Overview
The Ubiquiti AF-5U is an airFiber 5 High-Band wireless point-to-point bridge designed for long-distance network backhaul. It operates in the 5.7–6.2 GHz high-band spectrum and provides 1.2+ Gbps maximum throughput, 100+ km maximum range, and GPS-based radio frame synchronization. The AF-5U also incorporates filtering intended to support co-location with equipment operating in lower 5 GHz bands.
Wireless Performance
The AF-5U supports regional operating ranges from 5725–5850 MHz under FCC/IC requirements, 5725–5875 MHz under ETSI requirements, and up to 5725–6200 MHz in other regions. Channel bandwidths of 10, 20, 30, 40, and 50 MHz are supported, with modulation up to 1024QAM MIMO. The radio provides 23 dBi transmit and receive gain, a 6° beamwidth, dual-slant polarization, and greater than 28 dB cross-polarity isolation.
Key Features
- 1.2+ Gbps maximum throughput for point-to-point backhaul
- 100+ km maximum range, dependent on regulatory region
- High-band operation from 5725 MHz with regional support up to 6200 MHz
- GPS radio frame synchronization with programmable uplink/downlink ratio in Half Duplex mode
- 128-bit AES encryption and 1+ million packets-per-second processing
Interfaces and Power
The AF-5U provides one Gigabit Ethernet RJ45 data port, one 10/100 Mbps Ethernet management port, and an RJ-12 auxiliary alignment-tone port. It uses passive four-pair PoE with a supported voltage range of 42–58 V DC. A 50 V, 1.2 A Gigabit PoE adapter is included, and maximum power consumption is 40 W.
Mounting and Environmental Specifications
The pole-mount kit is included. The radio measures 938.4 × 468.4 × 281.4 mm and weighs 16 kg with the mount. Ubiquiti specifies wind survivability of 200 km/h and wind loading of 863 N at 200 km/h. The operating temperature range is -40°C to 55°C.
DC Supplies Product Note
The AF-5U is the high-band member of the airFiber 5 platform. Unlike the AF-5 mid-band model, the AF-5U is designed for the 5.7–6.2 GHz high-band spectrum. Frequency availability and permitted output power depend on the country and applicable regulatory requirements, so deployment should be configured for the local regulatory domain.
