MikroTik R11e-LR2 Gateway Concentrator – Industrial Connectivity Solution

The MikroTik R11e-LR2 is a LoRa® concentrator gateway card operating at 2.4 GHz in miniPCIe form factor, designed to add IoT sensor network capabilities to any compatible MikroTik device without replacing the host hardware. It is commonly used as a 2.4 GHz LoRa® expansion module for MikroTik routers and access points, a miniPCIe IoT gateway card for industrial sensor deployments, and a high-density LoRa® concentrator for facilities where the 868/915 MHz spectrum is congested. The 2.4 GHz band delivers higher bandwidth, faster data rates, and reduced air time compared to traditional sub-GHz LoRa® implementations.

The card supports 4 simultaneous RX channels and 1 TX channel, enabling parallel reception from multiple sensors without packet collisions — a critical capability in high-density IoT installations. Chirp Spread Spectrum modulation ensures the LoRa® signal does not interfere with the host device's existing 2.4 GHz Wi-Fi radio, allowing both to operate concurrently without performance degradation. With a maximum draw of 2W and a tested operating range of -40°C to +70°C, the R11e-LR2 is suited for permanent industrial and outdoor installations.

Installation requires any MikroTik miniPCIe slot with active USB lines — compatible platforms include LtAP, LtAP LR8, and other devices in the MikroTik lineup that meet this requirement. This allows an existing router or access point to function as a fully capable 2.4 GHz LoRa® gateway without dedicated standalone hardware. Native integration with RouterOS and support for The Things Network infrastructure simplifies deployment and reduces time-to-operation for new IoT projects.

The R11e-LR2 is the right choice for industrial facilities with hundreds of simultaneously transmitting sensors where sub-GHz LoRa® capacity is insufficient, for agricultural IoT networks monitoring soil, temperature, and irrigation across large areas, for warehouse and logistics environments requiring indoor sensor coverage, for smart building deployments with dense environmental monitoring, and for any IoT project where channel throughput and concurrent device capacity take priority over maximum transmission range.
