Dear All,

What is the formula in calculating
EC/IO and RSCP

Thanks

Wow, thats quite a question if you really need the formula – which I cant see you needing a reason for. The formulas for both are probably contained in the propogation tool used by your company, and measurements carried out in the handset and BTS.

All you really need to know about the levels for both are what is acceptable and what is not for various areas/types.

Its generally accepted that EC/IO is good enopugh around the 14dBm level, and a decent signal level (RSCP)is up to -100 (again, these are dependent on clutter types).

The lower the level of RSCP then the more chance there is of degradation in the signal, and the more chance of noise being introduced as external sites shooting into the area have a greater effect on the S?N ratio.

Hope this helps
