BBU3900 in a Standard 19-Inch Cabinet Application scenario 1

Launch 3G services on the basis of a 2G site

2G BTS RF Cable

Benefit of this Application Scenario: Can reside in any standard 19-inch-wide and 2-U-high cabinet Can be installed on the metal pole and close to the antenna The BBU3900 and RRU can share the power supply and antenna systems of the 2G network Enables operators to launch 3G services on the existent 2G network at a very low costHUAWEI TECHNOLOGIES CO., LTD.

DBS3900 Capacity and CharacteristicsSpecification of the DBS3900 High capacity;

BBU3900 supports 24 cells, with 1,536 UL CEs and 1,536 DL CEs. One RRU3804 supports the 4-carrier configuration. When the NodeB expands from 1x1 to 1x4 or from 3x1 to 3x4, no extra RRU is required.

Characteristics of the DBS3900 Supports RRU cascading

When using the 1.25 G optical module, cascading levels 4 When using the 2.5 G optical module, cascading levels 8
