1 Introduction to Flexi Multiradio BTS WCDMAThis chapter gives a general overview of Flexi Multiradio Base Station WCDMA.Flexi Multiradio BTS WCDMA is a part of NSN 3G macro BTS site solution. From a BTSsite installation and hardware point of view, Flexi Multiradio BTS introduces a new way tobuild BTS sites using modules, without a specific BTS cabinet. Because of its smallweight and size, modular design and full frontal accessibility, Flexi Multiradio BTS is easyto install in various locations. From a feature and performance point of view, Flexiarchitecture provides a smooth evolution from UltraSite WCDMA BTSs, withoutcompromising performance or capacity.Flexi Multiradio BTS modules can be used with different BTS configurations for anintegrated site solution. The existing site support and auxiliary cabinets can be used tohouse Flexi Multiradio BTS modules, or modules can be installed, for example, on a wall.A Flexi Multiradio BTS consists of three types of RF Modules per frequency band andone System Module with a transmission sub-module. The same Multiradio modules areused in both indoor and outdoor sites.Flexi Multiradio BTS is designed for easy installation, commissioning, and maintenance.One person can carry the modules and install them on the floor or on the wall. Becauseof the modular solution, the footprint, space, weight and power feeding system of the sitecan be optimized. The acquisition time, cost, and acceptance time of a new site isreduced.Flexi Multiradio BTS does not require regular maintenance.

Issue: 12B DN7087165 15

Intelligent BTS ShutdownIntelligent BTS Shutdown with BBU Unit feature optimizes the investment to one batterybackup system on a high-capacity BTS, especially on sites that operate as importanttransmission hub nodes. With intelligent shutdown, separate backup systems for BTSand transmission are unnecessary.The Flexi WCDMA BTS with battery backup system supports an intelligent BTS sitepower shutdown procedure in the event of an AC power failure. During thecommissioning of each site, the operator can define different shutdown timers andpriorities for the BTS sectors and carriers.Intelligent shutdown is activated from Power systems by activating one external alarm(EAC) lines to Flexi BTS.When the Flexi Multiradio BTS detects a problem with the power provisioning – soswitching to battery power supply - an alarm will be raised and the BTS will automaticallyapply mechanism to reduce the required power consumption. By this the Flexi MultiradioBTS will then stay in field as long as the power lasts with reduced or no serviceoffered.When the AC power is getting back, the Flexi Multiradio BTS offers full serviceagain.The reduction of power is done via the stepwise shutdown of services which aretriggered by operator configurable timers per BTS. Different shutdown scenarios can beconfigured for the BTS by setting these timers.Two timers with two different actions are steering the BTS behavior while working onbatteries:

• when the first timer is exceeded, selected number of cells will be switched off (forexample 222 to 111)

• when the second timer is exceeded, all cells of that BTS will be switched offgracefully, means the UEs in that cell will be forced to change to a different cell.

The timer values can be configured via NetAct or with BTS SM.The setting especially of the first timer value shall consider the specific situation in thenetwork.For example, a three-sector two-carrier Flexi WCDMA BTS (2+2+2) site equipped withbattery backup operates as a transmission hub node towards other BTSs in a chain. Thefirst timer can be set to shut down the second carriers of the BTS, to operate as 1+1+1(for example) 30 minutes after an AC power failure. The second timer can be set to shutdown the remaining 1+1+1 BTS (for example) one hour after the AC power failure, inorder to support the transmission node for as long as possible with the existing batterycapacity.Timers can be set according to the configuration and priorities of each site.

Reliable operationSimplicity and speed of maintenance procedures improve operation reliability.Maintenance is improved by module integration and automatic fault detectionprocedures. Special attention has been paid to Flexi Multiradio BTS WCDMA softwarestart time, reducing, for instance, the downtime when a new software package is takeninto use.

6.2 One BTS for all WCDMA network applicationsFlexi Multiradio BTS WCDMA is optimized for high-capacity and wide-coverageapplications. It ensures cell ranges that meet the requirements of the coverageapplications. Therefore, the number of sites required for building a WCDMA coverage issmall. A seamless voice and data coverage area can be built easily.Flexi Multiradio BTS WCDMA has been developed for coverage applications. It offers:

• high downlink power with 100 W Dual RF Module or 210 W 3-sector RF Module,• optimum uplink performance and receiver sensitivity,• outdoor modules that can be located close to antennas, reducing antenna feeder

losses,• optimized antenna system performance, including 3GPP antenna tilting and Mast

Head Amplifier (MHA) support.

Antenna LineOptimized Antenna line is a separate optional site solution to further improve total BTSand antenna system site RF performance and to minimise costs.


Issue: 12B DN7087165 17

Flexi Multiradio BTS WCDMA Optimized Antenna line includes the following optionalfeatures, enabled by SW License keys (for further information, see Licensemanagement):

• Integrated MHA power feeding and O&M control to the RF Module of the Flexi BTS• Antenna line supervision by Return Loss measurement• Integrated 3GPP standard Antenna Tilt power feeding and 3GPP Antenna Tilt O&M

control to the RF Module of the Flexi BTS

Flexi RF Module has an integrated lightning protection circuit in all antenna connectors.The antenna connector of Flexi Multiradio BTS WCDMA is on the RF Module front panel.No additional units, connectors, or jumper cables are necessary between the FlexiMultiradio BTS WCDMA antenna connector and the antenna. This minimizes theantenna line length and losses and optimizes RF performance in both the uplink anddownlink direction.

High-capacity HSDPA and HSUPA BTSFlexi Multiradio BTS WCDMA is a compact high-capacity voice and data BTS designedto support future High Speed Downlink Packet Access (HSDPA) based services andHigh Speed Uplink Packet Access (HSUPA) based services.Smooth HSDPA and HSUPA support is provided through SW. RF and System Modulessimultaneously support existing voice, circuit, and packet data services. They alsosupport HSDPA and HSUPA, meaning that no special HSDPA modules are necessary.The System Module can be used for high bit rates supported by HSDPA software. Theprocessing capacity of the Flexi Multiradio BTS WCDMA can be configured to supportthe maximum capacity that the WCDMA air interface allows.In addition to flexible traffic capacity, Flexi Multiradio BTS WCDMA also allows a free mixof traffic patterns to accommodate whatever proportion of voice and data is required.

3GPP Iub compliant BTSFlexi Multiradio BTS WCDMA is fully compliant with the 3GPP Release 6 Iub standardinterface between the BTS and the RNC. This makes multivendor RAN possible, after3GPP Release 6 telecom Integration and Verification in a multivendor environment hasbeen completed.

Traffic from Flexi Multiradio BTS WCDMA O&M to the NetActTM network managementsystem is carried in IP over ATM. Therefore, all NSN BTS-specific O&M traffic can betransferred transparently to any RNC.

6.3 Flexi Multiradio BTS WCDMA Feederless andDistributed Site conceptFlexi Multiradio BTS WCDMA Feederless and Distributed Site Solutions refer to asituation where the System Module and RF Modules or Remote Radio Heads areinstalled apart from each other.The benefits of the Feederless and Distributed Site Solutions compared to a traditionalBTS site are listed below:

• Overall site RF performance is better compared to traditional installation.• Uplink and downlink performances are 2 - 5 dB better compared with typical 30 - 80

meter long antenna feeders.• The solutions open easier, new and optimized installation possibilities especially with

difficult places.• There is no need for mast head amplifiers.


18 DN7087165 Issue: 12B

Flexi Multiradio BTS WCDMA Feederless and Distributed Site solutions utilise variouspower distribution solutions. DC feed to the feederless or distributed site is providedeither by a NSN power system or third-party products. The input for the System Moduleis floating 48 VDC. There are five basic power supply alternatives for the BTS site and itsmodules:

• Flexi Power Module (FPMA) with a site support module, batteries, and cabinet• FPMA installed in the proximity of the RF Module• FPAB for a single RF Module• Flexi Power Rectifier (FPRx)• third-party AC/DC system (must meet the ETSI 300 132-2 standard)

6.3.1 Feederless siteIn the feederless site solution, the distance between the System Module and the RFModule or Remote Radio Head is up to 200 m, when using preconfigured optical cables.The feederless site solution can be used, for example, on a rooftop BTS site as shown infigure Feederless rooftop site. If the modules are installed on a rooftop, Flexi RF Modulecan be installed very close to the antenna. This enables connecting the RF Module to theantenna with a short jumper cable.When DC is fed from the DC power system (200 m measured from the power systemequipment) to the RF Module or Remote Radio Head, the maximum distance is 200 m.The BTS site can be either DC or AC powered. In the latter case, an AC/DC converter(either the FPMA or a third-party converter) is required.

Figure 6 Feederless rooftop site

DN70161455

Optical cable installation between the System Module and the RF Module or RemoteRadio Head can be done with the following alternatives:

• One 50 m or 100 m optical cable.• By splicing and cutting optical cables on sites where a certain optical cable length is

required.


Issue: 12B DN7087165 19

• By connecting two 50 m and/or 100 m (for 150 m or 200 m) cables using amultimode adapter together with a locally sourced IP55 box.

• Other cable lengths are available for special order (10m, 20m, 30m, 40m, 75m,200m). Only NSN optical cables are allowed.

If a distance longer than 200 m is needed, see Distributed site.

Overvoltage protection is required in installations with a risk of overvoltage by inductionor indirect lightning. This functionality is implemented using Flexi System External OVP(FSEC) or Over Voltage Protection (FSES). Furthermore, the FSEC is used for joining athick long DC cable and the Flexi RF Module or System Module DC cable.Protection level of FSEC/S is 15kA (Class II).

6.3.2 Distributed siteIn the distributed site solution, the distance between the System Module and RFModules or Remote Radio Heads can be up to 15 km. The existing optical fibres can beutilized and equal benefits as in the feederless site concept achieved. The RF Moduleand System Module can be attached to the existing optical fibre network by using a 2 msingle mode optical cable that has IP55 protection in the RF Module and System Moduleend of the cable. Single mode components and single mode transceivers are used forconnecting the System Module to the RF Module. A typical distributed site is a poleinstallation.The power distribution to the RF Module is local and can be either DC or AC (an FPMAnext to the RF Module or a third-party system). Depending on the location of the RFModule, overvoltage protection might be needed. Overvoltage protection is required ininstallations with a risk of overvoltage by induction or indirect lightning. Optionalovervoltage protection functionality (Class II) is implemented using Flexi System ExternalOVP (FSEC) for DC feeding. The FSEC is needed in places where the 3U RF Module orthe long DC feeder cable between the RF Module and FPMA is susceptible to indirectstrokes. Furthermore, the FSEC is used for joining a thick long DC cable and the Flexi


20 DN7087165 Issue: 12B

RF Module or System Module DC cable. Remote Radio Heads have integrated Class IIovervoltage protection, so no external OVP is required at the RF Module end. In case ACinput is used, overvoltage protection has to be carried out locally.

7 Flexi System Module Capacity EvolutionFlexi System Module capacity is designed to support flexible and cost-optimized sitecapacity evolution.Traffic capacityStandard Operating SW of the System Module rel. 1 (FSMB) includes support for 32Channel Elements (CE) to be used for Common Channels.Standard Operating SW of the System Module rel. 2 (FSMC/D/E) includes support forCommon Channels for 6 cells/10 km or 3 cells/20 km.The available baseband capacity of Flexi Multiradio BTS WCDMA can be optimizeddepending on the BTS configuration and the required traffic capacity of the BTS site.More capacity can be enabled by activating HSxPA Processing Set License Keys orRel99 Channel Element License keys.

Processing SetsProcessing Sets are capacity units defined by # users / HSxPA throughput. Licenses forprocessing sets are BTS licenses as any other licenses.HSDPA

• HSDPA BTS Processing Set 1: up to 32Users/7.2 Mbps per BTS• HSDPA BTS Processing Set 2: up to 72Users/21 Mbps per BTS• HSDPA BTS Processing Set 3: up to 72Users/84 Mbps per BTS

HSUPA

• HSUPA BTS Processing Set: up to 24Users/5.8 Mbps per LCG

HSPA licensing is valid for Flexi System Modules FSMC/D/E.

8 Management and software

8.1 Local Management ToolWCDMA BTS Site Manager software is used to manage Flexi Multiradio BTS WCDMAcommissioning, supervision, maintenance, and testing, as well as transmissionconfiguration.

Figure 8 WCDMA BTS Site Manager main view

Flexi Multiradio BTS WCDMA site can be controlled remotely by opening a WCDMA BTSSite Manager session at a remote RNC/Flexi Direct RNC or NetActTM site.The manager PC is connected to the BTS by means of an Ethernet connection locally atthe site or remotely by specifying the IP address in the Site Manager.The site manager SW package includes the following:

Flexi Multiradio BTS WCDMA Product Description Management and software

Issue: 12B DN7087165 23

• The WCDMA BTS Manager including antenna line and antenna equipment controland management

• The FlexiTransport Manager, for transmission management

WCDMA BTS Site Manager runs in the following environments:

• Microsoft Windows 2000, XP, Vista, and 7• Windows Server 2003• Red Hat Enterprise Linux 4 ES GNOME desktop

Flexbus-related configurations are performed with FlexiHub Manager.

8.2 Configuration managementOnce the BTS is in normal operation, a polling process is used to check possiblechanges in the BTS configuration. When modules are added to or removed from theBTS, the information in the HW database changes.

8.3 Remote User Event Log ManagementRemote User Event Log Management (RUEM) is a feature that allows a networkmanagement system (NMS) to trace operations done in network elements (NEs) bydifferent users. This functionality is sometimes called “Audit Trail”. User access andoperations might be successful or fail and in both cases this is logged.

Figure 9 Audit trail

With RUEM, operations are logged on FTM/FCT and sent to NetAct within one singleRUEM log file.NWI3 logged operations:

• Login attempts (successful + unsuccessful)• Logout• Configuration changes (on fragment level)• Local account updates

HTTP logged operations:

• Reboot operations• Reset to factory default operation

XoH logged operations:

• SW Management (SW update Request and SW interrupt)• Object Configuration Management (for example ResetRequest)• License Update/Deletion Request• Alarm Management and Diagnostics (for example Change Direct Access Status)• Test Management (for example Test Dedicated State Request)• User Management (for example Login and Modify User Request)• Commissioning (for example Parse Commissioning Data Request)• Clock Operation Request

8.3.1 RUEM concept - how does it work?RUEM correlates each management operations with each user:

• NWI3 and XOH management operations implements session concept(username/password)

• HTTP operations which are logged is operations which required username/password

Figure 10 The RUEM concept

Notification - WatermarkOperations that are logged by RUEM are stored in FTM/FCT in a ring buffer(internally).This buffer is filled up for each logged operation.As soon as a critical value (that is watermark, ~70% of total buffer size) is reached,FTM/FCT sends a notification to NetAct (mediated by OMS in Flexi).

The RUEM upload mechanism1. Triggered by NetAct


Issue: 12B DN7087165 25

2. Triggered by Network element (FTM/FCT) - if the Watermark level is reached

After a successful reading of the logfile by the NMS the read logfile is deleted from theBTS to free memory space for the next log entries. Log files in the BTS are kept in non-volatile memory and thus data is not lost upon power breaks.Exception: In case NetAct still does not upload the RUEM log file, the buffer might fill upto its maximum size and even exceed this. In latter situation the buffer has an overflow,some old information gets lost permanently. It is not recoverable! This special eventcalled as wrapped-over event. This should be logged in RUEM log file.

8.4 Software updatesFlexi Multiradio BTS can store two software packages in its memory. The software canbe loaded either locally, with the BTS Site Manager software, or remotely from NetActTM.Site visits are unnecessary for routine O&M tasks.

Typically, local software downloading is done only when the NetActTM connection ismissing, such as during commissioning. Flexi Multiradio BTS software can bedownloaded as a background operation without interrupting the operation of the BTS.The new software can be activated at any time. Reboot is required in order to take thesoftware into use.Flexi Multiradio BTS only uses downloadable software. All software can be downloadedand updated from NetActTM. This procedure is centralised, meaning that several BTSscan be upgraded with the new software either simultaneously or one by one.Flexi Multiradio BTS keeps the current and old software packages in its flash memory.Either of these software versions can be activated at any time. Reboot is required inorder to take the software into use. Updated softwares (current and previous) in the BTScan be seen through BTS Site Manager/NetActTM.

8.5 External alarms and controlsElectrically, Flexi Multiradio BTS WCDMA provides external alarms and controls similarto UltraSite WCDMA BTS.The BTS alarms and control inputs and outputs can be configured and tested locally atthe BTS site with WCDMA BTS element manager SW. Up to 24 user-definable externalinputs and six (6) user-controllable outputs are available and can be freely configuredduring commissioning to support different observation or control needs at the BTS site.Flexi System External Alarm (FSEB) should be used if old UltraSite or TalkSite alarmconnections, or more than 12 alarm inputs, are used. If control outputs are used themaximum cable length is 15 m (49.2 ft).In normal operation, the BTS’s external alarms and control outputs are managed fromNetActTM after they have been configured. External alarms and control outputs areavailable from the System Module but not from the Extension System Module.

8.6 SW upgrade and licensingRegular SW upgrade does not have an impact on the existing license files in networkelements. The old functions work with the old license files.For new functions that are introduced with the new SW release, corresponding licensefiles must be obtained and distributed to the network elements to activate the feature.In later releases, license files can be distributed to the network elements before the SWrelease upgrade. New license files are taken into use only when the corresponding SWrelease is activated in the network element.

g A topology upload is needed so that the Network license Manager applicationreceives the correct target identifiers to be used in licensing.

g The lack of a license does not affect the (remote) management access to thebase transceiver station (BTS) in the field. Missing licenses might causeinterruption to the services after the software upgrade.

9.2 MechanicsAll Flexi Multiradio BTS modules are outdoor-capable, weather-sealed and at least IP55class protected. Flexi Multiradio BTS modules consist of the following main parts:

• Module core. The core mechanics, with installed gaskets in all of the connectors,shield the module core against water, snow, and solid foreign objects, and make themodule core IP65 weatherproof. The core mechanics also provide EMC shielding.

• Module casing. This provides fixing points for modules to the plinth and supports thestack of modules. The module core can be changed even if the module is at thebottom of the module stack.

• Fan assembly. This provides fresh air to cool the module. Each module controls itsown fans according to temperature information, and two redundant fans enablemodule operation at normal temperatures, even with one fan. The fan sub-modulecan be changed in an operational module at a site where back access is provided.

• Module cables. All cables are IP55 protected.• Optional Front and Back covers for BTS site installations without a cabinet.

or• Optional cabinets:

Iub connection to RNC (Transmission connectors)The connectors for the Iub are located on the front panel of the transmission sub-module(FTxx). The cables are routed to the side of the System Module.

BTS Element Management port (LMP)An Element Manager PC can be connected to the management port connector at theSystem Module, for commissioning, operations, maintenance, and testing of the BTS. AnRJ45 Ethernet connector is used.

Antenna connectors (Ant 1-6)The antenna feeders are connected directly to the RF Modules. With three dual poweramplifier RF Modules the maximum number of antenna connections is 12. The antennaconnector type is 7/16 .

Ethernet control busThese interfaces can be used to carry initialisation data, control data, and signalling datafrom the BTS to any auxiliary equipment that has an Ethernet port and an IP address.

Power feeding (Power supply connectors)A Flexi Multiradio BTS site has one common DC input power supply that is connected tothe System Module. The System Module distributes DC current to the RF Modules andto a second System Module operating in baseband extension mode. The AC connectoris at a separate optional AC/DC Module.

External alarms and controls (EAC)One EAC connector is located at the System Module. A separate weather-protectedEAC connector box (FSEB) can be used to ease the connection of each physical alarmand control wire.One optional Flexi System OVP IP55 protected box for power lines (FSEC) can be usedto weather protect overvoltage protectors (OVP) of the DC or AC power lines of the BTSsite.

External Synchronization Input (Sync in)When using this hardware connector, Flexi Multiradio BTS WCDMA can be optionallysynchronized with an external clock signal (for instance GPS, 2 or 10 MHz signal) whenIub transport is not providing clock reference signal, for instance, when Iub over Ethernetdoes not carry clock reference.

External Synchronization Output (Sync out)Flexi Multiradio BTS WCDMA can provide clock reference signal to other co-located BTSnearby (2G, 3G and future BTS).

10 GSM/EDGE and WCDMA co-sitingFlexi Multiradio BTS WCDMA is designed so that it is compatible with existing BTSs andit is easy to install on an existing site.

MechanicsFlexi Multiradio BTS WCDMA modules have much smaller space requirements thanthose of the Talk family and UltraSite EDGE/WCDMA BTSs. Floor installations ofmodules can be done using the same fixing points.

Power systemWhen Flexi Multiradio BTS WCDMA is installed to an existing GSM/EDGE BTS site, thesame connection types and power supply types can be used. The existing alarmconnections, for example, the fire alarm and door alarm, can also be connected to FlexiMultiradio BTS WCDMA.

AntennasTo minimise the work in adding WCDMA antennas to GSM BTS sites, part of the existingantenna infrastructure can be reused.A diplexer is an attractive way to add the Flexi Multiradio BTS WCDMA to the existingsite, if the additional loss can be tolerated in the antenna line. Actual losses depend onthe combination but (for example) in the case of GSM 900/WCDMA, the typical loss isless than 0.5 dB. NSN supplies diplexers for all necessary combinations.The Multi Radio Combiner (MRC) solution makes it possible to build an antenna linesharing site with a minimum effect on existing system performance. Downlink causesonly a slight degradation for the BTS performance. A typical downlink loss is less than0.6 dB. The Mast Head Amplifier (MHA) retains the uplink performance.There are three different MRC units that cover the bands: 850 MHz, 900 MHz and 2100MHz. The MRC 850 and MRC 900 units give the possibility to co-siting GSM EDGE andWCDMA BTSs in the same frequency band through antenna line sharing. There are nolimitations to system frequency allocation (G-G-W, G-W-G, W-G-G). The MRC 2100 unitallows WCDMA and WCDMA BTSs co-siting in the same frequency band throughantenna line sharing. Using MRC units makes it also possible to co-site third-party BTSs.

Flexi Multiradio BTS WCDMA mounting kits for GSM/EDGE BTSFlexi Multiradio BTS WCDMA modules can be installed inside an existing GSM/EDGEcabinet. The following mounting kits are available for that purpose:

• Talk Conversion Kit (EMIA/EMIB)• Flexi Mounting Kit Vertical for 2G (FMUA)• Flexi Mounting Kit Horizontal for 2G (FMUB)• Flexi Mounting Kit for WODA (FMUH)• Mounting Kit for NB Flexi Outdoor (FMUG)• Mounting Kit for WREB (FMUJ)• 4U Mounting Kit for UltraSite EDGE (FMUM)
