Let’s assume that the C/I is OK.
you will have a problem when using the same BCCH…
When a MS performs a HO from A to F, what does it mean ? The MS will have to send a HO ACCESS (burst message) towards F.
If the MS is sent on the BCCH of F, the HO ACCESS is sent on frequency BCCH(F).
This burst message will be understand as a RACH ACCESS by the cell G ! It might lead to SDCCH congestion on cell G… Not very critical, but yet, worth noticing.
Ok, that’s about it…
