– Exam le Flexi confi urations



– Ultrasite configurations





Base station (RF) configuration options

• The main options for the base station configuration are

– Number of sectors/cells

– Number of carriers per sector – Number of Linear Power Amplifiers

▪ E.g. multiple carriers per Linear Power Amplifiers



– near ower mp er transm t power – Base band signal processing capacity

▪ Required signal processing capacity depends on maximum number ofconnections and connection type (bit rate)

Configuration types- Flexi WCDMA/Multimode BTS

• Flexi WCDMA BTS (Rel1 HW) has 3 different basic configuration types

– COC = Cost Optimized▪ 1*Dual RF and 1*Single RF for max 222/20W or 111/40W

▪ can be done also with 2*Dual-RF and 1*Dual RF can be added later for UOC

– UOC = Upgrade Optimized▪ 3*Dual RF for max 2+2+2/40W and beyond

▪ At RU10 we can go up to 444/20W and 222222/20W

– FSC = Feederless Site Configuration▪ 3*Single-RF (or 3*RRH) for max 111/40W or 222/20W



– Rel1-RF can be used with Multimode (Rel2) System Module (FSMC and FSMD)

• Flexi Multimode BTS (Rel2 HW) has 3 different basic configuration types:

– COC▪ 1*Triple RF for max 222/30W or 111/60W

– UOC

▪ 2*Triple-RF for max 222/60W, 444/30W or 222222/30W

– FSC▪ 3*RRH for max 111/60W, 222/30W, 333/20W or 444/15W

• Note: Flexi site is distributed, when one or more RF-Modules are installed to System Module more than

2m apart (However is called “Feederless Site Installation” on Flexi Sales Guide)

COC (Cost Optimized Configuration) has 2 RF modules therefore in case of large distance betweenantennas, RF modules can not be installed close to each of them.

FSC (Feederless Site Configuration) has 3 RF modules therefore they can be located close to each ofthe antennas.

UOC (Upgrade Optimized Configuration) also has 3 dual RF modules therefore has all benefits of FSCand extra capacity.

Flexi BTS 3G frequency bands and carrier power

• Following 3GPP bands already supported (RF Rel1-HW)

– 2100MHz (I), 1900MHz (II)

– 1700/2100MHz (IV),

– 850MHz (V), 900 MHz (VIII)

– 8, 20, 40, 2*20W per TX connector

• 3*70W Triple RF-Module & 70W RRH (RF Rel2-HW) supports

– 2100MHz I in RU10 other bands accordin to roadma /customer re uirements



– LTE support – 8, 20, 30, 60, 2*20, 2*30W, RRH also 3*20W & 4*15W per TX connector

• Lower frequency band dramatically reduces 3G site count

– 850/900MHz can half the number of sites required compared to 2100MHz

– Typically 900/850MHz site grid can be used in re-farming cases

Nearby Obstacles Requirement



Nearby Obstacles Requirement

The most important requirement is that antennas should mounted such that theirmain beams are not obstructed

• In the case of a roof-top site, obstructions could be other antennas or cabinslocated on the same or a neighbouring roof

• In the case of mast or pole mounted antennas, obstructions could be trees ornearby buildings

Why WCDMA Antenna tilt is important



Increased performance by NSNFlexi Tilt

y p

Antenna tilt has impact on network performance

• Cell capacity, own to other cell interference,soft handover overhead and coverage probability

It is important to have whole the time optimal settingfor antenna tilt.

• Remarkable impact on capacityContinuous tilt adjustments are needed

• New sites together with growing or changingtraffic require continuous tilt adjustments


ncrease e c ency or op m za on

• The efficiency of the optimization process can beincreased remarkably by tools and subsystemswhich minimize the number of site visits needed.

Antenna tilt is one of the key parameters in WCDMARAN optimization.

Flexi tilt is a tool for remote networkoptimization.

• Compliant with 3GPP

• NSN Flexi BTS controls the antenna tilt

• Tilt commands are given by BTS element manager

Flexi Tilt supports AISG 2.0



Integrated to BTS :

• Power feed and control for MHAincluding Return Loss measurement

• Lightning protection

• 3GPP standard Antenna Tilt O&M Controlvia Antenna Feeder

• Antenna with Tilt function

• same antenna can be usedwith or without MHA

AISG = Antenna Interface

Standards Group. 3GppAL

interface is defined based

on AISG interface.

Activation without site visit

• AISG protocol with AISG MHA will provide

enhanced alarm information and controlmechanism for MHA functionality.

Module 8 – Configuration planning



Summary

• Flexi BTS can be configured for feederless and distributed

site configurations

• Careful antenna location selection and installation is required

for optimum performance



• WCDMA900 and GSM can use same antenna elements

when multiradio combiner is used in BTS
