Sieťová karta MikroTik R11E-LR2 interná

The MikroTik R11E-LR2 is an internal network card that adds 2.4 GHz LoRa® connectivity to MikroTik devices with a mini PCIe slot and connected USB lines. It supports four receive channels and one transmit channel, offering higher bandwidth and data rates compared with sub‑gigahertz LoRa® while maintaining low air time. Using Chirp modulation, the module coexists with 2.4 GHz WLAN without causing interference, making it suitable for dense industrial sensor deployments.

Advantages

The R11E-LR2 provides 2.4 GHz LoRa® communication through a Mini PCI Express interface, enabling higher throughput and shorter transmission times than traditional LoRa® bands. Its support for multiple RX channels and a single TX channel allows simultaneous reception on several channels. The device requires a mini PCIe slot with USB lines and comes in a compact, green form factor compatible with MikroTik hardware.

Suitable for

• Industrial sensor networks with high device density
• MikroTik routers or gateways that have mini PCIe slots with USB lines
• Applications requiring higher data rates and reduced air time

Key specifications

• Connection type: Mini PCI Express (requires USB lines)
• Frequency band: 2.4 GHz LoRa®
• RX/TX channels: 4 RX, 1 TX
• Product colour: Green
• Brand/Model: MikroTik R11e-LR2

How to use

Insert the R11E-LR2 into a compatible mini PCIe slot on a MikroTik device that provides USB lines. Configure LoRa® parameters and channel settings in the device management interface according to your network plan. Ensure antenna connection and proper grounding before powering the device. Monitor channel usage and device logs to verify operation.

Recommendations

Install the card in a device certified for your region, use appropriate antennas for 2.4 GHz LoRa®, and place the host device to minimize RF obstruction. Verify mini PCIe USB connectivity and update MikroTik firmware/drivers for best compatibility.
