After completing this module, the participant will be able to:Theory / Practical:• List the Antenna System products• Describe Antenna cable installation• Describe the functionality of a Bias T and Mast Head Amplifier (MHA)• Describe the advantages of the FLEXI WCDMA BTS feederless system


Antenna System Products

• Antenna• WCDMA Dual MHA (Masthead Amplifier)• Bias-T• Diplexer (dual-band combiner)• Triplexer (triple-band combiner)• Feeder cable• Connector for feeder cable• Jumper cable• Grounding kit• Cable fixing kit (clamps and hangers)• EMP protector if required• Real Tilt


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 it’s 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


Antenna Systemconfiguration example:BTS with Dual MHAand Bias-Ts

In Flexi WBTS, the Bias-Ts are integrated to the RF Module FRxx.


Antenna Systemconfiguration example:Dual Band BTS with Dual MHAand Bias-Ts


Bias-T (for UltraSite/MetroSite)

• Two functions:• 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.

• IP 65• Size: W x L x D: 48 x 91 x 48 mm• Weight: 0.4 kg• VSWR Alarm level: Return loss 7 dB

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


Versions:• WMHA

• single MHA• 12 dB gain

• WMHB• Dual MHA• 2 single MHAs in one mounting frame• 12 dB gain

• WMHC• Dual MHA• 2 MHA functionalities in a common enclosure• 12 dB gain• DC power supply through “BTS 2” port only.

Flexi WBTS antenna configuration examples


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.
