[Discuss-gnuradio] On the maximum transmission distance

Hi,

 

I am sure someone has tried to find out the maximum transmission distance using USRP2. For example, I am interested in the maximum transmission range in the following setting:

 

USRP2 with WBX, 400MHz/900MHz, outdoor, los, static, benchmark_tx/benchmark_rx with default except tx_gain=25 (maximum).

 

We are interested in extending the transmission range by adding external amplifier module. If anyone can share the experience, it would be greatly appreciated.

 

Thanks,

An
