Regarding all this clarification:
1) is there any difference at intra HO performance between non syncronised 900/1800 & syncronised 900/1800.
2) In case of syncronised 900/1800, what the effect of implementing COMMON BCCH on intra HO.
3) the effect of syncronised 900/1800 on the radio network feature (FH, DTX, Allocating, assignment, cell reselection(idle mode),… etc
4) is there any SDCCH signaling on 1800 band in case of COMMON BCCH.
# sorry for my too much interrogation, but realy I need some one to clarify it, or provide me by some related DOCUMENT.
