Re: [Discuss-gnuradio] [USRP-users] best transmitter/receiver setup for large coverage

[Lin HUANG]

Dilip,

So you just use CORNET remotely. Well, I think you should try different parameters... 

They use Custom developed USRP2 daughterboard based on the Motorola RFIC4. I didn't find "specifications on the "custom daughterboard"" in the FAQ.

Lin,

actually it is under the building please check here CORNET.

1 km is a long distance, so the lower frequency, the less pathloss. Use maximum tx gain and rx gain. 

And the distance may highly depend on the environment. Is there buildings, trees, or just a blank space?

Hi,
 
I am using usrp2 and gnuradio 3.3.0.
I want to use benchmark_tx.py as transmitter and benchmark_rx.py as receiver.
so that multiple receiver at distance of around 1 KM should get good signal strength.
 
So could you please let me know the best options for tx and rx waveform, so I could get the maximum range of coverage.
best options means:

transmitter frequency, tx gain, tx amplitude and rx-gain, if there is any other then let me know.
 
I need this to do spectrum sensing with energy detection.
 
with Thanks,
Dilip
