RRU3971 for Multi-mode 1800MHz (4*40W)

Overview

The RRU3971 is an outdoor remote radio unit. It is the radio frequency (RF) part of adistributed base station and can be located near antennas. The RRU397l can modulate.demodulate, combine, and divide baseband and RF signals. It also processes baseband and RFsignal data. With the software-defined radio (SDR) technology, the RRU3971 supports thetriple-mode or dual-mode operation of any two modes of GSM, UMTS, and LTE throughsoftware configuration modification. Also, RRU397l supports LN, or GLN mode.Adopting an innovative design, RRU397l is able to work in 4 TX and 4 RX mode andtherefore supports higher output power and larger carrier capacity.
The software version ofthe RRU3971 (1800 MHz/1900 MHz/AWS) is SRAN11.1, which iscompatible with the N-1 and N-2 versions of MBTS, MBSC, and OSS NEs. Therefore, theRRU3971 can be used with products ofSRAN9.0, SRAN10.1 and SRAN11.1 versions. Althese three versions include the RRU397l software components. The RRU3971 used inSRAN9.0, SRAN10.1 and SRAN11.1 has no impact on the KPl of products.
The software version ofthe RRU3971 (2100 MHz) is SRAN12.0, which is compatible withthe N-1 and N-2 versions of MBTS, MBSC, and OSS NEs. Therefore, the RRU3971 can beused with products ofSRAN10.1, SRAN11.1 and SRAN12.0 versions. All these threeversions include the RRU3971 software components. The RRU3971 used in SRAN10.1,SRAN11.1, and SRAN12.0 has no impact on the KPl of products.
