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

Linear Power Amplifier transmit power

Base band signal processing capacity Required signal processing capacity depends on maximum

number of connections 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 Modulemore than 2m apart (However is called Feederless Site Installation on Flexi Sales Guide)

Flexi BTS Configuration Types

RAS5.1ED,WBTS3.3

COC (Cost Optimized Configuration) has 2 RF modules therefore in case of large distancebetween antennas, 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 toeach of the antennas.

UOC (Upgrade Optimized Configuration) also has 3 dual RF modules therefore has all benefitsof FSC and 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 according to roadmap/customer requirements

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

WAM (Wideband Application Manager):

There may be up to six WAM units installed in the BTS,

- 3 WAMs act as primary WAMs (WAM in slots Nr. 0)

- 3WAMS act as secondary WAMs. (WAM in slots Nr. 1).

- 6 WAM support (max.18 WSP cards in Supreme and 12WSP in Optima )

One primary WAM at a time is selected as a Telecom andO&M master unit (Master WAM) by the system.

Master WAM-unit takes care of the control functions onBTS cabinet level. Those include BTS start-up,temperature control, configuration and O&M processing.

All WAM units perform telecom control functions, logicalresource management, ATM processing and transport

channel frame protocol processing.

50/74RN31549EN10GLA0

Nearby Obstacles Requirement

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

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

In the case of mast or pole mounted antennas, obstructions could be treesor nearby buildings

Poor Position Good PositionPoor Position Good Position


51/74RN31549EN10GLA0

Roof-top installation

As the antenna position is moved away from the edge then

the antenna is more likely to incur shadowing Antennas which are located away from the edge should be

mounted with an increased height

Increased performance by NSN

Flexi Tilt

Why WCDMA Antenna tilt is important

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

Increased efficiency for optimization

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 WCDMA BTS 3GPP Antenna Tilt Support

Antenna Tilt is integrated to the RF moduleof Flexi BTS. It feeds DC power to theantenna and controls the antenna tilting.

In Flexi BTS this 3GPP specified antennatilting functionality must be enabled by a SWlicence because the HW is integrated to allRF Modules.
