MikroTik R11eL-FG621-EA Network Card – Reliable LTE Connectivity for Professional Networks

The MikroTik R11eL-FG621-EA is a miniPCIe LTE Cat6 modem designed to upgrade MikroTik devices with high-speed mobile connectivity across the EMEA, APAC, and Australian regions. It is widely used in MikroTik routers and gateways as a primary LTE connection or internet failover in infrastructures where continuous connectivity is critical. Support for the B28 band (700 MHz) and carrier aggregation makes it effective in both congested urban networks and rural areas with weaker signal conditions.

The modem operates at LTE Cat6 speeds of up to 300 Mbps downlink and 50 Mbps uplink, with 3G Category 8 support reaching up to 42.2 Mbps. Carrier aggregation enables simultaneous use of multiple LTE bands — a significant advantage in high-density environments, where real-world deployments have shown internet speeds doubling compared to connections without aggregation. Supported FDD bands include B1, B3, B5, B7, B8, B20, and B28, with TDD bands B38, B40, and B41 — comprehensive coverage for operators across Europe, the Middle East, Africa, Asia-Pacific, and Australia.

The R11eL-FG621-EA is natively compatible in full-size form factor with the LtAP, and functions in any RouterOS product with a PCIe slot or via USB adapter. It integrates into existing MikroTik infrastructure without complex additional configuration, with LTE connectivity managed directly from RouterOS through the standard administration interface.

It is recommended for upgrading LtAP routers in mobile and outdoor deployments, adding LTE Cat6 connectivity to fixed gateways as a primary link or failover, improving coverage in rural areas where band aggregation delivers meaningful speed gains, and for ISP and industrial deployments across EMEA and APAC regions requiring B28 band support. An operating temperature range of -40°C to +70°C confirms suitability for demanding outdoor environments.
