Well thanks for the info
Its not the spectrum of CDMA which interferes sometimes ..Sometimes its the harmonics of the CDMA which may interfere..Although there always has to be a gaurd band between GSM & CDMA..But the harmonic(byproducts) have varying amplitude & frequency create the problem of interference. So, I personally think interference of CDMA on GSM uplink is irrespective of GSM/EGSM..
Need more discussion on this…
