Designed for high-speed mobile connectivity, MikroTik’s RB-ATL18 features an integrated Category 18 LTE modem, a Micro SIM slot, and a Gigabit Ethernet port with PoE-in functionality. The unit leverages 4x4 MIMO technology and supports a broad frequency spectrum through a specialized internal array: four high-gain antennas handle the 1.7–2.7 GHz range, while two low-band antennas support 700 MHz–1 GHz frequencies, including LTE Band 28.
