#JDRENH2 – Enhanced Jammed Detect & Report 2
5 - enables the Jammed Detect; the MODULE will make both the actions as for
<mode>=1 and <mode>=4.
6 - enables the Jammed Detect (this value is available only for 10.00.xxx release);
the Jammed condition is reported in the format:
#JDR: <status>
where:
<status>
JAMMED - Jammed condition detected
OPERATIVE - Normal Operating condition restored. This code will be
shown only after a jammed condition has occurred
UNKNOWN – default state before first successful PLMN searching
NOTICE: if you change the
parameter of the
command, it will be automatically changed the
parameter of the
command, without notice.
- Set the starting absolute threshold of RxLevel 2G Network.
After a frequency scan in 2G bands, if the power measured of a carrier is
above of <
> that carrier is counted as possible jammed carrier.
0...63 (Factory default is 45).
<
> - Set the starting absolute threshold of RSSI 3G Network.
After a frequency scan in 3G bands, if the power measured of a carrier is
above of <
> that carrier is counted as possible jammed carrier.
0...63 (Factory default is 35).
<
> - Set the minimum number of possible jammed carriers to
consider that the module is under jamming condition.
0…200 (Factory default is 100).
<
> - Set the threshold of RxLev in 2G Network. The
threshold (RxLev_Thr) is calculated as
RxLev_Thr=RxLev_Av*(1+(<
>/100)) where RxLev_Av is the
average of the last 10 RxLev measures.
0…100 (Factory default is 15).
<
> - Set the threshold of EcN0
in 3G Network. The threshold
(EcN0_Thr) is calculated as EcN0_Thr= EcN0_Av*(1-(<
>/100))
where EcN0_Av is the average of the last 10 EcN0 measures.
0…100 (Factory default is 70).
