Ubiquiti PowerBeam M5 400 High-Performance 5GHz airMAX CPE Bridge

Introduction

The Ubiquiti PowerBeam M5 400 is a powerful 5GHz airMAX bridge designed for high-performance outdoor wireless networking. Engineered as a customer premises equipment (CPE) device, the PowerBeam combines a focused directional antenna with Ubiquiti’s advanced airMAX and InnerFeed technologies to deliver robust, long-distance point-to-point and point-to-multipoint connectivity.

With superior noise immunity, intelligent QoS, integrated radio design, and centralized network management tools, the PowerBeam M5 400 is ideal for wireless ISPs, rural internet delivery, and enterprise outdoor networking across New Zealand.

Key Features & Benefits

Focused RF Energy for Maximum Noise Immunity

The PowerBeam M5 400 uses a narrow beamwidth to direct RF signals precisely toward the target device. This focused transmission:

• Filters out external RF interference

• Improves signal clarity in noisy wireless environments

• Enhances performance in congested frequency areas

Integrated InnerFeed™ Design for Signal Efficiency

With Ubiquiti’s proprietary InnerFeed™ technology, the radio is built directly into the feedhorn of the antenna eliminating the need for external cabling. This leads to:

• Reduced signal loss

• Faster installation

• Increased durability and reliability

airMAX TDMA Protocol for High-Speed, Scalable Networking

The PowerBeam supports Ubiquiti’s airMAX protocol, which uses Time Division Multiple Access (TDMA) to assign time slots to each connected device. This dramatically reduces hidden node collisions and enhances:

• Latency performance

• Network throughput

• Scalability for multiple clients

Intelligent QoS ensures that video and voice traffic receive priority, making it suitable for streaming and VoIP applications.

User-Friendly airOS Firmware

The built-in airOS firmware makes configuration easy with:

• Multi-language support

• Protocol and channel control

• Spectral width adjustment

• ACK auto-timing

• AAP (Advanced ACK Processing) technology

This high-performance firmware is optimized for long-range outdoor multi-point networking.

airView Spectrum Analyzer

Integrated into all M-series devices, airView gives you real-time and historical spectrum analysis through:

• Waterfall view – visualize signal energy over time

• Waveform view – display aggregated energy data

• Real-time spectral view – see live frequency usage
  Operators can also automate airView recording and reports to aid in network planning and interference avoidance.

airControl – Centralized Network Management

airControl is a web-based application that allows users to centrally manage large deployments of Ubiquiti devices. Key features include:

• Network mapping

• Device status monitoring

• Mass firmware upgrades

• Group management and task scheduling

• Remote Web UI access
