Difference between gsm and cdma

Question

GSM means it is a Time division system and cdma means it is a code division system

Abhinav Akash · Answer

GSM stands for Global System for Mobile Communication, and unless you live in the United States or Russia, this is probably the technology your phone network uses, given it’s the standard system for most of the world. GSM networks use TDMA, which stands for Time Division Multiple Access. TDMA works by assigning time slots to multiple conversation streams, alternating them in sequence and switching between each conversation at very short intervals. During that interval, the phones can transmit their information. In order for the network to know which users are connected to the network, each phone uses a subscriber identification module card, or SIM card.
Code division multiple access (CDMA) describes a communication channel access principle that employs spread-spectrum technology and a special coding scheme (where each transmitter is assigned a code). CDMA also refers to digital cellular telephony systems that use this multiple access scheme, as pioneered by QUALCOMM, and W-CDMA by the International Telecommunication Union (ITU), which is used in GSM’s UMTS.

There are many difference between GSM and CDMA. ... GSM stands for Global System for Mobile whereas CDMA stands for Code Division Multiple Access. GSMuses both FDM and TDM whereas CDMA uses CDM. GSM is widely used technology whereas CDMA is less used technology.

Prachi Padmakar Digraskar · Answer

GSM is "globle system for mobile" and CDMA is "code division multiple access". These are discovered for celluler phone networks. well GSM is GSM is a time division system, whereby voice is broken down in to smaller parts and transformed in to digital data. This data is then allocated to a channel and a time slot, then when there are multiple calls happening on one line, the receiver is able to ‘listen’ to the specific channel and time slot, combine the data and replay the voice.CDMA is a code division system, whereby each call’s data is encoded with a unique key, then the calls are all transmitted at once. The receivers then use a unique key to divide the combined signal back in to individual voice.

GSM- Global system for  Mobile access CDMA- code Division multiple access .Both are mobile communication Standards.
CDMA is handset bound that is it requires only cdma service provider handset only where as GSM not requires such service provider hand set, It can place in any of handset

Divya John K · Answer

GSM-Global System for Mobiles and CDMA- Code Division Multiple Accessing. In CDMA ,the user shares same channel, each users are given with unique codes. Whereas in GSM, the user seperated by frequency channels

GSM means global system for mobile communication.It is operated on narrow band freq.
CDMA means core division multiple acess .it is an spread spectrum analysis, so it is an wide band freq,

Burra Radhika · Answer

GSM means Global system for mobile communication system it is a 2G and GSM Developed by Europian standard  ,in GSM one frequency we can use multple users 
CDMA means code decimal multiple access it is developed by american standard and in cdma every user has different frequency

Nikhil Chakravarthi.D · Answer

GSM (Global System for Mobile communications) is a specification of an entire wireless network infrastructure. GSM digitizes and compresses data, then sends it down a channel with two other streams of user data, each in its own time slot. It operates at either the 900 MHzor 1800 MHz frequency band.
.
CDMA (Code division multiple access) describes a communication channel access which employs spread-spectrum technology and a special coding scheme. CDMA is a form of multiplexing which allows number of signals to occupy a single transmission channel, optimizing the use of available bandwidth. The technology is used in ultra-high-frequency cellular telephone systems in the 800-MHz and 1.9-GHz bands.
