Table 1 Ethernet Transport Media
Signal distribution between other entities (e.g. BTS-POI, POI-BSI, and RRH-antenna) is
realized by RF connection.
It is possible to operate WLAN on the same physical infrastructure
depending on the ClearFill®Star-CDMA system, as long as the system
performance of both VLANs (ClearFill®Star and WLAN) is not degraded.
2.3 Features
2.3.1 General Features
A BSI / RRH supports one single CDMA RF carrier. It provides sufficient rejection
against adjacent carriers.
The system uses Ethernet protocol for the communication between BSI, RRH and
switches.
The summing function summarizes the capability to transform a number of incoming
independent data streams in a single data stream.
The RRH contains a summing function. It combines in UL the data stream of up to 8
RRHs (7 RRH + itself).
The BSI contains a summing function. It combines in UL the data of up to 8 data
streams.
The maximum number of supported RRHs in a system configuration with one BSI is
16.
The system supports 2 summing levels (1x BSI, 1x RRH).
The transport network consists of up to 4 cascaded GES.
It is possible to install a pre-configured RRH in a running system (e.g. when a RRH is
disconnected and re-connected afterwards).
A RRH, which has not been configured, will initialize in the NMS and start-up in idle
mode with default values (factory settings). It starts in online mode without
transmitting.
It is possible to adjust the maximum output power of the RRH via the NMS and
remote control of the NMS in 1 dB steps.
The system is capable to upload new SW releases via the network management
center.
Ethernet network operates via CAT5- or fiber links both supporting data rates of
1Gbit/s.
The monitoring and configuration of the network elements is realized by the NMS.
