CDMA is a mobile network technology that has evolved through several generations. It started as an alternative to TDMA and FDMA used in early mobile networks. Modern CDMA uses techniques like OFDM, MIMO and cognitive radio to provide faster data rates and cleaner signals compared to older standards like GSM. Future advancements in CDMA will involve new hardware to support these technologies as well as improvements to devices like flexible displays, better cameras and longer battery life.
