Short for Code-Division Multiple Access, a digital cellular technology that uses spread-spectrum techniques. Unlike competing systems, such as GSM, that use TDMA, CDMA does not assign a specific frequency to each user. Instead, every channel uses the full available spectrum. Individual conversations are encoded with a pseudo-random digital sequence. CDMA consistently provides better capacity for voice and data communications than other commercial mobile technologies, allowing more subscribers to connect at any given time.
Super 3G is a wireless networking standard for mobile phones that may offer wireless downlink speeds as high as 100 megabits per second. Super 3G is the next stage in the evolution of the existing 3G standard. 3G refers to the third-generation of mobile communications technology and promises increased bandwidth – 384 kilobytes per second kbps for a stationary or slow-moving device, 128 kbps in a moving vehicle, and 2 Mbps for fixed applications. It works over wireless interfaces such as GSM, CDMA, and TDMA.
