Thanks Pix,
Suppose we are near a cell with a TEMS and we know the BCCH of it,for example BCCH=25.
I mean MS not only measures this ARFCN(25)and camps on this cell but also MS measures two adjacent frequencies which are 24 and 26.
There is no any external interfernce.I found it by changing the BCCH (for example to 32) so I could see two adjacent frequencies again (which are 31 and 33).
What is your idea now?
