Flexi Multiradio 10 Base Station Product Description Benefits

Id:0900d805809d37c7Confidential

6 Benefits

6.1 Cost-efficient modular siteWith Flexi Multiradio 10 Base Station, the same equipment can be used to build coverage and capacity. A high cell capacity and wide coverage per site means fewer sites which makes building a network more cost-effective. Flexi Multiradio 10 Base Station can be installed at any existing legacy GSM/EDGE/CDMA/WCDMA site for a broadband data capability upgrade. Flexi Multiradio 10 Base Station is designed to utilize the existing site equipment.

Easy installationA Flexi Multiradio 10 Base Station module can be lifted, carried, and put in place by one person. The average module installation time is reduced, compared to traditional cabinet BTSs.

Flexi Multiradio 10 Base Station can be installed on a wall, however, it fits in the existing legacy Nokia Siemens Networks GSM/EDGE/CDMA/WCDMA BTS footprints as well. Each Flexi Multiradio 10 Base Station module is protected to at least IP65 level and can be installed as such at an outdoor site. In addition, both indoor and outdoor cabinet installation options are available. Installation locations for a Flexi Multiradio 10 Base Station can be smaller than or the same as those reserved for previous Nokia Siemens Networks BTSs.

Low acoustic noiseThe acoustic noise produced by a Flexi Multiradio 10 Base Station site is low because of reduced power consumption and an increased unit integration level. Site acceptance is easier, especially at urban outdoor sites. Fan speeds and acoustic noise are adapted to the BTS load and ambient temperature.

Easy commissioningThe autodetection feature of Flexi Multiradio 10 Base Station makes commissioning and integrating fast and easy. The commissioning wizard guides the user step-by-step through the whole commissioning process. At the end of the process, the commission-ing wizard produces a BTS Commissioning Report.

Reliable operationSimplicity and speed of maintenance improves operational reliability. Maintenance is improved by module integration and automatic fault detection procedures. Special atten-tion has been paid to Flexi Multiradio 10 Base Station software start time, reducing, for instance, downtime when a new software package is put into use.

Intelligent shut-downIntelligent shut-down feature optimizes the investment to one battery backup system on a high-capacity BTS, especially on sites that operate as important transmission hub nodes. With intelligent shut-down, separate backup systems for BTS and transmission are unnecessary.

Flexi Multiradio 10 BTS with battery backup system supports an intelligent BTS site power shutdown procedure in the event of an AC power failure. During the commission-ing of each site, the operator can define different shutdown timers and priorities for the BTS sectors and carriers.

18 DN0971928



Benefits

Intelligent shutdown is activated from Power systems by activating one external alarm (EAC) lines to Flexi BTS.

When Flexi BTS detects a problem with the power provisioning - so switching to battery power supply - an alarm is raised, and the BTS automatically reduces the required power consumption. In result, Flexi BTS is operating with reduced or no service offered as long as there is enough power. Once the AC power is restored, Flexi BTS again offers full service.

The reduction of power is done via the stepwise shutdown of services which are trig-gered by operator configurable timers per BTS. Different shutdown scenarios can be configured for the BTS by setting these timers.

Two timers with two different actions are steering the BTS behavior while working on batteries:

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

• When the second timer is exceeded, all cells of that BTS will be switched off grace-fully, 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 the network.

For example, a three-sector two-carrier Flexi Multiradio 10 BTS WCDMA (2+2+2) site equipped with battery backup operates as a transmission hub node towards other BTSs in a chain. The first 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 shut down the remaining 1+1+1 BTS (for example) one hour after the AC power failure, in order to support the transmission node for as long as possible with the existing battery capacity.

Timers can be set according to the configuration and priorities of each site.

6.2 One BTS for all network applicationsFlexi Multiradio 10 Base Station is optimized for high-capacity and wide-coverage appli-cations. It ensures cell ranges that meet the requirements of the coverage applications. Therefore, the number of sites required for building a good coverage is minimized. A seamless voice and data coverage area can be built easily.

Flexi Multiradio 10 Base Station has been developed for coverage applications. It offers:

• Wide variety of RF modules for different applications and use cases, for example high downlink power with Flexi 3-sector 240 W RF Module.

• Support of 2Tx MIMO 40+40 W per sector with single 6Tx RF Module and 4Tx MIMO 40+40+40+40 W per sector with two 6Tx RF Modules.

• 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

masthead amplifier (MHA) support. • High downlink power in small size with Flexi Remote Radio Head.

w NOTICE: Masthead amplifier (MHA) is not supported in TD-LTE.

Antenna lineOptimized Antenna line is a separate, optional site solution to additionally improve total BTS and antenna system site RF performance and to minimize costs.

Flexi Multiradio 10 Base Station Optimized Antenna line includes the following optional features, enabled by SW licenses:

• Integrated MHA power feeding and O&M control to the RF Module of the Flexi BTS. • Integrated Antenna line supervision by Return Loss measurement (VSWR measure-

ment). • 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 10 Base Station is on the RF Module front panel. No additional units, connectors, or jumper cables are necessary between the Flexi Multiradio 10 Base Station antenna connector and the antenna. That minimizes the antenna line length and losses, as well as optimizes RF performance in both the uplink and downlink direction.

High speed broadband data and high capacity voiceFlexi Multiradio 10 Base Station is a compact multi-purpose BTS designed to support all future high speed broadband data and voice services over an air interface. Smooth data and voice capacity evolution is provided through software.

The processing capacity of Flexi Multiradio 10 Base Station can be configured to support the maximum capacity that the air interface allows.

In addition to the flexible traffic capacity, Flexi Multiradio 10 Base Station also allows a free mix of traffic patterns to accommodate whatever proportion of voice and data is required. Depending on network capacity requirements, the capacity installed can be matched with the capacity of the air interface.

6.3 Feederless and Distributed Site conceptStandard Flexi Multiradio 10 Base Station modules support the Feederless BTS site application where one RF Module or Remote Radio Head or the entire Flexi BTS is installed close to the antennas. For a feederless site, traditional long antenna feeders or masthead amplifiers are not needed thanks to which the BTS site RF performance is optimized in both uplink and downlink.

The benefits of Feederless sites are:

• Better RF performance because there are no downlink and uplink feeder losses. • Easier installation because of reduced cabling to the tower. • No long antenna feeders (typically six for a three-sector site). • No masthead amplifiers/tower-mounted amplifiers. • Reduced total wind load and weight. • Reduced total power consumption.

RF Module and Remote Radio Head can be software-activated and configured to support one, two, or three sectors, or one sector with 2TX MIMO with optional four-way uplink diversity.

In the Distributed Site solution, RF Module(s) or Remote Radio Head(s) are located up to 20 km away from the main Flexi System Module site.

Single RAN aspects

7 Single RAN aspects

7.1 RF sharingThe RF sharing feature allows Flexi Multiradio BTS RF Module to operate in a concur-rent mode with two radio access technologies (RATs). BTS resources between RATs are allocated and shared by allowing two Flexi EDGE/WCDMA/LTE System Modules to share the same Flexi BTS Multiradio RF Module or Remote Radio Head (RRH). RF Module or RRH is transmitting RF carrier signals for two or more RATs at the same fre-quency band. The RF Sharing concept simplifies the antenna system complexity, and provides the operators with future-proof BTS site evolution.

Flexi Multiradio 10 Base Station Product Description Single RAN aspects


Figure 7 Transport sharing in multiradio BTS site

The BTS site backhaul traffic can be aggregated on one integrated IP/Ethernet interface by utilizing integrated QoS aware Ethernet switching. Synchronization Hub feature can be used for reference clock distribution on the BTS site.

QoS Aware Ethernet SwitchingQoS Aware Ethernet Switching allows multiple Ethernet interfaces in the BTS to be con-nected through the integrated Ethernet switch. One of the interfaces is used for the backhaul connection, while others might be used to connect other BTSs (at the same or another site). It is also possible to daisy chain several network devices.

The Ethernet switch is VLAN- and QoS-aware. The egress traffic of the switch can be shaped to meet the bandwidth limitations of the backhaul network. Additionally, a policy can be applied to the ingress traffic to protect the BTS from the interface overload.

g Ethernet switching is required at the BTS where the layer 2 traffic aggregation/daisy chain is to be implemented.

Synchronization HubEach System Module can act as a synchronization hub for other near-located System Modules. For example, it can output 2.048 MHz SynchOut based on any available syn-chronization source. If PDH interfaces are available in the System Module, then they can also be used for synchronization distribution to other devices.

Flexi Multiradio 10 Base Station Product Description Baseband capacity

Id:0900d80580a23af6Confidential

8 Baseband capacityBaseband capacity by SW licenseFuture-proof Flexi Multiradio System Module capacity is designed to support flexible and cost-optimized site capacity evolution. The highest capacity Flexi System Module is dimensioned to provide a hardware baseband capacity, for example, for up to three 20 MHz LTE cells (FSMF).

Baseband capacity of Flexi Multiradio 10 Base Station can be optimized depending on the BTS configuration and required traffic capacity of the BTS site. More baseband capacity can be allocated remotely from NetAct™ by sending a Baseband SW License to Flexi Multiradio 10 Base Station. Flexi Multiradio 10 Base Station baseband capacity can be optimized in steps of Mbit/s without a site visit.

Future capacity evolutionFlexi Multiradio 10 Base Station is future-proof designed to support future capacity demand. The Flexi BTS architecture supports baseband pooling of two System Modules, making it possible to build high capacity sites. Flexi Multiradio System Module provides space for up to two baseband extension sub-modules (FBBA) that enable three times the capacity of the Flexi Multiradio System Module.

SRIO and OBSAI RP3-01 interfaces provide connectivity for baseband capacity and/or technology extension. Baseband extension and related interface utilization depends on the radio access technology and the use case (a pure new Flexi Multiradio System Module case or an existing Flexi System Module case).

Table 1 Maximum capacity of Flexi Multiradio 10 Base Station shows radio access tech-nology–specific capacity details.

Management and software

9 Management and software

9.1 Local Management ToolThe BTS Site Manager software is used to manage Flexi Multiradio 10 Base Station commissioning, supervision, maintenance, and testing, as well as transmission config-uration.

Figure 8 BTS Site Manager main window

A Flexi Multiradio 10 Base Station site can be controlled remotely by opening a BTS Site Manager session at a remote NetActTM site.

The site manager software package includes the following:

• Flexi Multiradio BTS Manager, including antenna line and antenna equipment control and management;

• FlexiTransport Manager, for transmission management; • Site Support Manager, for power and battery backup system.

DN0971928 29

Flexi Multiradio 10 Base Station Product Description Management and software


These managers are integrated so that the physical interface (cable and connectors) is the same in all three cases, however, three different applications run on the PC. The manager PC is connected to the BTS by means of an Ethernet connection.

BTS Site Manager runs in the following environments:

• Microsoft Windows XP, Vista, and 7 (32/64 bits) • Microsoft Windows Server 2003 and 2008 • Red Hat Enterprise Linux 4 ES GNOME desktop

30 DN0971928


Id:0900d80580988f69Confidential

9.2 Configuration managementOnce the BTS is in normal operation, a polling process is used to check possible changes in the BTS configuration. When modules are added to or removed from the BTS, the information in the hardware database changes.

DN0971928 31


Id:0900d80580993ebfConfidential

9.3 Remote User Event Log Management Remote User Event Log Management (RUEM) is a feature that allows a network man-agement system (NMS) to trace operations done in network elements (NEs) by different users. This functionality is sometimes called “Audit Trail”. User access and operations might be successful or fail. In both cases this is logged.

Figure 9 Audit trail

With RUEM, operations are logged on Flexi Baseband Controller (FCT) and sent to NetAct within one single RUEM log file.

NWI3 logged operations:

• Login attempts (successful and 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) • Licence 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

9.3.1 RUEM concept - how does it work?RUEM correlates every management operation with each user:

• NWI3 and XOH management operations implement session concept (user-name/password)

• HTTP operations which are logged are operations that require username/password

32 DN0971928



Figure 10 The RUEM concept

Notification - WatermarkOperations that are logged by RUEM are stored in 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, FCT will send a notification to NetAct (mediated by OMS in Flexi).

The RUEM upload mechanism

1. Triggered by NetAct

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

After a successful reading of the logfile by the NMS, the read logfile is deleted from the BTS to free memory space for next log entries. Log files in the BTS are kept in non-volatile memory, and thus data is not lost upon power breaks.

DN0971928 33



Exception: In case NetAct still does not upload the RUEM log file, the buffer might fill up to its maximum size and even exceed this. In the latter situation the buffer has an overflow and some old information gets lost permanently. It is not recoverable. This special event is called a wrapped-over event. This should be logged in RUEM log file.

34 DN0971928


Id:0900d80580993ecbConfidential

9.4 Software updatesFlexi Multiradio 10 Base Station can store two software packages in its memory. The software can be loaded either locally, with the BTS Site Manager software, or remotely from NetActTM. Site visits are unnecessary for routine operation and maintenance (O&M) tasks.

Typically, local software download is done only when the NetActTM connection is missing, for example, during the commissioning process. Flexi Multiradio 10 Base Station software can be downloaded as a background operation without interrupting the BTS operation. The new software can be activated at any time. Reboot is required in order to put the software into use.

Flexi Multiradio 10 Base Station only uses downloadable software. All software can be downloaded and updated from NetActTM. This procedure is centralized, meaning that several BTSs can be upgraded with the new software either simultaneously or one by one.

Flexi Multiradio 10 Base Station keeps the current and previous software packages in its flash memory. Either of these software versions can be activated at any time. Reboot is required in order to put the software into use. Updated software (current and previous) in the BTS can be seen through BTS Site Manager/NetActTM.

The RF Module and RRH SW is updated automatically during Flexi Multiradio 10 Base Station SW update.

DN0971928 35


Id:0900d80580993ed1Confidential

9.5 External alarms and controlsBTS inputs and outputs can be configured and tested locally at the BTS site with Flexi Multiradio BTS Site Manager software. Six user-defined external inputs and six user-controlled inputs/outputs are available and can be freely configured to support various observation or control needs at the BTS site.

In normal operation, the external alarms and control outputs of the BTS are managed from NetActTM after they have been configured.
