Ubiquiti PowerBeam M5 400 (PBE-M5-400)
The PowerBeam M5 400 is a high-performance outdoor wireless bridge from Ubiquiti Networks, designed for long-range point-to-point (PtP) and point-to-multipoint (PtMP) applications.
Key Specifications
- Frequency: 5 GHz (5150-5875 MHz)
- Antenna Gain: 25+ dBi
- Range: Up to 30+ km (line of sight)
- Throughput: Up to 150+ Mbps real-world performance
- Beam Width: Approximately 7 degrees (narrow focused beam)
- Power: 802.3af PoE or 24V passive PoE (adapter included)
- Mounting: Integrated precision mounting system
Features
Compact Integrated Design – The dish antenna and radio are built into one weatherproof unit, making installation straightforward.
airMAX Technology – Ubiquiti’s proprietary TDMA protocol provides superior performance in noisy RF environments and scalable point-to-multipoint deployments.
InnerFeed Technology – Improves beam directivity and reduces side lobes for better overall performance and noise immunity.
Built-in AirOS – Web-based management interface with spectrum analyzer, throughput testing, and link modeling tools.
Common Use Cases
- ISP backhaul links between towers or buildings
- Enterprise connectivity linking remote offices or campuses
- Industrial applications connecting warehouses, manufacturing sites
- Surveillance systems transmitting high-bandwidth video feeds
- Rural internet providing connectivity where fiber isn’t available
Installation Considerations
The narrow beam width requires precise alignment between stations. The integrated mounting bracket allows for fine-tuning during setup. Line of sight (or near line of sight with minimal Fresnel zone obstruction) is essential for optimal performance.
