3. By clicking the Select Channels button, you can access the Select Channels dialog.

Figure 167 LTE Frequency Scanning: Select Channels

4. Select one band from the list or all of them. You can also select one band at a time and add the

bands you want to scan. If all bands are selected, you have the possibility to select Remove All
| ... items from every band. Alternatively, if only one band is selected you can remove only
items from the current band through Remove All | ...items from current band. The Available
view provides a list of channels that are available for scanning. To add channels to the Selected
list, click on a number in the Available list and then click the Add button or simply double-click a
channel to add it to the Selected list. To select all available channels for scanning, click the Add All
button. An alternative method to select channels is to type the channel numbers in the field at the

bottom of the dialog and to click Add. To remove channels from the Selected list, click on the
channel you want to remove and then click the Remove button or double-click the channel. To
remove all channels, click the Remove All button. You can select several channels simultaneously
by holding down the SHIFT key and clicking on the channels you want to add or remove.

5. After making the appropriate settings, click OK and OK again and go to online mode to start the
scanning.

6. A green light on the scanner Device Info window should start blinking. This means that the device is

working properly and scanning using the default settings.

7. Click the Start Recording button to start recording the results in an output file.

14.2 Frequency Scanning - PCT GSM Scanner

1. After the scanner is connected and activated in Nemo Outdoor, open the Measurement
Properties dialog by selecting Measurement | <device> | General Properties.

2. By clicking the Advanced button, you will access the Advanced Properties dialog. Here you
can enable and disable the integrated GPS receiver. This means you will not need an external

GPS receiver in order to collect position data.

3. Go to the Frequency scanning page

Channel style refers to the style of the channel.

Selecting the BSIC decoding option displays BSIC value in a measurement window.

BSIC threshold defines the minimum BSIC level that the scanner reports.

Select the BCCH C/I check box to activate C/I measurements for the BCCH channel. This option
is available with PCTEL GSM scanners only.

By clicking the Select Channels button, you can access the Select Channels dialog.

4. By clicking the Select Channels button, you can access the Select Channels dialog.

27.3 DOS FTP

DOS-FTP – can be used as resort when Winds and Iperf are not available
 Open up a command prompt by click on start->run->type cmd and hit enter
 Log into the FTP server

o ftp 135.245.4.38
o Inter user name (e.g admin)
o Inter password (e.g admin1)
o Change directory to where the files would be downloaded from or uploaded to
o Set to binary by typing “bin” and press enter key
o Set to hask key by typing “ha” and press enter key
