Diagnostics and More
The Diagnostics screen may be useful when diagnosing network problems. The information presented here is
not needed for normal operation. The More button shows you some additional detail about your modem.
The following Diagnostics values are displayed:
• MCC Mobile Country Code (decimal value and, if available, decoded country name)
• MNC Mobile Network Code (decimal value and, if available, decoded network name)
• LAC Location Area Code (decimal and hexadecimal value)
• CID Cell Identifier (decimal and hexadecimal value)
• TA Timing Advance (decimal value and converted distance to base station in meters)
• BCCH Broadcast Control Channel (ARFCN or UARFCN value and converted frequency in MHz)
• BER Bit Error Rate
• RSSI Received Signal Strength Indication
• TCH Traffic Channel (ARFCN value and converted frequency in MHz)
• Batt Battery voltage as measured by the WWAN modem
• Temp WWAN modem Temperature
Note that TA, BER, and TCH are available only in GSM mode and only while there is an active connection (e.g.
a voice call). If the status in the main window shows No network found or Searching for network, then typically
only Batt and Temp are available. For the status Emergency calls only, MCC, MNC, LAC, CID, and BCCH may
be available. For the GSM 1800 MHz and GSM 1900 MHz bands it may not be possible to convert the ARFCN
for BCCH and TCH to a frequency because the channel numbers overlap. This can be overcome by enabling
only the GSM bands used by a particular network (i.e. either GSM 1800MHz or GSM 1900 MHz is disabled). If
the network uses frequency hopping during GSM voice calls, then hopping is displayed in the TCH field.
