7 Benefits
7.1 Cost-efficient modular site
With 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.
Low site rental costs
Flexi Multiradio 10 Base Station reduces BTS site rental costs because a BTS-specific
cabinet or extra floor space is no longer needed on the site. However, existing sitesupport and auxiliary cabinets can be used to house Flexi Multiradio 10 BTS modules.The modules can be also installed on a wall.
Low total site power consumption
Because of the high integration of Flexi Multiradio 10 BTS and the advanced power
amplifiers the overall power consumption is decreased. In typical configurations, the
power saving is up to 60% compared to the first generation of WCDMA BTS. Additional
benefits are:
smaller battery capacity for the same backup time
less AC-DC rectifiers
smaller fuses and thinner power feeding cables air-conditioning for indoor sites needed only in special cases
no air-conditioning for outdoor sites
no need for a dedicated cabinet for the power system and auxiliary equipment
Easy installation
A 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, poll, or floor. It fits in the
existing legacy GSM/EDGE/CDMA/WCDMA BTS footprints as well. Flexi Multiradio 10
BTS outdoor 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 BTSs.
SW-defined BTS
Flexi Multiradio 10 Base Station can be SW-configured according to requirements of a
given radio technology - GSM/EDGE, WCDMA/HSPA+, or LTE (TD/FDD). Additionally,
many SW-definable features can be activated by the software. For example:
sector activation (one, two, or three sectors active of a 3-sector RF Module)
RF power mode for active sector (8, 20, 40, 60, or 80 W)

g The full feature list for each RAT can be found in Feature List document.
Low acoustic noise
The 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 tothe BTS load and ambient temperature.
Easy commissioning
The 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 commissioning
wizard produces a BTS Commissioning Report.
Reliable operation
Simplicity and speed of maintenance improves operational reliability. Maintenance is
improved by module integration and automatic fault detection procedures. Specialattention 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-down
Intelligent 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
commissioning 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 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. As a 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
triggered by operator configurable timers per BTS. Different shutdown scenarios can beconfigured for the BTS by setting these timers.

7/26/2019 Nokia Flexi Multiradio 10 Base Station Product Description

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
gracefully, means the UEs in that cell will be forced to change to a different cell.
The timer values can be configured via NetActTM or with BTS Site Manager.
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 ACpower 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.

7.2 One BTS for all network applications
Flexi Multiradio 10 Base Station is optimized for high-capacity and wide-coverage
applications. 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 feederlosses.
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 line
Optimized 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
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 10 Base Station is on the RF Module front
panel. No additional units, connectors, or jumper cables are necessary between the FlexiMultiradio 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 voice
Flexi 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.
7.3 Feederless and Distributed Site concept
Standard 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.

8 Single RAN aspects
8.1 RF sharing
The RF sharing feature allows Flexi Multiradio BTS RF Module to operate in a
concurrent 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 frequency band. The RF Sharing concept simplifies the antenna system

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 Switching
QoS Aware Ethernet Switching allows multiple Ethernet interfaces in the BTS to be
connected 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 beshaped 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 trafficaggregation/daisy chain is to be implemented.
Synchronization Hub
Each 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
synchronization source. If PDH interfaces are available in the System Module, then they
can also be used for synchronization distribution to other devices.

If the BTS loses all sync sources, it switches to hold-over mode. Then, the BTS Oven
Controlled Crystal Oscillator (OCXO) keeps running with the last known control value,
and still provides the sync output.
System Module can use the following synchronization methods:
the TDM-based network interface
the packet network via:
Timing over Packet
Synchronous Ethernet
the 2.048 MHz signal
another Flexi BTS or a legacy BTS
the Global Positioning System (GPS)
the Global Navigation Satellite System (GLONASS)

9 Baseband capacity
Baseband capacity by SW license
Future-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 with 2x2 MIMO (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 evolution
Flexi 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 that triples 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).

10.2 Remote management
NSN provides an industry-unique NetActTM Network Management System (NMS)
platform that fully integrates with GSM, WCDMA, LTE, and transmission networks. One
graphical user interface covers the entire network - radio, core, and mobile backhaul.
Personnel trained to operate NetActTM can manage the network with small effort.
Operators who already have NetActTM can include LTE in the same NMS and thus fully
capitalize on their investment in the state-of-the-art NMS.
Flexi Multiradio 10 BTS, like the entire RAN, can be managed through NetActTM. The
advanced monitoring functions of NetActTM make it possible to minimize management
tasks that need to be carried out on the site. NetActTM incorporates a full range of
functions, from fault, performance, and configuration management to transmission,
trouble, and security management. The BTS site power and backup system can also be
monitored.
NSN also provides other higher level service management products, such as Service
Quality Manager, Serve atOnce Activation Manager, iSON Manager and Operations on
Demand.
For more information, see NetActTM documentation available in NSN Online Services
(NOLS), Product Information Center (PIC).
10.2.1 Remote User Event Log Management
Remote User Event Log Management (RUEM) is a feature that allows a network
management 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

Issue: 01G DN0971928 27
7/26/2019 Nokia Flexi Multiradio 10 Base Station Product Description

With RUEM, operations are logged on Flexi Baseband Controller (FCT) and sent to
NetActTMwithin 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)

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
10.2.1.1 RUEM concept - how does it work?
RUEM correlates every management operation with each user:
NWI3 and XOH management operations implement session concept
(username/password)
HTTP operations which are logged are operations that require username/password

Notification - Watermark
Operations 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 NetActTM(mediated by OMS in Flexi).
The RUEM upload mechanism
1. Triggered by NetActTM
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.
Exception:In case NetActTM 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.
10.3 Configuration management
Once 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.
10.4 Software updates
Flexi 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 NetAct TM 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 toput 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. A 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.
10.5 External alarms and controls
BTS 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 NetAct
TM
after they have been configured.
