Cell Module TAQ Reconnection X X 2.84
Tracking Area Code; only available when cell verbose
mode is enabled.
Cell Module ID Reconnection X X 2.84
Cell Identifier; only available when cell verbose mode is
enabled.
Cell Module EARFCN Reconnection X X 2.84
E-UTRA Assigned Radio Channel; only available when
cell verbose mode is enabled.
Cell Module PWR Reconnection X X 2.84
Received signal strength in dBm; for serving cell in UMTS
network this is not available during a call, and is
displayed as 0; only available when cell verbose mode is
enabled.
Cell Module DRX Reconnection X X 2.84
Discontinuous reception cycle length; only available
when cell verbose mode is enabled.
Cell Module PRE_BER=7 On Reset X X 2.84
Bit error rate before registration is confirmed. Data is
brought back on next successful call even if registration
fails which can be used in troubleshooting connection
failures. See BER for details.
Cell Module PRE_CCSQ=-51 On Reset X X 2.84
Reported RSSI value before AT+CGREG command is sent
out. Value may not be from the carrier you want to
register on. (data is brought back even if registration
failed)
0 - (-113) dBm or less
1 - (-111) dBm
2…30 - (-109) dBm..(-53)dBm / 2 dBm per step
31 - (-51)dBm or greater
99 - not known or not detectable
