Hi Fresh Opt,
Sorry for my mistake: instead of location update load I have written paging load.
So, for my opinion defining 2 LACS for one city, is important to avoid location update load, between border cells, as much as possible.
LACS borders is better to be choosen between cells that aren’t very good adjacent cells with each other (based on traffic sharing), so in this case we avoid to much location update between them.
Hope I was clear 🙂
