Ubiquiti U5G-Max UniFi 5G Max 3.4 Gbps 5G Modem with Dual SIM
Overview
The Ubiquiti U5G-Max is the UniFi 5G Max, a 5G cellular modem designed to provide high-speed cellular connectivity for UniFi deployments. Ubiquiti specifies peak 5G NSA downlink speeds of up to 3.4 Gbps and positions the device for primary internet connectivity or fast failover. The unit connects to a UniFi deployment through its 2.5 GbE RJ45 interface and is powered through PoE.
5G and Cellular Connectivity
The U5G-Max supports 5G NR, 4G LTE, and 3G UMTS cellular networks. Its 5G NR coverage includes bands n1, n2, n3, n5, n7, n8, n12, n13, n14, n18, n20, n25, n26, n28, n29, n30, n38, n40, n41, n48, n66, n71, n75, n76, n77, n78, and n79. Ubiquiti specifies peak data rates of 3.4 Gbps downlink and 560 Mbps uplink for 5G NSA, and 1.8 Gbps downlink and 650 Mbps uplink for 5G SA.
SIM and Ethernet Interface
The device supports dual SIM operation with two Nano-SIM slots, while Ubiquiti also specifies Nano-SIM or eSIM support. The networking interface is a 2.5 GbE RJ45 port that carries the 5G NR and LTE connection to the UniFi network. Ubiquiti identifies dual SIM/eSIM and seamless failover as part of the product's deployment capabilities.
Power and Deployment
The U5G-Max uses PoE for power and supports an input voltage range of 44–57V DC. Maximum power consumption is 14.5W. The device can be deployed using the included desktop stand, wall mount, or window mount. The enclosure uses polycarbonate and aluminum alloy, with IK04 impact resistance.
Management and Display
Management is provided through Ethernet, and the U5G-Max includes a 1.3-inch touchscreen for device information and interaction. Ubiquiti specifies UniFi Network version 10.0.162 or later as the application requirement. A factory-reset button is also provided.
Key Features
- 5G NR modem with peak 3.4 Gbps NSA downlink
- Dual SIM with Nano-SIM and eSIM support
- 2.5 GbE RJ45 networking interface
- PoE power with 44–57V DC supported input range
- 1.3-inch touchscreen and UniFi Network management
Applications
The U5G-Max can provide cellular internet access to UniFi deployments as a primary WAN connection or as a fast failover path. Its 2.5 GbE interface and PoE power method allow it to integrate directly with compatible UniFi network infrastructure without requiring a separate local DC power connection.
DC Supplies Product Note
The U5G-Max requires a PoE power source within its specified 44–57V DC input range. For deployment planning, verify that the selected UniFi PoE port or PoE source can provide the required power budget before installation, particularly when the device is being added to an existing network infrastructure.
