DYK? Cellphones are basically networked radios.
Currently, there are two major standards in use around the world:
CDMA vs. GSM: What’s the Difference?
CDMA (Code Division Multiple Access) and GSM (Global System for Mobile Communications) are two popular mobile network technologies:
1. Technology Approach:
• CDMA assigns a unique code to each call, allowing multiple users on the same channel.
• GSM uses time slots (TDMA) and frequencies (FDMA) to separate users.
2. SIM Cards:
• CDMA phones traditionally didn’t use SIMs (device-specific).
• GSM phones always use SIM cards, making it easy to switch devices.
3. Global Reach:
• GSM is widely adopted worldwide, ideal for global roaming.
• CDMA is more regional, mainly used in the US and parts of Asia.
4. Data & Speed:
• CDMA often provided faster data rates in 3G.
• GSM became more versatile with 4G LTE, leveling the playing field.
In today’s world, 4G LTE and 5G have mostly unified these differences, with most carriers supporting SIM-based LTE systems.
