Parameters:
This command is for WCDMA only.
Query:
Response:
Purpose:
Return the total energy per chip per power density (Ec/Io) value of the active set’s three
<value> (Ec/Io of cell in the active set):
Note: The command +USET also displays Tot Ec/Io as one of its outputs.
Execution:
Query:
Response:
Purpose:
Enable/disable checking of average E-TFCI values during HSUPA call, or return the value.
The average value is based on 64 sets of log values extracted from the E-DPCCH packet:
An HSUPA call must be in progress to obtain the E-TFCI.
<status> (E-TFCI reporting status):
<etfci> (Average E-TFCI value over sampling period):

Purpose:
or
Valid range: -31.5 dB to 0 dB
• Every 200 ms (for 10 ms TTI)—Each set includes 20 samples. A total of 1280
• Every 80 ms (for 2 ms TTI)—Each set includes 40 samples. A total of 2560 samples
0 = Disabled
1 = Enabled
Valid range: 0–127
samples are taken (200 ms/set, 20 samples per set, 64 sets over 12.8 seconds).
are taken (80 ms/set, 40 samples per set, 64 sets over 5.12 second period).
AT+ECIO?
+ECIO:
Ec/Io: <value1> dB [<value2> dB [<value3> dB]]
Return the signed dB values of the three strongest cells in the active set.
The values are listed from strongest to weakest, based on RSCP, and
separated by tabs. If there are less than three cells, only those values
appear. For example:
AT+ETFCI=<status>
+ETFCI:
ENABLED!
OK
+ETFCI:
DISABLED!
OK
Enable or disable the ability to check the average E-TFCI value.
AT+ETFCI?
+ETFCI:
Status: <status>
total samples 1280, average etfci <etfci>
OK
Indicate if E-TFCI checking is enabled, and report the total number of
samples and average E-TFCI value.
+ECIO:
Ec/Io: -3.5 dB -14.0 dB -24.5 dB

+ECIO:
Ec/Io: -7.5 dB
