    Default Narrow-Band Interference suppression(NBIS)

    Hii Friends,
    The Narrowband Interference Suppression feature helps suppress narrowband interference on UMTS 900 MHz, 850 MHz, 2100 MHz, 1900 MHz, and AWS bands, improving network performance and user experience.

    Dears,-Have you applied this feature for all cells? or specific cells [which threshold please]?-How did you know that the existing interference in your network is narrowband?

    yes, if i found bad rtwp case, NBIS applied for all cells, but need to check RRU first, cause some RRU not support NBIS, after applied you need check the alarm also.
    the threshold is different values ​​between cells, for example, sector 1 & sector 2 (-105), but sector 3 (-80), with run FFT test you can analyse the interference
