Ubiquiti UniFi 5G Cellular Modem Max (U5G-Max)
Ubiquiti UniFi 5G Max (U5G-Max) Enterprise 5G Cellular Modem
Overview: The UniFi 5G Max (U5G-Max) is an enterprise-grade cellular modem that adds 5G NR and LTE WAN connectivity to the UniFi ecosystem. It features a 2.5 GbE RJ45 port, PoE input, Nano SIM/eSIM support, and centralized management through UniFi Network 10.0.162 and later.
Description: The U5G-Max is designed for branch offices, retail sites, campuses, hotels, factory field offices, and temporary project locations that require fiber or xDSL backup, or a primary cellular WAN connection. With 5G NR and LTE radio support, it delivers high-bandwidth, low-latency connectivity over operator networks. Four embedded cellular antennas support stable signal reception and efficient coverage acquisition in field deployments, making it suitable for POS, IoT, IP cameras, VoIP, and cloud applications that require continuous WAN availability.
The hardware architecture is built for enterprise field conditions with a polycarbonate and aluminum alloy enclosure, IK04 tamper resistance, and a 1.3-inch touchscreen. The 2.5 GbE RJ45 port carries cellular connectivity into UniFi gateways and switching infrastructure at high speed, while the PoE input allows single-cable power delivery with a maximum power consumption of 14.5W. Nano SIM and eSIM options provide deployment flexibility for carrier onboarding and redundancy scenarios. A desktop stand, wall mount, and window mount are included in the box.
UniFi Network 10.0.162 and later provides centralized management and integrates cellular WAN connectivity with enterprise network policies. Routing, VLAN segmentation, and roaming decisions are defined at the UniFi gateway and controller layer, while the U5G-Max carries cellular access into that architecture over 2.5 GbE. NDAA compliance supports regulated deployments, and FCC, IC, CE, PTCRB, GCF, AT&T, and T-Mobile certifications address regional and carrier compliance requirements. In office, campus, hotel, factory, and field environments with dense client populations, it provides cellular WAN capacity and business continuity as a reliable infrastructure component.
