Hi,
I have used USRP N210 with CBX40 at 1.18GHz
I got a low performance when two USRP N210 communicate
I used 'benchmark_tx.py' and 'benchmark_rx.py' located at ~/gnuradio/gr-digital/example/ofdm
Commands I used are below each other :
Tx) ./benchmark_tx -f 1.18G -m qpsk --tx-gain=31.5 -W 2500000
Rx) ./benchmark_rx -f 1.18G -m qpsk -W 2500000
(other options are default : packet size = 400, fft = 512, occupied toens = 200, etc.)
And I counted how many packets are received at Rx machine
Then I calculated throughput on Rx during 60 sec with below equation :
Throughput[bps] = (# of total packet - # of error packet) * 8 * 400 / 60
I derived about 1 Mbps at Rx and I think it is too poor
Am I something missing ?
So, I ask USRP N210 users to try that and tell me how about yours.
Thanks.
