Hi everybody,

I just discovered this website and it’s very interesting. I’m working on the RF eng. crew of a mobile operator. I’ve observed “TCH sudden” (Ericsson equipment) is, in most cells, the first cause of drop calls. I want to know the relation between drop calls by sudden loss and optimisation of frequency assignment, particularly on frequency hopping and MAL lists as the TRU that carries traffic are TCH’s with hopping.

Thank you everybody.
