Easy operation and high flexibility

up this procedure, users can create a project. A project contains all the settings of a workspace and reduces the

overall volume of the modules to be loaded when the software is started. The startup wizard makes it possible to fully automatically load and start a project, workspace or test file.

Easy-to-use interface that adapts to the user's level of knowledge

Featuring different user levels, R&S®ROMES4 can adapt to the user's level of knowledge. The different levels make it possible to adjust the displayed views and signals to what is most important for the individual user. Experienced and novice users alike finish their work faster.

Ready to use in no time thanks to workspaces and projects

Users can create a workspace in which to store all settings and loaded drivers. At the start of a new drive test, all they need to do is load this workspace and the test system is immediately ready to use. To further simplify and speed

Easy system configur ation with device manager and wizards

Multiple wizards help users configure a test mobile phone in order to perform application tests such as FTP or HTTP downloads. In just three quick steps, the user is ready to start testing. The device manager integrated in R&S®ROMES4 automatically finds and displays all connected test mobile phones and R&S®TSMx scanner options. With just three mouse clicks, the user can configure numerous application tests such as an FTP download. After successfully loading the drivers, R&S®ROMES4

automatically opens a selection of important windows that

display measured data. The test can then be started.

Fast setup due to automatic channel detection

The R&S®ROMES4ACD automatic channel detection feature enables the R&S®TSMW and R&S®TSME drive test scanners to automatically detect active channels in a specified band. LTE, UMTS and CDMA2000®/1xEV-DO networks are supported. The feature can be optionally enhanced by a spectrum scan that significantly speeds up the detection process. This feature eliminates the need to set up channel lists prior to a measurement campaign. The measurement system dynamically identifies new channels and adds them to the workspace during the drive. This is particularly relevant in networks deployed in a shared spectrum with other cellular standards, where channel

frequency and channel bandwidth frequently change.

Support of numer ous map data formats

In addition to the MapInfo map data format, R&S®ROMES4 also supports OpenStreetMap (OSM). Once downloaded, maps are also available offline. This is particularly important when testing data calls to ensure that measurement results are not affected by map downloads. Measurement results can be exported in ASCII format or converted to a

Google Earth format. With the Google Earth format, a drive test can be displayed on a map with no additional effort.

Powerful analysis tools

When multiple, long drive tests need to be automatically evaluated for network errors and the cause for these errors determined, the R&S®ROMES4NPA network problem analyzer is the ideal tool. The base module for displaying

ETSI key performance indicators (KPI) and providing an overview of the data in the measurement files is included with R&S®ROMES4. Optional modules for dedicated error analysis of voice or data calls automatically evaluate and display the error causes. Other modules enable analysis of coverage test data and neighborhood relationships as well as delta and comparative analysis. LTE MIMO measurements can also be analyzed and evaluated (see page 20 for more details).

OpenStreetMap (OSM)

OpenStreetMap (OSM) is a user-editable world map that is available at the following Internet address: http://www.openstreetmap.org/

OSM is a wiki project in which users can participate by uploading and editing geographical information such as GPS tracking data or the course of a road or river. This world map is growing daily.

Automatic handover and neighborhood analysis

A utomatic detection of missing neighboring cells during drive testing

Automatic neighborhood analysis is based on a base

station list and the base stations' broadcast signals that are decoded by the R&S®TSMx scanners. These system information blocks (UMTS and LTE) or system information types (GSM) include information that is normally used by test mobile phones to identify and monitor relevant

neighboring cells. The report containing the measured

values of the neighbor channels is forwarded to the base station. If necessary, the base station can use this

response to initiate a handover.

Improvement of network coverage

Unlike test mobile phones, the R&S®TSMx scanners see all signals. These signals can be allocated to the relevant neighboring cells. R&S®ROMES4 is thus able to automatically compare the measured data from the scanners and the test mobile phones against a base station list to

identify any missing neighboring cells. These missing cells may originate during the setup of a network and, in the worst case, can terminate a call.

The SIB analyzer integrated in R&S®ROMES4 compares the neighboring cells measured by the scanner against those in the base station list. Neighboring cells that were detected but do not appear in the list are marked in yellow, indicating a missing neighborhood. This automatic neighborhood analysis works for UMTS; a comparable functionality exists for GSM. Both work in realtime. For TETRA and

LTE, this functionality is included in the R&S®ROMES4NPA network problem analyzer (see page 18).

Creation of different application jobs

Mobile data calls are the standard today. It is therefore essential that data services be optimized with respect to quality and data throughput. This requires tools that can be used to configure, display and evaluate the different data measurements and packet-switched services.

R&S®ROMES4 offers two different test solutions that are based on differing test concepts.

Data throughput measurement on a PC

The R&S®ROMES4DQA data quality analyzer makes it possible to perform data tests using a commercially available mobile device (mobile phone, data stick), where the mobile device either acts as a modem or is connected via

NDIS. The test is evaluated on a PC. This ensures that the latest devices are always used for testing and enables fast response to new technologies such as LTE carrier aggregation. DQA jobs can be run in parallel so that users need just a few mouse clicks to generate the high data loads

required for LTE CA and start testing.

By appropriately linking parallel and sequential jobs, the behavior of Internet users can be simulated.

R&S®ROMES4DQA supports the following applications, which can be combined in an individual job list: SMS, e-mail (POP3 and IMAP), ping, UDP, FTP, HTTP and video streaming.

Innovative on-device testing

When used together with a suitable SwissQual QualiPoc

Android phone, the R&S®ROMES4SMP smartphone

option sends all of the messages and analyses directly to the smartphone. This ensures an almost exact simulation of user behavior. R&S®ROMES4 GUI makes configuration easy and convenient. Up to six wired devices can be controlled in parallel. Depending on the device, voice quality analyses and VoLTE measurements can be performed in addition to data tests (incl. carrier aggregation).

R&S®ROMES4 includes the following jobs, which also can be assigned to a job list: e-mail, ping, FTP, HTTP,

HTTP capacity test, Call2AnyNumber, double-ended voice quality and MOC DL voice quality.

The SwissQual QualiPoc Android phone can also be used as a standalone device, for instance for indoor measurements. This increases the flexibility and saves costs, since only one device is needed.

Output of KPIs and the most important network parameters in a report

Display of mobile phone activities in layer 3

The basic functionality of R&S®ROMES4 in combination with the drivers for test mobile phones provides a large amount of information from layers 1 and 3. Users can see the radio conditions (GSM or WCDMA, channel, voice

codec, etc.) for phone calls at a glance.

If measurements are also taken by a scanner, the scanner's measured data is displayed in the same window, allowing a direct comparison.

Layer 3 View displays all the messages, sorted by uplink and downlink. Each message is decoded and can be opened if necessary.

Fast analysis of interrupted connections

In addition to protocol messages, interrupted/blocked and successful connections are also displayed. When jumping to a trouble spot, all views will show measurements taken at this point in time. This makes it considerably easier to find the cause of a problem.

In addition, a filter function in Layer 3 View enables users to evaluate only specific messages.

User-friendly configuration for checking voice quality

Mobile networks must meet increasingly high demands for quality. For testing voice quality, R&S®ROMES4 offers an innovative, full-featured, end-to-end solution that

exactly simulates user behavior.

The test mobile phone is connected to the R&S®ROMES4 via USB and configured using a job list. A POLQA algorithm (ITU-T P.863) evaluates the voice quality directly on the phone. The results are displayed live in R&S®ROMES4.

The greater the difference between the transmitted voice signal and the reference signal, the poorer the voice

quality. This is indicated by the usual mean opinion score

(MOS) and can lie between 1 (poor) and 5 (very good).

Complete end-to-end measur ement from the user perspective

The measurements can be performed using a fixed- network station, usually a voice-quality server, or another mobile phone. The mobile phone reflects the quality as experienced by a mobile user and also permits HD voice measurements. In contrast, a fixed-network station serves as a reference, enabling the cause of a poor MOS to be found more quickly.

Based on POLQA standard

The R&S®ROMES4SMP option and a suitable QualiPoc

Android QA can be used to measure calls for the downlink and uplink. For the downlink, the server replays a reference voice signal, and the QualiPoc Android QA

connected to R&S®ROMES4 evaluates this received signal.

For the uplink, the R&S®ROMES4 test system replays a voice signal and the server uses a POLQA algorithm to evaluate it.

Following a drive test, the measured data can be merged so that the uplink and downlink measurements are available in one log file. The merge process can be skipped if two phones connected to R&S®ROMES4 call each other.

R&S®ROMES4 in combination with a

Rohde & Schwarz LTE scanner and an LTE eMBMS test mobile

LTE broadcast, using the evolved multimedia broadcast multicast service (eMBMS) feature of LTE, allows operators to more efficiently provide services to a large number of subscribers. Instead of transmitting video and data content separately to individual users, broadcast saves network resources, making it attractive for areas such as event venues where a multitude of subscribers request the same type of content.

Enabling broadcast in an LTE network poses challenges for the network operator. It is necessary to ensure continued high quality unicast services and simultaneously provide high-performance broadcast services. The broadcast network consists of a virtual single frequency network

(SFN) inside the LTE network, where a set of eNodeBs that are part of the same broadcast area transmit the same downlink signal at the same time. This requires accurate eNodeB synchronization, which is typically not the case in LTE-FDD networks. In addition, intersymbol inter ference becomes important in the SFN. The eMBMS

feature already makes use of the extended cyclic prefix, but when planning and commissioning the broadcast network it is crucial to validate that the network footprint at the given operating frequency does not lead to intersymbol interference.

R&S®ROMES4 in combination with an LTE scanner, such as R&S®TSMW, R&S®TSME or R&S®TSMA and an eMBMS capable test mobile is the ideal solution for optimizing such a network.

Typical measurement setup with R&S®ROMES4, R&S®TSMA and eMBMS smartphone.

Netw ork planning

With the scanner, the LTE network can be baselined in the planning phase, and the network synchronization can be checked against GPS. This allows the network planner to predict potential areas of intersymbol interference and

allows planning of the MBSFN area IDs, similar to PCI planning in an LTE unicast network.

Check of network configuration

The scanner decodes the SIB2 and SIB13 broadcast messages that include information on the eMBMS configuration in the network, such as MBSFN subframe configuration from SIB2, and MCCH configuration per MBSFN area from SIB13. So in the field, the engineer can check that the network is configured correctly.

Network rollout

During the network rollout and tuning of the broadcast network, the scanner can measure the power (RSRP) and quality (SINR) of each MBSFN area. The engineer can then check the validity of the network planning by comparing it to the results from the field.

Detection of intersymbol interference

The scanner can also be used to detect intersymbol interference. Due to the impulse response measurement per PCI, it can also detect which eNodeB is causing this interference, allowing the engineer to take corrective measures.

Validation of network performance

While the scanner allows optimization of the RF environment, it is also crucial to validate the network performance with a test mobile. R&S®ROMES4 supports eMBMS test mobiles with a Qualcomm chipset, so the engineer can test the connection to the eMBMS network, view layer 3 and flute messages, capture the IP trace, and therefore analyze problems in the broadcast network. While testing eMBMS, it is important to continue testing the unicast services (data and VoLTE) to ensure that service quality stays at a high level when introducing the eMBMS feature.

Variety of applications

The LTE downlink allocation analysis result, for example, can explain the limited throughput of a test mobile phone if the scanner shows that the cell load is already high and therefore not enough resources are available for the test mobile phone.

In a benchmarking environment, this feature provides deep insight into networks, allowing comparison of traffic and available capacity between different operators.

Allocation analysis of the strongest eNodeB in the downlink

In combination with the R&S®TSMW or R&S®TSME

scanner, R&S®ROMES4 offers a unique feature that

allows analysis of the DL allocations of the strongest

eNodeB during measurement. The following information is included:

❙Number of RNTIs (UEs) that have been scheduled data by the eNodeB

❙Modulation and coding scheme (MCS) and throughput for each detected UE

❙Cell allocation

Another application is as a network probe to measure the cell load in a stationary situation, for example when a base station site owner wants to know the importance of a certain base station before renewing the lease with the network operator.

Broadband spectrum measurement

In combination with an R&S®TSMU, R&S®TSML,

R&S®TSMQ or R&S®TSMW scanner, R&S®ROMES4 can be used to perform a spectrum scan. The user can select up to 32 frequency ranges from 80 MHz to 3 GHz (30 MHz to

6 GHz). The frequency range is not limited. R&S®ROMES4 offers different display options, e.g. envelope spectrum measurement, RMS, peak or a predefined channel mask.

In this case, the power per channel is displayed.

The spectrum function is based on FFT analysis. Various

FFT sizes allow users to set measurement bandwidths down to min. 140 Hz. The smaller the measurement bandwidth, the greater the measurement accuracy. This permits a very fast spectrum measurement without the usual sweep time of a normal spectrum analyzer. Fast measurements are especially important during drive tests in order to obtain a sufficiently high density of results during the drive.

A special threshold value is provided for monitoring the spectrum. Spectra that do not show any test points above this threshold value are not displayed. Any data that is not of interest is not recorded.

Frequency markers and the entire spectrum can be

exported to ASCII format.

Marker functions make it easy to precisely measure

dedicated frequencies and detect changes. A marker can also be defined as a reference and compared against the maximum value.

Cr eation of a base station list during a drive test

The R&S®TSMW and R&S®TSME scanners enable users to estimate the geographic position of base stations. This can even be done for GSM, WCDMA, CDMA2000® 1xEV-DO and LTE base stations in parallel.

Requires only scanners and GPS

For the calculation algorithm, all that is needed are the measurement parameters from a highly accurate GPS receiver with output of the PPS time reference signal

( pre-installed in the R&S®TSMW and R&S®TSME) and from the 2G/3G/4G scanner.

The R&S®ROMES4 software and the R&S®ROMES4LOC driver allow the scanners not only to detect the main levels of the BTS (2G: RxLev, 3G: RSCP, 4G: RSRP) but also to demodulate the broadcast channels (BCH). Important time information as well as details of the transmitting BTS are thus obtained.

The maximum likelihood method is used to calculate the geographic position of the individual BTS from the measured data provided by the GPS receiver, BCH time information and level changes during the drive test.

Following the drive test, the calculation results are

exported to a base station list and the located base

stations are displayed on an underlying street map.

Selecting the BTS opens another window in which the characteristic data of the BTS is displayed.

The calculated position of a BTS lies within an error ellipse

(approx. 200 m) that is also exported. Base stations can be filtered based on the accuracy of location estimation.

Stationary or mo ving measurements indoors – without GPS signal

High-quality wireless communications coverage inside buildings, e.g. at airports, shopping malls and exhibition halls, is gaining in significance, especially with respect to data traffic. Since GPS reception indoors is limited or

nonexistent, R&S®ROMES4 offers an alternative to conventional navigation display (GPS data on a map).

Combined indoor/outdoor measurements

The R&S®ROMES4IND indoor driver option provides a separate means of navigation that makes it possible to display positions on a floor plan. Measurements can be taken at specific points (hot spots, e.g. in conference rooms) or along a specific path (continuous, e.g. in a corridor). Combined DUTs (comprising buildings and outdoor areas such as company premises) can be optimally measured and georeferenced. The software also displays a smooth transition to areas covered by GPS. Measurements of multifloor buildings are easily handled by displaying the various floors as multiple layers on the map. The wide support of georeferenced and non-georeferenced map formats

(tab, jpg, tif, bmp, png) and included import functionalities for iBwave ibwc and AutoCAD DXF files simplifies and speeds up daily work. The layer that corresponds to the floor where the user is located is visible on the map. The complete integration of the indoor functionality into the

R&S®ROMES4 map display allows intuitive operation.

Automatic measurement and identification of interferers from own GSM mobile network

R&S®ROMES4 allows GSM interference to be determined automatically and clearly from the own GSM network during the drive test. The actual interferers can be displayed on the underlying street map in Route Track View.

This makes it considerably easier to use the software and perform tests, reducing costs dramatically in comparison with conventional methods.

❙Classification of the actual interferers on the basis of the individual interference situation and pinpointing of the interferers on the street map (interfering base station with channel indication: BCCH, TCH, adjacent channel)

GSM interference analysis with automatic interferer identification: display on the map

The map shows the position of the interference (cross line), the cell currently providing coverage (S) and the four actually interfering cells

(I1, I2, I3 and I4). The markings N1 to N6 show the current neighboring cells. The color of the route indicates the received signal strength of the GSM mobile phone.

16


To optimize interference analysis, more than just selectable trigger thresholds (e.g. RxLevFull, RxLevSub, RxQualFull,

RxQualSub, FER) are used. Some of the test mobile phones supported by R&S®ROMES4 also provide a C/I

value for the traffic channels being used (TCH). Because the SIM connection only allows the test mobile phone to see the data from the allocated mobile network, and because it is not very RF-sensitive, the use of high-grade scanners is absolutely essential.

Detection of adjacent-channel and co-channel interferers

The combination of scanner and test mobile phone can even be used to measure the power in the time slots being used (TCH, TS Time Slot), making it possible to identify not only interfering BCCH channels but also TCH interferers.

Ev aluation of BCCH and TCH channels allows full-featured analysis

The R&S®TSMW, R&S®TSME and R&S®TSML-CW scanners are able to instantly detect all selected RF channels

(BCCH) and demodulate the BCH information. As a result, all the data from the BTS transmitting the signals is available. This is especially relevant when performing measurements in the vicinity of national borders (faulty frequency allocation, roaming, etc.).

❙R&S®ROMES4NPA (included in R&S®ROMES4)

❙R&S®ROMES4N11








A utomatic detection, analysis and documentation of trouble spots

The sheer volume of recorded data makes individual and manual analysis impossible. The data is therefore

analyzed by the R&S®ROMES4NPA network problem

analyzer, which outputs a list of all detected trouble spots and displays them on a map using Google

Maps, OpenStreetMap (OSM) or user-defined maps.

R&S®ROMES4NPA also provides information about the cause of the problem.

Sophisticated algorithms for supporting users

The easy-to-use interface guides the user through the process, from reading in the measured data (from one or more drive tests) and selecting the analysis criteria to

retrieving the automatically generated list of trouble spots.

Right-clicking a problem automatically opens

R&S®ROMES4 and positions the replay of the measurement file just ahead of the trouble spot in question so that the user can perform a detailed check if required. The

result is displayed in HTML in a clear report that is ready for printing. Export to Excel allows easy data processing.

The measurement data is analyzed according to specific criteria that depend on the modules selected. In all modules, the analysis criteria can be adapted to user-specific limit values and settings.

The R&S®ROMES4NPA base package includes the following modules:

❙NQA (network quality analyzer) for voice calls, base module including KPIs

❙DQA (data quality analyzer) for PS data connections, base module including KPIs

R&S®ROMES4N15

Coverage module with display of coverage data on a raster map

Coverage data (GSM, WCDMA, CDMA2000® 1xEV-DO,

TETRA or LTE) measured with Rohde & Schwarz scanners is rasterized and displayed on the map using Google Maps or OpenStreetMap (OSM). This makes it easy to generate coverage plots. Optimizations can be checked using a

before-and-after comparison.

R&S®ROMES4N17

Neighborhood analysis module for automatic classification of neighborhood relationships into one of the following categories

❙(Potentially) missing neighbor: a cell with high signal strength and good quality (both thresholds can be set) has been measured but is not contained in the currently defined neighbors

❙Unused neighbor: a cell is configured as neighbor but has not been detected during measurement

❙Approved neighbor: a cell has been classified as a

(potentially) missing neighbor and is contained in the neighbor list. Analysis of intra-RAT handover in the network problem analyzer (NPA) is available for

GSM, UMTS, LTE and TETRA. Inter-RAT handovers are currently limited to GSM and UMTS, but will soon be available for LTE as well.

BTS evaluation – summary of key BTS parameters as acceptance criterion

To ensure a consistently high degree of network quality, continuous improvements must be made to the mobile network, such as updating the parameters for a mobile base station, replacing hardware or adding new base

stations. Each time such improvements are made, the

effects on neighboring base stations as well as the mobile network as a whole must be documented and evaluated.

The BTS evaluation on the NPA performs these tasks

reliably, fast and cost-effectively.

R&S®ROMES4N30

Delta and comparative analysis of R&S®ROMES4 measurement data

This add-on module enables a quick comparison of measurement data, for example for visualizing the effects of an implemented network optimization. Measurement data from different cells, UEs or operators can also be compared for benchmarking.

R&S®ROMES4N20

Data module for EDGE, HSPA+ and LTE data links including problem spot detection

This module offers specific analysis of high-speed data links for achievable data rates and analysis of potential problems as well as an IP data analyzer for analyzing

IP-based data traffic and associated problems. When IPbased data services are used, e.g. web browsing or e-mail, this module analyzes the results and shows problem spots and their cause. A comprehensive collection of different analyses is available especially for LTE.

R&S®ROMES4N31

LTE MIMO and downlink allocation analyzer

LTE MIMO analysis is performed based on the condition number (CN) and rank indicator (RI) values measured by the scanner. If mobile device data is available for the

analysis, the efficiency per Hz or resource block is also

included in the analysis. Any inconsistencies in the condition number, efficiency per resource block or condition number matrix are displayed as problem spots on the map and designated in tables.

The result analysis from the downlink allocation analyzer lists the cell throughput per TTI and operator as well as maximum and average cell throughput in a table and graphically.

Comprehensive set of reporting functions

If multiple drive tests are selected, the user can draw

statistical conclusions about quality in the measured areas.

A comparison between various network operators in the same area is also possible (benchmarking).

Automated analysis with R&S®ROMES4NPA considerably saves time and reduces costs. Optimizing the results no longer requires time-consuming manual checks and analysis of data that may not even contain any problems.

A further way to evaluate analysis results in greater detail is to use sophisticated filter algorithms (e.g. for examining only one operator/one cell or only specific times or days of the week). The dynamic context filter algorithm makes this even easier and faster. For analyzing dedicated geographical areas, polygon filters can easily be drawn on the map.

The result analysis and statistics are automatically tuned to the active filters.

R&S®ROMES4NPA uses sophisticated algorithms to help users find problem causes. More in-depth analyses can be performed at any time. A large amount of measured data can be automatically and quickly processed; reports – for management and for general documentation – are

generated without requiring user interaction.

❙R&S®ROMES4

❙R&S®ROMES4DQA

❙R&S®ROMES4LTS (Samsung LTE driver)

R&S®ROMES4LTQ (Qualcomm LTE driver)


R&S®ROMES4T1E (scanner driver)

❙R&S®TSMW scanner or

R&S®TSME scanner

In addition to measuring data throughput, measurement data of layer 1 and layer 3 messages is recorded.

Qualcomm or Samsung chipset-based LTE mobile phones or data sticks display detailed information about individual data packages so that often a quick glance is enough to detect possible causes of error.

V oLTE measurements

LTE is also increasingly used for voice transmission. IPbased telephony via VoLTE places higher demands on network quality because users have less tolerance for poor voice call quality, such as dropped calls, than they do for data calls. In addition to the normal chipset trace data,

R&S®ROMES4 also supports output of the SIP signaling used for VoLTE. This makes it possible to collect voice KPIs for VoLTE and identify the cause of errors.

Coverage analysis with Rohde & Schwarz scanners

This essential analysis determines whether an LTE signal of sufficient strength is available at the test site.

R&S®ROMES4 and TopN View can be used to clearly display the results and plot them on a map. For signal strength, the R&S®TSMW and R&S®TSME scanners deliver the RSRP value or the power of the P-SYNC/S-SYNC signals. In addition to signal strength, the reference signal received quality (RSRQ) and the signal to interference-plus-noise ratio (RS-SINR) for each cell as well as the SINR for the SYNC signals are displayed. If one of these values is too low, this indicates interference, intermodulation or other types of disturbance. In this case, the R&S®TSMW/R&S®TSME and R&S®ROMES4 offer a more detailed cause analysis.

Data throughput measurements with the LTE test mobile phone

R&S®ROMES4 collects scanner data and measurement data from the Qualcomm or Samsung LTE test mobile phone. One of the most important parameters is data throughput. If it is too low, the cause may be a low-order modulation format such as QPSK or the use of SISO rather than MIMO. A comparison with the scanner data permits further conclusions about possible causes. Interference, multipath propagation, handover failures or even weak network coverage might be the cause of error.

Interference analysis

LTE is a single frequency network (SFN) that is identified by a reuse factor of 1. This means that neighboring cells use the same frequency ranges. Interference is therefore especially frequent and must be analyzed to avoid capacity losses to the greatest possible extent. This is a special challenge for T & M equipment because the interference can also affect the T & M equipment itself. The R&S®TSMW was developed specially for this task and features an impressive C/I value of –20 dB. Even signals that are 20 dB weaker than the strongest noise can be measured, making it possible to identify interferers and reduce interference.

The R&S®TSMW can also distinguish between signals that have the same physical cell ID but come from different eNodeBs. It makes no difference whether the measurement is performed in the FDD mode or in the TDD mode.

TopN View shows eNodeBs signals sorted by strength.

Cyclic prefix analysis

A special feature of the Rohde & Schwarz LTE drive test solution based on the R&S®TSMW and R&S®TSME is the channel impulse response (CIR) measurement. This

involves a channel measurement performed over a period of time. R&S®ROMES4 displays the multipath propagation of the signals – also referred to as echos – in a power vs. time diagram. As an OFDM standard, LTE has a defined frame length and a fixed guard interval, also

referred to as a cyclic prefix. This value is necessary in

order to wait for echos in the receiver. A cyclic prefix that is too short or an echo that is too long can cause problems in the subsequent frames. This is referred to as intersymbol interference (ISI). The effect manifests itself in a low SINR. R&S®ROMES4 can measure the length of the cyclic prefix and match it against the multipath propagation. This enables the user to draw a conclusion about how often multipath propagation disturbs the subsequent

symbol, whether a longer cyclic prefix would be better and whether the network needs to be optimized, e.g. by

adding eNodeBs.

Demodulation of eNodeB broadcast information

The R&S®TSMW or R&S®TSME can scan LTE signals and also demodulate broadcast signals. The broadcast information from previously detected eNodeBs is demodulated (MIB and SIBs) to learn more about the base station.

Based on this information, the user knows the country, the network and the cell from which the received signal originates. Neighborhood relationships (intra-RAT and

inter-RAT) and handover thresholds are also visible. All these values make it easier to classify the signals and

detect problem spots.

Subband measurements

The LTE wireless communications standard permits channel bandwidths of 1.4 MHz to 20 GHz. While the synchronization and broadcast information is contained within a bandwidth of approximately 1 MHz in the center of the

LTE carrier, useful data is transmitted over the entire bandwidth. Narrowband interference outside the center of the carrier can be detected through subband measurements performed on the LTE scanner. The SINR of the reference signals is determined for every resource block (12 subcarriers corresponding to 180 kHz). R&S®ROMES4 graphically displays these values in a waterfall diagram. Interferers are visible as vertical lines in the diagram.

MIMO measurements

MIMO plays an essential role in achieving high data rates in LTE networks. Ideally, using MIMO will double the data rate. Whether this is possible in each specific case depends on the characteristics of the radio channel. The characteristics can be measured using the R&S®TSMW together with the R&S®TSMW-K30 MIMO option. The scanner receives the eNodeB reference signals from both transmit antennas at its two independent frontends. These signals are then used to determine the transmission matrix for the radio channel and the condition number. The condition number describes how successfully MIMO can be used. If the condition number is low, the radio channel is suited for MIMO. The MIMO and SINR measurements can be used to explain the data rates achieved with the test mobile phone.

CIR V iew shows the channel impulse response (CIR) and all parts of the multipath propagation (echos) together with a cell's cyclic prefix.

❙R&S®TSMQ scanner or

Upgrading existing UMTS networks and rolling out

HSPA(+) networks place highly complex demands on

network optimization. In order to be successful on the market, high data rates must be reliably available. Low data throughput can have a variety of reasons; each must be identified and eliminated.

R&S®ROMES4 provides more than 15 HSPA(+) specific views that show all the important parameters in a fast, straightforward manner, quickly providing performance information.

By downloading and uploading large files from and to

specific servers, R&S®ROMES4 makes it possible to

perform end-to-end tests that take into account the overall infrastructure (data card – air interface – RAN – core

network). Depending on the test mobile phone, MIMO and

64QAM messages are supported.

This can all be done either for an individual network

operator or for several network operators in parallel. To optimize an HSPA(+) network, the user first observes the data throughput with the R&S®ROMES4DQA option. If the data throughput is too low for network expansion, the user switches to a CQI measurement. If the average data throughput is very low, the reason may be insufficient coverage or pilot pollution. In the case of pilot pollution, the number of signals of equal strength at this location should be reduced. A scanner is especially advantageous for such measurements because it can reliably detect all signals on the air interface. A low CQI is related to small block size and low-order modulation. By increasing the two, the throughput rates of a network can be optimized.
