Wireless kit MikroTik KNOT LR9G RB924iR-2nD-BT5 with BG770A and R11e-LR9 902–928 MHz

The MikroTik KNOT LR9G wireless kit combines an RB924iR-2nD-BT5 access device, a BG770A cellular module and an R11e-LR9 extension to operate in the 902–928 MHz band. This kit is designed for low‑frequency wireless links and long‑range connectivity where sub‑GHz frequencies offer improved penetration through obstacles and increased link distance. It supports deployment in point‑to‑point and point‑to‑multipoint topologies and is suitable for outdoor installations and IoT or backhaul use cases requiring reliable, long‑range radio performance.

Advantages

The integrated RB924iR-2nD-BT5 provides a compact outdoor access node with integrated radio and multiple connectivity options while the BG770A module adds cellular connectivity flexibility. The R11e-LR9 extension enables operation in the 902–928 MHz range, which improves coverage and wall penetration compared with higher frequencies. The kit is built for extended range, low power consumption profiles typical of sub‑GHz links, and flexible deployment scenarios including fixed wireless and sensor networks.

Suitable for

• Long‑range point‑to‑point wireless links in rural or suburban areas
• Point‑to‑multipoint networks for IoT sensors and remote telemetry
• Outdoor installations requiring improved penetration through vegetation or structures
• Backhaul or last‑mile connectivity where sub‑GHz propagation is advantageous

How to use

Mount the RB924iR‑2nD‑BT5 outdoors according to local regulations, connect the R11e‑LR9 extension into the compatible slot and install the BG770A module if cellular connectivity is required. Configure radio settings to operate in the 902–928 MHz band and set link parameters such as channel width, power level and antenna alignment for optimal performance. Use RouterOS or the device web interface to define network modes, security settings and routing or bridge functions. Perform a site survey and adjust antenna orientation to achieve the desired link quality and throughput.

Usage recommendations

For reliable long‑range performance, select appropriate antennas and ensure clear line of sight where possible; limit transmit power to meet regional regulations for the 902–928 MHz band. Regularly update device firmware and monitor link statistics to maintain stable operation for IoT and backhaul deployments.
