MikroTik R52H miniPCI Wireless Network Card for ISP & Business Deployments

R52H is a dual-band miniPCI wireless card for high-speed applications in professional networks, supporting both 2.4GHz and 5GHz frequency bands. It is commonly deployed in outdoor wireless infrastructures for long-range point-to-point links and distributed networks where performance and coverage range are critical.

The card supports 802.11a/b/g standards and Turbo mode for faster data transfers, providing flexibility in frequency band selection based on deployment conditions. Two U.fl connectors allow the use of external antennas for precise directional coverage and signal optimization. Reliable operation between -40°C and +70°C makes it suitable for permanent outdoor installations in harsh climatic conditions, backed by an MTBF of 100,000 hours.

R52H is optimized for MikroTik's proprietary Nstreme protocol, which overcomes the speed and distance limitations of the IEEE 802.11 standard in point-to-point and point-to-multipoint connections. The Nstreme-dual protocol enables true full-duplex wireless communication using a pair of cards — one for transmitting and one for receiving — significantly boosting long-range wireless link performance. Native integration with MikroTik RouterOS enables advanced configuration and centralized management.

Recommended for ISPs and integrators building long-range wireless links, for distributed networks in areas without cabled infrastructure, and for deployments where the Nstreme protocol provides a competitive advantage over standard 802.11 solutions. Also suitable for dual-band gateways in mixed 2.4/5GHz infrastructures. This product is discontinued.
