I dont know why everyone is giving different kind of solution.
Lets go for futher discussion practically.
for example in 8rth floor the serving sites are
A- rxlev- -55dbm(average)
B- rxlev- -62dbm
C- rxlev- -68dbm
D- rxlev- -75dbm
E- rxlev- -50dbm
indoor site with dedicated frequency band- -45dbm.
now please tell me you r user in 8rth floor. to which cell or sector your mobile will latch and why? Will it always latch with the indoor one? What difference it will make if i give different values of C1 and C2 to every site or sector or what value i should give to indoor cell?
