Thanks Wilibrordus Herbowo!
If I may ask what do you mean by 1/3 enhence. I have already run the trial on 1/3 and 1/1. I had very good results with 1/3 than with 1/1 does any one know why? Because I did not expect that much difference as far as CDR, HO_DROP_RATE etc are concerned. the other thing I don’t think BBH is a good idea, in Siemens System if using BBH and one of the TRX involved in Hopping fails the system automatically diable Hopping(Frequency redefinition) until the affected TRX is brought back to service.
