Typical Configurations; Overview - Huawei Airbridge BTS3612A-1900 Technical Manual

Technical Manual
Airbridge BTS3612A CDMA Base Station
II. Advantage
The satellite synchronization antenna & feeder is not required, which saves the
investment. This networking mode is suitable in the areas like the metro where the
satellite synchronization antenna & feeder cannot be easily installed.
Compared with repeater, ODU3601C supports the centralized management of the
upper-level BTS, which facilitates the network planning.
III. Disavantage
The failure of upper-level BTS may affect the normal operation of lower-level BTS.
IV. Implementation
The single-mode BRDM can be used for the cascading of ODU3601C. ODU3601C
can be configured as either in a certain sector of the master BTS, or as an
independent cell.

8.6 Typical Configurations

8.6.1 Overview

The BTS3612A support 450MHz band, 800MHz band and 1900MHz band, the typical
configurations for 450MHz band are listed as below (Without diversity transmission),
and the configurations for 800MHz band and 1900MHz band is similar to the
configurations for 450MHz band.
I. Single cabinet configuration
Omni cell, 1~2 carriers (DFU or DDU adopted).
3 sectors, 1 carrier per sector (DFU adopted).
3 sectors, 1~2 carriers per sector (DDU adopted).
II. Combined configuration (with two cabinets)
3 sectors, 3~4 carriers per sector (CDU adopted).
6 sectors, 1~2 carriers per sector (DDU adopted).
Omni configuration is generally represented by O(X), where X indicates the number
of carriers. For example, O(2) represents the omni configuration with two carriers.
The three-sector directional configuration is represented by S(X/X/X), and the
six-sector one is represented by S(X/X/X/X/X/X).
The following will detail the typical configurations including O(2), S(2/2/2), and
S(4/4/4).
