Hi Mania,
We mostly have FBOffset at 9dB but the 0 i referred to was Ericsson default.
If i may ask, why do u use TCC…we apply it for coverage mostly in rural areas where traffic is not that high. In densely populated areas where there is high traffic, we employ OL DCS 1800 for capacity, therefore no need for 1 site to cover a huge area.
