Ubiquiti AF-5G34-S45 airFiber Wireless Bridge

Ubiquiti AF-5G34-S45 airFiber Wireless Bridge

Overview

The Ubiquiti AF-5G34-S45 is a dish-form airFiber wireless bridge designed for long-distance point-to-point connectivity in UISP Wireless deployments. This unit bridges network segments across challenging terrain or distances where fiber installation is impractical, delivering licensed or unlicensed 5 GHz spectrum performance in a rugged, weather-sealed enclosure. Manufactured in China and weighing 21 pounds, the AF-5G34-S45 integrates into existing Ubiquiti infrastructure for metropolitan area networks, campus interconnects, and service provider backhaul.

Key Features

The airFiber family delivers predictable, low-latency wireless bridging optimized for interference rejection in congested spectrum environments. The dish form factor provides directional gain and narrow beamwidth, reducing off-axis interference and improving link reliability over long distances. As a member of the UISP Wireless product line, the AF-5G34-S45 integrates with UISP management and orchestration platforms for centralized monitoring, firmware management, and network diagnostics. The bridge supports standard wireless protocols with robust link budget performance, making it suitable for outdoor point-to-point backhaul where GPS synchronization and carrier-grade reliability are expected.

Deployment Scenarios

Deploy the Ubiquiti AF-5G34-S45 to connect geographically separated network segments across 5+ kilometer distances where underground or aerial fiber is prohibitively expensive. Typical use cases include linking remote office campuses, extending managed network coverage across rural or urban areas, and establishing redundant backhaul paths for critical services. The wireless bridge model suits environments requiring rapid deployment without permanent infrastructure modifications.

Network Integration

The AF-5G34-S45 operates as a transparent Layer 2 bridge, requiring minimal network reconfiguration during integration. Configure the unit through Ubiquiti's web interface or UISP controller for monitoring, spectrum analysis, and link performance tracking. Align antenna pairs for optimal signal strength and verify line-of-sight clearance before deployment.

Installation Notes

Mount the dish antenna on a stable tower, pole, or building structure rated for the 21-pound weight and wind loading. Seal all cable penetrations with weatherproof connectors and silicone sealant. Power delivery and network connectivity route through a single cable run where possible to minimize weathering points. Confirm Fresnel zone clearance and avoid metallic obstructions within the radio path.

Marty Allison, Infrastructure Architect

"The AF-5G34-S45 is a straightforward, proven choice for integrators who need to extend wireless networks across medium distances without managing complex meshing or spectrum coordination. The dish form factor and UISP integration keep operational overhead low—the unit announces itself clearly on the network, and you can troubleshoot link problems from the UISP dashboard without serial console access. For teams running Ubiquiti infrastructure at scale, adding an AF-5G34-S45 feels familiar and cost-effective compared to point-to-point fiber."
