    Dear Pix,
    Can you help me with the problem of call drop(TCH)after the Overlaid and Underlaid Subcells implementation. From TEMS I didn`t find drop but stat 20% drop is seen.

    Hi RK,

    Stats will help u finding if ur drops occurs in Overlaid or Underlaid subcells.Try to lock ur TEMS into band that got high drops , do tests and u could probably see the cause.

    Thanks.

    Dear ATTO,
    the neighborlist 0f 900 also has 1800 but i think it is not required and Rxlevel of 1800 is -100 dBm. since the BCCH is only 900 so do i need to lock the Band?

    Hi RK,

    Tuning will depend on what config do u wanna have: more or less traffic in 1800 band?
    The reason u’ve got no drops when drive testing is probably that ur call has been holding by the less “interfere” band probably the 1800? And problem can occur only cell got loaded.
    So u must check first the call drops statistics per band; it exists within E/// and then do drive test by takin special look at that band.
