2.2 CIRCUIT-SWITCHED DATA TESTING WITH NEMO

OUTDOOR
The CS data testing environment consists of three parts: a measurement unit (Nemo Outdoor),
an application server (Packet Data Tester, FTP server, HTTP server, POP3 server, or an SMTP
server), and a dial-up server. The dial-up server is used to establish a data connection between
the measurement unit and the application server.

The data measurement system has two modes: Send and Receive. In the Send mode, the
measurement unit sends data packets to the application server; in the Receive mode vice
versa. If you are using a FTP server, the measurement unit uploads (Send mode) or downloads
(Receive mode) test files to or from the FTP server. If you are using an HTTP server, the
measurement unit can only receive files.
The user can define the number of timeslots and the coding schemes, which in turn define the
desired transfer rate. During the measurement, the user will be able to monitor data throughputs
and error rates on different network layers, as well as certain parameters, such as, coding
scheme and number of timeslots.

4.1 NEMO OUTDOOR MEASUREMENT WINDOWS

The measurement windows in Nemo Outdoor can be monitored during the measurement
process. They are easy to open and close, and they can be adjusted and arranged to suit the
user’s working environment. Nemo Outdoor permits the user to display measurement results
(limited number) in any one of five methods. Results can be displayed in text, on a map, in line
graphs (single or multiple lines), in bar graphs (single or multiple), and in scatter graphs.

4.1.1 VIEW GROUPS

View Groups is a function that allows you to organize measurement windows into different tabs
for easier viewing. This is especially useful if you have several graphs and maps open at the
same time and you have to overlap them to fit them all in the Nemo Outdoor main window. Now
you can create view groups and organize the measurement windows into several groups. Each
view group appears at the bottom of the main window as a tab that you can view by clicking the
tab.

4.1.2 LINE GRAPHS

Measurement results from Nemo Outdoor can be displayed in a Line Graph in a variety of ways
to allow the user to accurately observe the measurement information. It is possible for the user
to display results on single and multiple line graphs. Multiple line graphs are useful in displaying
results, such as Ec/N0 for multiple pilots simultaneously. The user can also select the
parameters that are displayed in the numerical data table.

The zoom buttons can be used to view the results in more detail. The threshold function can be
used to set a threshold level. When the values exceed that level, the line will be drawn in a
different, user-defined, color. Furthermore, the scales are fully user-configurable.

4.1.5 MAPS

Nemo Outdoor supports MapInfo® raster and vector maps. It also supports MapX Geoset files
(.gst) which enable the user to open several layers on a map and then save them all in a .gst file
to be opened later on. All user-defined map settings, such as, the order of the different map
layers and the zoom factor are stored in the .gst file.
When Nemo Outdoor is used with a GPS receiver (positioning coordinates are collected) the
user can easily correlate events to positioning coordinates. Thus, it is easy to see the positions
at which key events have occurred.

The latest Nemo Outdoor version offers, as a new feature, parameter-based route coloring. This
means that you can observe the values of certain network parameters from the route coloring
on the map. You can define which color refers to which parameter value. This way it is easy to
spot the problem areas on a map.

6 WORKING WITH NEMO OUTDOOR

Nemo Outdoor can be used in different measurement modes for network monitoring and
optimization purposes, such as network troubleshooting and coverage analysis. The
measurement modes with WCDMA scanners are Frequency Scan mode and Pilot mode.

6.1 FREQUENCY SCAN MODE MEASUREMENT WITH A

SCANNER
Nemo Outdoor Frequency Scan mode is designed for basic frequency domain monitoring or
spectrum analysis. The scanning receiver can be used in variable bandwidth modes to check
the existence of wanted or unwanted radio signals in the defined frequency band. By using this
mode, all the user-selected carrier frequencies of the current wireless system and their field
strength values can be observed. In addition, if the Nemo Outdoor measurement system is
equipped with a GPS receiver, the position information is also stored by the system. Frequency
scanning results contain the field strength values for the carriers (and optionally location
coordinates provided by GPS). These results are stored into a scanning measurement file. The
data collected can be used, for example, for network planning and tuning and, furthermore, for
interference measurements.

6.2 PILOT MODE MEASUREMENT WITH A SCANNER

Nemo Outdoor Pilot mode is designed for scrambling code domain analysis. In this mode,
Nemo Outdoor is able to measure and decode the Pilot signal scrambling codes and their
signal-to-noise ratios (Ec/No values). In addition, the Primary and Secondary Synchronization
Channel Ec/No can be measured. Furthermore, Pilot Channel Time of Arrival and Absolute
Timing (referenced to GPS) can be observed. The complete RF signal power (RSSI) can be
measured as well as the signal code power (RSCP) for each individual scrambling code.

6.3 MEASUREMENTS WITH A MOBILE

A variety of WCDMA Layer 1 parameters can be measured with the supported WCDMA
mobiles; such as, parameters related to open loop power control and closed and outer loop
power control. Drawing line and bar graphs of active and neighbor cells is possible during
measurements for soft and softer handover testing. During a measurement, L3 messages (NAS
and RRC) are stored and they can be decoded to see the actual content of the L3 signaling.
Scripting is possible for voice calls and for CS and PS data. Also services available from mobile
can be used manually: the user can set up Nemo Outdoor for tracing and manually send MMS
and SMS from the phone or surf in the web and simultaneously record L1 and L3 data. This way
the user can test how the radio interface works when using different services that are possible
to use by the terminal.
