CDMA allows up to 61 concurrent users in a 1.2288 MHz channel by processing each voice packet with two PN codes.
Read moreWhy a given bandwidth is used most efficiently in CDMA?
CDMA technology claims that its bandwidth is thirteen times efficient than TDMA and forty times efficient than analog systems. CDMA also have better security and higher data and voice transmission quality because of the spread spectrum technology it uses, which has increased resistance to multipath distortion .
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.
Read moreWhat is the frequency band for is 95 CDMA system?
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 .
