It uses Time Division Multiple Access methods for transmitting a signal in an 850 MHz – 1900 MHz frequency band.Used in Voice as well as data services (SMS and MMS).This digital, Circuit-switched mobile technology widely embraced by all over the world, and it enjoyed 80% global market share at its peak.Developed by Europeans in the 1980s as Groupe Special Mobile standard, adopted by Asia,.3G/4G technologies replaced GSM/CDMA, but the basic concepts of GSM/CDMA were used in building the new standards, and it is only a virtual extension of old technologies. 2G technology reigned in the 1990-2010 time period, and it could not cater to the data requirements of new digital applications. Let us discuss some key differences between CDMA vs GSM in the following points:ĬDMA (Code Division Multiple Access) and GSM (Global System for Mobile communication) belong to the second generation of digital mobile standards (2G), and they replaced first-generation (1G) Analog standards.

In this article, we will analyze the features of GSM, CDMA and compare them. CDMA and GSM are the most popular standards for mobile communication, and many of the latest generations of mobile technologies were built on the fundamentals provided by GSM and CDMA. This technology paved the way for quicker adoption of new digital technologies like IoT and opened up many new business opportunities. Mobile technology spread its wings to connect moving entities like automobiles, ships, and airplanes to monitor their location and track their performance as well. Data transfer facility over and above voice connectivity enabled people to share data on the move. Cellular network, being wireless, saves costs on physical media like Cable and its cumbersome maintenance. Cellular technology using radio frequency wave enabled wireless last-mile connectivity to the users and kept them connected even when they moved from one place to another.
