Difference between CDMA and GSM

CDMA (Code Division Multiple Access) and GSM (Global System for Mobile Communications) are two different types of cellular technology used for mobile networks.

CDMA is a type of multiplexing that divides the available spectrum into multiple channels by using spread-spectrum technology and a unique code for each call. This allows multiple users to share the same frequency band simultaneously. CDMA is primarily used in North and South America, and some parts of Asia.

GSM, on the other hand, is a time-division multiplexing technology that uses time slots to separate different calls. GSM also uses SIM cards, which store subscriber information and allow users to easily switch between devices. GSM is the most widely adopted cellular technology worldwide, and it is used in most countries outside of North and South America.

The main differences between CDMA and GSM are the type of multiplexing they use and the types of devices and SIM cards that are compatible with each network. Additionally, CDMA is considered more secure than GSM because it uses a unique code for each call, making it more difficult for unauthorized users to intercept calls. GSM is considered more widely adopted worldwide, allowing for global roaming and a larger selection of devices.
