Can anybody tell me how to increase transmitter power in USRPN210 ?
I guess you have 3 options:
* The digital amplitude of the samples. (The magnitude of a sample
should not exceed 1.0 when using complex floats)
* The transmitter gain (if the RF
With the UHD version, I can't get the transmitter to turn on,
regardless of input. If I connect the usrp_sink to a vector source
of 1s, the transmitter turns on, but not for very long. Is there
some way to force the transmitter to be on? I am using the RFX
series daughtercards. The
Although i have defined set_tx_amplitude and at run time i do provide the
user option --tx-amplitude value is set to 0.25 but it still transmits at
16dBm (max power of a USRP N200) when you would expect it to be around a
quarter of that power.
Any suggestions in this regard would be

Ok, thank you, I will take a look.
There are also a couple of squelch implementations that you might be
able to use. The uhd_burst_detector is kind of nice, though, in how it

Is there any advantage to use TUN/TAP interface ?
As 802.11bbn also uses TUN/TAP interface.
But I think in the tun/tap performance degrades as we send the packet back
to user process?
Therefore I compare results with benchmark_xx.py in /ofdm with tunnel.py
in /ofdm.
In results benchmark_xx.py do

connections are unidirectional flows of data.
You could however create two connections

Tun/tap is a convenient way to get access to the network stack from
userspace. Unfortunately the benchmark* apps abuse tun/tap as a mac
layer, which is precisely the wrong thing to do.
For example:
Cool.
How can I get this information at that time?
