Networking Modes; Regular Installation Scenario - Huawei AISU User Manual

AISU
User Manual
The AISU is a remote antenna extension (RAE) device which can be installed in two
scenarios. Based on the number of RAE devices connected to the control link, the AISU can
be installed in regular mode or daisy-chain mode.

4.1 Regular Installation Scenario

In regular installation mode, only one AISU is installed in a sector, or other antenna line
devices (ALDs) in the link between the RRU and AISU do not have any RAE devices. The
following figures show the AISU installed in regular mode.

NOTE

An RRU can control only one AISU, and the AISU must be installed on the antenna connected to the
RRU.

The following figures show typical AISU application scenarios. For complex scenarios, contact
Huawei engineers before using the AISU.
 When an antenna shared by different operators is equipped with an AISU, engineering parameters
can be obtained only on eNodeBs in the AISU link. Operators cannot share the AISU automatically
to obtain engineering parameters. (This function may be supported in later versions.)
