small dimensioning design
RRU can be installed near antenna
The numbers of BBU and RRU can be configured according to different requirements
Traditional outdoor macro NodeB
Difficult to transport and move
Need large space to locate
Require long feeder

DBS3800 Deployment
Application scenario 1 : Launch 3G services on the basis of a 2G site

DBS3800 Deployment
Application scenario 2 : Launch a new 3G outdoor site without an equip
ment room
HUAWEI TECHNOLOGIES CO., LTD. Page 11All rights reserved
DBS3800 Deployment
Application scenario 3:
Launch a new 3G indoor site, there is an equipment room but the space is limited and load-bearing capacity is week
HUAWEI TECHNOLOGIES CO., LTD. Page 12All rights reserved
DBS3800 Deployment
Application scenario 4 : Launching a new 3G outdoor site, the operator has no equipment roo
m or fiber resources, or it is very hard to route optical fibers

DBS3800 Characteristics supports circuit domain (CS) and packet (PS) domain services
supports positioning services
supports softer handover, soft handover and hard handover
Supports transmit diversity mode and receive diversity mode
Supports high-speed downlink packet access (HSDPA) technology
HSDPA allows the traffic at up to 14.4 Mbps for a single cell
HDSPA enables a single cell to support 15 OVSF codes
Supports RRU cascading
The maximum distance between two RRUs is 40km
The distance from the first one to the last one should be within 100km
When using the 1.25 G optical module, cascading levels is less than 4
When using the 2.5 G optical module, cascading levels is less than 8

Networking BBUs and RNC can form multiple networking modes such as star, chain, tree,
ring, and hybrid
For both chain and tree networking modes:
cascading levels is less than 5
The BBUs in the ring topology require additional transmission equipment.
