Ubiquiti SuperLink Gateway HA — Professional IoT Gateway with LTE Backup for Security Infrastructure

The USL-G2-Gateway-HA is a high-availability wireless gateway for enterprise IoT networks, video surveillance systems, and distributed infrastructures where operational continuity is critical. It is deployed in commercial buildings, campuses, and industrial facilities requiring uninterrupted sensor and peripheral connectivity — with SuperLink coverage up to 2 km, supporting 96 SuperLink clients and 128 Thread clients simultaneously.

Compared to the standard USL-Gateway, the HA variant adds Thread (IEEE 802.15.4) support for sensor mesh networking, an internal battery providing 2.2 hours of backup operation during power loss, and a 1.14" status display for local monitoring. SuperLink TX power reaches 27 dBm, and a 10/100 MbE RJ45 port handles LAN integration. Power input options include PoE, USB-C (5V/1A), or external DC (12V/1A), with a maximum draw of 6.5W. The polycarbonate and aluminum alloy enclosure is rated for 0–40°C operation.

USL-G2-Gateway-HA integrates natively with UniFi Protect, managed centrally via web application or mobile app on iOS and Android. Wall and DIN rail mounting options support both rack-based and field deployments. CE, FCC, and IC certifications alongside NDAA compliance qualify it for government and regulated-sector procurement.

Recommended for system integrators and enterprise IT teams managing large-scale UniFi Protect deployments where downtime is not acceptable. The ideal choice for extending wireless coverage into uncabled areas with power redundancy requirements and native sensor mesh support.
