Radio configuration – 4T4R, 4 × 40 W (160 W total output).
Frequency range (Band 3) – TX 1805–1880 MHz / RX 1710–1785 MHz.
Instantaneous bandwidth – 75 MHz (DL/UL).
Supported technologies – LTE FDD (AirScale SRAN LTE 18 SP and later).
MIMO capability – 2×2 MIMO per sector.
Ingress protection – IP65 (fully outdoor rated).
Cooling – Natural convection / fan-less.
Compliance – 3GPP Band 3, RoHS & REACH conformant.
