MikroTik RB911-5HnD-US 5GHz 300Mbps WiFi 4 RouterBoard PoE

The MikroTik RB911-5HnD-US is a compact RouterBOARD platform engineered for cost-effective Customer Premises Equipment (CPE) deployments in the 5 GHz band. Built around an AR9344 MIPSBE processor running at 600 MHz with 64 MB of RAM, the board delivers capable routing and wireless performance in a 105×105 mm form factor. The US version is factory-locked to the 5170–5250 MHz and 5725–5835 MHz frequency ranges in compliance with FCC regulations, a restriction that cannot be modified. Powered by passive PoE across a wide 6–30 V input range and drawing no more than 7 W, the RB911-5HnD-US is well suited for point-to-point links, wireless ISP last-mile connections, and any application where a low-profile, low-power 5 GHz CPE node is required. RouterOS License Level 3 provides the routing, firewall, and wireless management capabilities expected of MikroTik infrastructure.

Key features & benefits

• Dual-Chain 5 GHz 802.11a/n Radio — The onboard AR9344-based wireless card operates across two spatial streams, delivering up to 300 Mbit/s maximum data rate on the 5 GHz band under 802.11a/n (Wi-Fi 4), enabling robust throughput for CPE and backhaul roles.
• US-Compliant Factory Frequency Lock — The radio is permanently restricted to 5170–5250 MHz and 5725–5835 MHz, ensuring out-of-the-box FCC compliance for US deployments without any additional configuration steps.
• 600 MHz AR9344 CPU with 64 MB RAM — The single-core MIPSBE processor and 64 MB of RAM provide the processing headroom needed for routing, NAT, and wireless management tasks typical of CPE and small access-point applications.
• Wide-Range Passive PoE Input — A single passive PoE input accepting 6–30 V DC allows flexible powering from a wide variety of injectors and power supplies, simplifying outdoor or remote installations where a single cable is preferred.
• Passive Cooling and Wide Operating Temperature — With no moving parts and a tested ambient operating range of -40 °C to +70 °C, the board is designed for continuous unattended deployment in challenging outdoor or industrial thermal environments.
• RouterOS Level 3 License — Ships with RouterOS License Level 3, providing access to MikroTik's full suite of routing protocols, firewall rules, bandwidth management, and wireless configuration tools via Winbox, WebFig, or CLI.
• 16 MB FLASH Storage — Onboard 16 MB FLASH storage retains the operating system and configuration through power cycles, supporting reliable, maintenance-free field operation.
• Multi-Certification Compliance — Carries CE, FCC, IC, EAC, and RoHS certifications, facilitating deployment across multiple regulatory jurisdictions and meeting environmental material restrictions.
