1 Introduction

Nemo Analyze is a powerful and versatile, cutting-edge analysis tool for performing

benchmarking, troubleshooting and statistical reporting based on drive test data. The

system scales from a standalone tool to an enterprise-level client/server solution and

incorporates an innovative, low-maintenance database engine that has been designed and

optimized specifically for high-performance post-processing of drive test data. Nemo

Analyze helps you to streamline your processes by enabling you to automate the entire

data processing chain from a drive test to an open workbook with analysis results.

Nemo Analyze offers a comprehensive set of technology-specific Key Performance

Indicators for the latest wireless technologies and a wide range of data views that are

known to offer the best visualization of drive test data on the market - and yet it is highly

cost effective, easy to set up and use, and it scales to meet the needs of organizations of

any size.

Nemo Analyze offers support for all major wireless technologies, including GSM, WCDMA,

CDMA, EVDO, iDEN, TETRA, DVB-H, HSPA+, TD-SCDMA, WiMAX, and LTE. Nemo

Analyze supports the following network measurement tools: Nemo Outdoor, Nemo Invex,

Nemo Autonomous, Nemo Compact-i, Nemo Handy, TEMS™ Investigation, TEMS™

Pocket, R&S ROMES™, and EADS REMS TETRAPOL®. Measurement data in CSV

(Character-Separated Value) ASCII format is also supported.

2 What’s New in Nemo Analyze 6.10

This chapter lists new features and problem fixes in Nemo Analyze 6.10. Examples and

instructions for the most important new features are included.

2.1 Support for Nemo File Format 2.12

Nemo Analyze 6.10 is compatible with Nemo File Format 2.12 (Nemo Handy-A v1.0, Nemo Outdoor v6.10) and all older versions. Following metrics have been added:

• Support for LTE TDD measurements.

• Added support for new header information in the “Measurement settings view” of Nemo Analyze: license information from file header (#LICENSE, #LICENSEREGION), server hardware information. (#SERVERHW)

• Added support for call, data transfer, connection, SMS, and MMS timeout parameters (CAA, DAA, DREQ, MSGA)

• Added support for trace route time to live (TTL) and hop timeout parameters. (DREQ)

• Added support for radio state off indication. (LOCK)

• Added support for DNS query results. (DNSQUERY)

• Added support for LTE FDD 1900 band 25.

• Added support for scanner antenna imbalance power and frequency offset too large indications. (OFDMSCAN)

• Added support for RSRP, RSRQ, and CINR measurements per antenna port with scanner. (OFDMSCAN)

• Added support for band parameter for UMTS FDD RSSI measurement results. (CELLMEAS)

• Added support for LTE TDD frequency scanning. (FREQSCAN)

• Changed the unit of the LTE timing offset from microsecond to 32.552 nanoseconds that is the same as the Ts parameter in the LTE. (OFDMSCAN)

2.2 Support for TEMS Investigation 13.1 and TEMS Pocket 11.2

Nemo Analyze 6.10 adds support for TEMS Investigation 13.1 and TEMS Pocket 11.2 log

files. Newer files may work as well but have not been verified.

2.3 Support for R&S ROMES 4.64 Files and Other Improvements

Nemo Analyze 6.10 adds support for R&S ROMES log file of version 4.64. Newer files

may work as well but have not been verified.

Improvements and additions:

- GSM scanner BSIC mapping issue fixed

- RSRP and RSRQ mobile measurements issues fixed

- LTE PDSCH throughput and PUSCH throughput added

- Fixed missing channel numbers for LTE scanner results

- Added CINR results from LTE scanner

2.4 Live Maps: OpenStreetMap and Google Maps

Nemo Analyze 6.10 supports KML-based live maps, OpenStreetMap, and Google Maps.

Using live maps requires internet connection, the map tiles are retrieved as needed when

map is opened, zoomed, or panned. Live maps can be used the same way as regular

MapInfo maps. Data and base stations can be plotted on the map. When playing back

measurement data, the cursor is seen on the map and lines are drawn to the connected

base stations. Live maps can be found from the Maps tab of the Workspace. Data can be

dragged to the map same way as with MapInfo maps.

OpenStreetMap is included in the Nemo Analyze Professional feature package.

OpenStreetMap is a free map resource available globally. The maps are updated with the

same open source principle as e.g. Wikipedia. Currently the level of details in

OpenStreetMap is similar to Google Street Maps for the most part. Figure 1 illustrates

OpenStreetmap data overlay.

Figure 1. OpenStreetMap with route and base station overlay.

Google Maps is an optional feature. It incorporates the Street Map, Satellite view map,

hybrid map of satellite and Streets, and Physical map with terrain elevation illustrated.

Google Maps feature will be developed further in the coming releases to utilize more of the

capabilities of Google mapping interface. This includes elevation profile between the

mobile and base station, street view, and Google Earth integration. Figure 2 illustrates

Google Hybrid Map with data overlay.

2.5 Analytics Queries and Tables

Analytics feature is part of the Nemo Analyze Professional feature package.

Analytics consists of new summary tables in the Analyze database for voice/video call,

data, MMS, SMS, and handover events. The information in the Analytics tables is

essentially the same as in the corresponding standard database tables. The key difference

is that Analytics tables do not have the physical per measurement file federation as the

standard tables. This makes Analytics queries to execute significantly faster over large

(>100 log files) datasets when comparing to corresponding standard queries.


8

Analytics tables are populated with queries executed over the standard tables. Thus the

process has two steps: first the log file(s) are loaded into the Nemo Analyze database as

before. Then, AnalyzeAnalytics.exe, a process running on the background, will

automatically detect new files added to the database and run a set of queries over the files

and populate Analytics tables with the query results. Analytics can be enabled from the

View | Options | Database | Queries | Use Analytics to preprocess measurement data.

Analytics tables are visible for the end user via a new set of queries in the parameter tree,

under Analytics branch. The queries can be used to plot events on the map, calculate

statics, etc. in a similar manner as standard queries. Analytics queries can be also used in

custom workbooks and report templates.

Note that the file loaded to the database cannot be queried with Analytics queries

immediately after it appears in the database. There is an additional delay to process the

files, that is, to run the queries to populate Analytics tables. The extra delay is

approximately 4min per 1 hour of raw log file data.

When using Nemo Analyze Enterprise, Analytics starts automatically in the database

server.

Note that currently there is a limitation with Analytics queries in Nemo Analyze Standalone.

Analytics preprocessing may fail with long (>4hour) logfiles. The problem does not exist

with Nemo Analyze Enterprise.

2.6 (S)FTP Log File Autoload

Nemo Analyze 6.10 adds capability to load log files and autonomous rep files to the

database automatically over passive FTP or SFTP connection. Active FTP mode is not

supported. The feature is mainly targeted for Nemo Analyze Enterprise, but it can be

enabled also in Nemo Analyze Standalone.

Loading of the files over FTP is two-step process. First the files are retrieved from the FTP

server and saved to a local folder. Then the files are loaded from the local folder into the

database.

Following registry keys (Figure 4) have to be defined to enable the FTP autoload:

- db.autoload.directory (STRING). Local folder path where files received from FTP

are saved and from where AnalyzeSocketServer automatically loads them to

database

- db.autoload.extensions (STRING). Comma-separated list of file extensions to be

loaded. All Nemo logfile extensions are supported: nmf, nbl, rep,

gz,dt1,dt2,fs1,fs2,…

- db.autoload.ftp (STRING) where the format is same as with using url to logon to a

ftp server. For example sftp://username:[email protected]:22/files. Login

credentials can be empty as well as port and remote path in the end. E.g.

ftp://server.com

Optional registry key values:

- db.autoload.ftp.recursive (DWORD) 0 or 1 (default 0). Defines whether files under

subfolders on the FTP server are loaded or not

- db.autoload.ftp.interval (DWORD) 0 - INT_MAX (default 360) FTP file checing

interval in seconds.

Registry keys have to be set under

HKEY_LOCAL_MACHINE\SOFTWARE\Anite\Nemo Analyze\ServerSettings in 32bit


11

Windows and Nemo Analyze Enterprise server. In 64 bit Windows running Nemo

Analyze standalone the registry keys have to be set under

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Anite\Nemo

Analyze\ServerSettings
