Adjacent frequencies (A), that is frequencies shifted 200 kHz from the carrier frequency (C), must be avoided in the same cell and preferably in the neighboring cell also. Although adjacent frequencies are at different frequencies to the carrier frequency they can still cause interference and quality problem.
The GSM specification states that carrier to adjacent ration (C/A) must be larger than 9 dB.

What is the value of Adjacent ratio(C/A) for Wi-FI(wireless).
