3.5.4.4.4 Signal Quality - +CSQ

+CSQ - Signal Quality

AT+CSQ Execution command reports received signal quality indicators in the form:

+CSQ: <rssi>,<ber>

where

<rssi> - received signal strength indication

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

<ber> - bit error rate (in percent)

0 - less than 0.2%

1 - 0.2% to 0.4%

2 - 0.4% to 0.8%

3 - 0.8% to 1.6%

4 - 1.6% to 3.2%

5 - 3.2% to 6.4%

6 - 6.4% to 12.8%

7 - more than 12.8%

99 - not known or not detectable

Note: this command should be used instead of the %Q and %L commands,

since GSM/WCDMA relevant parameters are the radio link ones and no line

is present, hence %Q and %L have no meaning.

Currently <ber> is available only in GSM network

AT+CSQ=? Test command returns the supported range of values of the parameters

<rssi> and <ber>.

Note: although +CSQ is an execution command without parameters, 3GPP

TS 27.007 requires the Test command to be defined.

3.5.4.4.5 Indicator Control - +CIND

+CIND - Indicator Control

AT+CIND=

[<state>

[,<state>[,…]]]

Set command is used to control the registration state of ME indicators, in

order to automatically send the +CIEV URC, whenever the value of the

associated indicator changes. The supported indicators (<descr>) and their

order appear from test command AT+CIND=?

Parameter:

<state> - registration state

0 - the indicator is deregistered; there’s no unsolicited result code (+CIEV

URC) automatically sent by the ME to the application, whenever the
