Re: [Discuss-gnuradio] Ettus Research Announcements -- Nov 2010

[Steve Mcmahon]

Hello Matt:

Sorry, one more question. Will the USRP N210 still support the raw Ethernet 
interface to the host (like for the USRP2), or will it only support the new UHD 
interface?

Secondly, what is performance penalty of UHD interface versus the raw Ethernet 
interface? UHD is based on UDP, so certainly there must be some reduction in 
the maximum data rate (and thus the bandwidth) compared the raw Ethernet 
interface. UDP certainly adds overhead...

Finally, if the USRP N210 only supports the new UHD interface, what is the 
reason that the current raw Ethernet interface is being deprecated in favor of 
UHD? What are the advantages of UHD compared to raw Ethernet? What are the 
disadvantages?

Thanks a lot for answering all these questions!!
