Re: Answer the question

by Rana Ahmed -
GSM stands for Global System for Mobile communication, while CDMA stands for Code Division Multiple Access GSM uses FDMA (Frequency division multiple access) and TDMA (Time division multiple access). GSM supports transmitting data and voice both at once, but CDMA have not this feature.

The main distinction between GSM and CDMA is that in GSM, the customer information is put on a SIM card which can be moved to a new mobile phone. Whereas only mobile phones from a set of whitelisted companies can be used with a CDMA network. The call quality of both nationwide networks heavily depends on the network coverage. GSM users can experience better voice quality than CDMA users or vice versa in particular areas. Furthermore, the GSM network can transmit voice and data simultaneously. On the other hand, not all CDMA phones can transmit voice and data at the same time. In addition to the network congestion, CDMA call quality tends to be better than GSM.

At one corner, GSM operators say it is better “because it uses a SIM chip, it is the most used technology worldwide, it is more secure and it is more advanced”.

GSM operators claim that it is superior, because it employs a SIM chip, it is the most widely used technology in the world, it is more secure, and it is more advanced. In some places, GSM users may have higher sound quality than CDMA users and vice versa. However, not all CDMA phones can simultaneously transmit voice and data. Aside from network congestion, CDMA call quality is often superior to GSM.

CDMA is superior to GSM. In some regions, GSM users may have higher sound quality than CDMA users and vice versa. However, not all CDMA phones can simultaneously transmit voice and data. Aside from network congestion, CDMA call quality is often superior to GSM. When compared to GSM, CDMA provides a quicker data transfer rate. It employs the EVDO data transmission technology, which allows for download rates of up to 2 Mbps, whereas GSM uses the EDGE technology, which allows for download speeds of up to 384 kbps.

I think CDMA is better-advanced technology than GSM. GSM users can experience better voice quality than CDMA users or vice versa in particular areas. On the other hand, not all CDMA phones can transmit voice and data at the same time. In addition to the network congestion, CDMA call quality tends to be better than GSM.CDMA offers a faster data transfer rate as compared to GSM. It uses the EVDO data transfer technology that offers maximum download speeds of 2 Mbps while the EDGE technology the GSM uses offers maximum download speeds of 384 kbps.

GSM operators claim that it is superior, because it employs a SIM chip, it is the most widely used technology in the world, it is more secure, and it is more advanced. In some places, GSM users may have higher sound quality than CDMA users and vice versa. However, not all CDMA phones can simultaneously transmit voice and data. Aside from network congestion, CDMA call quality is often superior to GSM.

GSM stands for Global System for Mobile communication, while CDMA stands for Code Division Multiple Access GSM uses FDMA (Frequency division multiple access) and TDMA (Time division multiple access). GSM supports transmitting data and voice both at once, but CDMA have not this feature.

The main distinction between GSM and CDMA is that in GSM, the customer information is put on a SIM card which can be moved to a new mobile phone. Whereas only mobile phones from a set of whitelisted companies can be used with a CDMA network. The call quality of both nationwide networks heavily depends on the network coverage. GSM users can experience better voice quality than CDMA users or vice versa in particular areas. Furthermore, the GSM network can transmit voice and data simultaneously. On the other hand, not all CDMA phones can transmit voice and data at the same time. In addition to the network congestion, CDMA call quality tends to be better than GSM.

At one corner, GSM operators say it is better “because it uses a SIM chip, it is the most used technology worldwide, it is more secure and it is more advanced”.
