    Default LTE Poor SINR and Interference issue Optimization

    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

    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)

    Hi sir,I am working with huawei equipment, just wanted to know is there any criteria of pilot pollution like (UMTS: >4th serving cell are in the range of 6dB then its consider the 4th and above cell are pollutant). For LTE, do we have any criteria like this? thank you
