Flexi WBTS antenna system features

Integrated VSWR Bias-T
Integrated MHA power feed and supply current monitoring circuit.
Future releases
Support for BTS integrated antenna tilt control
Support for Control a mast head amplifier
In WN3.2 we have non-intelligent MHAs, only controlled by the power and current
alarms are possible
In WN4.0 its possible to control also active MHAs (AISG/3GPP). E.g. the gain mode /
level is possible to select by the SW, alarms from MHA, etc.
Update/upgrade a software of such devices WN3.2 only filter

Bias-T (for UltraSite/MetroSite)

Two functions:
VSWR version WBVA
DC power feed to MHAs through

center conductor of the feeder
VSWR monitoring (optional)
WBVx with VSWR monitoring

WBNx without VSWR monitoring
In case the VSWR threshold is
exceeded, the Bias-T sends an alarm
to the BTS.
In Flexi WBTS, the VSWR Bias-T is
integrated to the RF Module FRxx.
both functions, power feed to MHA
and VSWR monitoring are licensed
features.

Mast head amplifier

General purpose
Amplifies RX (uplink) signals
Is an active device, requires power supply
Reduces system noise figure
Increases uplink capacity
Compensates for feeder and combiner losses in the up-link direction, increasing
coverage for suburban, rural and road sites where antennas are in very high
positions and the feeder lines are long
Reduces interference caused by non-WCDMA mobile phone users
Allows mobiles to reduce transmission power level
Improves mobile station battery lifetime

Flexi with Nokia RealTilt, before RAS06

On the following pages some supported configuration alternatives shown with the Flexi NodeB
and the
existing Nokia RealTilt System.
These configurations can also be used when the Flexi NodeB is upgraded to RAS06, if the Flexi
RET SW is not taken into use.
The Nokia Control Unit (RCUA or RCUO) requires an Ethernet connection to the Flexi NodeB, so
that the RET system can be
controlled from the BTS Element Manager.
The Nokia Control Unit (RCUA or RCUO) can be 48VDC powered from the Flexi NodeB.

Following RealTilt items needed in this configuration
(alt.1):
(Note: Only one sector shown in the picture)
- RET antenna
- External RTA (related to antenna type)
- Lightning Protection Device, 469833A (RLPA)
- RCUA or RCUO
469757A - Control Unit (RCUA)

Flexi with Nokia RealTilt , from RAS06

On the following pages some supported configuration alternatives shown with the Flexi NodeB
and the existing Nokia RealTilt items.
These configurations are based on that the Flexi RET SW has been taken into use.
In Flexi NodeB RET SW, each sector has its own separate RET control over the feeder.
