Ubiquiti PS-5AC 5 GHz Wireless Base Station
Overview
The Ubiquiti PS-5AC is a compact 5 GHz base station designed for point-to-point and point-to-multipoint wireless bridging in enterprise and carrier deployments. Operating on the 802.11ac standard, the PS-5AC (model number found on all packaging) delivers reliable backhaul and access point functionality with minimal power consumption and straightforward deployment characteristics suitable for infrastructure applications requiring lightweight, weatherproof equipment.
Key Features
The PS-5AC operates at 1 Gbps throughput over a single Ethernet port and draws a maximum of 10W, powered exclusively through 24V passive PoE using a 2-pair connection. The base station form factor includes a dedicated 2.4 GHz management radio for out-of-band device administration and an LED status indicator for quick operational diagnostics. This architecture minimizes installation complexity while maintaining essential visibility into device state and connectivity.
Deployment Scenarios
The PS-5AC suits wireless bridge installations connecting distant buildings, campus networks, or remote sites where fiber deployment is impractical. The 5 GHz band provides interference mitigation in dense RF environments. Single-port design constrains use cases to dedicated backhaul or access roles rather than integrated switching applications. Typical installations include carrier point-to-point links, outdoor mesh networks, and secondary connectivity paths requiring low-power operation.
Network Integration
Integration into existing infrastructure requires standard PoE power delivery and Layer 2 or Layer 3 routing configuration via the 2.4 GHz management interface. The PS-5AC belongs to Ubiquiti's Access Points product family, enabling management through standard UniFi controller deployments if controller integration is desired. Single Ethernet port architecture simplifies cabling but requires separate switching or routing infrastructure upstream.
Installation Notes
Weighing 5.35 pounds, the PS-5AC permits mounting on standard poles or wall brackets. The device is manufactured in China and ships ready for deployment. The Ubiquiti PS-5AC requires line-of-sight positioning for optimal 5 GHz propagation and should be installed with consideration for fresnel zone clearance in point-to-point configurations.
Marty Allison, Infrastructure Architect
"The PS-5AC remains a solid choice for carriers and integrators needing straightforward 5 GHz backhaul. The passive PoE design eliminates injector logistics, and the 2.4 GHz management band ensures you can troubleshoot without disrupting the primary link. Just remember: single Ethernet port means this is a purpose-built backhaul tool, not a general-purpose access point. Plan your network topology accordingly, and the PS-5AC will deliver years of stable operation. The Ubiquiti PS-5AC pricing reflects its positioning as infrastructure-grade equipment, not consumer Wi-Fi."
