2.3 RHUB3908 Equipment
The RHUB3908 converges the common public radio interface (CPRI) data from the RF
remote device. The main functions of the RHUB3908 are as follows:
The RHUB3908 works with the BBU and pRRU to provide indoor coverage.
In the downlink, the RHUB3908 receives the baseband data from the BBU, splits the
data into different routes, and sends it to pRRUs. In the uplink, the RHUB3908
converges the data from pRRUs and sends the data to the BBU.
The internal PoE module in the RHUB3908 provides power to the pRRU.
