The CDMA channel is nominally 1.23 MHz wide. CDMA networks use a scheme called soft handoff, which minimizes signal breakup as a handset passes from one cell to another. The combination of digital and spread spectrum modes supports several times as many signals per unit of bandwidth as analog modes.

CDMA allows up to 61 concurrent users in a 1.2288 MHz channel by processing each voice packet with two PN codes.
Read moreWhat is the frequency range of CDMA?
As the term implies, CDMA is a form of multiplexing, which allows numerous signals to occupy a single transmission channel, optimizing the use of available bandwidth. The technology is used in ultra-high-frequency (UHF) cellular phone systems in the 800 megahertz (MHz) and 1.9 gigahertz (GHz) bands.

The IS-95 CDMA system operates in the same frequency band as the AMPS using frequency division duplex (FDD) with 25 MHz in each direction. * The uplink (mobile to base station) and downlink (base station to mobile) bands use frequencies from 869 to 894 MHz and from 824 to 849 MHz, respectively.
Read moreWhat CDMA used for?
Code Division Multiple Access (CDMA) is a sort of multiplexing that facilitates various signals to occupy a single transmission channel . It optimizes the use of available bandwidth. The technology is commonly used in ultra-high-frequency (UHF) cellular telephone systems, bands ranging between the 800-MHz and 1.9-GHz.
Read moreWhat is the RF bandwidth required for CDMA IS-95 standard?
Similar to most other digital vehicular cellular systems, IS95 uses speech coding at about 9.6 kbit/s .
Read moreWhat are the channels used in CDMA?
The Forward CDMA channel is the cell-to-mobile direction of communication or the downlink path. It consists of four types of channels to transmit voice and control data to the mobile. The types of forward link channels are Pilot, Sync, Paging and Traffic channels .
