MikroTik R11e-5HnD – Professional Wireless Network Card miniPCIe for SMB and Industrial Infrastructure

The MikroTik R11e-5HnD is a high-power 5 GHz miniPCI-e wireless card built for outdoor installations where signal strength, range, and precise antenna alignment are critical. Designed primarily for the RB912 series and RB800 platform, the card covers the 4920-5920 MHz spectrum with 802.11a/n dual-chain support and dual MMCX connectors for external antenna attachment.

The card features built-in LED indicators directly on the board — displaying wireless mode, connection status, TX/RX activity, and signal strength — significantly simplifying on-site installation and antenna alignment without requiring a laptop or additional diagnostic tools in the field. The dual-chain 802.11n chipset delivers up to 300 Mbps and provides stable performance for outdoor point-to-point and point-to-multipoint links.

It installs into the miniPCI-e slot of compatible devices — RB912, RB800, or via the RB14e adapter card — turning a RouterBOARD into a high-power outdoor wireless platform. The tested operating temperature range of -40°C to +65°C confirms reliable performance in harsh climatic conditions without RF characteristic degradation.

It is the right choice for outdoor 5 GHz wireless deployments where transmission power is a critical factor, for upgrading RB912 or RB800 hardware to dual-chain Wireless N, for backhaul and distribution links in outdoor networks, and for installers who need direct visual feedback on the device during antenna alignment without additional equipment.
