Ubiquiti Bullet Dual-Band AC (B-DB-AC)

The Ubiquiti Bullet Dual-Band AC (B-DB-AC) is a powerful, plug-and-play radio designed to transform any compatible antenna into a robust, dual-band wireless access point or station. As part of Ubiquiti’s airMAX lineup, the B-DB-AC combines high-performance 2.4 GHz and 5 GHz capabilities into a single, durable unit, enabling flexible deployments in point-to-point (PtP) and point-to-multipoint (PtMP) wireless applications. Engineered with the needs of wireless ISPs (WISPs) and system integrators in mind, it provides an ideal solution for building cost-effective, scalable, and efficient outdoor wireless networks.

What sets the Bullet B-DB-AC apart is its seamless integration with standard N-type connector antennas. This allows for rapid deployment across a variety of antenna types and gain levels, depending on coverage needs and environmental conditions. By attaching directly to the antenna, the Bullet minimizes signal loss from cables and ensures a clean, powerful RF path, delivering superior performance in both 2.4 GHz and 5 GHz frequency ranges.

The B-DB-AC supports 802.11ac Wi-Fi technology, enabling dual-band performance of up to 300 Mbps on 2.4 GHz and 867 Mbps on 5 GHz. This dual-radio capability allows network administrators to serve legacy devices on 2.4 GHz while maintaining high-throughput links on the cleaner and less congested 5 GHz band. The unit automatically selects the best frequency based on environment and usage, enhancing performance and reducing interference.

Durability is a core strength of the Bullet B-DB-AC. Built with a weather-resistant aluminum enclosure and UV-resistant casing, the unit is IP67-rated, ensuring long-term operation in harsh outdoor conditions. Whether mounted on towers, rooftops, or masts, the Bullet is designed to handle wind, rain, heat, and cold without compromising its performance. Its compact and cylindrical form factor makes installation straightforward, while the integrated LEDs offer easy signal strength and power status at a glance.

The Bullet B-DB-AC is powered via 24V passive PoE, allowing a single Ethernet cable to provide both data and power. This simplifies cabling and reduces deployment complexity, especially in remote locations. The device is managed using Ubiquiti’s airOS software, which provides intuitive web-based controls, signal statistics, throughput monitoring, and advanced configuration options. It is also compatible with the UISP platform for centralized network management.

In summary, the Ubiquiti Bullet Dual-Band AC (B-DB-AC) is a versatile, high-performance outdoor radio designed for flexible integration with antennas of various types and sizes. Offering dual-band 802.11ac wireless, durable weatherproof housing, and robust airMAX support, it’s an excellent choice for custom outdoor wireless deployments requiring strong throughput, reliability, and scalability.
