Network coverage: Network coverage doesn’t depend on whether it is a GSM or CDMA network, but rather on the infrastructure the carrier has in place. GSM networks are far more popular globally, but The GSM network is using the frequency spectrum between GSM 850 MHz and GSM 1900 MHz to operate. A network tower in each GSM cell serves a phone located in its area of coverage while the CDMA establishes a physical channel and a dedicated code for each device in the network. GSM connections are SIM-specific. CDMA connections are device-specific. Radiations: They expose their users to higher level of radiations.

China Unicom, Kinas näst största mobiloperatör, försöker nu övertyga sina kunder att byta till CDMA-telefoner, som de påstår ger bättre mottagning och mindre  Since its inception, GSM has evolved faster than CDMA. WCDMA is considered the 3G version of GSM technology. To further speed things up, the 3GPP (the GSM governing body) released extensions called Technically GSM (Global System for Mobile communications, originally from Groupe Spécial Mobile) is a specification of an entire wireless network infrastructure, while CDMA relates only to the air interface — the radio portion of the technology.

- W-CDMA technology is faster than GPRS, since the user cares about the technology that is applied for air interface. - Average latency on GPRS is around 1.3 seconds, where as on CDMA is around 400 milli second - GPRS supports only User Datagram Protocol, where as CDMA supports both UDP and TCP

If you have an older phone, it might be restricted to As GSM is an international standard, so it’s better to use GSM in international roaming. GSM is in use by 76% of users as compared to CDMA which is in use by 24% users.

2019-10-06 Data Transfer Speed A variety of cellphones. Both technologies can be used with 3G standard phones, but 3G GSM speeds can be faster than 3G CDMA speeds, which can make a big difference for those who use their phones for social networking, email and streaming video. The fastest 3G standard used with CDMA2000 is EV-DO Rev B., which has downstream data rates of about 15.67 Megabits per second A GSM is more flexible than CDMA as the SIM can be replaced with other GSM devices. A CDMA is not flexible. 12: GSM phones emit continuous wave pulse. Thus, there is a need to reduce the exposures to electromagnetic fields. CDMA phones do not have these pulses.

Advantages of CDMA. One of the main advantages of CDMA is that dropouts occur only when the phone is at least twice as far from the base station. Thus, it is used in the rural areas where GSM cannot cover.

In other words, CDMA is a handset-based standard, with a phone number linked to a particular device.

They do not expose users to large amounts of radiations. Data Transfer Rates: GSM has slower data rates when compared to CDMA. CDMA has faster data transfer rate when compared to GSM. Differences Between GSM and CDMA 1. Technology Used The GSM is based on the wedge spectrum technology, also known as a carrier. This carrier is split 2.

GSM is a Time Division multiplexing scheme. Each channel is divided up into 8 time slots, and eight users can simultaneously use the same channel, with each user getting one slot in time. So your device transmits and receives when it's “its turn”
