3.1.3 RF power and sensitivity for microcellular applications
The RF performance of the Nokia MetroSite EDGE Base Station is suitable for
microcellular, building infill and roadside coverage applications. The maximum
RF power of the Nokia MetroSite EDGE Base Station transmitter is 5 W at the
antenna connector. The maximum RF power of the Nokia MetroSite EDGE Base
Station in EDGE modulation mode is 3.2 W. The RX sensitivity is better than -
106 dBm. The output power and the receiver sensitivity of the Nokia MetroSite
EDGE Base Station, together with the use of surrounding buildings to limit the
cell size, allow efficient frequency re-use with minimised interference.
The dynamic power level range of the transmitter and the static broadcast control
channel (BCCH) power level range are shown in Table 1.
3.1.4 Smooth capacity expansion
As the operator’s demand for capacity grows, additional TRXs can be installed to
the Nokia MetroSite EDGE Base Station during operation without interrupting
the BTS service.
3.2 High network quality
The Nokia MetroSite EDGE Base Station increases the capacity of the network
and also maintains the quality of telecommunication traffic. This section
describes the features that contribute to the high network quality.
3.2.1 Receiver diversity
Receiver diversity (also known as uplink diversity) is available in the Nokia
MetroSite EDGE Base Station when two or more TRXs belong to the same
sector.
