LTE Poor SINR and Interference issue Optimization

[kentck86]

Hi All,

Can anyone share on the experience of determine the Interference in LTE Network Optimization? Could anyone share how does the criteria of Interference are happening in LTE network? SINR<0? More than how many listed cell in the same point are defined as problematic area of interference? Any others measurement parameter shall we look into for this case?

thank you

Is it interference or elevated Noise? your KPIs should show you >-92 dBm. what system is this E///?

SINR affect your CQi.. anything below 10 will not have a good QAM ..try and control RF overshoots/ DT/ change -out antennas - use higher gain (8ft if possible) . try and have 1 dominant server in poor RF . adjust your qRXlevmin. try and h/o to 3G wherever possible at the edge of coverage (IRAT)

For LTE, do we have any criteria like this? thank you
