Features of the DBS3900
2.1 Coverage Capability
The DBS3900 has the following benefits in terms of coverage:
The RRU3004 supports the cascading of three RRU modules. One RRU module
can be placed 40 km away from the BBU.
High receive sensitivity: The static sensitivity of the TCH/FS is -113 dBm (typical
value in normal temperature).
Power Boost Technology (PBT) is supported by RRU3004.
The maximum output power (TOC) of the RRU3004 can reach up to 40 W (900M)
or 30 W (1800M).
A maximum of 12 cells can be configured and multi-band networking is
supported.
Antenna hopping and transmit diversity are supported.
2.2 Capacity
One RRU3004 provides two transceivers and two assembled RRU3004s provide
four transceivers.
72 transceivers are supported by BBU3900.
Abis over IP is available.
2.3 Networking Capability
E1/T1, FE optical, microwave and satellite transmission are supported.
Star, tree, chain, ring, and hybrid topologies are supported.
Flex Abis networking is supported.
The GSM and UMTS can share the BBU3900.
The transmission on the Abis interface is optimized. The detection and
restoration of idle frames on the BTS and BSC side are supported. However, no
idle frames are transmitted over the transport lines to save the transmission
bandwidth.
