Ubiquiti AF-5(US) airFiber Wireless Bridge

Ubiquiti AF-5(US) Point-to-Point Wireless Bridge

Overview

The Ubiquiti AF-5(US) airFiber Wireless Bridge is a dedicated point-to-point radio engineered for high-capacity wireless backhaul and bridge deployments across campus networks, remote site connectivity, and infrastructure links requiring 1.2+ Gbps throughput. This form factor delivers carrier-class performance in environments where fiber installation is impractical or cost-prohibitive. The AF-5(US) operates as a unidirectional or bidirectional link, making it suitable for both primary and redundant network paths in mission-critical deployments.

Key Features

The airFiber Wireless Bridge delivers 1.2+ Gbps throughput with efficient spectrum utilization optimized for long-distance point-to-point links. Operating as a dedicated point-to-point radio, the AF-5(US) eliminates the overhead and latency inherent in multi-user WLAN platforms, allowing integrators to architect predictable, high-performance backhaul. The compact form factor simplifies tower and rooftop mounting while maintaining robust mechanical construction suitable for outdoor deployment in varied climates.

Deployment Scenarios

The AF-5(US) excels in campus backbone applications, connecting multiple buildings across university grounds, corporate parks, and industrial facilities. Service providers leverage the platform for last-mile backhaul, remote site aggregation, and emergency recovery links. The 1.2+ Gbps capacity supports surveillance network aggregation, IoT hub interconnection, and data center replication without requiring trenching or fiber lease agreements. Integrators commonly deploy paired units for bidirectional operation over single or dual polarization configurations.

Network Integration

The AF-5(US) integrates into existing infrastructure via standard Ethernet interfaces, requiring minimal configuration changes to legacy systems. Point-to-point architecture eliminates the need for DHCP management or complex multicast handling, streamlining network topology and reducing administrative overhead. The bridge operates transparently at Layer 2, compatible with any routing protocol or network management stack. Redundancy strategies pair the AF-5(US) with secondary wireless or wired paths to meet availability requirements without architectural redesign.

Installation Notes

Weighing 52 pounds, the AF-5(US) requires appropriate tower or mast mounting hardware rated for wind loading in the installation geography. Direct line-of-sight between units is essential for optimal performance; obstructions significantly degrade throughput. Proper grounding and surge protection are mandatory given outdoor exposure and RF energy. Integration with existing tower infrastructure, cable management, and power delivery systems should follow site-specific engineering practices and local electrical codes. The MPN AF-5(US) should be clearly documented in asset management systems for lifecycle tracking and support correspondence.

Marty Allison, Infrastructure Architect

"The Ubiquiti AF-5(US) represents a practical solution for organizations needing reliable wireless backhaul without fiber deployment timelines. As a point-to-point radio, it trades user density for predictable, high-capacity links—exactly what backbone networks demand. The 1.2+ Gbps throughput handles multiple upstream aggregation scenarios, and the straightforward Ethernet integration minimizes operational complexity. For teams evaluating wireless backhaul, the AF-5(US) delivers solid performance at enterprise-friendly price points."
