Ubiquiti UniFi 5G Max Outdoor (U5G-Max-Outdoor) — Outdoor 5G/LTE Cellular Modem

Overview: The UniFi 5G Max Outdoor (U5G-Max-Outdoor) is a weather-hardened 5G NR / LTE cellular modem that integrates directly into the UniFi ecosystem. It runs on a single 2.5 GbE RJ45 link with PoE power and provides UniFi gateways with either a primary WAN or an automatically engaged backup WAN path wherever fiber or xDSL infrastructure is unavailable. Its enclosure is rated IPX6 — and IP67 once the cable-gland door kit is fitted — with an operating range of -40 to 65 °C, and the included pole/wall mount carries 91 N at 200 km/h wind loading, making it suitable for enterprise field deployments.

Description: Within an enterprise network architecture, the UniFi 5G Max Outdoor acts as the cellular WAN source. The device connects to a UniFi gateway over its 2.5 GbE RJ45 port and lifts the cellular link into the WAN layer, so redundancy policies configured in the UniFi Network console keep traffic flowing over 5G/LTE whenever the primary fiber circuit drops. PoE powering reduces field cabling to a single Cat6 run: the same cable carries both data and power, eliminating separate power drops, outdoor sockets and auxiliary UPS enclosures at exterior installation points. A maximum power draw of 14.5 W keeps the unit compatible with UniFi switches that carry a standard PoE budget while producing a low thermal footprint in sealed outdoor enclosures.

On the radio side, the unit ships with six embedded cellular antennas, two of which are high-gain elements for the downlink with 9 dBi peak gain and 85° x 85° beamwidth. This antenna architecture preserves a stable link margin even at cell edge. Throughput scales with the deployed mode: 3.4 Gbps downlink / 560 Mbps uplink on 5G NSA, 1.8 Gbps downlink / 650 Mbps uplink on 5G SA, and 1.6 Gbps downlink / 210 Mbps uplink on 4G LTE. Support for both nano SIM and eSIM allows remote provisioning and carrier switching in multi-operator field strategies without dispatching a technician to swap a physical card — a direct reduction in truck-roll cost for WISPs and multi-site organizations.

Management lives entirely in UniFi OS. The device appears in the UniFi Network application as a managed inventory element with its Ethernet and 5G NR link status, so cellular connection state and signal metrics are monitored from the central console. IT teams running dozens of sites — retail branches, factories, hotels, campuses, temporary construction sites — therefore treat cellular WAN links under the same policy set as wired WANs: VLAN segmentation, traffic prioritization, WAN load balancing and failover rules are applied from one control plane. Typical deployments include production-line telemetry on factory floors, guest-network redundancy in hospitality, temporary event coverage on campuses, and NDAA-compliant procurement for municipal and public-sector projects.

Physical resilience is where the platform differentiates itself. The aluminum-alloy and UV-stabilized polycarbonate enclosure serves years of direct sun exposure without yellowing or embrittlement, and the mount hardware is UV-stabilized polycarbonate as well. IPX6 protection rises to IP67 with the cable-gland door kit installed, delivering full sealing against heavy rain, dust and standing water. The included kit supports pole mounting on 1–2.5 in (25–63.5 mm) outer-diameter pipe and wall mounting, while the 91 N load rating at 200 km/h wind speed provides structural safety on rooftops and open terrain. The device weighs 1.2 kg with 130 g of mount hardware and measures 220 x 165 x 66.9 mm (122 mm deep with mount), fitting tight field profiles. NDAA compliance clears supply-chain approval for public tenders and critical infrastructure programs.
