    The main task of optimization is to direct most of the traffic in more clear band 1800.
    HO_MARGIN – there are a lot kinds of handover – and for all of them there are different threholds (in most cases,for different GSM networks – different threholds)

    C1 and C2 are selected for each BTS.
    Directed Retry is better to set – Yes
