Info Element
Serving and Neighbors shows information such as Cell name, BSIC, ARFCN, RxLev, C1 and C2, about the current serving cell and its six strongest neighbors.
Radio Parameter: This window contains information about the radio environment.
Current Channel: This window shows information elements that are related to the channel, which for the time being is used. Here you can get information about CGI, BSIC, BCCH ARFCN etc.
17 © Nokia Siemens Networks Presentation / Author / Date Soc Classification level
Info Element
C/A: This window shows the level of interference from adjacent channels.
C/I is meant the carrier-to-interference ratio, that is the ratio between the useful part of the signal strength and the sum of the signal strengths of the undesired (interfering) signal components.
Line Chart: This window shows almost all information elements that are related to serving, neighbor and radio situation in chart format.

Map data preparation
There are many way to present GSM/DCS site geographically, but at least:1. Manual creation as a line object on mapinfo2. Automatic creation within TEMS Investigation 6.0 using theme of Cell file
Map data means: site data + other useful mapping data such as road, street,building, land contour, etc.
26 © Nokia Siemens Networks Presentation / Author / Date Soc Classification level
GeoSet Manager:- GeoSet Manager looks and works much like the Map Window.
- Changes made in the Map window cannot be saved.
- Changes made using the GeoSet Manager can be saved to the GeoSet (*.gst) file
associated with the map.
Creating geoset file can be done on the following step:1. Open a GeoSet Manager window
2. To create new one, cancel open window
3. Change GeoSet name on the available box
4. Activate layer control icon and load some necessary map data
5. Shown Label (site name) have to be put on the first column
6. Select site layer > check Automatic Labels on the properties group
7. If all data have been loaded, save the GeoSet using the name on point 3
8. When you have your own GeoSet file, you may open it on the map window

Customizing map presentation (1)
After a GeoSet file successfully loaded unto map window, we may customize itusing available theme setting. By default there will be some layers on the map:- Coverage Layer- RF Quality Layer- AMR Layer- Event Layer- Cell Layer- Pinpoint Layer
Available Theme:1. IE2. Event3. Cell Theme4. Pinpoint
29 © Nokia Siemens Networks Presentation / Author / Date Soc Classification level
Customizing map presentation (2)
• Click “Add Layer” button to add more layers• Click “Add Theme” on selected layer to add thematic data
- Choose fixed size and symbol- Change this setting using: Navigator > Info Element > GSM/CDMA > … Color/Range/Symbol

Connecting External Equipment
There are 3 steps :
1. Plugging In the equipment (MS, GPS, etc.)2. Enabling/Addition equipment3. Connecting/Disconnecting equipment
36 © Nokia Siemens Networks Presentation / Author / Date Soc Classification level
Plugging In Equipment
• Before plugging in any external equipment, please ensure to install required driver (i.e. GPS,
USB Hub)
• Attached dongle license to do this procedure
• Sony Ericsson GSM phones can alternatively connect by means of a dual port serial cable
(TEMS & DATA)
• Usually we need Serial-to-USB cable/connector to connect MS to laptop
• If number of available serial port on the computer is limited, try to use USB Hub.
• All equipment are in ‘powered on’ status
37 © Nokia Siemens Networks Presentation / Author / Date Soc Classification level
Enabling/Addition Equipment
• Manual Enabling
•Automatic Enabling

Sort by decreasing signal strength
Sort by increasing ARFCN
2. Frequency Scanning Mode (b)
51 © Nokia Siemens Networks Presentation / Author / Date Soc Classification level
3. Neighbor List Scanning Mode
Requires:MS1 as Master for serving cell in dedicated modeMS2 as Scanning for neighbor and others
Good candidate neighbor but not registered
52 © Nokia Siemens Networks Presentation / Author / Date Soc Classification level
4. C/A Scanning Mode
Serving ARFCN (hopped)
Adjacent ARFCN +/-1
Adjacent ARFCN +/-2
Suitable for Hopping Network rather than C/A which is delivered using “C/i-C/A” via tab Phone Property.
Avoid misleading in receiving data if it taken by Master Phone (old method).
Requires:MS1 as Master for serving cell in dedicated modeMS2 as Scanning for adjacent ARFCN
