Questions about sending ping using USRP

Dear all

Hi, I have a questions about sending ping packet by using USRP N210.

ex. USRP Tx : 192.168.10.2 / USRP Rx: 192.168.10.3

computer1 - USRP tx  ---> wireless channel ---> USRP rx - computer 2

If I command the line "ping 192.168.10.3" in computer 1. Is it possible?

thanks

To use an analogy that might be easy to follow, the USRP N210 is part of a PHY (Physical layer) in the system you describe. It is a means to transform baseband samples that comprise a modulated waveform to and from an RF carrier frequency. The bits, packets and protocols that you implement on top of this physical layer are all implemented in S/W on the Host computers.
So the first device that computer1 can "ping" if you implemented an IP link over the USRP's would be computer2 once the S/W radio that runs there has demodulated the waveform, turned symbols into hard bits, reconstructed packets from the raw bits, and stripped MAC layer headers…at which point it would typically pass the now IP level packets via a virtual network interface into the hosts native TCP/IP stack.

The bits, packets and protocols that you implement on top of this physical layer are all implemented in S/W on the Host computers. So the first device that computer1 can "ping" if you implemented an IP link over the USRP's would be computer2 *once* the S/W radio that runs there has demodulated the waveform, turned symbols into hard bits, reconstructed packets from the raw bits, and stripped MAC layer headers…at which point it would typically pass the now IP level packets via a virtual network interface into the hosts native TCP/IP stack. -Ian On May 12, 2015, at 6:08 PM, 이재훈 via USRP-users <usrp-users@lists.ettus.com> wrote: > Dear all > > > > Hi, I have a questions about sending ping packet by using USRP N210. > > > ex.
