MikroTik R11e-2HnD 2.4GHz 802.11n Dual-Chain miniPCI-e Wireless Card

The MikroTik R11e-2HnD is a dual-chain 2.4 GHz miniPCI-Express wireless card built on the AR9582 chipset and supporting 802.11b/g/n (Wi-Fi 4) standards. Its low-profile, compact design—complete with a miniaturized heat sink and dual u.FL antenna connectors—makes it well suited for space-constrained embedded and router deployments. With a frequency range of 2312–2732 MHz, a maximum output power of 800 mW (up to 29 dBm depending on data rate), and a maximum power consumption of just 4.6 W, the card delivers high-power wireless performance while remaining efficient. Built-in ESD protection and an operating temperature range of -40 °C to +65 °C contribute to reliable operation in demanding environments. Onboard LED indicators provide real-time visibility into wireless mode, connection status, TX/RX activity, and signal strength, simplifying installation and antenna alignment.

Key features & benefits

• High-Power Dual-Chain 2.4 GHz Radio — Dual-chain 802.11b/g/n architecture on the AR9582 chipset delivers up to 29 dBm transmit power and receive sensitivity as low as -100 dBm at 1 Mbps, supporting robust links even in challenging RF environments.
• Wide Frequency Coverage — The card operates across a 2312–2732 MHz frequency range, providing flexibility for regulatory domains and specialized frequency planning beyond the standard 2.4 GHz ISM band.
• Onboard LED Indicators — Integrated LEDs report wireless mode, connection status, TX and RX activity, and signal strength directly on the card, eliminating the need for external diagnostic tools during installation and alignment.
• Built-In ESD Protection — Electrostatic discharge protection is integrated into the card's design, guarding sensitive RF and digital circuitry against damage during handling and extending long-term reliability.
• Compact Low-Profile Form Factor — At 51 × 30 × 6 mm with a low-profile heat sink, the R11e-2HnD fits in space-constrained enclosures and router boards without compromising thermal management.
• Dual u.FL Antenna Connectors — Two u.FL connectors allow independent connection of two antenna chains, enabling full spatial diversity and MIMO operation for improved throughput and link stability.
• Wide Operating Temperature Range — Rated from -40 °C to +65 °C, the card is suitable for outdoor enclosures, industrial equipment, and other deployments exposed to temperature extremes.
• Low Power Consumption — A maximum power draw of 4.6 W keeps thermal load and power-budget requirements minimal, making the card practical for fanless and battery-adjacent designs.
