Modem Status, Customization, and Reset Commands

+ECIO?

Supporting modems:

• All

Returns total Energy per chip per power density value

(WCDMA only)

This command returns the total energy per chip per power density (Ec/Io)

value of the active set’s three strongest cells.

Usage:

• AT+ECIO? returns 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:

+ECIO:

Ec/Io: -3.5 dB -14.0 dB -24.5 dB

---or---



+ECIO:

Ec/Io: -7.5 dB

• Valid range = -31.5 dB to 0 dB

• The command +USET also displays Tot Ec/Io as one of its outputs.

+ETFCI?

+ETFCI=<status>

Supporting modems:

• MC879x(V) (min.

FW: K1_1_1_1ap)

Enable / disable / query E-TFCI average value

This command enables/disables checking of average E-TFCI values during

an HSUPA call.

The average value is based on 64 sets of log values extracted from the

E-DPCCH packet:

• every 200 ms (for 10 ms TTI) — each set includes 20 samples. A total of

1280 samples are taken (200 ms/set, 20 samples per set, 64 sets over

12.8 second period).

• every 80 ms (for 2 ms TTI) — each set includes 40 samples. A total of

2560 samples are taken (80 ms/set, 40 samples per set, 64 sets over

5.12 second period).

Note: An HSUPA call must be in progress to obtain the E-TFCI.

Usage:

• AT+ETFCI? indicates if E-TFCI checking is enabled, and reports the total

number of samples and average E-TFCI value. For example:

+ETFCI:

Status: <status>

total samples 1280, average etfci <etfci>

• AT+ETFCI=<status> enables or disables the ability to check the average

E-TFCI value.

Parameters:

<status> (E-TFCI reporting status):

• 0 — Disabled

• 1 — Enabled

<etfci> (Average E-TFCI value over sampling period):

• Valid range = 0–127
