I have a Quectel M95 modem.
On my test gear, I notice that the radio is transmitting some kind of signal every 200mS.
Can anyone tell me:
a) what this signal is
b) what it used for
c) what i must do to change the interval at which its doing it.
hi Moose ,
I believe you are getting the DRx pulses . This is used for initmating NW that UE is alive and if any TAU is required .
This is used for saving battery for wireless device where module at periodic interval tell BTS that he is there.
Thanks for that…pardon my ignorance, but…
what is DRx
DRx – Discontinious reception
TAU – Tracking area update
BTS – Base station .
hi…thanks very much!
do you know if i can change the rate of DRx pulses?
No you can;t change in GPRS module , NBIoT based modules give those luxary to you .
in GPRS module DRX5 and DRX9 is used and it is decided by service provider according to its proximity and other parameters of module .
ratan, thank you once again for your knowledge.
my pleasure Moose . Thank you for using Quectel
