Ubiquiti PowerBeam 5AC-400

The Ubiquiti PowerBeam 5AC-400 is a cutting-edge wireless bridge engineered to provide high-speed connectivity over long distances. Designed with Ubiquiti's proprietary airMAX AC technology, this device ensures superior performance, reduced latency, and enhanced noise immunity. Its integrated 25 dBi antenna and 5 GHz radio make it an excellent choice for high-bandwidth applications, such as video streaming, VoIP, remote surveillance, and data transmission.

This article provides an in-depth exploration of the PowerBeam 5AC-400, including its features, specifications, benefits, applications, setup process, and troubleshooting tips.

2. Key Features of the Ubiquiti PowerBeam 5AC-400

a. airMAX AC Technology

The PowerBeam 5AC-400 utilizes airMAX AC, which optimizes time division multiple access (TDMA) for improved performance and efficiency. This ensures:

• Lower latency for real-time applications
• Higher throughput (up to 450+ Mbps)
• Better spectral efficiency

b. Integrated 25 dBi High-Gain Antenna

The PowerBeam 5AC-400 features a 400 mm (15.75-inch) dish antenna with a 25 dBi gain, which enhances long-range connectivity. This makes it an excellent choice for establishing long-distance point-to-point (PtP) links or connecting remote locations in point-to-multipoint (PtMP) setups.

c. Innovative RF Isolation and Noise Immunity

Thanks to its parabolic reflector and optimized beamwidth, the PowerBeam 5AC-400 minimizes interference from other radio sources, ensuring stable connections even in noisy RF environments.

d. Compact and Lightweight Design

Unlike traditional wireless bridges that require separate radios and antennas, the PowerBeam integrates both into a single compact unit, reducing setup complexity and improving wind resistance.

e. Durable and Weatherproof Build

The device is engineered for outdoor use and can withstand harsh weather conditions, including rain, snow, and extreme temperatures.

f. Easy Deployment and Installation

With an intuitive mounting system, the PowerBeam 5AC-400 allows for quick and secure installation on poles or walls. It also supports remote configuration via Ubiquiti’s intuitive airOS interface.
