biquiti Networks AF-5 Overview

Operating on the 5 GHz frequency band, the AF-5 airFiber Mid-Band 5 GHz Carrier Class Point-to-Point Gigabit Radio from Ubiquiti Networks offers point to point connectivity at long distances of over 62 miles (100 kilometers). This enhanced coverage provides a reliable backhaul connection which is an essential part of many building-to-building enterprise network configurations. With a dual-antenna architecture, 2×2 MIMO functionality separates the transmit and receive data streams allowing for increased bandwidth and a more reliable connection. Setup of this PtP Gigabit radio is simple thanks to the airFiber Configuration Interface which can be installed by a single network tech. Once installed, 12 dedicated LED indicators make it easy to see the status of various aspects of the network including data port link/activity, data port speed, management port link/activity, and much more.

Wireless Technology
  • Point-to-point wireless platform
  • Housed in a compact, highly efficient form factor
  • Delivers wireless gigabit+ performance with low latency
  • xRT feature uses an adaptive multi-channel coding scheme to enhance radio transceiver performance, while still maintaining regulatory compliance
  • Supports long range communication up to 62+ miles
  • Operates in license-free, mid-band 5 GHz frequencies
  • Worldwide license-free operation
  • Delivers gigabit performance at 1.0+ Gb/s
  • Suitable for carrier backhaul, building-to-building enterprise use, or public safety applications
Synchronous Data Transmission and Reception
  • Transmits data synchronously without any wait time
  • Uses traditional TDD and FDD modes of operation
  • Features the proprietary Hybrid Division Duplexing (HDD) mode for long range and spectral efficiency performance
  • HDD technology calculates the propagation delay for synchronous transmissions and eliminate packet transmission latency
  • Based on the ranging algorithm built into the air protocol
Dual-Antenna Architecture
  • Features a dual-independent, 2×2 MIMO, high-gain reflector antenna system
  • Separate transmit and receive antennas eliminates the extra RF losses caused by the switches or duplexers
  • Includes a mechanical back‑plane that is constructed as a one-piece monocoque molding
  • Single‑piece, injection‑molded architecture
Network Management
  • Network management option between the greater security of out‑of-band management and the convenience of in-band management
  • Full SNMP support for network management
  • Local and remote status information available on the main tab of the airFiber configuration interface
  • Proprietary INVICTUS core communications processing engine
  • Features 1 MHz center channel resolution with Power Envelope Tracking technology
  • Accurately and continuously controls transmit power relative to the band edge
  • Power level automatically tracks to optimize performance near band edges, allowing you to choose the part of the band with the least interference
Radio Alignment Display
  • Radio Alignment Display (RAD) makes aiming quicker and easier
  • Dual, calibrated signal strength indicators display the actual signal strength on the local and remote airFiber radios in real time
  • Displays information about GPS synchronization status, master/slave mode, RF link status, RF overload warning, current modulation mode, and link activity and speed for wired management and data ports
  • Based on Ubiquiti’s airOS
  • Enables quick deployment
  • Sliding-clamp design allows mounting hardware to be pre‑assembled prior to installation
  • Drop‑in cradle mount design allows the installer to attach mounting hardware to the pole without having to support the weight of the airFiber radio during installation
