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 is GSM and types?
Global System for Mobile Communication aka GSM is defined as the digital network aiding mobile connectivity . The GSM network is used by people from different parts of the world and Europe, on a whole. Of the three variants, GSM, TDMA and CDMA, the former stands as the most popularly used network.
Read moreWhat is the difference between GSM and LTE?
GSM supports both cellular and data, whereas LTE is synonymous with high-speed wireless broadband technology that supports only data . This is why most of the new cell phones use LTE for high-speed internet access and rely on GSM for voice calls.
Read moreIs GSM is 4G?
GSM is a second-generation (2G) cellular technology standard and is, therefore, less capable of providing high-speed data as compared to UMTS, which is a third-generation (3G) technology and LTE, which is a fourth-generation (4G) cellular technology.
