Ubiquiti AF-24HD-US airFiber Wireless Bridge

Ubiquiti AF-24HD-US Wireless Bridge

Overview

The Ubiquiti AF-24HD-US is a high-capacity point-to-point wireless bridge designed for long-distance, high-throughput infrastructure deployments. Operating in the 24 GHz band, this airFiber model delivers 2 Gbps sustained throughput with 2 Gbps speed capability, making it suitable for backbone connectivity, campus interconnection, and remote site access where fiber is unavailable or cost-prohibitive. The AF-24HD-US is part of Ubiquiti's airFiber antenna product family and represents a proven platform for enterprise and carrier-grade wireless bridging.

Key Features

The AF-24HD-US provides enterprise-grade performance for managed infrastructure networks. Its 2 Gbps throughput enables reliable transport of multiple data streams, VoIP traffic, and video surveillance feeds across point-to-point links. The 24 GHz operating band offers a balance between range and bandwidth, with directional antenna gain that minimizes interference in dense deployment environments. The unit weighs 55 pounds, a consideration for tower-mounted installations requiring proper structural analysis and wind-load verification. Operating specifications and integration details align with Ubiquiti's broader airFiber ecosystem, supporting standard RF connectors and mounting hardware compatible with existing tower infrastructure.

Deployment Scenarios

The AF-24HD-US excels in scenarios requiring dedicated bandwidth between two fixed locations. Typical use cases include connecting remote office buildings to a main campus network, providing redundant backbone links for carrier networks, and establishing point-to-point bridges where latency-sensitive applications demand consistent performance. The unit is manufactured in CN and designed for outdoor deployment with appropriate weatherproofing and line-of-sight path planning. Distance capability depends on antenna alignment, atmospheric conditions, and Fresnel zone clearance.

Network Integration

Integration of the AF-24HD-US into existing networks requires careful frequency coordination, particularly in regions where 24 GHz spectrum is licensed. The bridge operates transparently as a Layer 2 device, requiring no complex routing configuration—endpoints simply connect as if linked by Ethernet. Network monitoring and management integrate with Ubiquiti's standard controller platforms, providing visibility into link performance, throughput utilization, and signal metrics.

Installation Notes

Installation requires precise antenna alignment, professional RF survey work, and structural load calculations for tower mounting. Proper grounding, surge protection, and PoE delivery infrastructure are essential for reliable operation. Pre-deployment site surveys should verify line-of-sight conditions and estimate fade margin under worst-case weather scenarios.

Jerry Tildsen, Senior Network Architect

"The Ubiquiti AF-24HD-US fills a clear role in wireless infrastructure when you need 2 Gbps throughput without the expense of fiber trenching. I've deployed several AF-24HD-US bridges at multi-building campuses, and the consistent performance justifies the tower work. Key lesson: budget for proper RF planning—poor antenna siting will waste the link's capacity regardless of equipment quality."
