ok

Basically in case CDMA RF planning we make use the PN codes i.e. Pseudorandom codes unlike GSM were we assign a BCCH freq to a cell.

In a CDMA system, a narrow-band message signal is multiplied by a spreading signal, which is a pseudo-noise code sequence that has a rate much greater than the data rate of the message. CDMA uses these code sequences as a means of distinguishing between individual conversations. All users in the CDMA system use the same carrier frequency and may transmit simultaneously

Reverse Link 824 – 849 MHz
Forward Link 869 – 894 MHz

moreover in case of CDMA thee are “Soft Hanoff’s”.
