Hi Masters,
Some site have upload throughput better than download, i have test many time, any one can help me?
i have test many time
UL = 1,7mbps DL=0,05mbps
UL = 1 mbps DL=0,02mbps
UL = 1,1 mbps DL=0,03mbps
UL = 0,7mbps DL=0,05mbps
:o
what suppose to check?
thanks
You need to check transport utilization. i have same experience/symptom , and the root cause is bottle neck on transport (can be Iub, or concentrator, or IuPS). after i upgrade BW it solved.
maybe you can check packet loss on Iub level or IuPS level on busy hour.
Hi
You can check IUB Congestion M5000C176 , M5000C177 , M5000C178 , M5000C453 & M5000C7 are Conters to check IUB Congestion in NSN System .

probably you need to consistency check parameter with normal sites. if all of them is OK the next candidate probably transport
Oh ya one more,
Make sure your DL MIMO mode is spatial multiplexing or RI 2.

the first thing you have to check as always is the radio condition...then drill down further to interfaces and etc.

Hi,
Ask your transport group what is the defined/provisioned BW from NodeB up to RNC.

It has no relation because UL Thr is very good as per test result !Quote:

check also modulation used in DL (64QAM)
check Iub BW , Iub Congestion .......,
PS/ From you stat also the UL Throughput is Low , do you have TTI 2ms ?
Hi,
Ask your Transport counterpart what is the provisional BW for both UL/DL.
FYI...
