Hi Ismael,

Thanks and Regards,

Hi Team,

  I was testing USRP X300/310 with COTS UE, as part of this I observed poor UL SNR i.e.., <10dB, some times it is as low as 2 to 3dB.I did not see this issue with USRP b210 boards.

I did play with rx_gain settings ( 30 to 130 ), but I did not notice much improvement. Any ideas/help here is much appreciated.

X300 config:
25 RBs
Hyperthreading disabled
10GB ethernet link between Host and USRP
Band7 UE
UEs: Samsung S7 and Fire phone

Thanks and Regards,
Venu
