Ubiquiti Bullet DB-AC Series
Zero-Variable Wireless Outdoor airMAX Radio

Overview:

Ubiquiti Networks designed airMAX® ac radios for high performance and ease of installation. You have the freedom to deploy the Bullet ™ AC anywhere in the world, as it allows for a high degree of flexibility in configuring channel bandwidths (subject to local country regulations).

Zero-Variable Deployment

The Bullet AC eliminates the need to use RF cables and requires no special antenna or tools to install. No radio card / host board issues. No RF cable quality concerns. No mechanical stability concerns. No enclosure mounting requirements. With the Bullet AC, operators can just plug and go.

Technology

Unlike standard Wi-Fi protocol, Ubiquiti’s Time Division Multiple Access (TDMA) airMAX ac protocol allows each client to send and receive data using pre-designated time slots scheduled by an intelligent AP controller.

This time slot method eliminates hidden node collisions and maximizes airtime efficiency, so airMAX ac technology provides performance improvements in latency, noise immunity, scalability, and throughput compared to other outdoor systems in its class.

Intelligent QoS Priority assigned to voice/video for seamless streaming.

Scalability High capacity and scalability.

Long Distance Capable of high‑speed, carrier-class links.

Superior Performance

The next-generation airMAX ac technology boosts the advantages of our proprietary TDMA protocol.

Ubiquiti’s airMAX engine with custom IC dramatically improves TDMA latency and network scalability. The custom silicon provides hardware acceleration capabilities to the airMAX scheduler, to support the high data rates and dense modulation used in airMAX ac technology.

Throughput Breakthrough

airMAX ac supports high data rates, which require dense modulation: 256QAM – a significant increase from 64QAM, which is used in airMAX.

With their use of proprietary airMAX ac technology, airMAX ac products supports up to 500+ Mbps (maximum 80 MHz channel width) real TCP/IP throughput – up to triple the throughput of standard airMAX products.

Features:

Dual-Band Frequency The Bullet AC covers both 2.4 and 5 GHz spectrums, covering a wide range of frequency bands that work well for both short and long-distance links.

Passive Power over Ethernet (PoE) 24V Passive PoE functionality is included. Both power and data are carried over a single Ethernet cable to the Bullet AC. Use the included PoE Adapter or an optional PoE switch.

Output Power The Bullet AC offers up to 22 dBm of output power.

Weatherproof Design The Bullet AC features a weatherproof design. Made from a high-grade, powder-coated aluminum, the casing can withstand nature’s harshest outdoor elements
