If not, then why? both is the Interference ratio… Plz Explane.. 3rd November 2011 at 10:46 #67465 pixGuest hi malay, yes, they are similar. but the “range” of values are difference. In GSM for example, C/I goes from 0dB to 40dB. A good C/I is > 9dB. With Ec/No and Ec/Io, the ranges are different. One of them is negative (forgot which one) regards pix 4th November 2011 at 10:00 #67466 MalayGuest Thanks Pix..
