    High ICM band ( 2 and up) means there is interference on TCH and SD channels on Idle mode. do frequency scanning on the area to identify the cause of inter fences and check for hardware issues (jumper, connectors ) on antenna system installation

    Hi Devendra,,
    Normally we are facing ICM band high in Combine DAS (IBS),
    Reason:
    1. due to connector not done in proper manor.
    2.which you used accessories for DAS that accessories not meeting PIM value.
    3.Fq interface in from the BTS end
    4.if we have DAS connectivity in Inside the BTS room then you need to reduce the BTS room radiation.

    Diffrent B/W MIMO & SISO: in single word we can say,MIMO means multi input multi output ,,,SISO single input single output

    Regards,
    Daya
