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

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

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

Operating band: 880 915 MHz Compatibility:
NSN Flexi WCDMA BTS with NSN EDGEbase stations Other vendor 3GPP-compliant base stations
(on a separate agreement)
Operation principle: Combiner unit with filters Allows the use of remote antenna tilt
Mechanics: NSN Flexi BTS module mechanics 1.5 HU without casing, 2 HU with Flexi casing
Performance: Downlink loss: WCDMA 0.5 dB, GSM 0.5 dB Uplink loss: 4 dB, can be compensated with MHA
Mechanics: NSN Flexi BTS module mechanics Installation: Stack, wall or pole mounted, or in 19 racks Can be installed indoors or outdoors, IP67 Dual Mast Head Amplifier for 900 MHz (MDGA)
is recommended to be used together with FlexiMultiradio Combiner to compensate uplink loss.
Other frequency variants:850 MHz, 1800 MHz, 1900 MHz

Summary
Flexi BTS can be configured for feederless anddistributed 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
