Hi can anybody tell me how TCH Rf loss can be minimised. We are having few fringe sites, they have TCH Rf loss of 10.03 and call drop of 10.43 it is a fringe site so no question of severe interference, can u guys pls suggest what should i do.
You need to check overshooting of the cell and contain the coverage by tilting and also reducing Access Min Parameters (Depends on Vendor) ussually ACCMIN parameter (Cell level ) is set -110 and if you minimise to -102 or -100 dbm it will rediuce the overshooting.
Remember it is a trade off you will improve the coverage but reduce the traffic.
Otherwise install TMA (Tower Mounted Amplifire to improve UL coverage
