NOTE
The hardware shown in Figure 2-1 can be applied in all modes, which is a reference only. The BBU can
be configured with baseband boards at different modes to meet requirements of different scenarios, and
the pRRU can be configured with different RF daughter boards at different modes to support multimode
applications. The connection principles for the LampSite solution are as follows:
The distance between the BBU and the lowest level RHUB cannot be greater than 10
km.
A maximum of four levels of RHUBs can be cascaded. However, pRRUs cannot be
cascaded.
One RHUB provides eight CPRI_E ports (CPRI_E0 to CPRI_E7), with each port
connected to one pRRU. An RHUB can be connected to a maximum of eight pRRUs.
The pRRU and RHUB are connected by CAT5e cables. With the internal PoE module
providing power, the distance of the two devices can be extended by the Extender up to a
total distance of 200 m.
