CDMA is a digital technology for transmitting data. It is a general technology utilized through various standards. CDMA has no limit on capacity but the base station will only connect users upon determining that the call quality would fall bellow a predetermined limit. The term is often used to refer to one specific family of technologies – IS-95 (often referred to cdmaOne) and CDMA2000. Networks using this technology operate in the 800 and 1900 MHz frequency bands and are primarily used in the Americas and Asia.
