Hi Malay Das,
I’m not sure but I think that each HSN number has its own hopping algorithm. With the same HSN in all cells (same algorithm, same rule) of a BTS using different MAIO (different frequencies in the same time) for each TRX you prevent interference.
With different HSN number in cells, so different algorithms, it means that is very possible using same frequency in the same time very often and that causes interference.
And, please, don’t use such a language any more. The best contributor in this forum is Pix. You shouldn’t do that. Shame on you. I’m sure you’re a nice guy and sometimes we all are angry about something.
Regards,
Rex
