CDMA phones - Know the difference from GSM phones

A cell phone is probably the most used gadget in today's times, with a significant number of people carrying multiple handsets simultaneously. Truly, the field of communication has had a remarkable expanse into the lives of all kinds of individuals with a multitude of the world's leading brands entering into the domain. The usage might differ, for instance, someone might want to use their phones only for making and receiving calls, while others might want to access the internet, watch movies, play their favorite songs, etc. However, essentially, there are two kinds of services for calling – GSM and CDMA.

GSM is an abbreviation that stands for Global System for Mobile Communications standard for cell phones. It has been in existence since the 1980s. This services operates in the 900 MHz and 1800 MHz bands in India and Europe, and in the 1900 MHz band in the USA. The technology entails that usage of SIM cards to get connected to the service provider and make calls, send messages, and access the internet. These SIM cards are removable memory chips that contain data and other information needed to complete the connection. GSM basically works on the basis of TDMA, which fixes a specific time period for a frequency.

CDMA refers to Code Division Multiple Access technology, which is totally different in functioning from TDMA or GSM. In this service, the voice signal is first digitized and the following data is spread over the frequency bandwidth. Thus, CDMA is basically a spread spectrum, which means that data is sent in small packets via different discreet frequencies that are available within the range at any point in time. This technology operates on both, the 800 MHz as well as 1900 MHz bands.

The basic advantage of CDMA is that the call rates are a lot cheaper than GSM. Also, the call quality is better due to the technologies used in both the cases, comparatively. GSM, on the other hand, has a lot more to offer in terms of advantages. First of all, there are numerous handsets and service providers to choose from, unlike CDMA, that has only a couple of options in terms of the latter, and a handful in terms of the former. Next, one is not bound to a particular service, and can change it any time in case the facilities are not good, calls are expensive, and so on. This kind of freedom can't be exercised in case of CDMA, where the handset and connection come together in a contract. Further, the power consumption on the part of the handset is lesser in case of GSM, compared to CDMA. On the connectivity part as well, GSM scores high, since the phone will work in any part of the world, unlike CDMA.

However, irrespective of whichever platform one chooses to communicate, Samsung, the world's leading brand and mobile phone technology, has high-quality options for all kinds of requirements. So, be it CDMA or GSM, there's always a Samsung to facilitate flawless communication in every form.
