solutions already performing well produced by airFiber with the low-cost product. UBNT especially designs products for ISPs and Telco,s. This post not confirming airFiber performance and distance with speed claimed by UBNT. This post is only for helping technical persons for ubnt airfiber af5 point to point configuration and describing the basic features of 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 modes supported by the airFiber series.

  1. ubnt airfiber af5 point-to-point configuration Connectivity

In point-to-point connectivity, two airFiber radios will be configured. One airFiber radio will be configured with Master mode for Location A and the Second airFiber radio will be in slave mode for Location B

AirFiber Point to Point configuration Manual

1: Daisy Chain :

A Daisy chain is nothing but used like a 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 the daisy chain radio must be configured in master mode. See the below picture to understand clearly.

What is Daisy Chain in airFiber Radio

2: Ring Configuration:

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