ZBT Z8119AX-M2-T: Dual-Module 5G/4G Router with Two M.2 Slots, Two SIM + Two eSIM, USB 3.0 and Wi-Fi 6

Delivering the proven performance of the MT7981B ARM Cortex-A53 dual-core platform in a dual-module configuration, the ZBT Z8119AX-M2-T offers enterprise-grade dual-WAN 5G/4G cellular redundancy with a more accessible form factor and infrastructure footprint. With two M.2 module slots (USB 3.0 BUS), two NANO SIM + two eSIM (6×8mm) slots, a dedicated USB 3.0 data port, 12 detachable high-gain SMA antennas, and Wi-Fi 6 dual-band delivering up to 2975Mbps total wireless throughput — the Z8119AX-M2-T is the right platform for enterprise branch offices, managed service deployments, and ODM/OEM builds that require dual-carrier WAN redundancy without the full four-module footprint of the Z8109AX-M2-T-PSE.

Two M.2 Modules, Two SIM + Two eSIM: Dual-WAN Carrier Redundancy

The Z8119AX-M2-T is built around a two-module, two-SIM architecture that enables simultaneous dual-WAN cellular operation across two independent 5G or 4G LTE modem modules. Each M.2 slot (USB 3.0 BUS) accommodates a dedicated modem module, and each is paired with its own NANO SIM slot plus an eSIM (6×8mm) slot — providing both physical SIM carrier flexibility and remote eSIM provisioning on each WAN path independently.

This dual-path design enables active-active load balancing and automatic failover between two carriers — ensuring continuous WAN connectivity for enterprise branch offices, retail locations, and managed service installations where single-carrier downtime is unacceptable but a full four-module platform is not required. The USB 3.0 port adds a dedicated data expansion interface for storage or peripheral connectivity alongside the cellular and Ethernet interfaces.

Hardware Architecture: MT7981B ARM Cortex-A53 + MT7976CN Wi-Fi 6

The Z8119AX-M2-T is powered by the MT7981B ARM Cortex-A53 dual-core CPU at 1.3GHz — the same proven enterprise platform as the Z8109AX-M2-T-PSE — with the MT7976CN Wi-Fi 6 chipset delivering dual-band IEEE 802.11n/g/b/a/ac/ax operation: 573Mbps on 2.4GHz and 2402Mbps on 5.8GHz for a total of 2975Mbps wireless throughput.

Memory configuration matches the enterprise platform: DDR4 512MB (configurable 256MB or 1GB), optional eMMC storage up to 256GB, 16MB Nor Flash, and 128MB SPI NAND Flash (optional 256MB). The Gigabit interface delivers 1× WAN and 3× LAN ports at 1000Mbps for wired downstream device connectivity. Twelve detachable high-gain SMA antennas cover both M.2 modem modules and the dual-band Wi-Fi 6 radios for comprehensive RF performance across all active interfaces.
