The fundamental idea with OL/UL subcells is that traffic close to the site is
moved to the OL subcell, while the traffic closer to the cell border is moved
to the UL subcell. By controlling the traffic in this way, the frequencies in the
OL subcell can have a tighter reuse.
But is it possible the frequencies
to be only from GSM900 band, or i should implement DCS. And the number of HO will increase with this OL/UL feature, yes?
So should i worried about the efficiency of the system.And finally can i implement this where i wont or i should take care.
