USRP_Result - pchat-imm/o-ran-e2-kpm GitHub Wiki
Description: result of run srsRAN_Project for 5G using USRP B210
- Result
tested scenario
UE is CPE (ZLTX)
- speedtest (gNB trace, and UE speedtest)
- IPerf to specified server
- youtube watching
UE is CPE (WLink G230)
- speedtest + iPerf
2CPE
- iphone to WLink CPE, and RPI to ZLTX CPE - youtube on both end device
UE is RPI + Quectel
- increase RSRP of the transmitted signal from the SDR to the UE
- ping from UE to the Core network (UE = RPI + Quectel)
- access web server from UE (UE = RPI + Quectel)

note
- although one UE connect, it still can show vary of
rnti(4615 -> 4616 -> 461e)
- captured speedtest and iperf client on a mobile phone that connec to the UE (CPE)
-
when ran with multiple UE, check
RNTI, which is 4603 and 4604
