LTE SPEED TEST TROUBLE SHOOTING
For Download Detail Full Speed Test Trouble shooting manual Click here
If there is issue in LTE Speed Test on all the sectors of the site then
please verify following steps.
1. SINR is above the target value . i.e SINR>25db
2. SINR is not fluctuating.
3. RSRP is above the target value. i.e RSRP>75dbm
4.Modulation Scheme is 64QAM.
5.Resource Block assignmentsis much lower than 100 on all the sector of sites.
After verifying the following scenarios go to bad RF Environment SINR<5.
Check the resource block assignment in bad rf environment, if resource block is still less and same as beofre then repeat the test in the off peak hours.
If resource block assignment increase significantly than before then raise the issue for backend support.
If speed test is less in FTP Testing then check the best availible server and repeat the test.
