CDMA (Code Division Multiple Access)

Code Division Multiple Access (CDMA) is a communication technology that allows multiple users to share the same frequency band by assigning them unique codes. Unlike traditional methods that allocate distinct time slots or frequencies to each user, CDMA spreads signals over a wide bandwidth. This means that many users can transmit data simultaneously without interference. The unique codes help the receiver separate and decode each user's signal despite the overlap. CDMA is commonly used in mobile phone networks, enabling efficient and reliable communication even in crowded environments. It enhances capacity and security in wireless communications.
