Code Division Multiple Access (CDMA)
Code Division Multiple Access (CDMA) is a communication method that allows multiple users to share the same radio frequency spectrum simultaneously. It works by assigning a unique digital code to each user’s signal, spreading its data across a wide range of frequencies. When signals reach the receiver, the unique code helps to isolate and recover each individual signal from the others, improving security and reducing interference. This technique enables multiple conversations to occur at once over the same bandwidth, making it efficient and effective for wireless communication systems like cell phones.
