How Cdma Works
CDMA, or Code Division Multiple Access, is a cellular technology that allows multiple users to share the same frequency band at the same time. Unlike GSM, which uses Time Division Multiple Access (TDMA), CDMA employs a spread spectrum technique where each call is encoded with a unique code, allowing multiple users to communicate simultaneously without interfering with each other. This spreading of signals across the spectrum results in increased capacity and improved call quality.
In CDMA networks, each user is assigned a unique code that is used to modulate their signal. When a call is made, the voice data is digitized, encrypted, and then spread across a wide frequency range using the assigned code. At the receiving end, the receiver uses the same code to decode the signal and reconstruct the voice data. This unique coding and decoding process is what enables multiple users to share the same frequency band without causing interference.
CDMA technology is known for its robustness and ability to handle a large number of users efficiently. The use of codes to separate users allows for greater security and privacy in communication. Additionally, CDMA networks have been able to achieve high data speeds and support advanced services like mobile internet browsing and multimedia messaging.
