Overview
The Ubiquiti AF-5(US) is an airFiber 5 GHz Mid-Band wireless point-to-point bridge designed for long-distance network backhaul. It provides 1.2+ Gbps maximum throughput, 100+ km maximum range depending on regulatory region and frequency band, and GPS-based radio frame synchronization.
Wireless and Network Performance
The AF-5 operates in the 5 GHz mid-band with regional frequency ranges extending from 5470 MHz to 5950 MHz. It supports channel bandwidths from 10 MHz through 50 MHz and modulation modes up to 1024QAM MIMO. The integrated radio uses dual-slant polarization with 23 dBi transmit and receive gain and a 6° beamwidth.
Key Features
- 1.2+ Gbps maximum point-to-point throughput
- 100+ km maximum range, dependent on regulatory region and frequency band
- 10/20/30/40/50 MHz channel bandwidth support
- GPS synchronization for radio frame timing
- 128-bit AES encryption and dual-slant polarization
Interfaces and Power
The bridge provides one Gigabit Ethernet RJ45 port, one 10/100 Mbps Ethernet management port, and an RJ-12 auxiliary alignment-tone port. It uses passive PoE over four pairs and operates from 42–58 V DC. A 50 V, 1.2 A Gigabit PoE adapter is included, with maximum power consumption rated at 40 W.
Mounting and Deployment
The AF-5 includes a pole-mount kit and is rated for wind survivability of 200 km/h, with wind loading specified at 863 N at 200 km/h. Operating temperature is -40°C to 55°C. The unit includes local and remote calibrated signal-strength displays and status LEDs for network, GPS, master/slave, link, modulation, and overload conditions.
DC Supplies Product Note
For deployment planning, the AF-5 is the mid-band version of the airFiber 5 platform. The high-band AF-5U is a separate model with different regional frequency ranges, so the exact model and applicable regulatory band should be verified before deployment.
