Hello everyone,
Before to explain my problem I give some technical information about my
hardaware. I'm using USRPs v1 and the boards integrated are XCVR2450
Transceivers.
I'm using the script usrp_spectrum_sense.py in a USRP to detect a signal in
a ISM channel. To have a signal expressed in db

Hi Nick,
I just wanted tell you that I solved my problem using interprocess
communication, thank you for your advice!

Hello everyone,
Before to explain my problem I give some technical information about my
hardaware. I'm using USRPs v1 and the boards integrated are XCVR2450
Transceivers.

I've got four USRPs and they are equal and the boards integrated are

Hello everyone,
I'm using a USRP platform with XCVR2450 Transceivers daugtherboard for
sensing experiments. I'm sweeping the WiFi band from 2.4 to 2.5 GHz knowing
which channels are used by the APs (i.e. Ch1, Ch6 and Ch11). I considered
the script usrp_spectrum_sense.py with a decimation factor e
about that? Thank you!

Hello everyone
I’m using an USRP with a XCVR2450 daughter board working at 2.4 - 2.5 GHz. I
want to find a threshold between thermal noise and signals energy using the
script usrp_spectrum_sense.py and sensing from 2.400 GHz to 2.500 GHz. To do
that, I replaced the WiFi antenna with a resistor of

I already read another post regarding a same problem as mine

but unfortunately I still don't understand how to solve it. I'm modified
benchmark code to receive a file by benchmark_rx and and to send i
How did you resolve your problem? I have the same problem and reading your
post I cannot understand the solution of your one.
Thanks in advance

You are right thanks, I solved the problem using higher bitrates

Hello everyone,
I have a problem with my USRPs that I cannot solve. I've got three USRPs and
they are equal and the boards integrated are XCVR2450 Transceivers. I'll
simply call them USRP1, USRP2 and USRP3 to be able to clearly explain my
problem. I want to transmit data from one USRP to another

I'm trying to utilize benchmark_tx.py and benchmark_rx.py using 2 USRPs with
XCVR2450 Transceivers. When I consider a bit rate equal or greater than 124k
everything works well. With bit rates smaller than 124k only the
