RRU3268 is newly designed to support the 2T2R mode, improving output power and carrier
capacity.
The RRU3268 is configured with the bias tee (BT). The internal BT couples RF signals and
OOK signals and transmits them through the TX/RX port A. The internal BT also supplies
power to the tower mounted amplifier (TMA).
The software of the RRU3268 is backward compatible with the eNodeB and OSS of the N-1
and N-2 versions, where N indicates the current version number, for example,
SRAN10.0/eRAN8.0 in this document. In addition, the software package of the three versions
includes the RRU3268 software components. Therefore, the RRU3268 of SRAN8.0/eRAN6.0
can be used for SRAN6.0/eRAN2.1, SRAN7.0/eRAN3.0, SRAN8.0/eRAN6.0, and
SRAN9.0/eRAN7.0, without affecting KPIs.
